Ramjet engines. Diffuser. Combustion chamber. Nozzle. Supersonic compression. Subsonic compression. Flame holders. Schematic of typical ramjet engine Combustion Ramjet (SCRAMJET) in which the combustion is done in supersonic flow. There are two main uses of Ramjet Engine: In some Aircraft propulsion systemThe ramjet engine is similar in principle to the tur- bojet but relies completely on its forward velocity to supply high-pressure air for the combustion On: entering the engine. I is the specific impulse which is inversely proportional to the specific fuel consumption. The total temperature ratio for the The turbojet and turbine-propelier engines have thus far been limited in power output by the temperature limitations of the turbine materials. The ram jet A ramjet, sometimes referred to as a flying stovepipe or an athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the engine's
