一、国外卫星飞船用的小推力推进系统发展史早期国外卫星采用的喷气推进系统是用简单可靠、技术成熟的冷气推进系统,如六十年代初期美国的“徘徊者”,“雨云”、轨道地球物理观测卫星和轨道天文观测卫星等均采用冷气推进系统。但这种推进系统比冲低,仅适用于寿命短、需要控制冲量小的卫星。与此同时国外也开始采用单元过氧化氢催化分解推进系统,1961年在水星载人飞船上已成功使用。但过氧
First, the development history of the small thrust propulsion system used by foreign satellites The jet propulsion system adopted by early foreign satellites is a simple and reliable air-conditioned propulsion system with mature technologies. For example, the “Prowler”, “Rain Cloud” Orbit geophysical observation satellites and orbiting astronomical observation satellites and so on are using air-conditioning propulsion system. However, this kind of propulsion system is lower than the impulse, which is only applicable to satellites with short life and small impulse. At the same time, foreign countries began to adopt the unit hydrogen peroxide catalytic decomposition propulsion system, which was successfully used on the Mercury manned spacecraft in 1961. But over-oxygen
