A scramjet is a type of jet engine that USES compressedair in place of conventional turbines to create thrust. Read "U." S. Developing Jets that Fly Five Times the Speed of Sound.

When a jet engine is running, a fan at the front draws in air, which is then compressed and burned with fuel to produce hot, rapidly expanding gases which roar out of the back.
Because the utility model is provided with the compressedair inlet and the jet nozzle, the energy consumption is low and the silk suction effect is favorable.
