How Does a Jet Engine Work?

Jet engines which are mostly fitted on fighter aircraft are made on the principles of Newton’s third law  - “Every action has an equal and opposite reaction”. What a Jet engine does is – It sucks the air in through the fan at the front of the engine  and later this air is compressed in the compression chamber.  This high pressure air is then passes through the combustion chamber where it is ignited by fuel and air mixture. This ignites the high pressurized air sucked in and is made to escape through turbines.  These turbines also power the compressor to bring in more air and completes a cycle and forms a loop. As the ignited hot gases passes through the turbines and exits the engine, it provides a trust in the opposite direction based on Newton’s law.  The engine also works on the principle of Newton’s second law expressed here as : Force = Mass x Acceleration.

The higher the pressure and thrust created in the jet engine, the more the jet will push itself forward. Therefore, the jets known for travelling at very high speeds have jet engines which produce the maximum trust.
