An engine that discharges a fast moving jet of fluid.
- Air is compressed by a compressor before it enters the combustor where it is mixed with fuel and ignited.
- This gas is expanded through a turbine. The power from the turbine is used to drive the compressor.
- Hot gases exiting from the turbine are expanded through an exhaust nozzle to produce thrust.
- Fuel can be added and burned downstream of the turbine.
A turbojet engine can operate efficiently from Mach 0 to 3
