Aviation Before World War 1
1903-1914
1900-Count Ferdinand von Zeppelin- used an engine to fly balloons Airship or Dirigible
Also known as ‘dirigible’ which means controllable.
Ferdinand Adolf August Heinrich Graf von Zeppelin (1838-1917).
Count Ferdinand von Zeppelin was the inventor of the rigid airship, or dirigible balloon.
Ferdinand von Zeppelin spent nearly a decade developing the dirigible.
The first of many rigid dirigibles, called zeppelins in his honor, was completed in 1900.

Forward Momentum
How Airship Works Upward motion is based on the principle of
Archimedes. When airship rises, density of air inside the
airship decreases. When up thrust equal to weight of airship,
airship will float in atmosphere. Descend of airship is controlled by the
release of Helium gas inside it. Direction of the airship is not dependent on
the wind but it’s direction was controlled by rudder.
1st commercial air service
In 1910, a zeppelin provided the first commercial air service for passengers.
It provided air service between Europe and America in the 1920s and 1930s
One such airship was 3 times larger than a Boeing 747 and cruised at 68 mph.
Balloons Application
US first used airship for military purposes during the Civil War.
After the war ended, the military service change to transportation, shooting off fireworks and aerobatic shows.
Until World War 1 (1914) more than 1,780 airship had safely carried 27,700 passenger.
Destruction of zeppelin’s airshipThe zeppelin’s airship named
“Hindenburg” explodes, May 6, 1937 at Lakehurst Naval Air Station.
The Hindenburg marked the end of large scale Zeppelin travel.
Critical Thinking
WHY AIRSHIP CANNOT BECOME AN AIRLINER ?
The Disadvantages of Airship It is impossible to construct balloons of
sufficient strength. Thus, balloons unable to withstand routine
operation under all weather conditions. Critical challenge to maintain the shape of gas
bags. If the bags were only partially filled, the balloons hang down loosely.
Extremely difficult to control. Can be hazardous during landing in high winds. The large Hindenburg was equally successful until it
was destroyed by fire while attempting a landing in 1937 in Lakehurst, New Jersey.
Aviation Before WW 1: 1903-1914 1903: The Wright Brothers make history as the
first to fly a powered aircraft. 1906: Brazilian-born Alberto Santos-Dumont
makes the first successful European airplane flight. His plane, the 14bis, flies a distance of about 200 feet in Paris.
1908: In a field near Paris, Henry Farman becomes the first to officially fly a one-kilometer circular course, the world‘s longest distance at the time.
1908: Piloting his plane, the June Bug, Glenn Curtiss wins a silver trophy and national acclaim for becoming the first American to officially fly a distance over one kilometer. Glenn Curtiss also known as Father of Naval Aviation
Aviation Before WW 1: 1903-1914 1909: After several failed attempts, French aviator
Louis Blériot becomes the first to fly across the English Channel. Flying his Blériot XI, he covers the 23-mile distance in 37 minutes.
1912: Harriet Quimby becomes the first woman to fly across the English Channel.
1906: Santos-Dumont makes the first successful European airplane flight.
14-bis, the plane in which Santos-Dumont made his historic 1907 flight. His plane flies
a distance of about 200 feet in Paris.
1908: Piloting his plane, the “June Bug”, Glenn Curtiss was first American to fly a distance over one kilometer.
Glenn Curtiss – Father of Naval Aviation
Curtiss was responsible for the first aircraft to take off from and land on the decks of ships at sea.
Curtiss' motives in developing the seaplane was to sell airplanes to the U.S. Navy.
It took 37 minutes for him to fly across the English Channel in 1909.
1909: Louis Blériot becomes the first to fly across the English Channel.
1909: Monoplanes Era Monoplanes developed and used for
relatively short-distance flights.
1914: 1st scheduled air service in Florida 1st scheduled air service was
seaplane.
Types of Airplane A monoplane is an aircraft with one main set of
wing surfaces. Since the late 1930s it has been the "ordinary" form for a fixed wing aircraft.
A biplane is a fixed-wing aircraft with two main wings. The Wright brothers' Wright Flyer used a biplane design, as did most aircraft in the early years of aviation.
A triplane is a fixed-wing aircraft equipped with three sets of wings, each roughly the same size and mounted one above the other. The best-known triplane is Fokker Dr.I during WW1.
Types of Airplane
A seaplane is a fixed-wing aircraft which can only take off and landing on water.
An amphibian is an aircraft that can take off and land on either land or water.
WORLD WAR 11914-1918 (4yrs)
WW1: The Era of Military Aircraft Aircraft use for military . Increased demand for military aircrafts,
more powerful motors and larger aircrafts were developed.
Aerodynamic fuselage design; monoplane, biplane and triplane designs are all considered viable aircraft.
WW 1 Era is the Key Developments World War 1 saw the rise of the aircraft as
a weapon system and the changing face of war.
The aircraft changed the modern battlefield
De Havilland DH-4 biplane, a British-designed two-seater bomber mass-
produced for use in World War I.
The Sopwith Camel was one of the best-known British fighter airplanes of World War I.
World War One Aircrafts During WW 1, pilots became famous for their air
to air combats, the most well-known is Red Baron, who shot down 80 planes in air to air combat with several different planes.

Aviation During WW 1: 1914-1918
1916: William Boeing's fascination with aviation leads to the creation of his own airplane manufacturing business. Over the next several decades, the company would evolve into the world's largest commercial airline manufacturer.
1918: The United States officially establishes air mail service with flights between New York City, Philadelphia and Washington D.C.

Air mail services It was the Post Office and airmail
delivery that gave the commercial airlines their true start.
In the early part of the 20th century, the Post Office had used mostly railroads to transport mail between cities.
By 1925, only seven years after the first official airmail flight, U.S. Post Office airplanes were delivering 14 million letters and packages a year and were maintaining regular flight schedules.
1925: Contract Act of 1925 (Kelly Act) Congress passes the Air Mail Act of 1925
(also known as the Kelly Act), permitting the government to hire private air carriers to deliver the mail.
The government contracts that were subsequently awarded helped determine which airlines would dominate commercial aviation - airlines including United Airlines, American Airlines and TWA.
Question
Even during the initial stage, civil aircraft were used mostly to carry post materials. But the pilots dared not fly at night due to obvious reasons. What were the reasons?
How did the problems solved?
1921: Birth of Rotating Beacons In 1921, the Army
deployed rotating beacons in a line between Columbus and Dayton, Ohio, a distance of about 80 miles. The beacons, visible to pilots at 10-second intervals, made it possible to fly the route at night Rotating light
beacon
Building of the airways
Airmail routes become Airways Lighted airway beacons—every 10
miles (1926) Intermediate Airfields - every 50
miles Airway Communication Stations
(1928) No ATC
Intermediate Airfield
Golden Age - Between Wars Large advancement in aircraft technology. Wood and canvas converts to aluminums. Engine development, In-line water
cooled gasoline engines convert to rotary air cooled engines (increase propulsive power).
After WWI, experienced fighter pilots were eager to show off their new skills.
Air shows sprang up around the country, with air races and acrobatic stunts.
1926: Ford Tri-motor: First all-metal aircraft designed for
passengers
‘Ford Trimotor’ also called as the “Tin Goose”. Can carried 12/13 passengers and could fly up 6,000 feet
(1,829 kilometre), but it’s climb to that altitude was slow, level off, bump around, and drop repeatedly before it reached its cruising altitude.
With no air conditioning and little heating, the plane was hot in summer and cold in winter,
With no circulation system, its environment was made even more unpleasant by the smell of hot oil and metal, leather seats, and disinfectant used to clean up after airsick passengers.
Opening a window was the only way to escape the smell.
1926: Ford’s Trimotor
Airline Growth 1927: Long-distance passenger
craft developed that had constant radio contact with the ground.
The Lockheed Vega takes to the skies. Allan Lockheed finally finds success with the Lockheed Aircraft Corporation.
Six people tried to do it but all died.
However, Charles Lindbergh flew solo across the Atlantic ocean successfully.
His journey cover 3,610 miles (5,815km) and took about 33 and 1/2 hours.
1927: Charles Lindbergh First flying across the Atlantic ocean
(New York-Paris) in using the Spirit of St. Louis
Parts of the ‘Spirit of the St. Louis”
Challenges faced by Lindbergh1. No sleep during flight
He had not slept in nearly twenty-four hours when he took off, so fighting sleep was the most difficult part of the flight. It is difficult to keep awake on long flight . He had to put his face outside the cockpit to allow air to blast his face and eyes.
2. Bad weatherLindbergh faced many challenges including flying over storm, fighting icing (cold), and flying blind through fog. Due to fog also he flew in poor visibility which very risky.
Challenges faced by Lindbergh
3. No radio, and no proper communication and no navigator instruments.
It is difficult to know aircraft direction and hardly to know the condition of the plane. If there was a problem, it is no way to get help.
4. No proper water survival gears – if ditched in the sea might not survive.
5. The aircraft was highly unstable, requiring constant vigilance by the pilot. Very stressful to pilot.
Question
Flying based on concept of “See and Avoid” and with no any help of flying instruments, What could be the problems faced by Lindbergh during his historic flight (33 and ½ hours)?
1929-Birth of Air Traffic Control (ATC) First airport controller (1929)
Archie League at St. Louis Airport, 1929
Charles Lindbergh Impact
Aviation became a more established. Aviation becomes respectable and
the popular Lindbergh goes on world tours to promote aviation and Pan-American Airways.
1934: Amelia Earhartand Lockheed Electra 10" mysteriously disappearedwhile on a "round the world flight.
1933: Boeing 247: First of the modern airliners (Boeing 247) developed. It could carry
13 passengers and travel at 155 mph.
Donald Douglas, the first - and youngest - aeronautical engineers in America
The company's first successful aircraft, the Cloudster, made its first flight on February 24, 1921. Later that year, the company would
change its name to simply The Douglas Company.
Douglas Airplane: Early Commercial Aviation (1933): DC-2,12 passengers (1935): DC-3, 21 passengers
DC-3
DC-3
DC-3 first aircraft to make money
In 1935, DC-3 first aircraft to make money carrying passengers rather than mail.
It seated 21 passengers and its 1,000 horsepower engine made it possible to fly coast to coast in 16 hours.
It proved air transport could be profitable. 90% of air traffic was flying on these
aircraft by 1940.
Birth of Air Traffic Control1929-1933 Light gun Control tower First radio-equipped
control tower—Cleveland (1930)
Cleveland Airport, Ohio
Birth of Instrument Flying Jimmy Doolittle’s first “blind flight”
(September 24, 1929) LFR (Low Frequency Radio Range) Four-
Course Navigation System (early 30s) First instrument airways. The end of “see and avoid”
Four-course range station
Birth of Instrument Flying New Flying Instruments developed to enable flying during night
and bad weather Visual radio direction finder:
Using vibration system to direct the aircraft. The closer the plane is to the beacon, the more intense the vibration.
Artificial horizon: Showed at what angle the plane was flying in relation to the
ground, whether and how the wings were tilted, whether the nose was up, down or level, and to what degree.
Barometric altimeter Showed how far above the ground of a particular field,. They
will sensitively record the time and therefore the distance which a sound or radio impulse travels from a plane to the ground and back.
World War 2
1939-1945
Aviation During World War 2
Drastic increase in the of aircraft development and production
Aircraft faster and more maneuverable Stronger in design Weapon systems are more sophisticated Roles are dedicated:
Fighter Bomber Attack Reconnaissane
Aviation During World War 2 1936: Spitfires (fast maneuverable fighter
airplanes) developed for use in WWII. 1943: Helicopters are mass-produced for
WWII.
Focke-Wulf Fw 190, German fighter plane of World War II.A Supermarine Spitfire was a
typical World War II fighter.
1939: Boeing 314, the largest passenger transport of its time, carrying 74 passengers and included a lounge, a dining salon, and a bridal suite. The seats could convert into 40 bunks. The manufacturer sold 12 planes to Pan American Airways, which made its first transatlantic flight

Question
Even though aircraft flight was discovered in early 1900s, civil
aviation did not go into the major industry until after the Second World
War in 1945.
WHY?
Reasons of civil aviation did not go into the major industry until after the second world war….
Since world war one government focused only on military aviation.
Economy problem and no support from government for civil aviation industry.
No demand for using aircraft as main transportation. People not traveling much.
Safety reason. People not confident with the safety in using aircraft for travel.
Limited numbers of available airliners, aircraft manufacturers and pilots at that time.
Uncomfortable. The available airliner services at that time are not comfortable for passengers.
Cold War
1945 – 1991
1945 – 1991: The Cold War
Most ex-military aircraft were used in the business of transporting people and goods.
Many companies existed, with routes that crossed North America, Europe and other parts of the world.
Heavy and super-heavy bomber airframes (e.g., B-29, Lancaster, DC-3) easily converted into commercial aircraft
1945 – 1991: The Cold War By 1952, the British state airline introduced
into service the first jet airliner, the De Havilland Comet (the plane suffered a series of highly public failures)
Other jet airliner designs Boeing 707 -comfortable, higher safety and meet passenger expectations.
In October of 1947, Chuck Yeager took the rocket powered Bell X-1 past the speed of sound (1st controlled, level flight to cross the sound barrier).
The Cold War (1945 – 1991) Further barriers of distance were eliminated in
1948 and 1952 as the first jet crossing of the Atlantic occurred and the first nonstop flight to Australia occurred.
In 1967, the X-15 set the air speed record for an airplane at 4,534 mph or Mach 6.1 (7,297 km/h).
1969, Boeing came out with its vision for the future of air travel (Boeing 747). This plane is still one of the largest aircraft ever to fly, and it carries millions of passengers each year.
In 1946, The DC-6 was the aircraft that greatly reduced traveling time with greater comfort for passengers and made air travel economically viable.
1947
1947: Airplanes fly faster than the speed of sound.
1947: Radar is developed to keep track of aircraft from the ground.
1950s
1950s: The airliner begins to replace other means of transportation as the primary means of long-distance travel.
1968: Aircraft are developed that can take off and land vertically, without the use of a runway (Harrier “Jump Jet.”).
1969: The Concorde is developed and used as the first supersonic airliner. (It crosses the Atlantic Ocean in less than 3 hours.)
The Cold War (1945 – 1991) Commercial aviation progressed even
further in 1976 as British Airways provide supersonic service across the Atlantic (Concorde).
A few years earlier the SR-71 Blackbird had set the record for crossing the Atlantic in under 2 hours.
Lockheed SR71 Blackbird
1981
1981: Space Shuttle is developed as a reusable space ship that can land after
reentry into Earth’s atmosphere.
