Space ‘Hotels’ to Slingshot between Earth and Mars

PURDUE

A newsletter for alumni & friends of the School of Aeronautics & Astronautics • Fall 2002covering the 2001–2002 academic year

Edwin “Buzz” Aldrin, the second man to walk on

the moon, is leading a team of researchers, including engineers at Purdue, to design a new class of spacious “cycler” spacecraft that would serve as orbiting hotels.

A family of three cyclers would perpetually cruise between Earth and Mars speeding along at 13,000mph to make continuous six- to eight-month interplanetary trips. Cyclers would take advantage of the gravitational forces that are exerted by the sun, the planets and their moons, which provide “gravity assists” to passing spacecraft. As a spacecraft travels close to a planet, its fl ight path is bent, causing it to whip around the planet while boosting its speed. The path is commonly called a “slingshot” trajectory, which enables a spacecraft to achieve the proper speed and heading.

“The cycler essentially is in orbit around the sun and makes regular fl ybys of Earth and Mars,” said team member James Longuski, professor of aeronautics and astronautics at Purdue. “Once you put your vehicle into a cycler orbit, it continues on its own momentum,

going back and forth between Earth and Mars. You may need to carry some propellant for an occasional boost, but it’s pretty much a free trip after that.”

Aldrin, a 72-year-old retired astronaut and former combat fi ghter with a doctorate in astronautics from the Massachusetts Institute of Technology, targeted 2018 for an inaugural fl ight. He has promoted his “cycler” idea for more than a decade through his ShareSpace Foundation. Aldrin is working with a team of researchers including academics at Purdue, the Massachusetts Institute of Technology and the University of Texas.

“We believe these regular planetary fl ybys would create an entirely new economic and philosophic approach to space exploration,” the researchers wrote in a December 2001 report prepared for NASA’s Jet Propulsion Laboratory. “Reliable, reusable, and dependable cycler transportation can be the key to carry humanity into the next great

AAE HeadlinesThe 2001–02 academic year brought much excitement to the School and Purdue. The board of trustees approved President Jischke’s strategic plan for the University entitled, “The Next Level: Preeminence,” in November 2001. Dr. Linda P. B. Katehi began her tenure as John A. Edwardson Dean of Engineering in January 2002. One key aspect of the University strategic plan is to increase the size of the faculty by 300. This dramatic increase in faculty size represents great opportunities for the School to invest in educational and research opportunities. The School is working closely with Dean Katehi to appropriate areas in which to hire faculty. We would love to hear from you about faculty candidates that would help the School reach “The Next Level.”

The School’s undergraduate enrollment increased by 18 percent to 345 in the fall of 2001,

and indications are that it will reach 400 in fall of 2002. The faculty continue their efforts to implement strategic planning goals of providing opportunities for hands-on team-based learning experiences as well as involving undergraduates in research. Your financial contributions are instrumental to enhancing these learning experiences and we thank you for your continued support.

We are pleased to report the addition of two new faculty members in the fall of 2001. Dr. William E. Anderson brings experience in propulsion with special expertise in combustion instability. Dr. Hyonny Kim brings experience in structures and materials with special expertise in composites. Bill and Hyonny bring the total faculty size to 22. It is also a special pleasure to report that the board of trustees has approved the promotion to professor of Drs. Tasos Lyrintzis and Mario Rotea. It is always wonderful to see colleagues be recognized for their contributions to students as well as their field of creative endeavor.

Highlights of the year included the 3rd William E. Boeing Lecture given by Dr. Jurgen Weber and the 3rd Annual Outstanding Aerospace Engineer celebration. These events along with Homecoming and Gala Week are wonderful times for you to return to campus. We always welcome you back to campus so

that we might show you up-close the educational opportunities that your support provides our students. Having you back on campus gives us the chance to say thank you for your support and, more importantly, connects you with our present students so that you too can know why we make educating Purdue aeronautical and astronautical engineers our life’s work. We strive to make the Purdue education live up to the standards that you remember so well.

The Millennium Engineering Building is a key part of the Engineering Master Facilities Plan (EMFP) and important to the School as it represents a once in a lifetime opportunity to enhance facilities for our students. Faculty members are also planning upgrades to facilities in the Aerospace Sciences Laboratories and the Zucrow Propulsion Laboratories. All of these facilities are important to the School as it continues progress to its goal of providing the very best educational and research opportunities for its students. The facilities investments will be a partnership between the State of Indiana, industrial partners and friends and alumni like you. We thank you for your support to date and look forward to your continued support in the future.

age of exploration, expansion, settlement and multi-planetary commerce.” The proposal is being offered as part of the space agency’s long-term planning process, looking as far as four decades ahead.

Because the spacecraft would never stop, the team envisages space “taxis” that would ferry passengers and supplies from the planetary surfaces to rendezvous with the speeding cycler craft. “This is like a bus that doesn’t stop,” said Professor James Longuski. “When it comes by, you have to run alongside and grab on. Then, when you get to Mars, you get in the taxi and de-orbit down to the planet.”

Longuski is working with Purdue graduate students to design “outbound” and “inbound” trajectories, or the trips from Earth to Mars and from Mars to Earth. It is difficult to precisely design cycler trajectories because of the complex orbital relationship between the two planets as they orbit the sun. While Earth orbits in a nearly circular route, Mars’ orbit is oblong or elliptical. And Mars takes 687 days to orbit the sun compared with Earth’s 365 days. That means that the distance between Mars and Earth varies dramatically depending on Mars’ orbital position around the sun, and can vary from 33 million miles to 250 million miles, complicating the design of spacecraft trajectories between the two planets. Determining the precise path for cyclers requires engineers highly

skilled in celestial mechanics who use mathematical techniques to create and evaluate numerous possible trajectories, eventually arriving at the best choice.

Longuski and his students have previously designed trajectories for an unmanned spacecraft to Jupiter’s moon Europa, which is tentatively scheduled for launch in 2006. The team also designed trajectories for a hypothetical manned mission to Mars.

The cycler spacecraft would have to encounter Mars and Earth at precisely the right distance and speed. If the approach was too fast or at the wrong distance, too much fuel would be needed for steering rockets, and it would be more difficult to “taxi” spacecraft to dock with the cyclers as they sped by. Cyclers would rotate slowly to create artificial gravity and prevent the debilitating effects of weightlessness on its passengers. The spacecraft would also be roomy enough to accommodate up to 50 passengers and would provide the usual creature comforts to make the trip tolerable.

“Some day, people will be going to Mars on a regular basis,” Longuski said. “Most people are convinced that we are going to do this; the only question is when.”

Dennis Byrnes Visits School of Aeronautics & Astronautics

Soil collected on the moon

by Purdue alumnus Eugene Cernan BSEE ’56, nearly 30 years ago has helped researchers both at Purdue and the University of California uncover new details about the working of the sun. Apollo 17 astronauts Cernan and Harrison Schmitt scooped the lunar soil up in 1972. They collected the largest lunar sample ever brought back to Earth—about 249 pounds, now stored at the Johnson Space Center in Houston.

Physicists at UC Berkeley and Purdue have analyzed the lunar soil samples for the presence of an element deposited on the moon’s surface by the solar winds, a stream of particles constantly being ejected from the sun. The

findings were reported in Science on October 12, 2001, in a paper written by Kuni Nishiizumifrom of UC Berkeley’s Space Sciences Laboratory, and Marc Caffee, an associate professor of physics at Purdue.

Cernan, who was the commander of Apollo 17, was the last man to walk on the moon. He earned a bachelor of science degree in electrical engineering from Purdue in 1956 and also holds an honorary doctorate from the University.

Earth and other planets are shielded from the solar winds by their atmospheric envelopes and magnetic fields. As the moon has no such protection, the solar wind is not kept from hitting the surface of the moon, making it a unique environment for such research. The research will reveal not only the sun’s workings, but it will also

provide new insights into how the sun and the solar system were formed 4.5 billion years ago.

Due to be launched in 2003, the purpose of SMART–1, the European Space Agency’s mission to the moon, will be to flight test the new Solar Electric Propulsion technology, which is a kind of solar powered thruster that is ten times more efficient than the usual chemical systems employed when traveling very long distances. Additionally, SMART–1 will map the moon more accurately than ever before, flying over all of the Apollo landing sites. Images taken from many different angles and X-ray and infrared detection work will allow scientists to

draw up a new three-dimensional model of the moon’s surface. SMART–1 will be looking at the darker parts of the moon’s South Pole for the first time, and it will accurately map the Peak of Eternal light, an eerie mountaintop that is permanently bathed in sunlight, while all around are dark craters never touched by the sun. These craters are believed to harbor ice in the soil. SMART–1 will help scientists to understand if ice is present at the lunar poles.

Purdue Ranks in Top 10Six of Purdue’s Schools of Engineering ranked among the top 10 in the nation in a survey published in U.S. News & World Report in April 2002. The ranking for the Purdue graduate-level programs put the School of Aeronautics and Astronautics in sixth place.

Overall, Purdue engineering ranked 12th in the nation, based on data provided by 145 schools. In a separate ranking category, corporate recruiters rated Purdue engineering sixth in the nation. In the fall of 2001, the School of Aeronautics & Astronautics was ranked fourth among undergraduate programs. With an undergraduate enrollment of nearly 6,100, graduate enrollment of about 1,300 and a faculty of approximately 270, Purdue’s engineering program is one of the largest in the U.S. It encompasses 13 schools, departments and divisions, making Purdue a leading engineering institution.

Purdue to House NASA CenterNASA announced in March

2002, that Purdue would head a center to develop “advanced life support” technologies for sustaining human colonies on Mars and elsewhere in space. Purdue has received a $10 million, five-year grant to lead the NASA Specialized Center for Research and Training for Advanced Life Support. Half of the grant will go toward researching waste management in space, 20 percent toward systems analysis and food technology and 10 percent to provide educational outreach about the program.

Purdue will help design a self-sustaining environment for future space colonies. Residents will grow their own crops and live inside fully enclosed habitats. Plants will provide food and oxygen for humans, and microbes will be

used to break down wastes; other technologies will be needed to remove impurities from the air and water. NASA’s expectation is that the life-support ecosystem will be ready, and people will be living on Mars by the end of the second decade.

The outreach component will be combined with the Indiana Space Grant Consortium based at Purdue and directed by Barrett Caldwell, an associate professor in Industrial Engineering. The Space Grant Consortium is a group of

universities and institutions that work with schoolchildren, teachers, college students, industry and museums to increase the public’s knowledge about science and space exploration.

Amelia Earhart at PurduePurdue has had a long-standing association with Amelia Earhart, and this was further enhanced on May 2, 2002. Sally Putnam Chapman, Earhart’s step-granddaughter, made a gift to Purdue of 492 of Earhart’s personal papers and memorabilia, many never seen publicly before. The gift was added to Purdue’s existing collection, previously donated in 1940 by Amelia’s husband George Palmer Putnam, and ranged from flight suits to scarves and a portrait of a model of one of her planes. The special ceremony was staged inside Hangar One in the Purdue airport in West Lafayette. The collection will be known as the “George Palmer Putnam Collection of Amelia Earhart Papers.”

Amelia Earhart became a household name in 1932 when she became the first woman—and second person—to fly solo across the Atlantic on the fifth anniversary of Charles Lindbergh’s feat, flying from Harbor Grace, Newfoundland to Londonderry, Ireland. In January 1935, Earhart became the first person to fly solo across the Pacific Ocean from Honolulu to Oakland, California.

Earhart served as a woman’s career counselor and visiting instructor at Purdue from 1935 to 1937, and her fatal flight took off from Purdue Airport. In July 1936, she took delivery of a Lockheed 10E “Electra” funded by the Purdue Research Foundation and started planning her round-the-world flight. Although this planned flight would not be the first to circle the globe, it would be the longest—29,000 miles—following an equatorial route. The first attempt in March 1937 had to be cancelled after damage during take off resulted in the plane being shipped to California for repairs. The second attempt departed from Miami on June 1, 1937. After making good progress and completing over 22,000 miles of the journey, contact was lost on July 2, 1937. The last positive position report and sighting

The William E. Boeing Distinguished LectureThe School of Aeronautics and Astronautics

was proud to host the third William E. Boeing Distinguished lecture on September 5, 2001. Our guest speaker was Dr. Jürgen Weber, Chairman and Chief Executive Officer Deutsche Lufthansa AG. Dr. Weber shared his vision of aviation in the new millennium with his presentation, “Trends Influencing Air Transport in the 21st Century.” Weber has served as CEO of Lufthansa since 1991. Under his leadership, the airline was restructured and privatized in 1997. He was also instrumental in initiating an improvement of aero-engine monitoring systems. “Jürgen Weber is a forward-thinking man whose work has won him accolades from many in the air transport industry,” said Boeing Air Traffic Management President John Hayhurst BSAE ’69, HDR ’98, who attended the lecture. “Mr. Weber’s insight and foresight will prove to be highly valuable as we develop the new paradigm of air traffic management. I look forward to partnering with Lufthansa, to improve air traffic safety, reduce delays and open the skies to increase capacity.” Weber has been internationally recognized for forming a number of airline alliances, including the Star Alliance, for which Aviation Week and Space Technology magazine presented him with the Laurels 2000 Award. Other honors include being named Manager of the Year 1999 by the German Manager Magazine for his role in Lufthansa’s privatization and his leadership in transforming the airline into an aviation group. Weber earned an aeronautical engineering degree in

1965 from Stutgardt Technical University. He joined Lufthansa’s engineering division in Hamburg in 1967. In 1980, he graduated from the senior management-training program at the Massachusetts Institute of Technology, where he specialized in business administration. Before being elected as CEO, Weber served as chief operating technical services and chief executive technical services for Lufthansa. As CEO, he is active with the Association of European Airlines and the International Air Transport Association, for which he chaired the strategy of the board of governors in 1996. Lufthansa and Boeing have a long history of successfully working together, witnessed by several airplane models that the airline has launched over the years. Purdue is the alma mater of more than 500 Boeing employees.

The Indiana Working Together for Aerospace Excellence ConferenceA new conference

was held at Purdue on April 11, 2002, that encouraged economic development by bringing together Indiana aerospace-related companies, university researchers and students. Purdue’s Schools of Engineering and School of Technology and the Indiana Aerospace Initiative sponsored the Indiana Working Together for Aerospace Excellence conference. Dr. Martin C. Jischke, president of Purdue, was the keynote speaker at the day-long conference. Nearly 250 companies in Indiana perform some type of aerospace related function, which led to the formation in December 1998 of the Indiana Aerospace Initiative (IAI). Its purpose was to help Indiana aerospace companies increase their business base. The IAI is one of three industry outreach programs sponsored by Indiana Business Modernization and Technology Corporation (BMT). By determining the needs of Indiana aerospace companies, the IAI has brought resources to the table for member companies and helped them overcome impediments to increasing their business here. The event featured talks by industry leaders and top university administrators. The panel members who discussed the topic, “Aerospace Industry and Education Come Together: Where Do We Need to Go?” included representatives from Alcoa, The Boeing Company, Rolls Royce, ITT, FedEx, United, ATA, TriAerospace LLC, and Etalon Inc. Linda P. B. Katehi, John A. Edwardson Dean of Engineering, and Dr. Fred Emshousen, Acting Dean of Technology Schools, made brief introductions to their schools and the purpose of the poster sessions presented by faculty members and students.

The primary audience for this conference included college students who would be seeking careers with high-tech companies, manufacturers and other companies, especially those seeking technological methods to improve their products. In addition to the students being exposed to various high-tech aerospace companies in Indiana, this conference also gave the opportunity to introduce various companies to the research opportunities at Purdue.

was over the Nukumanu Islands about 800 miles into the flight.

A six-week public display is expected to open in Purdue’s new Stewart Center gallery on March 10, 2003. The announcement of the new Earhart acquisitions also launched Purdue’s “Countdown to 100 Years of Flight” celebration, which acknowledges the anniversary of the Wright Brothers’ first manned powered flight and the University’s ongoing role in aviation and aerospace technology.

Digitized pieces of the collection are being placed online at www.lib.purdue.edu/aearhart/ to make the documents easily accessible to the public for the first time. An original song about Earhart was performed during the May 2 celebration of the Earhart donation. Laura Clavio wrote “Amelia Can Fly” and Julie Ricciardi performed the song accompanied by Michael Kelsey. The song can be heard online at http://news.uns.purdue.edu/UNS/html4ever020502.Earhart.song.html.

Astronaut Frank L. Culbertson Visits Campus

The School of Aeronautics and Astronautics was proud to host

Captain Frank L. Culbertson in Grissom Hall on Wednesday April 3, 2002. Speaking to a packed audience, Captain Culbertson asked who were pilots in the audience; he then used an aeronautical analogy that would stand as a model wherever you are in your career:

Aviate, navigate and communicate.

When you aviate, you trim your wings and keep your eye on the horizon; when you navigate, you check where you are and where you are going; and when you communicate you stay in touch with ground control and those around you.

He talked about his time as commander of Expedtion–3 on the International Space Station, which took place from August

12, 2001–December 15, 2001. He shared a video produced by NASA of life in the space station, and told of the wonders of space walking. On September 11, 2001, he heard about the events in New York and Washington from a ham radio operator. NASA confirmed the news. “We’re not having a real good day here on Earth,” was the start of the message from the NASA mission control center that informed the astronauts about the terrorist attacks. He photographed the World Trade Center fires as he orbited Earth and showed one of his pictures. “I saw a dark gray mass spread over lower Manhattan, and I think I saw a tower collapse,” he said. He and his crewmembers Vladimir Dezhuroz and Mikhail Tyurin joined him in a moment of silence for those who died and

raised the stars and stripes in the space station.

Culbertson knew that he wanted to be an astronaut and a Navy fighter since he was 13 years old. Because of limited space in test pilot schools, he applied four times before he was accepted. He applied to NASA twice. He entered the space program in 1984 and was one of 17 selected out of 7,000 applicants. A veteran of three space flights, Culbertson has logged over 142 days in space. STS–38 Atlantis, November 15–20, 1990, was a Department of Defense operation. “I can’t tell you what I did,” Culbertson said. “ I’d have to kill you if I did, but you’d be real proud of us if you knew.” STS–51 Discovery September 12–22, 1993, was a ten-day mission when the crew deployed the U.S. Advanced Communications Technology Satellite. The mission concluded with the first night landing of the shuttle at the Kennedy Space Station Center.

Culbertson is a huge advocate for the space program and said that when he talks to anyone in Washington, he talks about his travels. Culbertson said, “You’re going to see the space program continue. When I was younger, I expected we’d have moon bases as training grounds and I would be a candidate to go to Mars. But, that is not going to happen in my generation.” Yet he expects to see it happen, “I feel strongly that the first Martian is alive and well on Earth right now, preparing for the mission to Mars.”

The Raisbeck Engineering Distinguished Professorship for Engineering and Technology IntegrationA reception was held at Grissom

Hall on October 25, 2001, to honor Dr. Alten F. Grandt as The Raisbeck Engineering Distinguished Professor for Engineering and Technology Integration. The Purdue board of trustees ratified Grandt as the inaugural recipient of this prestigious award in December 2000.

James D. Raisbeck BSAE ’61, DEA ’79, OAE ’99 and his wife, Sherry L. Raisbeck, donated $2,000,000 to Purdue to establish The Raisbeck Engineering Distinguished Professorship for Engineering and Technology Integration. James D. Raisbeck earned his degree in aeronautical engineering at Purdue after a tour of duty in the 1950s as a mechanic and then flight engineer in the U.S. Air Force. He was a research aerodynamicist and

program manager at The Boeing Company from 1961 to 1969. He left Boeing to become president and CEO of Robertson Aircraft. In 1973, he founded the Raisbeck Group, where he developed the Supercritical Wing for the Sabreliner and the Mark II and Mark IV Systems for the Learjet 20 series. From there he started Raisbeck Engineering, where he developed and certified a number

of aerodynamic improvements for business aircraft, including the Learjet, Sabreliner, and King Air. Raisbeck Enhanced Performance Systems are installed on more than 30 percent of all King Airs worldwide.

Purdue now has 48 distinguished professors and 21 named professors. Grandt spent eight years as a materials research engineer at Wright-Patterson Air

Force Base in Dayton, Ohio, before joining the Purdue engineering faculty in 1979. He served as head of the School of Aeronautics and Astronautics from 1985–1992 and won the E.F. Bruhn Best Teacher Award in 1997. In December 2000, he was presented with the U.S. Air Force John W. Lincoln award, which is given annually to a distinguished career expert who has made significant contributions toward the advancements in flight vehicle structural integrity and safety. Grandt is highly respected in the fields of aeronautics and astronautics, applied mechanics and materials science for his work in developing methods to analyze and design damage-tolerant aerospace structures and materials. Grandt’s current research is focused on the challenge of ensuring the structural integrity of aging aircraft.

E.T. Phone HomeTwo decades after making

his first long-distance call to phone home, the alien E.T. used his odd-looking intergalactic telephone to contact the Expedition Four

crew orbiting Earth onboard the International Space Station. It’s the first alien-to-astronaut call for the creation of Academy Award-winning director Steven Spielberg

who celebrated the 20th anniversary of his film E.T., The Extra-Terrestrial on March 19, 2002, at Universal Studios in Orlando, Florida. Children from surrounding schools participated in this unique communiqué and learned about life in space from American astronauts Carl Walz and Daniel Bursch. Russian Commander Yury Onufrienko supervised the transmission from the International Space Station while NASA astronaut and Purdue alumnus Janice Voss BSES’75, answered questions on the ground. Voss was

able to show the importance of a science and mathematics education and how research in space impacts everyday life at home. Many children dream of becoming an astronaut and exploring the stars to see if life exits elsewhere. E.T. made the concept of extraterrestrial life seem like a possibility for kids around the world. This communiqué inspired a new generation of explorers by giving students the opportunity to experience firsthand the wonder of space travel.

Outstanding Engineer Award 2001The School of Aeronautics and

Astronautics was proud to host the Third Annual Outstanding Engineer Awards Banquet on November 15, 2001, at the University Inn in West Lafayette. Seven Purdue alumni shared honors for their demonstrated excellence in industry, academia, governmental service or other endeavors, which reflect the value of an aerospace engineering degree. The 2001 Outstanding Engineer Awards were presented to the following phenomenal Purdue alums.

Dr. Alon Dumanis PhD ’82 is the former Head of Materiel Directorate and Brigadier General in the Israeli Air Force (IAF). After

graduating from the Aerospace Engineering School of the Technion, Dr. Dumanis launched a two-year campaign to volunteer for service in the IAF and eventually succeeded in bending the policy prohibiting the drafting of the handicapped. He graduated with distinction from officer training. Dr. Dumanis became an expert in aircraft fatigue and was sent to the U.S. where he completed his PhD at Purdue. Upon his return to Israel he worked for four years on the development of the Lavi Fighter as the Chief Aeronautical Engineer of the Lavi System Program Office in the Ministry of Defense. When cancellation of the program became an issue

he delivered presentations to the Under-Secretary of Defense at the Pentagon and to the Israeli Minister of Defense. Before becoming the Head of the Materiel Directorate, Dr. Dumanis studied at the National Defense College where he applied modern management methods to foreign affairs and political science dilemmas. While heading the Materiel Directorate he was very successful in implementing programs for improving organizational quality

and effectiveness. Michael T.

Kennedy BSAE ’70 for the past six years was the program manager chartered with developing

Boeing’s newest Delta launch vehicles. The Delta III, configured to launch intermediate class commercial satellites, began operations in 1998. The Delta IV family of rockets, Boeing’s entry in the U.S. Air Force’s Evolved Expendable Launch Vehicle program, will begin launching commercial and government satellites in 2002. Within his 32 years at Boeing/McDonnell Douglas, Mr. Kennedy was previously in charge of developing the first American elements of the international Space Station. These began successful on-orbit assembly operations in 1998. Additionally, he led various technical teams in the design, analysis and test of space systems structures on a wide variety of missiles and

space programs dating back to Saturn and Skylab programs. Mr. Kennedy retired from Boeing in mid-2001, but continues to serve the company as a consultant on Space and Communications Group development programs and risk management processes.

Yasuhiro Kuroda MSAE ’53 served in Japan’s Army Air Force during World War II. In September 1951, he enrolled

at Purdue and studied rocket propulsion under Dr. Maurice Zucrow. In 1957, Dr. Kuroda joined Japan’s Air Self-Defense Force and was engaged in the development of guided missiles. In 1964, he was invited to work for the establishment of the U.S.– Japan Space Agreement. In 1969, he was appointed Director of Systems Planning Division of the newly formed National Space Development Agency (NASDA) of Japan. Dr. Kuroda’s most significant accomplishment at NASDA was the successful launching of Japan’s first geostationary satellite with N rocket in February 1977. Dr. Kuroda retired from NASDA in 1981 to teach thermodynamics at Kyushu Sangyo University. In 1987, he supported the Shimizu Corporation as senior advisor on a variety of space projects. He also played key roles in space consulting and education, such as president of CSP–Japan, and

trustee emeritus of International Space University.

Mary Cedars Keeps her Brother’s Dream AliveMary Cedars has given an aeronautical engineering scholarship in her brother’s memory for the past 19 years. She increased the scholarship amount to $1,000 last year, thus becoming one of Purdue’s newest President Council members.

On September 11, 1945, Mary’s brother, Air Force Flight Officer Russell Oscar Cedars, was killed when his plane was shot down over China. Mary, now aged 92, remembers her younger brother as a boy who was captivated by flight and as a young man followed his dream to become a pilot. In the fall of 1939, he enrolled in the aeronautical engineering program at Purdue. He put his education on hold in 1941 to become an instructor in the Civilian Pilot Training Program; Russell and his colleagues trained more than 500 pilots in two years.

He relocated in 1942 to Arcadia, Florida, to continue his work at a U.S. Army Training Station; he later joined the U.S. Air Force as part of the Air Transport Command, in which pilots shuttled new aircraft from the U.S. to Europe.

At the height of World War II, Russell accepted an oversees assignment to fly supplies over the Himalayas from India to western China. The official end of World War II was on September 5, 1945, but he was tragically shot down six days later at the age of 26 while flying

Mars–2001 Space OdysseyFive Purdue alumni are key

NASA mission specialists in charge of the 2001 Mars Odyssey spacecraft managed by NASA’s Jet Propulsion Laboratory in Pasadena, California. David A. Spencer BSAEE ’89, MS ’91 is Odyssey mission manager, Robert A. Mase BSAEE ’89, MS ’91 is head of navigation team, Julia L. Bell MS ’91, PhD ’95, is spacecraft-maneuver designer, Stuart R. Spath BSEE ’86 is spacecraft team chief and Peter G. Antreasian BSAEE ’84, is navigator.

A key focus of NASA’s efforts to make the Odyssey mission a success has been orbit insertion accuracy. The Odyssey navigation team flew to within 1km of the orbit insertion aim point. The mission has been under intense scrutiny by NASA as a result of back-to-back losses in 1999 of the Mars Climate Orbiter and Mars Polar Landing spacecraft.

Odyssey entered orbit around Mars on October 23, 2001, and since then the craft has been guided through a series of maneuvers to shape its orbit into a circle with an average altitude of about 250 miles above the planet’s surface. From

that height, the robotic probe’s instruments—a thermal emission imagine system and a combination gamma ray spectrometer and neutron detector—has mapped the distribution of chemicals in the top three feet or so of the Martian soil. Among the 20 elements it can detect is hydrogen, which indicates the presence of water.

Locating water is the key goal of NASA’s Mars program, which includes plans for advanced robotic rovers that will dig into the surface. Wherever there are signs of water on Mars, there could be life, or at least fossils, the signatures of past life. Maps produced by Odyssey will guide those rovers to spots that

appear rich in water today or were soaked in the past.

The 2001 Mars Odyssey team was delighted on May 28, 2002, when surprised scientists found enough water ice to fill Lake Michigan twice over, and that may only be the tip of the iceberg. Researchers with the Department of Energy’s Los Alamos National Laboratory have determined

that Mars has enough water to sustain human exploratory

missions. The Thermal Emission

Imaging System (THEMIS)

began mapping Mars from an orbit of 255 miles in mid-February

2002, taking images in

both infrared and visible light.

The instrument is expected to take as

many as 15,000 visible light images through the course

of the mission. Beginning March 27, 2002, recent images of Mars taken by THEMIS are available to the public on the Internet. A new uncalibrated image taken by the visible light camera has been posted at 10 am EST daily, Monday though Friday. The pictures can be viewed and downloaded at http://themis.asu.edu/latest.html.

“I hope the scholarship will help students further their interest in the field of aeronautical engineering,” Mary said. “In this way, Russell’s dreams for flying will be kept alive.”

Past scholarship recipients keep in touch with Mary, writing letters in honor of her brother and in appreciation of the gift that has touched their lives. In one of her favorite notes, a student wrote, “Your brother flew among the clouds, I hope to fly among the stars.”

For his outstanding

accomplishments in a career dedicated to the exploration of space, the Schools of Engineering are proud to present the Distinguished Engineering Alumnus Award to Mark K. Craig BSAE ’71. The award was presented on April 19, 2002, in a daylong series of programs and events.

Mr. Craig is acting director of Stennis Space Center, NASA’s lead center for rocket propulsion

testing and remote sensing applications. He graduated from Purdue in 1971 with a bachelor’s degree in aeronautical engineering. Mr. Craig’s NASA career began when he was a 19-year-old co-op student at the height of the Apollo program. Over the years, he has served our nation’s space program through his technical expertise, outstanding management skills, and strategic planning. Mr. Craig led negotiations that brought Europe, Japan, and Canada into the Space Station. He was the creator of NASA’s strategic enterprise concept and led President Bush’s

Space Exploration Initiative to integrate robotic and human exploration.

Mr. Craig was named the Federal Engineer of the Year Award in 1991 and received the NASA Medal for Outstanding Leadership in 1992. He was the keynote speaker in 1999 at the third United Nations Conference on the Peaceful Uses of Outer Space. Mr. Craig is a two-time recipient of the President’s Meritorious Executive Award and was named an Outstanding Aerospace Engineer by Purdue in 2000.

History-Making Navigators Win AwardPurdue graduate on navigation team

The team that made history last year by navigating a spacecraft

to a remarkably safe landing on an asteroid received a laureate prize on April 16, 2002, from Aviation Week & Space Technology. Dr. Bobby G. Williams of NASA’s Jet Propulsion Laboratory, Pasadena, California, accepted the laureate’s award for the Near Earth Asteroid Rendezvous mission navigation team at the National Air and Space Museum, Washington, D.C.

Launched on Feb. 17, 1996, the Near Earth Asteroid Rendezvous mission was the first in NASA’s Discovery Program of low-cost planetary missions. On February 12, 2001, the spacecraft was coaxed into a soft landing on the surface of asteroid Eros. “The feat

of landing on a body with only one-thousandth of Earth’s gravity was all the more remarkable given that the spacecraft was not designed to land at all,” said James Asker, Washington bureau chief for Aviation Week & Space Technology magazine.

The team included navigators from both JPL and the mission’s managing center, Johns Hopkins’ Applied Physics Laboratory, Laurel, Md. The JPL navigation team included Purdue graduate Peter J. Antreasian BSAAE ’84.

Besides landing the spacecraft, the navigation team recorded many firsts; their accomplishments were recounted in the April 29, 2002 issue of Aviation Week & Space Technology. In addition to

navigating the first spacecraft to come close to and orbit around an asteroid, the navigation team also added orbits that were not part of the original plan, once brushing by the asteroid just 2.7 kilometers (about 1.7 miles) from the surface, so that scientists could get more data about the space rock. More information on the Near Earth Asteroid Rendezvous mission is available at http://near.jhuapl.edu/.

International Space StationSince the launch of the first

International Space Station assembly mission on December 4, 1998, its ongoing construction has gone on apace. Mission STS88 (Endeavour) launched the U.S. built Node 1, called Unity. From inside Endeavour’s cabin, the crew captured the Russian-built FGB, called Zarya, with the Remote Manipulator System (RMS) and the carefully choreographed dance of the rendezvous was complete. Neither of these two modules had been linked while still on terra firma, so the astronauts had to successfully fit and function Unity and Zarya from the get-go while orbiting at about 17,500 miles per hour, 250 miles above Earth. Once they were linked, “Alpha,” the International Space Station, was ready to receive its first occupants.

The endeavor, a truly international affair, boasts the participation of Germany, France, Italy, Belgium, Switzerland, Spain, Denmark, The Netherlands, Norway, Sweden, Canada and Japan.

Construction of the ISS will take over 1900 man-hours to build, including over 160 extra vehicular activities (space walks). Organization and time management is critical when working in space, therefore practice for construction takes place in the underwater facility of the Natural Buoyancy Laboratory in NASA’s Johnson Space Center. The experience of being underwater closely duplicates the effects of weightlessness and space walking

as well as for the practice of the complex assembly duties. The astronauts are required to run through a carefully prepared script, which precisely choreographs the details and movements involved in the construction.

Many Purdue alumni have contributed to the construction of the International Space Station from software engineers to Flight Controllers and Flight Directors in the Mission Control Center. In February 2001, Mark Polansky BSAE ’78, MS ’78, was the pilot aboard STS–98, when the Destiny module was delivered and installed.

Mission STS–110 began the third and final phase of construction when the space shuttle Atlantis was launched on April 8, 2002, with Purdue alumni Jerry Ross BSME ’70, MS ’72, as mission specialist. Ross made a record seventh shuttle flight, becoming the most launched astronaut in history. He also set a new record for U.S. spacewalks. Over a period of 17 years, Ross has performed nine spacewalks totaling 58 hours, 18 minutes.

The 109th mission in the history of shuttle flights, and the 13th ISS flight, featured Atlantis gently docking with the ISS over southern China, as it delivered the Boeing built centerpiece–segment, the primary truss structure. The SO (Starboard-Zero) was the centerpiece of nine truss segments

that eventually will stretch 356 feet—the longest structure ever built in space—and will support almost an acre of solar panels and cooling radiators for future European and Japanese research laboratories. It will provide electrical power for the modules of all the International Partners and enables ISS to reach its full potential as a world-class research facility. Video cameras attached to the structure monitor assemble operations and other activities on the station. Other instruments provide the data that astronauts and ground controllers use to maintain the station’s position and orient the soar panels. Two more truss segments Port 1 (P1) and Starboard 1 (S1) are scheduled to be launched by the end of 2002.

Building a zero gravity railroad

The SO truss includes pre-installed rails for the Boeing-built mobile transporter that will accommodate Canadarm 2, the Canadian-built robotic arm which was used to remove the SO segment from the shuttle’s payload. The arm was previously attached to the Boeing-built U.S. laboratory, Destiny, and plays a major role in moving and positioning payloads from the docked space shuttle and assembling the station’s structure, including the solar arrays, radiators and experiments. The “Space Railroad” has an initial 43-foot length of track and a railcar called

the Mobile Transporter. More sections of track will be delivered during the next two years. By the end of this year the tracks will stretch more than 130 feet. The Handcars are scheduled to be launched in late summer 2002.

Purdue alumni astronaut Jerry Ross undertook testing of early designs of the handcars called the “Crew and Equipment Translator Aids” during STS–37 in 1991. The Mobile Transporter and Railway will allow the Station’s robot arm, Canadarm 2, to move almost 100 yards along the complex for maintenance and assembly. The car will have a top speed of 300 feet per hour but the entire line will be traveling at over 17,000 miles per hour. Part flatcar and part locomotive, the mobile transporter weights 1950 pounds and is made of aluminum, not iron. TRW Astro in Carpinteria, California, built the Mobile Transporter for Boeing, the prime contractor for Station construction. It measures three feet high, nine feet long and eight feet wide and moves along to parallel rails attached to the Station truss at speeds varying from 1/10 inch to 1 inch per second. Although driven by duel electric motors that generate only about 1/100 of one horsepower, the Transporter can move 23 tons of cargo down the rails. The Transporter stays on track with three sets of wheels, one set that propels it and two sets in roller suspension units, spring-loaded units that have rollers on both sides of the track to ensure the transporter can’t float loose. The

ROSS


railcar will have ten stops, specific locations called worksites where it can be locked down with a 7,000-pound grip, allowing the robotic arm to safely maneuver cargo. Although it can be driven from the Station or from the ground, the engineers for NASA’s space railroad will normally reside in Mission Control, Houston, driving the train from thousands of miles away and hundreds of miles below. Although the Mobile Transporter will be a freight train and not a passenger train, space-walking astronauts will have their own form of personal rail transportation aboard the Station. Astronauts will operate a small handcar to maneuver up and down the rail line, a car that they will pull along the zero gravity railway by hand

to move themselves and their gear from place to place. Called the Crew and Equipment Translation Aid, two such carts will be delivered to the Station before the end of the year.

Evolution of the space shuttle

More than 100 companies across the country, including Indiana, marked a significant milestone in the launch of STS–110. The space shuttle Atlantis had three new Block II Main Engines that make the world’s only reusable launch vehicle safer and more reliable than ever before. Developed in the 1970s by engineers at the Marshall Center and Boeing Rocketdyne, the Shuttle Main Engine performs at

greater temperature extremes than any mechanical system in common use today. At negative 423 degrees Fahrenheit, the liquid hydrogen fuel is second only to liquid helium as the coldest liquid on Earth. When it and the liquid oxygen are combusted, the temperature in the main combustion chamber of the engine is 6,000 degrees Fahrenheit, hotter than the boiling point of iron. This mission starts an ambitious year of station missions, delivering more than 50 tons of components by year’s end, and begins a new phase of assembly destined to enhance what already is an unprecedented facility.

Shakespeare Offers Tips for Communication Thomas Leech BSAE ’59 shares proven techniques—illustrated by the works of William

Shakespeare—in his latest book to be published by McGraw-Hill. Say it like Shakespeare: The Bard’s Timeless Tips for Successful Communications is his latest book to be published and is

less about Shakespeare than about enhancing communications in the workplace and in personal life. Each of the 24 chapters covers a different facet of communication—sending, listening, dialogue, message, motivation, team building, competition, etc.—all illustrated by writings of Shakespeare. According to the reviews, the result is an entertaining, highly readable book with relevant and applicable tips.

His first book, How to Prepare, Stage, & Deliver Winning Presentations (AMACOM, 2nd edition 1993), was honored as “one of the best business books of the year” by Library Journal. The book was a Newbridge Executive Book Club Selection and was chosen by Apple Computer for a major product promotion.

Leech is a nationally known author on public speaking, presentations and business communications. He is head of the consulting firm Thomas Leech and Associates, which he founded in 1980.

Continuing Engineering EducationThe School of Aeronautics

and Astronautics, through Purdue’s Continuing Engineering Education (CEE) program, is excited to announce that it is offering graduate level courses in aerospace engineering. The School is pleased to have this opportunity to reach students through distance education. With our history of quality education, we are confident that our School’s participation with CEE will be a benefit to all participants.

Within the current Continuing Engineering Education framework, it is possible to pursue advanced studies relevant to aerospace engineering and earn a non-thesis interdisciplinary master’s degree from Purdue without visiting the West Lafayette campus. Such study will lead to a MSE (master of science in engineering) degree if the student has an accredited undergraduate degree in engineering, or the MS (master of science) degree if the student has a degree in a related area (physics, chemistry, mathematics, etc.). A total of 30 semester hours in the non-thesis option are required for this interdisciplinary degree program.

By combining media-delivered courses with on-campus AAE courses, a student may earn a non-thesis MSE or MS degree from the School of Aeronautics and Astronautics with a limited-duration stay on campus. This combination of on-campus and remote-offered courses also provides the opportunity to earn

a thesis-option degree from the School when combined with a research project, and the potential exists to pursue doctoral studies using this combination of distance education, on-campus courses and research. Taking courses as a non-degree student to further knowledge in topics covered in one or more AAE graduate classes is also an option for off-campus students; courses taken under this status can be transferred to a degree if the grades are B or higher.

AAE 490S / 590E “Satellite Design”By Professor William A. Crossley

This course is a development of Purdue’s Center for Satellite

Engineering. The satellite design course was offered for the first time during the spring 2002 semester to senior-level undergraduates and graduate students at Purdue. This course offers students the opportunity to participate in a design study of an Earth-orbiting satellite system. Students work in teams to define the overall architecture of a spacecraft and perform the systems engineering/integration tasks. Individual students on the teams also act as systems engineers or disciplinary subsystems specialists (e.g. structures, propulsion, attitude control, etc.) taking roles like those of engineers in the satellite industry.

The student teams presented a mission definition / system requirements review in week five of the semester, a conceptual design review in week 12, and a preliminary design review during the final exam week. Each student team also prepared a written design proposal at the end of the semester.

During the spring 2002 semester, four student teams performed design studies of small satellites that could be built by Purdue students in the near future. Each student team developed a mission statement, mission objectives and system requirements for their spacecraft, and then pursued the task of defining the spacecraft system and subsystems. The four missions pursued this semester are: a technology demonstration of

a spacecraft propellant gauging system, a technology demonstration of a thruster burn profile to help alleviate velocity vector error in spin-stabilized spacecraft, an Earth-imaging satellite to provide images from orbit, and a satellite to track animals wearing transmitter collars.

To enhance the relevance of the course, and to match the classroom experience to that of the satellite industry, the reviews have included panelists from Ball Aerospace in Boulder, Colorado; The Aerospace Corporation and TRW Space and Electronics, both in El Segundo, California; NASA Goddard Space Flight Center in

Greenbelt, Maryland; and Lockheed Martin Space Systems in Palo Alto, California. These panelists participate via teleconference during the major design reviews. Both the students and off-campus review panelists

have enjoyed this interaction, and this has improved the quality of the design experience. Additionally, several engineers at these off-campus organizations have served as consultants to answer student questions via e-mail or telephone in addition to their participation as review panelists.

More information about the course, including the student teams’ design review presentations, can be found on the course Web page: http://aae.www.ecn.purdue.edu/~crossley/aae490s/Index.html.

Rocket Launch

Genetic Algorithms Naturally Select Better Satellite Orbits

Professor Steve Collicott launched a small and low-

budget student-built zero gravity fluids experiment on May 14, 2002, from the USAF White Sands Missile Range. A team of students from Fredericksburg, Texas, built the rocket. AAE junior Josh Jung is a graduate from Fredericksburg High School. Sponsored by the Center for Satellite Engineering, NASA Marshall has donated the fuel for the rocket. The Fredericksburg High School Aeroscience Program (FHSAP) formed during the ’96–’97 school year as a one-year Principles of Technology course. The original class consisted of twenty-two male students. The program has since grown, teaching as many as 120 students per year with approximately 30 percent being females. Presently, the

aeroscience program offers two years, Principles of Technology 1 and 2, and occasionally a third-year Research and Development course.

Curriculum and daily problems are presented in a manner to focus toward an annual project such as: dirigibles; remotely operated vehicles for land, water, and air; and experimental free flight sounding rockets and guided rockets. The students also learn various important aspects of universal physics such as

Newtonian physics, Bernoulli’s and Archimedes’s principles, laws of energy, etc. These help the students to understand movement and control of a self-designed research vehicle in fluid (i.e. power to weight relationships, mass properties, aerodynamics, moments of inertia, etc.).

The students are required to study the problem, teach themselves the subject relating to their problem to help understand the problem, and then develop a

designing low-cost constellations that could save money by placing a small number of satellites around the Earth at relatively low altitudes.

The algorithms adapt Darwin’s evolutionary model, interchanging design elements in thousands of combinations. Only the best-performing combinations are permitted to “survive” and those combinations “reproduce” further progressively yielding better results. The most profound impact

proposal to answer their problem; this usually comes in the form of a mathematical computation. The student’s calculations are then reviewed by at least two professionals working in the field to which their calculations relate. Once the calculations are approved, the students begin to design a component that includes drawings for future fabrication as well as personally speaking to the company that is going to produce the item. The students must also remain in the given budget. If everyone does his part, the final result is something that would have taken years for one person to produce. This program does not only teach aeroscience, but also how to speak to and work with other people, a skill that will be used by all students.

of such algorithms is that they sometimes find solutions that researchers would ordinarily have missed. An added bonus is that they run continuously, overnight and for days at a time, sorting through design options more numerous than would have been humanly possible.

The version of the genetic algorithm developed by Crossley and former graduate student Edwin Williams has culminated

in a design that minimizes satellite “blackout” times, when they cannot communicate with the ground. Such low-altitude constellations could be a boon to mobile computing by making it easier to use wireless communications devices. The constellations also may have military applications because they make it possible to quickly reposition satellite constellations for specific surveillance purposes. Research

collaborators at The Aerospace Corporation in El Segundo, California, are currently using the approach to investigate other possible constellation designs. Williams, who earned his master of science degree in December 1999, currently works for The Pratt & Whitney Division of United Technologies Corp., in East Hartford, Connecticut.

Project SEABASSSearching Europa for Aquatic Bacteria And other Subsurface Sea Life

Seniors undertake the AAE 450 spacecraft design course during

a single semester. The students perform a feasibility study for a specified mission goal subject to certain constraints. During the spring of 2002, the entire class worked as a single team and designed a complex mission to send a spacecraft to Jupiter’s second moon Europa. They had to land a probe on the icy surface, burrow into the ice and insert a robotic probe below its surface to search for any type of liquid and send back results.

Named Project SEABASS, Professor James Longuski’s AAE 450 final design presentation took place on April 18, 2002, where the students delivered a formal three-hour presentation of their results, followed by a poster session to provide further details of individual work.

Galileo Galilei discovered Europa on January 7, 1610; it is the smallest of the four major moons of Jupiter and up to 96 percent may be liquid. Its crust consists of 100km of water, originally believed to be in ice form. Data from the Galileo mission indicates that as little as 4km of the crust is ice, leaving a very deep ocean of liquid underneath.

The Mission Directive was to design a minimum cost lander/subsurface probe that would take 10 years or fewer from launch to final transmission of scientific data; place a probe in the subsurface ocean below 4k of water ice; perform a one-month investigation, both above and below the surface

in search of life; and provide a continuous live data stream 50 percent of the time and have 95 percent probability of success. The spacecraft would be in three sections, the orbiter, the lander and the Autonomous Underwater vehicle (AUV) that would be able to drill through the ice. Fiber optic cable would be used to carry information on its discoveries.

The best- and worst-case scenarios for launch dates would be September 6, 2018, and September 16, 2018, respectively. Using gravity assists, the arrival dates would be January 19, 2025, and June 2, 2025, respectively. These dates were calculated using the computer program STOUR (pronounced esstour), which is a program originally developed by NASA’s Jet Propulsion Lababotory but then improved by Professor James Longuski and his students to make it hundreds of times more powerful.

Each team member was responsible for a specific job and was organized into specialized groups to study different aspects of the mission. They detailed everything from propulsion systems and communications equipment to “slingshot” trajectories and the design of the machine needed to bore through

the ice. The orbiter structure would be constructed from aluminum and would be of standard uniform thickness. An internal temperature would be maintained at 56 degrees Fahrenheit. During the flyby of Venus, the temperature would rise in excess of 450 degrees; approaching Europa would then lead to a decrease in temperature. It would be therefore covered in silvered Teflon and have multi-layer insulation. The dish would be folded and pointed away from Venus during the flyby.

Although the unmanned mission was plotted entirely on paper, the results were based on sound scientific principles and relied wholly on current real-world technology.

The team members were: Pooja Agrawal, Amanda Allen, Angela Beaver, Greg Bischoff, Evan Brooks, James Burkett, Rico, Ebetino, Tom Fosness, Timothy Founds, John Gowan, Jeremy Hemler, Nathan Huber, Masaki Kakoi, Allison Lambeth, John Merchant, Lauren Naessens, Amanda Newenhouse, Jerry Niemczura, Michael Perotti, Paul Precoda, Jesus Villamarin.

Study Abroad OpportunitiesPurdue’s Study Abroad Office currently offers more than 200 programs in over 40 countries around the world. The School of Aeronautics and Astronautics has student exchange agreements with Bristol University, U.K.; Royal Melbourne Institute of Technology in Melbourne, Australia; University of New South Wales in Sydney, Australia; Ecole Superieure des Techniques Aeronautiques et de Construction Automobile (ESTACA) in Paris, France and Osaka University in Japan.

AAE students who have recently taken the opportunity of this experience are Yen Yu and James Pinyard at Bristol University U.K. and Masaki Kakoi at ESTACA, France. Visitors to campus include Willie Marmuse and Franck Guilbert from ESTACA, Angie Dickenson and Matthew Wysel from UNSW, Australia.

EUROPA’S ICY SURFACE


Weightlessness: What an awesome experience!By Jayleen Guttromson, Vomit Comet flight team member

Professor Steven Collicott’s AAE 490 or the Freshman

Honors 199 class truly provides an ‘out-of-this-world opportunity’ through Purdue in collaboration with NASA Johnson Space Center. During my second semester as a freshman, the chance to experience weightlessness seemed like a lot of fun, later did I really realize all of the hard work needed to test an experiment in micro gravity (μG).

Under Dr. Collicott’s leadership, we formed two teams: an ‘aero’ comprising juniors and seniors and an ‘honors’ team of six freshman. Members of the freshman team, who are now classified as juniors, included: Sarah Martin, biology; Jackie Callihan, biomedical engineering; Laura Pajot, mechanical engineering; and aerospace engineers, Jayleen Guttromson, Robert Manning, and Jeremy Mikkelsen.

We began brainstorming for experiments dealing with theories of fluid dynamics in μG. Dr. Collicott aided the freshman team by providing a published article, “Fluid Interface Phenomena in Low-Gravity Environment: Recent Results from Drop Tower Experimentation,” by M. M. Weislogel. It provided the

background and a foundation for our experiment, placing the reality of fluid μG research into a hands-on educational opportunity. With NASA deadlines soon approaching, the two teams began writing the long documented proposals, covering the experiment theory, test procedures, and outreach possibilities. The initial stage of this project was now in NASA’s judging hands. Our experiment examines capillary dominated fluid dynamics in the reduced gravity environment onboard the KC–135. In particular, we wanted to measure the behavior of the lower portion of the meniscus in the triangular tank geometries. By focusing on this portion and using longer periods of reduced gravity, the experiment may confirm that a stationary

point exists on the fluid surface in weightlessness, expanding upon Weislogel’s theory and mathematical models. Knowing this, it will enable better propellant management device designs, especially for satellite propellant refueling and gas ventilation, and for biological and material processing systems.

While building our frame, we used a different type of material than previous years, allowing for re-use of pieces and connecting ease. As some members worked on the frame, others worked on producing the experimental tanks, taking pieces of acrylic from block shape and transforming them into seven clear acrylic tanks constructed to view seven angles of four triangle geometries. The day finally came when the team leaders obtained an e-mail saying we were selected. Then reality hit; we had an experiment to finish before the beginning of summer, another technical proposal to write, and outreach obligations.

The second paper dealt with technicalities from our proposal

unclear to NASA officials and any design changes since the original. During the summer we also learned of another issue from NASA, our design needed to include a double containment system to protect fluid leakage of the tanks. Members on campus worked with the machinists to design a container that would allow us to exchange the tanks while in-flight, and still be leak proof.

On our first official day in Houston, we arrived at NASA’s Ellington Field for the Reduced Gravity Program’s Welcoming Ceremony and to de-crate our experiment. We interacted with the other schools during our session, learning about their experiments and explaining ours to them. That evening, Boeing sponsored a dinner. The next day involved setting up our experiment for the Test Readiness Review (TRR) on Monday by NASA engineers, mechanics, and scientists. The Flight crew and alternate fliers went through hypoxia training. Saturday afternoon we participated in NASA’s Open House day, taking tours on site and learning of the different opportunities in space exploration.

Monday consisted of prepping and completing the TRR with NASA officials. During the afternoon, we were able to witness a Welcome Home Celebration for the Expedition 2 crew return and had a special dinner with Purdue alumni.

After a rain delay we were able to complete the parabolas. We

Sigma Gamma Tau Outstanding Senior Award

Clare Boothe Luce FellowshipsCongratulations

to AAE doctoral student Belinda Marchand, who has been awarded one of the Clare Booth Luce (CBL) Graduate Fellowships for Women in Science and Engineering for 2002. This very prestigious fellowship was won after very keen competition and is activated in August 2002 for a two-year period of support. In addition to an annual stipend, it also provides development, equipment and program support. “The biggest impact that this award will have was the knowledge that I came out on top of an outstanding group of students,” said Belinda. “Being among such great minds was an honor in itself, but being selected

from that group… that I have no words to describe.”

Marchand, of Chicago, is a doctoral student under Kathleen C. Howell in the School of Aeronautics and Astronautics. Her research focuses on the dynamical evolution of natural bodies, such as comets and asteroids in the solar system, and the design of interplanetary spacecraft missions. Marchand is a member of the Jet Propulsion Laboratory’s Genesis mission design team and plans to continue her association with the team throughout her doctoral studies. She is a recipient of a Magoon Teaching Award and the Purdue Graduate Student Award for outstanding teaching.

The Clare Boothe Luce Program promotes the advancement of American women through higher education

in the sciences, engineering and mathematics. The Henry Luce Foundation administers the program in three categories: undergraduate scholarships, graduate scholarships and term support for tenure-track professorship level. Purdue has been awarded two two-year graduate fellowships, one in science and one in engineering.

All CBL Fellowship Finalists and Awardees were recognized for their accomplishments at a reception on April 4, 2002. Purdue President Martin C. Jischke and Vice Provost Margaret Rowe both addressed the gathering. The Clare Boothe Luce Program stands alone as the single most significant source of private support for women in science, engineering and mathematics. Clare Boothe Luce (1903–1987)

was the widow of Henry R. Luce. She was a playwright, editor, war correspondent, journalist, U.S. ambassador to Italy, and the first woman elected to Congress from Connecticut. She was a true visionary and decades ahead of her time. During the 1930s and 1940s, she broke many long-standing professional barriers and went on to be celebrated as a pioneer for the modern working women. Thus far, the program has supported scholarships and fellowships for more than 700 undergraduate and 350 graduate students. There have been 110 Clare Boothe Luce professorships.

The Raisbeck Design Build Test Program

Dan Javorsek

Design/Build/Test projects are being integrated into

the School of Aeronautics and Astronautics curriculum providing students with real-world engineering experience. Students work on the projects with their peers to develop, build, and test a design within the constraints of time and budget, including the development of theoretical ideas into practical applications. Multidisciplinary teams combine students with a wide range of background experiences in the core disciplines of aerodynamics,

controls and dynamics, propulsion, and structures. Projects range from micro gravity research experiments and rocket engines to radio controlled aircraft and racecar modifications.

To balance theoretical and practical knowledge, teams often collaborate with students from the School of Aviation Technology. Employers view multidisciplinary team experiences as a valuable asset, enhancing the knowledge gained in the traditional undergraduate curriculum.

Purdue officials believe that no one has finished a PhD

faster than Dan Javorsek. Javorsek graduated in August 2001 with a doctorate in physics. He finished his degree in two years even though his bachelor’s degree was in aeronautical and astronautical engineering. Javorsek attended Purdue as an undergraduate on an Air Force ROTC scholarship majoring in aeronautics and astronautics. His goal is to become an astronaut. When told there would be a 14-month delay in beginning his advanced pilot training after graduation in 1999, he decided to ask for a waiver so he could pursue an advanced degree. The Air Force guaranteed him a place in fighter pilot school and he guaranteed the government that he would have his PhD in hand before

he climbed into the cockpit of an F–15.

Jarorsek wanted to pursue a PhD in physics, which wasn’t his undergraduate major, meaning he would have to study basic physics texts on his own. The Air Force gave him only two years to complete his studies, including the dissertation.

Javorsek taught himself basic physics while pursing his PhD and during this time he also wrote seven research papers that were published in well-respected physics journals. His 400-page thesis was about twice the average length, and his research findings were published

obtained our first set of data and the experiment seemed to work smoothly, plus our team members didn’t get sick. After the flight we attended a lecture by NASA’s chief scientist, learning more about current and planned NASA research.

Both Purdue teams finished the 32 parabolas, one Martian and one lunar, without living up to the plane’s name, and one member from each team got to fly in the cockpit’s jump seats during the landing on the second day of testing.

Overall, the adventure is one to remember for a lifetime, for very few are able to experience the KC–135 and to test an experiment on board. We all are thankful to Professor Collicott for his determination to provide students the opportunity to apply knowledge in the classroom, Jason Helms for answering our questions and staying awake with us, and to our classmates, who helped make this experience possible during the good and bad times.

The classes below contain Design/Build/Test projects on a regular basis.AAE 439 – Rocket Propulsion

AAE 451 – Aircraft Design

in Physical Review Letters, one of the world’s most prestigious physics journals.

After graduation, Javorsek reported to Sheppard Air Force Base in Texas, where he is participating in the Euro-Nato joint jet pilot training program. He was one of 44 Americans chosen out of about 800 applicants. Javorsek will learn to fly fighter jets and has his sights set on becoming an astronaut.

Fall Space Day 2001VIP Guest Astronaut—Colonel Loren J. Shriver

“The Best Way to Predict the Future is to Create It.”

Two hundred fifty-one students in grades 3–8 registered for the

sixth annual Fall Space Day, which was held on November 10, 2001. The students of Purdue’s School of Aeronautics and Astronautics and members of the Students for the Exploration and Development of Space (SEDS) and American Institute of Aeronautics and Astronautics (AIAA) planned a well-run event that resulted in a fun-packed day of hands-on activities.

The highlight is always our Purdue alumnus astronaut; this year it was Colonel Loren Shriver who received his master’s degree in astronautical engineering from Purdue in 1968. He is a veteran of three space flights for NASA and has more than 386 hours in space. He now serves as a deputy program manager of operations for the space shuttle program of United Space Alliance. A private corporation, United Space Alliance is the prime contractor for NASA’s space shuttle program.

The opening remarks and introduction by Purdue President Martin C. Jischke were held in the Class of 1950 Lecture Hall. Shriver shared a video entitled, “Space Shuttle and Space Station Construction—Update,” which showed the construction of the International Space Station. He then took questions from the audience.

The grade school students were divided by age into twelve groups, each named after a Purdue alumnus astronaut, with volunteers from the student chapters of SEDS and AIAA to lead the groups and interactive activity sessions. Children learned that “The Best Way to Predict the Future is to Create It,” by investigating opportunities for a Mission to Mars

exploration. The activity sessions included: Mars Rockets, Edible Mars Habitat, Rover Construction Lab, Satellite Launch,

“Space Travel” Spring Break! By John Matlik

This spring brought a unique opportunity for educational outreach to a younger audience. The School of Aeronautics and Astronautics provided a guest lecturer and companion on-campus lab tour as a part of a spring break “Space Travel” program for the Community Family Resource Center of West Lafayette, Indiana. Activities were planned at each laboratory location with emphasis on visual, hands-on learning activities or experiments aimed at feeding the dreams of future aeronautical and astronautical engineers. Paper airplanes were constructed, rocket planes were launched, and soda cans were crushed. The kindergarten through fifth grade audience had an opportunity to learn about the Purdue / NASA “Zero G” experiments on the Vomit Comet, what happens when a rocket nozzle isn’t designed correctly, and details of the International Space Station. In short, this event provided the exciting opportunity for graduate students to share their dreams of space with the astronauts of tomorrow.

Lab tour locations: Fretting Fatigue Lab (structures), Undergraduate Design Lab (Aerodynamics), Dynamics Lab (Dynamics), and WTHR 104 (Propulsion)

Helpers: Brian Ventre (guest lecturer), Govindarajan Kothandaraman, Murthy Haradanahalli, Stephanie Marie Van Y, Shin Matsumura, Robert Manning, Andrew Remson, Yu Matsutomi, Luis Pedro D’Alto, John Matlik, Dr. Marc Williams

Descent Stage Lab, and Mars Rover Control Operations. Shriver visited all the activities and had a chance to talk to the elementary school students, their parents and teachers.

In addition to attending Fall Space Day, Shriver also visited a local elementary school and gave a public presentation on the evening before Fall Space Day to a packed audience in the Stewart Center on campus. Shriver said that even if none of this year’s participants in Fall Space Day become astronauts, they might find other ways to serve the space program. “There’s more opportunity besides being an astronaut—engineers, scientists, economics, business—all are integral parts of any successful program,” Shriver said. An Iowa farm boy, Shriver said that he never had such learning opportunities as a youth.

United Technologies Corporation, Indiana Space Grant Consortium, Purdue Students of the Exploration and Development of Space (SEDS) and the American Institute of Aeronautics and Astronautics (AIAA) campus student chapter sponsored Fall Space Day 2001.

The 186th commencement at Purdue took place on the weekend of May 10–12. The Schools of

Tech BriefsAAE graduate Angela K.

Beaver BSSAE ’02 together with colleague Donald S. Greer of the Dryden Flight Research Center, Edwards, California, have published an article in the prestigious Tech Briefs, a NASA sponsored publication.

“Study of Turbulent Boundary Layer on the F–15B Airplane” was published in March 2002 and can be accessed at www.nasatech.com. It explains that the study of turbulent boundary layer on an aircraft surface in flight has not been perfected due

to the limitations in the use of conventional anemometry systems. Wind tunnel experiments are significantly different from flight experiments because of the length scale characteristic of turbulence in the wind tunnels. Computational fluid dynamics computer codes require validation in order to predict transitions from laminar, or smooth, flow to turbulent flow.

Recent developments in automated hot-wire anemometry system is offering a bridge between theory and practice.

NASA’s F–15B, a two-seater version of the F–15 high performance, supersonic, all weather fighter airplanes, is a flying test bed for a wide variety of flight experiments. This airplane was fitted with a constant voltage aerometry (CVA) system in a space on the aircraft frame with known aerodynamic conditions.

The CVA system took measurements from retractable probes mounted at 45 degrees to the surface extending known distances above the aircraft skin. Data was collected under various

flight conditions ranging from 0.6 to 1.3 mach at altitude between 15,000 and 30,000 feet. This data is currently being analyzed but extracts show that there is significant turbulence at 1, 2 and 3 centimeters from the skin. Turbulence is considerably lower at 4 centimeters, indicating the edge of the boundary layer.

Engineering held their ceremony in the Elliot Hall of Music on Friday May 10 at 8:00 p.m. Earlier in the day the Schools of Engineering held an “Engineering Send Off” in the Memorial Mall with all 13 Schools represented. During the ceremonies, approximately 5,200 students, 4,277 of whom are undergraduates, received degrees. In his speech, Purdue President Martin C. Jischke emphasized to the student body an obligation to fulfill their destiny and give back to their community.

Congratulations to the graduates from the School of Aeronautics and Astronautics.

Aero Advancementby Tim Bobillo

Writing this column is

a pleasure for me because it gives me another chance to do the thing that I enjoy most about my position as director of development for the School—I get to thank the alumni and friends who contributed to the success of AAE in 2001–2002. This year, for the first time, the number of donors to the School exceeded 1,000. The gifts supported scholarships, faculty initiatives, research, laboratories and day-to-day operating expenses. Each contribution provided important opportunities for students, faculty and staff. So, to all who partnered with us, THANK YOU!

Four extraordinary gifts deserve special recognition.

John Rich gave $50,000 toward the John and Patricia Rich Scholarship that he established in 1999. John has contributed $150,000 toward this endowment and pledged an additional $100,000. In order to attract the very brightest young minds to study aerospace engineering, it is increasingly important to have resources like this scholarship.

The Arthur Remson Memorial Scholarship was established through a gift of $25,000 from Linda and Andrew Remson (BSAAE ’01, MSAAE ’02), widow and son of the late Arthur Remson. Arthur was very proud to know that his son was studying aeronautical engineering at Purdue, but passed

away before his son graduated. In Arthur’s honor, the scholarship was established for students from a family in which an immediate member has served or is serving in an active duty capacity with the U.S. military.

Anne E. Belfort added to the Dr. Anne D. Belfort Fund in Astronautics with a gift of $22,700. This fund supports curriculum development in our increasing number of astronautics courses.

Lloyd and Rosie Hackman continued their generous support of the School with a gift of $20,215. This gift was the result of a maturing trust that Lloyd had previously established with the University.

The coming year will be one of advancement and growth for the School. Our plans for a new home for AAE are developing quickly.

Donor Honor Roll2001–2002

With the assistance of our alumni and friends, and our partnering with the State of Indiana, we can raise the funds to build the Multidisciplinary Engineering Building. This new facility will greatly enhance how our faculty interacts with our students and how our students learn; it will be a complete learning center with spaces unlike those we have available today. With your support, we will build a space that will give Purdue an advantage in engineering education and research.

Thank you, again, for your support, financial and otherwise. I hope you remain connected to our School. Our reputation was formed through your success, and you are part of our success. We want that excellence to continue.

Our annual Donor Honor Roll lists our alumni and friends

who have given generously of their financial resources to support the School of Aeronautics and Astronautics.

Many thanks for your investment in us. Listed on the following pages are those alumni and friends who have generously donated to the School during the period July 1, 2001–June 30, 2002.
