How a Jet engine works?

1. The fan sucks air from the front side and some of the bypassed air passes only through the fan. The compressor sucks in and squeezes the air. The pressure of the air increases when the air is squeezed. In the combustion chamber, jet fuel is mixed with air and ignited, which can cause fire.
2. As the air expands, its velocity increases. Then it blasts out from the back side of the engine. That forward force is called “Thrust”.
3. The high energy fluid rotates the turbines which drive the compressors and the fan.
4. The air pressure decreases when it passes through the turbines.

So, that’s how a Jet engine works.
