Related to ramjet: ramjet engine, scramjet


A jet engine that propels aircraft by igniting fuel mixed with air taken and compressed by the forward motion of the aircraft.


(ˈræmˌdʒɛt) or

ramjet engine

a. a type of jet engine in which fuel is burned in a duct using air compressed by the forward speed of the aircraft
b. an aircraft powered by such an engine



a jet engine operated by fuel injected into a stream of air compressed by the aircraft's forward speed.


A jet-propulsion engine containing neither compressor nor turbine which depends for its operation on the air compression accomplished by the forward motion of the engine. See also pulsejet.
