The jet engine produces much more power than propellor engines and allows planes to travel much faster – faster than the speed of sound (supersonic). Many commercial airliners and all supersonic military planes use jet engines. There are four stages in the working of a jet engine.
-
Air is sucked in through the air intake
-
Air is compressed by the compressor blades
-
Fuel is squirted into the combustion chamber where it burns continuously
-
The burnt gases expand and are blown out of the back, producing a forward force on the engine according to Newton's Third Law – to every action there is an equal and opposite reaction. As the gases move bacj=kwads they turn a turbine attached to the compressor which keeps it turning.
