1.绪言火箭/冲压发动机,是使火箭的不完全燃烧生成物与进入飞行体的冲压空气进行再燃烧的发动机。有人称它为管道火箭或简称冲压火箭。因为大部分氧化剂由空气代替,所以这种发动机不仅经济性好而且比推力也有所提高。特别是在火箭中采用固体推进剂时,火箭发动机不仅兼有燃料箱,燃料泵及燃料喷射阀的机能,而且也兼作从火箭发动机(下称一次燃烧室)喷管向冲压发动机燃烧室(下称二次燃烧室)喷出的一次燃烧生成物进行第二次燃 1. INTRODUCTION The rocket / ramjet engine is an engine that re-combusts rocket incomplete combustion products with ram air entering the aircraft. Some call it a pipeline rocket or simply stamping rockets. Because most of the oxidizer is replaced by air, the engine is not only economical but also more powerful than thrust. In particular, the use of solid propellants in rocket engines not only incorporates the functions of fuel tanks, fuel pumps and fuel injection valves, but also serves as a fuel injection system from the rocket engine (hereinafter referred to as “primary combustion chamber”) to the ramjet combustion chamber Called the second combustion chamber) the first combustion products emitted second combustion
