Jet engine

In the jet engine there is no propeller. When the hot exhaust gases have passed through the turbine they are channelled into a narrow nozzle that makes them come out of the back of the engine at high speed.


This high speed jet of gas moving in one direction gives the engine a velocity in the opposite direction. The greater the velocity of the exhaust gases the greater the velocity of the plane.
As in the turboprop the exhaust gases turn the compressor, the motion of the plane drives more air in.
