Are jet planes all fighters?

No, a jet plane is an airplane that uses a jet engine as its propulsion source. According to the source of propulsion, aircraft can be divided into propeller aircraft and jet aircraft. According to the purpose, it can be divided into fighter, bomber, reconnaissance plane and passenger plane. At present, most of the fighters in active service are jet planes (a few countries still use propeller fighters). However, many reconnaissance planes, passenger planes and attack planes are jet-type, such as sr7 1 and a 10, and China's Flying Leopard.

The jet plane is equipped with an air compressor in front of the engine to push the gas back step by step. The concentration of gas is getting stronger and stronger, and the pressure is getting bigger and bigger. When the gas passes through the last stage, the gas pressure increases many times. And then enters the combustion chamber. In the combustion chamber, electricity is injected to strike a fire, and oil is injected to burn. Because the gas contains oxygen, the gas burns and expands and ejects backward. Behind the combustion chamber is a turbine, and a turbine disk is mounted on the turbine shaft, and the circumference of the turbine disk is covered with blades. The steam turbine is divided into 7- 13 stages. After the turbines rotate, they press backward one by one, and the gas is compressed by the turbine behind the engine, and the pressure increases by hundreds of times. Finally, a reaction force is generated to make the plane fly forward.
