Glenn CurtissGlenn CurtissGlenn CurtissGlenn Curtiss
Thomas Baldwin was looking for a lightweight engine for his dirigible
He saw how well Curtiss’s bike engine performed and asked if he could buy one
Curtiss agreed and tweaked one of his engines for use in an aircraft
Baldwin’s aircraft, with a Curtiss engine, was the first powered dirigible in America

Curtiss joined the Aerial Experiment Association
Alexander Graham Bell—best known as inventor of the telephone—formed this group
The group made some important design breakthroughs
First, they built the first American plane equipped with ailerons

Ailerons Ailerons Ailerons Ailerons
An aileron aileron is a small flap on the wing for controlling turns
Ailerons replaced the Wright brothers’ wing-warping technique
The aileron was a more effective means to move an aircraft left or right
It also provided lateral balance The association introduced ailerons to
America but the idea originated in England

Louis BlériotLouis BlériotLouis BlériotLouis Blériot
French pilot Louis Blériot was the first man to cross the English Channel in a heavier-than-air craft
Although Blériot encountered problems—he got lost and his engine overheated—he managed to land safely
The flight took 37 minutes

Names and Anatomy of Names and Anatomy of Period AircraftPeriod Aircraft
Names and Anatomy of Names and Anatomy of Period AircraftPeriod Aircraft
Frenchman Robert Esnault-Pelterie was the first to fully enclose the fuselage and use ailerons
A fuselagefuselage is the body of an airplane containing the crew and passengers (or cargo)
Enclosed cabins protected pilots and passengers from the wind and rain
Chapter 2, Lesson 2
Multiengine PlanesMultiengine PlanesMultiengine PlanesMultiengine Planes
English brothers Eustace, Howard, and Oswald Short experimented with adding engines to their aircraft
A multiengine planemultiengine plane is a plane with more than one engine
Two (or more) engines upped an aircraft’s power, reliability, and safety
Chapter 2, Lesson 2
The The Triple TwinTriple TwinThe The Triple TwinTriple Twin
The Short brothers built the Triple Twin, a two-engine, three-propeller aircraft, in 1911
They placed one engine in front of the cockpitcockpit—a space inside the fuselage where the crew sits
They mounted the second engine behind the cockpit
Chapter 2, Lesson 2
Le GrandLe GrandLe GrandLe Grand
Russian pilot Igor Sikorsky designed a four-engine aircraft called Le Grand
He flew it on 13 May 1913
He used four 100-horsepower engines to lift the 92-foot-wingspan airplane

Chapter 2, Lesson 2
Rotary EnginesRotary EnginesRotary EnginesRotary Engines
The earliest engines were relatively heavy and inefficient
One reason was that these early engines used water as a coolant
Brothers Laurent and Gustav Seguin of France set out to reduce the motor weight
Their solution? Rotary engines
Chapter 2, Lesson 2
Rotary EnginesRotary EnginesRotary EnginesRotary Engines
Rotary engines used circulating air, rather than water, as a coolant
The Seguins placed the engine’s cylinders in a radialradial, or round, pattern
They fitted each cylinder with a fin to draw out the heat as the plane flew
With these changes, engines became more efficient and their weight dropped

HelicoptersHelicoptersHelicoptersHelicopters
Helicopters are different from other aircraft in two important ways:
First, they don’t have fixed wings—they have rotating wings
Second, they take off and land vertically

Chapter 2, Lesson 2
HelicoptersHelicoptersHelicoptersHelicopters
The wings of helicopters, like those of other aircraft, must be in constant motion
Helicopters have rotorsrotors—another name for propellers
Rotors are made up of blades, each of which acts as a wing, and as the blades rotate, they lift the helicopter
Helicopters are also known as rotary-wing aircraft

Manned HelicoptersManned HelicoptersManned HelicoptersManned Helicopters
In 1842 W. H. Phillips got a model helicopter with a steam engine into the air
In 1907 Frenchman Louis Bréguet flew one, as did his countryman Paul Cornu
In 1909 Americans Emile and Henry Berliner also built and piloted a helicopter
All these men faced one common problem: helicopters are difficult to balance
No one would find a solution for 30 years

American Aviation PioneersAmerican Aviation PioneersAmerican Aviation PioneersAmerican Aviation Pioneers
While some aircraft pioneers were achieving fame as inventors, others were breaking barriers as pilots
Those barriers ranged from distance to altitude to gender and race
The early 20th century was a time when all kinds of records could be broken

The The Vin Fiz FlyerVin Fiz FlyerThe The Vin Fiz FlyerVin Fiz Flyer
Could Calbraith Perry Rodgers fly across the United States in 30 days? That was his goal in 1911
Newspaper publisher William Randolph Hearst was offering a $50,000 prize
Rodgers asked soft drink manufacturer Vin Fiz if it would provide financial support for his flight in exchange for nationwide publicity
Chapter 2, Lesson 2
The The Vin Fiz FlyerVin Fiz FlyerThe The Vin Fiz FlyerVin Fiz Flyer
Rodgers took off on 17 September 1911 from Sheepshead Bay on New York’s Long Island
The plane needed countless repairs and made many stops along the way
It took 49 days—Rodgers didn’t win the award because the flight took too long—but he made history
Chapter 2, Lesson 2

PFC Vernon Burge was the first enlisted man to become a pilot
The US Army Signal Corps’ Aeronautical Division had a general rule that only officers could be pilots
Enlisted men trained as mechanics Burge was one of eight enlisted men
who joined the division in 1907
Chapter 2, Lesson 2

Burge helped build a landing system for 1st Lt Benjamin Foulois’ airplane
During this time, Burge learned as much as he could about airplanes
He became a pilot in 1912 It wasn’t until 18 July 1914 that the US
House of Representatives passed a bill that authorized enlisted men to fly
It also gave official status to the Army’s aviation arm
Chapter 2, Lesson 2
Bessie ColemanBessie ColemanBessie ColemanBessie Coleman
Bessie Coleman faced two obstacles to becoming a pilot—her race and her gender; she overcame both
In 1921 Coleman became the first black woman to get a pilot’s license
She had to go to France for training because no flight school in the United States would accept her
She died in an airplane crash only four years after getting her license
Chapter 2, Lesson 2
Blanche Stuart ScottBlanche Stuart ScottBlanche Stuart ScottBlanche Stuart Scott
Scott was Glenn Curtiss’s only female student in 1910
Curtiss worried about this—if Scott crashed, he feared he’d be blamed for putting a woman in harm’s way
So Curtiss did what he could to keep Scott from being able to take off
Chapter 2, Lesson 2
Blanche Stuart ScottBlanche Stuart ScottBlanche Stuart ScottBlanche Stuart Scott
Nonetheless, Scott managed to fly one of Curtiss’s planes one day
Scott had become the first American woman to solo in a fixed-wing airplane

Bessica Medlar Raiche Bessica Medlar Raiche Bessica Medlar Raiche Bessica Medlar Raiche
Some aviation historians think Bessica Medlar Raiche was really the first woman to go solo
She made that flight on 13 October 1910 Raiche never got a license, but flying
excited her She and her husband, François, formed a
lightweight airplane company called the French-American Aeroplane Company
Chapter 2, Lesson 2
Harriet QuimbyHarriet QuimbyHarriet QuimbyHarriet Quimby
In 1911, Quimby became the first American woman to earn her pilot’s license
She was also the first woman to fly at night (1911) and to pilot across the English Channel (1912)
She broke a fashion barrier, too, by designing and wearing a jumpsuit

Chapter 2, Lesson 2
Harriet QuimbyHarriet QuimbyHarriet QuimbyHarriet Quimby
Quimby entered the Boston Air Meet in 1912 She and her passenger took off over Boston
Harbor in hopes of making a record 58 mph flight over a body of water
At 5,000 feet, the plane flipped and nosed downward
Quimby and Willard fell from the plane and plunged into the waters—both perished
Chapter 2, Lesson 2
Matilde MoisantMatilde MoisantMatilde MoisantMatilde Moisant
On 13 April 1911, Moisant became the second woman in America to get a pilot’s license
She won the Rodman Wanamaker Trophy for flying at an attitude of 2,500 feet
She also a court to acknowledge it was legal to fly on Sundays
Her brother John Moisant, also a pilot, had died in a crash in 1910
His death deeply affected her and on 13 April 1912, she said she’d make her last flight the next day
Chapter 2, Lesson 2
Julia ClarkJulia ClarkJulia ClarkJulia Clark
On 19 May 1912, Julia Clark was the third American woman to gain her pilot’s license
Sadly, she was also the first woman pilot to die in a crash
She learned to fly at the Curtiss Flying School at North Island in San Diego
After soloing in a Curtiss plane, she joined an exhibition group
She took a text flight on 17 June 1912; she hit a tree limb, crashed, and died
Chapter 2, Lesson 2
Katherine and Marjorie Katherine and Marjorie StinsonStinson

Katherine Stinson earned her pilot’s license on 24 July 1912
She was the fourth American woman to do so, and at age 16, she was also the youngest
She would eventually become one of the most successful women in aviation
Her younger sister, Marjorie, graduated from the Wright Flying School in August 1914
When WWI began, the sisters opened a school to train Americans and Canadians as pilots for the war
