在第一章中就已经指出推进系统依推力产生装置(推力室)区分为三大类,即涡轮喷气式,冲压喷气式的火箭式动力系统。一般说来,组合推进系统就是在上述主要类型中组合两种所构成,这样共有三种可能的组合推进系统,即:(1) 涡轮一冲压式; In the first chapter, it has been pointed out that the propulsion system is divided into three major categories according to the thrust generating device (thrust chamber), that is, turbojet, ramjet-type rocket power system. In general, the combination propulsion system is composed of the above two main types of combination of two, so there are three possible combinations propulsion system, namely: (1) a turbine-type stamping;
