Step 5 - Ahmed Hamza Ahmed

  1. 1. Orville Wright (1871-1948) and Wilbur Wright (1867-1912) requested a patent application for a "flying machine" nine months before their successful flight in December 1903, which Orville Wright recorded in his diary. Earlier in 1900, Wilbur Wright wrote to French aviation pioneer Octave Chanute (1832-1910) and expressed the belief that "flight is possible to man...[and] I feel that it will soon cost me an increased amount of money if not my life". More on the Wright Brothers' invention of the airplane.
  2. 2.  The Wright Brothers spent a great deal of time observing birds in flight. They noticed that birds soared into the wind and that the air flowing over the curved surface of their wings created lift. Birds change the shape of their wings to turn and maneuver. They believed that they could use this technique to obtain roll control by warping, or changing the shape, of a portion of the wing.
  3. 3.  Over the next three years, Wilbur and his brother Orville would design a series of gliders which would be flown in both unmanned (as kites) and piloted flights. They recognized that control of the flying aircraft would be the most crucial and hardest problem to solve. In 1900, the Wrights successfully tested their new 50-pound biplane glider with its 17-foot wingspan and wing- warping mechanism at Kitty Hawk, in both unmanned and piloted flights. In 1901, at Kill Devil Hills, North Carolina, the Wright Brothers flew the largest glider ever flown, with a 22-foot wingspan, a weight of nearly 100 pounds and skids for landing
  4. 4.  During 1902, the brothers flew numerous test glides using their new glider. Their studies showed that a movable tail would help balance the craft and the Wright Brothers connected a movable tail to the wing-warping wires to coordinate turns. With successful glides to verify their wind tunnel tests, the inventors planned to build a powered aircraft.
  5. 5.  After months of studying how propellers work the Wright Brothers designed a motor and a new aircraft sturdy enough to accommodate the motor's weight and vibrations. The craft weighed 700 pounds and came to be known as the Flyer.
  6. 6.  The brothers built a movable track to help launch the Flyer. This downhill track would help the aircraft gain enough airspeed to fly. After two attempts to fly this machine, one of which resulted in a minor crash, Orville Wright took the Flyer for a 12-second, sustained flight on December 17, 1903. This was the first successful, powered, piloted flight in history. In 1904, the first flight lasting more than five minutes took place on November 9. The Flyer II was flown by Wilbur Wright.
  7. 7.  Both the brothers never got married. Wilbur Wright was the first of the two to die. He got ill with Typhoid fever in 1912. He died on May 30, 1912 of this fever. He was only 45 years of age. On the other hand. Orville died of a heart attack. It was in the year 1948, when he had his second heart attack. They are both buried in Woodland Cemetery, Dayton, Ohio.
