氧化亚氮基单元复合推进剂技术研究述评

Review of nitrous-oxide-based composite monopropellants technology

氧化亚氮基单元复合推进剂具有无毒、高比冲、使用系统简单等诸多优异性能,有望替代传统肼类推进剂用于多种航天器。本文综述了国内外在氧化亚氮基单元复合推进剂的配方体系、发动机设计、燃烧过程及安全性等方面的研究进展,结合我国液体推进剂实际现状,提出了开展氧化亚氮基单元复合推进剂的研究思路。

Nitrous-oxide-based composite monopropellant is hopeful to substitute traditional hydrazine propellant and will be used in many kinds of spacecrafts owing to its non-toxic, high specific impulse, simple feed system and other characteristics. The research progress of monopropellants formula system, engine design, combustion process and safety is reviewed in this paper. Some advices to carry out research of nitrous-oxide-based composite monopropellant are proposed in combination with Chinese research actuality of liquid propellants.
