Ramjet Engine


an air-breathing jet engine in which air entering the engine’s combustion chamber is compressed during flight by the action of the ram effect.

ramjet engine

[′ram‚jet ‚en·jən]
(aerospace engineering)
A type of jet engine with no mechanical compressor, consisting of a specially shaped tube or duct open at both ends, the air necessary for combustion being shoved into the duct and compressed by the forward motion of the engine; the air passes through a diffuser and is mixed with fuel and burned, the exhaust gases issuing in a jet from the rear opening.
