The Wright brothers, pioneers of Air

The Wright brothers, pioneers of Air

On December 17, 2012, were met 109 years of that historic day when the Wright brothers became the pioneers of the air with his historic first controlled flight in a machine heavier than air. We remember his feat, which now gives us this incredible ability to move from one place to another planet in an easy, safe and cheap occasionally.

Wright Flyer I flew in Kill Devil Hills, North Carolina.

Orville and Wilbur Wright, to reach this historic moment, had a long and interesting process. None of the two brothers managed to receive a certificate for having completed high school. Wilbur finished it but did not get his diploma because his family moved from Indiana to Ohio, on the other hand Orville dropped out of school to start his printing business where he designed and built his printing press. Subsequently both brothers started a new business repairing and selling bicycles. Eventually, with his great ability to design and manufacture created their own line of bikes that eventually generated enough success, reflected in money, to open five stores in the Wright Cycle Company in Dayton, Ohio and finance their experiments in aeronautics.

Wilbur, the great leader of the brothers, had a major fixation with development planners such as Otto Lilienthal in Germany and Octave Chanute in Illinois. His fixation led to directly contact the Smithsonian Institution for more knowledge about aviation and some historical designs. With the knowledge gained from the experiments of Lilienthal and Chanute, Wilbur in 1899 began to experience the first concepts of aviation with a glider with a wingspan of 1.5 meters was used as kite. With wings tied 4-point lift and experimented with motion control of his glider in flight. Between 1899 and 1902 the Wright brothers had hundreds of test flights with its three gliders, plus hundreds of other tests with different wings and airfoils in the wind tunnel of almost 2 meters Wilbur built.

By December 1903, the Wright brothers were ready to experience the chance to fly their flying machine with a motor. They set a course in Kill Devil Hills, North Carolina where the conditions for their experiments were successful, nice sandy hills and wind. In his fourth visit to Kill Devin Hills, 7 miles south of Kitty Hawk, had added an engine to his glider and prepared to test the vehicle. The Wright Flyer I , was made of wood giant firs , an asymmetric airfoil camber, with wings of a very thin cotton and sealed with fabric paint. No engine met the specifications needed by Wright for their flight, which was built by an engine of an aluminum alloy and copper with 4-cylinder, 12 hp at 1150 rpm with two 2.4 meter against propellers rotating at 350 rpm.

The weeks before its first flight had major problems with both propeller shafts broke on a couple of occasions. Finally on December 14 prepared for their historic flight, again one of the propellers failed which caused Wilbur had a minor accident. Three days after the Wright Flyer I managed was placed back in its catapult made of 2×4 lumber and 10:35 am, Orville took off and controlled the small plane 6.4 meters long with a wingspan of 12.2 meters. The Orville flight lasted only 12 seconds which allowed him to move a distance of approximately 36.5 meters.

That same day, Wilbur and Orville flew three other occasions, the second flight piloted by Wilbur was 53 meters, the third flight by Orville piloted again was almost 70 meters. The last flight of the day, happened right at noon when sufficient experience Wilbur flew 260 meters and remained in the air for about 1 minute. Orville was left with the desire to continue flying that day because the wind damage the plane again. They decided to return to Kitty Hawk to send a telegram to her father to report the results of his trip to the press, who ignored them.

The Wright brothers’ company, the Wright Brothers Aeroplane Company , bequeathed another 17 planes after the Flyer I between 1903 and 1915 when Orville sold the company. The basics of aerodynamics that your flight Wright perfected 109 years ago are still used today in our aircraft, we must remember how those pioneers who revolutionized the transportation of the twentieth century and the future.
