Ramjet

n. jet engine that operates by injecting fuel into the compressed air created within the engine during flight

A ramjet, sometimes referred to as a stovepipe jet, is a form of jet engine that contains no major moving parts and can be particularly useful in applications requiring a small and simple engine for high speed use; such as missiles. They have also been used successfully, though not efficiently, as tipjets on helicopter rotors.
