The first man to 'fly' ..wright brothers

  1. 1. 1896-1903
  2. 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. 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. 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. 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 Contribution of Wright Brothers to Aviation
  6. 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 Contribution of Wright Brothers to Aviation
  7. 7. Wright Bro. Solved 3 Problems • How to obtain Lift • How to Control • How to generate Thrust
  8. 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
  9. 9. BIBLIOGRAPHY • WRIGHT BROTHERS • Wright Brothers Encylopedia • The Wright Brothers Biography • Wright Brothers Astronomy • Wright Brothers Contribution In Aviation Lecturer • Capt Zulkifli B Mat Ariffin AMIDEE
