The Wright Brothers
Transcript of The Wright Brothers
Over the next three years, Wilbur and his brother designed a series of gliders which looked like kites and they piloted them. Following a successful glider test, the Wright brothers built and tested a full-size glider. They selected North Carolina as their test site because of its wind, sand, hilly terrain and remote location.
In 1900, the Wright Brothers successfully tested their new 50 pound biplane glider with a 17 foot wingspan and wing-warping mechanism that was piloted in North Carolina. In fact, it was the first piloted glider ever. Based upon the results, the Wright Brothers planned to rebuild the controls and the landing gear, and build a bigger glider.
In 1901, at Kill Devil Hills, North Carolina, the Wright Brothers flew the largest glider ever flown, with a 22-foot wingspan, a weighed nearly 100 pounds. There were many problems occurred. The wings did not have enough power, and the wing-warping mechanism occasionally caused the airplane to spin out of control. They did not give up but made a wind tunnel to test many other tipes of wings for the next test flight.
1902, they used there studies with the new wings but added a tail to end of the glider to help it with better control in the air and to help it make turns. With successful test with the wind tunnel, the inventors planned to build a powered aircraft. After months of studying how propellers work the Wright Brothers designed a motor and a new aircraft. The craft weighed 700 pounds and came to be known as the Flyer.
The Wright Brothers
In 1899, Wilbur brothers had written a letter to the Smithsonian Institution for information about flight experiments, the Wright Brothers designed their first prototype : a small, biplane glider flown as a kite to test the control of the craft. 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 there wings created them to glide. They believed that they could use this technique of the bird to obtain flight control.
The brothers built a movable track to help launch the Flyer. After two attempts to fly this machine, one of which resulted into a crash. On December 17 1903 was the first successful piloted flight in history.In 1904, the first flight lasting more than five minutes took place on November 9.
