How does a jet engine works?

A jet engine works by sucking air in the fan at the front of the engine. From the fan section the air enters the compression section which further squeezes the air down. After this the air is moved to the combustion section which just as the name suggests ignites a fuel air mixture. The air then travels through two turbine sections, a high and a low pressure turbine section each respectively connected to the compressor and fan sections, thus providing the jet engines self-sustainablility. After all this the air exits the rear of the engine pushing whatever the jet is attached to forward. This is the basic process of a low-bypass jet engine.

Air flows into the inlet fan, which pushes the air back farther into smaller fans that push the air into a combustion chamber. In the combustion chamber, the air is ignited with fuel, creating an explosion which is pushed out the back of the engine as warm air and as thrust to push the airplane along. Also, some cold air actually goes around the main engine, not in it, and out the back as regular air. This actually provides over 50% of the airplane's thrust.

How a jet engine on a jet plane works?

A jet engine works basically the same as any engine. It compresses air, then injects fuel and ignites it with the result that the fuel/air burns and expands which produces work. Air is brought in the engine and turning blades compress the air and pushes it further back. When it gets to the combustion chamber, fuel is injected and the gas is ignited. The fuel/air burns and expands and flows faster out the back. As it does, it turns the turbine blades which are connected by a shaft to the front blades and keeps the engine turning.
