The First Man to Fly 1896-1903
Who are Wright Brothers? • Two Americans brothers. • Inventors of the world's first successful airplane. Wilbur and his brother Orville
Wright Brothers Journey • 1899 - 1902 – Wright Brothers maderesearch on how things fly. • 1901 - 1902– Wright Brothers tested their wings using wind tunnel. • 1900 - 1902 – Wright Brothers developed the first flight control systems. • 1903 - Wright Brothers developed propulsion system (generate thrust by engine and propeller) • 17th December 1903, finally successful
4 (1899 - 1902) – Wright Brothers madeResearch on how things fly. • Wright Brothers made a research to find out the state of aeronautical knowledge at their time • They 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
6 (1901 - 1902) – Wright Brothers Tested Their Wings using Wind Tunnel • 1901 - Built a wind tunnel and they tested over two hundred different of wing and airfoil models to improve the performance of their gliders. • Today, aircraft engineers use sophisticated models and wind tunnels to study a variety of problems associated with modern aircraft design
Wind Tunnel: research tool to study the effects of air moving past solid objects. NASA wind tunnel with the model of a plane.
13 (1900 - 1902) – Wright Brothers 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
19 (1903 - 1920's) - Wright Brothers 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
21 December 17, 1903) - The First Flight • December 17, 1903, near Kitty Hawk, North Carolina, Wilbur and Orville Wright made the world's first successful powered, free, controlled, sustained flights in a heavier-than-air craft. Their first flight went 120 feet (37 meters) and lasted only about 12 seconds.
SummaryWright Bro. Solved 3 Problems • How to obtain LIFT FORCE using the wing. • How to make 3-axis aircraft control possible. • How to produced THRUST force using engine.
(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
After 1903……. The brother write to the war department to try and obtain a contract for a “practical flying machine” but are turned down. They decide to halt flying operations until they get a contract and the patent rights. They won’t be seen in the air again until 1907 but they continue to work on increasing the power of their engines.
1908…formed the Wright Company • Finally in 1908 the War Department signed a contract for a Wright Flyer, provided it could meet certain tests. • A month later a plan was instituted for the formation of a Wright company in France. • After the successful development of the first airplane, the Wright Brothers continued to be involved in aerospace technology. • Orville was one of the original members of the National Advisory Council on Aeronautics (NACA) which is the parent organization of the current NASA.
Wright Brothers Contribution • Transportation change dramatically. • By mid-century air travel was common • By late 1950s it had replaced the train and stream ship as the preferred mode of transport. • By the last quarter of the 20th century, with large, efficient jet-powered aircraft, air travel was commonplace and affordable to all. • Flying has become second nature to hundreds of millions of people and it is impossible to imagine a world without it.
Wright Brothers Contribution • Airplane also rapidly developed as weapon of war. • The advent of jet power, and sophisticated electronics perfected during and after Cold War, has now turned the aircraft into a feared weapon. • Today, aviation and spaceflight are critical tools for the improvement of human conditions and powerful instruments of positive change. • The political, social and economic challenges are different.
