1903 12 17, the Wright brothers made the first test flight of a fully controlled, self-powered and heavier-than-air plane, which was the world's first plane, Voyager 1.
The airplane is one of the most important inventions in the early 20th century, and it is generally believed that it was invented by the Wright brothers in America. Their flight on 1903 17 February 17 was recognized by the International Aviation Federation (FAI) as "the first controlled sustained power flight of heavier-than-air aircraft", and in the same year they founded Wright Aircraft Company.
Since the invention of the airplane, it has become an indispensable means of transportation for modern civilization. It profoundly changed and influenced people's lives and opened the history of human conquest of the blue sky.

The first helicopter in the world
1907165438+1October13rd, the French inventor Paul Konou achieved the first vertical takeoff from the ground, but this flight greatly failed people's expectations.
The plane is equipped with a 24-horsepower engine, which drives the horizontal twin propellers to fly several times, but only for a few seconds. Once launched, the plane can't control it. Kearney's experiment is based on the performance of an unmanned helicopter model designed by Colonel Leonard several years ago. Verne's attempt was inspired by the hero traveling around the world by helicopter.
Controllable helicopter vertical flight and forward flight are finally solved by I Sicorschi in 1930. 1939, he used a single-rotor helicopter VS 300 to make many record flights in the United States.
