Jet Engine

An engine that discharges a fast moving jet of fluid.

  1. Air is compressed by a compressor before it enters the combustor where it is mixed with fuel and ignited.
  2. This gas is expanded through a turbine. The power from the turbine is used to drive the compressor.
  3. Hot gases exiting from the turbine are expanded through an exhaust nozzle to produce thrust.
  4. Fuel can be added and burned downstream of the turbine.

A turbojet engine can operate efficiently from Mach 0 to 3
