1. 1896-1903

2. 2
Contribution of Wright Brothers to
Aviation
• (1899 - 1902) – Research on how things fly.
– literature search to find out the state of
aeronautical knowledge at their time
– read about the works of Cayley, and Langley, and
the hang-gliding flights of Otto Lilienthal
– studied the problems which had been
encountered by previous flyers and they talked
about possible solutions to the problems

3. 3
Contribution of Wright Brothers to
Aviation
• (1901 - 1902) – Tested Theories
– 1901 - built a wind tunnel and developed model-testing
techniques including a balance accurately determine the
lift and drag
– They tested over two hundred different wings and airfoil
models to improve the performance of their gliders.
– Today, NASA engineers at Ames, Langley, and Glenn
Research Centers use sophisticated models and wind
tunnels to study a variety of problems associated with
modern aircraft design

4. 4
(1900 - 1902) – Developed the first flight control
systems
– ideas for control were tested on a series of
unpowered between 1900 and 1902 – Kites to
obtain aerodynamic performance
– flying object had to be controlled about all three
primary axes; roll, pitch, and yaw
– Their aircraft were built with movable surfaces on
the wing, elevator, and rudder
Contribution of Wright Brothers to
Aviation

5. 5
• (1903 - 1920's) - Developed Propulsion Systems
– first to fly a self-propelled, heavier than air
machine
– The thin, high speed propellers which they
designed were based on wind tunnel tests and
were unlike any other propellers being used at
that time
– Between 1903 and 1913 the engine power
increased from 12 horsepower to nearly 75
horsepower

Aviation

6. 6
• (December 17, 1903) - The First Flight
• (1904 - 1907) - Flight Development
– continued to perfect their machine with a series
of aircraft built between 1903 and 1905. flight
testing from Kitty Hawk to their home town of
Dayton, Ohio
– new, more powerful aircraft, they were able to
stay aloft for up to a half hour, to fly figure eights,
and to even take passengers up for a ride

Aviation

7. Wright Bro. Solved 3 Problems
• How to obtain Lift
• How to Control
• How to generate Thrust

8. 1903 Wright Flyer
• Success of their 1902 Glider
• Planning to invented their first aircraft
• Called Flyer
• Wind Tunnel
• Experiment to determine the best wing shape
• Built the aircraft using wood
• Borrowing from bicycle technology, powered the
twin propellers, which were also made by hand.
• Completed assembly of the Flyer on the 1902
