The plane flew into the sky by Bernoulli's principle .

The plane flew into the sky by Bernoulli's principle . This is called Bernoulli's principle.
Because the upper part of the wing is curved and the lower part is flat, when the aircraft is moving at a high speed, the air velocity above the aircraft is slower than the lower part. The lowered air exerts a force on the wing and supports the wing, so the aircraft can go up into the sky.
The aircraft consists of five main parts: wings, fuselage, tail, landing gear and power plant.
The main function of the wing is to provide lift for the aircraft to support the aircraft flying in the air, and also play a certain role in stability and control. Ailerons and flaps are generally installed on the wings. Manipulating the ailerons can make the aircraft roll; lowering the flaps can increase the lift of the wings. In addition, engines, landing gear and fuel tanks can also be installed on the wings. There are various shapes and numbers of wings. In the early days of underdeveloped aviation technology, in order to provide greater lift, the aircraft were dominated by biplanes and even multi-wing aircraft, but modern aircraft are generally monoplanes.
The tail includes a horizontal tail (flat tail) and a vertical tail (vertical tail). The horizontal tail is composed of a fixed horizontal stabilizer and a movable elevator (the entire horizontal tail of a modern fighter plane is a movable control surface, and no special elevator is provided). The vertical tail includes a fixed vertical stabilizer and a movable rudder. The main function of the tail wing is to control the pitch and yaw of the aircraft, and to ensure that the aircraft can fly smoothly.
The power plant is mainly used to generate pull or thrust to make the aircraft move forward. Secondly, it can also provide power for the electrical equipment on the plane, and provide the gas source for the air-conditioning equipment and other gas-consuming equipment.
The power plants of modern aircraft mainly include jet engines and piston engines. There are four widely used power plants: aviation piston engines plus propellers; turbojet engines; turboprop engines; turbofan engines. With the development of aviation technology, rocket engines, ramjet engines, and atomic energy aircraft engines will gradually be adopted. In addition to the engine, the power plant also includes a series of systems to ensure the normal operation of the engine, such as the fuel supply system.
