Combined supersonic/hypersonic combustion ramjet has air injector system for reflection of supersonic intake air

摘要

The system has a high pressure compressor, which feeds compressed intake air into a combustion chamber. A small nozzle generates an injector jet to suck fresh air into larger jet system. This is a combined combustion ramjet, which works with dynamic pressure effect at high speeds. The jet system is mainly formed by a tube, with an adjustable constriction at the front end. The injection nozzles are placed at this point, so that the combustion ramjet can also burn fuel. The air intake is formed so that the air is deflected through 45 deg , to pass through the constriction.
