How does the jet engine work?
Simple. Suck, Squeeze, Bang, Blow! (What were you thinking here?)
1. Suck. Air gets sucked into the engine by the fan
2. Squeeze. The air gets compressed by the compressor blades
3. Bang. Fuel is added the the compressed air and ignited
4. Blow. The mixture is then blown out the back of the engine, creating thrust.
