Wright Flyer model

903

Wright FlyerWHEREAS Langley narrowly failed, two other Americans, the brothers Orville and Wilbur Wright, bicycle manufacturers, completed the final preparations that would lead them to success. Friends of noble and selfless Octave Chanute, the Wright brothers were first built in 1902, a glider inspired the work of their famous mentor. The glider with a proven, they just songèrent engined airplane essentially a virtually copied its model. In December 1903, they carried their aircraft to-Kitty Hawk, a small beach of North Carolina, and laid off a ramp. After a failed test on December 14, the Wright brothers launched for the 17, a general invitation "to all people living within a radius of 5 to 6 miles" which offers the trick was well calculated, because they were there in the desert! Nobody came, and for good reason! This lack of spectators responded to the desire of both aeronautical, who did not wish at all to disclose the secrets of their business. Assisted five assists (simple, rather illiterate, who considered these experiences as handicraft Fantasy), they saw confidently stand the dawn of December 17. The 4-cylinder engine was started, he turned perfectly, Orville Wright lie on the lower wing of the aircraft, which began on the rails of the ramp and off ... Flying against a wind of 43 km / h., the biplane moving at 60 cm above the ground when, suddenly, it rose to a height estimated at 3 meters. Moments later, he touched the ground, having covered a distance of 36.60 meters. Filmed by a camera that one aid operated, this flight was the first to be officially registered. The same day, S'alternant orders, the brothers accomplished two flights of 59.40 meters and 66 meters, then silently they rangèrent their airplane. This silence, they broke some time later to claim the implementation of the first human flight on a plane and try to sell their rights.

 


Wilbur and Orville Wright (1867-1912 and 1871-1948): the first flight of an aircraft operational


The two American brothers precursors of aviation invented and made the first airplane fly operational. Wright admired the works and exploits of the German engineer Otto Lilienthal nineteenth century and the American engineer Octave Chanute, who were experimenting with gliders and theft in general. In September 1900, on Kill Devil Hills near Kitty Hawk, North Carolina, they tested their first glider. Carefully recording their results, they concluded that the previously accepted aeronautical data on which they had relied were incorrect. In 1901, the brothers tested the effects of air pressure over two hundred surfaces of wings. In 1902, after nearly a thousand flights with a new glider, they confirmed the data obtained at Kitty Hawk.


In 1903, the brothers built their first propeller on the basis of original calculations. It proved more effective than all other propellers available at the time. Then they built a machine called Flyer I, weighing 337 kg with a 12 hp engine in which, on 17 December 1903, at Kitty Hawk, Orville made the first flight of history propelled aircraft.


On 5 October 1905, the Flyer III, the first operational aircraft in the world and led by Wilbur, flew 39 km in 38 minutes. This airplane 12 m wide could climb, descend, on a wing tilt, turn and even describe eight with ease. In 1908, Wilbur Wright in France sets new records for distance (124 km to 53 km / h) and flight altitude (110 m).


That same year the Wright brothers filled a contract with the Corps of transmissions of the U.S. Army to manufacture a plane that can fly for 10 minutes at a speed of 64 km / h. They then toured Europe, where they received numerous honors, then even their return to the United States in 1909. Wilbur became president of the American Wright Company, recently became a limited liability company. He died in Dayton three years later, on May 30 1912, of typhoid fever.
