Jet engines move the airplane forward with a great force that is produced by a tremendous thrust and causes the plane to fly very fast.

All jet engines, which are also called gas turbines , work on the same principle. 
The engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The compressor is made up of fans with many blades and attached to a shaft. The blades compress the air. The compressed air is then sprayed with fuel and an electric spark lights the mixture. 
The burning gases expand and blast out through the nozzle, at the back of the engine. 
As the jets of gas shoot backward, the engine and the aircraft are thrust forward.
