Before the invention of jet aircraft, aircraft were powered by fuel piston engines. When the engine works, the propeller in front rotates at high speed, which gives the power for the arrival and advance of the aircraft. However, this kind of piston aircraft has a disadvantage, that is, it is difficult to improve the speed of the aircraft.
The invention of the real jet aircraft was inseparable from Frank whittle. In the late 1920s, whittle found the limitations of the piston engine, so he came up with the idea of using the jet generated by the engine to drive the aircraft. Today we collected some jet tattoos. I hope these tattoos can inspire you.
