Types of jet engines:
The Ramjet engine require a relatively high speed to compress the incoming air, they cannot work standing still.
The Scram jet engine is basically the same thing as a Ramjet but does not slow down air through the inlet. And they both compress air differently.
The Prop fan uses a gas generator to power a fan, Prop fans are not in production yet.
Turbojet mixes compressed air with fuel then burns the mixture, then uses the exhaust for thrust.
Turboprop extracts work from the hot exhaust to turn a propeller.
