Ramjet

A ramjet, sometimes referred to as a flying stovepipe, or an athodyd which is an abbreviation of Aero thermodynamic duct, is a form of airbreathing jet engine using the engine's forward motion to compress incoming air, without a rotary compressor. Ramjets cannot produce thrust at zero airspeed, thus they cannot move an aircraft from a standstill. Ramjets therefore require assisted take off like JATO to accelerate it to a speed where it begins to produce thrust. Ramjets work most efficiently at supersonic speeds around Mach 3. This type of engine can operate up to ...
