How a jet engine works

Ever wondered how a jet engine operates?
A jet engine works according to Newtons third law of motion : for every action, there is equal and opposite reaction.
A jet engine creates forward thrust by taking in large amount of air and discharging it at a high speed jet of gases.

- air is drawn into the engine by a fan located in front of the engine
- the air is drawn into the compressor which has blade like wings and spins fast and thereby makes it a high pressure gas
- fuel is injected into the gas and ignited
- the burning gas expand and blast out through the nozzle at the back of the engine.
The hot air leaving the engine is twice the speed of cold air entering it at the front.
