本发明介绍一种改进的火箭发动机。为把固体火箭发动机的重量减到最小,曾提出把两种不同的药柱合并到一个发动机中,即在这种发动机内,一种药柱即含有燃料又含有氧化剂,因而能够自身维持燃烧,另一种药柱虽然含有燃料,但缺乏氧化剂,或并氧化剂是不足的,因而不同氧化剂接触时,就不能维持燃烧。这样一种火箭发动机可由自身可燃的药柱的燃烧 The present invention describes an improved rocket engine. In order to minimize the weight of a solid rocket motor, it has been proposed to combine two different types of pellets into a single engine, where one pellet contains both fuel and oxidizer and is therefore capable of sustaining combustion on its own, Another type of pellet, although containing fuel, lacks an oxidizer or oxidizer and is insufficient to maintain combustion when different oxidizers contact. Such a rocket engine can be combusted by its own combustible cartridge
