Wilbur wright (A.D. 1867- 19 12) and Orwell Wright (A.D.1871-kloc-0/948) were born in a family of priests. Their mother's early death deprived them of the opportunity to go to school. When I was a child, my father bought a toy helicopter for two brothers, which aroused their strong interest in making lift-off devices and joined the local kite club.
The Wright brothers have never been to college, but 20 years' practice of making lift-off devices and their bicycle repair business have enabled them to gain rich perceptual knowledge and exquisite processing technology. They read a lot of books in their spare time and their knowledge of physical chemistry has been greatly improved.
In A.D. 1898, the Wright brothers read all the books and periodicals about flying, analyzed the causes of previous failures, and found it difficult to keep the plane stable. Therefore, they put forward a solution: when the body leans to the left and right, the curvature of the wings must be changed to create a lift difference, thus reversing the tilt. They first experimented with kites and achieved initial success. It took another year to build a glider that worked according to the above principles.
190 1 year. After many tests, the glider can fly above 100 meters, but it is difficult to make a bigger breakthrough. Later, they found that there were many mistakes in the previous empirical data. The two brothers built a wind tunnel to measure the hydrodynamic characteristics of various shapes and wings, and also made a 12 horsepower light internal combustion engine.
1903 17 February 17, the Wright brothers flew by themselves, * * * flew four times, and the last flight was 59 seconds, with a distance of 200 meters. This day marked the arrival of the first pilotable and maneuverable aircraft, and the aviation industry has developed rapidly since then.
The great success inspired the Wright brothers to move on. Soon, they built a plane that could fly for more than half an hour. 1906 was recognized and patented by the United States. 1908, the Wright brothers set up their own flight manufacturing company and accepted the first orders from the US War Department, which became the beginning of the world aviation industry and flight industry.
