How was the airplane invented?

The inventors of the airplane are the famous American inventors, the Wright brothers.

The Wright brothers had a natural interest in machinery since they were children, and they liked to take apart and tinker with them since they were children. One day, their father brought back a flying spiral toy and told them that it could fly high in the air. Only then did the brother believe that in addition to birds and butterflies, man-made things can also fly into the sky. After growing up, the brothers began their mechanical aviation experiments and observed birds, beginning the development of aircraft.

On December 17, 1903, the Wright brothers made the first test flight of an aircraft that was completely controlled, relied on its own power, had a fuselage heavier than air, and could remain in the air without landing, which was the world's first aircraft, the "Aviator" Number One". Their great inventions changed human transportation, economy, production and daily life, and also changed military history.

Principles of Aircraft Flight

The cross-section of an aircraft wing is generally blunt at the front end and sharp at the rear end. The upper surface is arched and the lower surface is flat. When equal masses of air pass through the upper and lower surfaces of the wing at the same time, different flow velocities will be formed above and below the wing.

When the air passes through the upper surface of the wing, the flow speed is large and the pressure is small; when it passes through the lower surface, the flow speed is small and the pressure is strong. Therefore, at this time, the aircraft will have an upward resultant force, that is, upward lift. Due to the lift The existence of the aircraft allows the aircraft to leave the ground and fly in the air. The faster an airplane flies and the larger its wing area is, the greater the lift it generates.
