低温推进剂在轨零蒸发贮存研究进展

摘要

采用低温制冷机与低温贮箱耦合的方式,可以实现低温推进剂在太空环境下的零蒸发贮存.从系统分析、机理研究及试验研究三个方面对低温推进剂零蒸发贮存技术的现状进行了综述,阐述了现有的系统分析方法、理论分析模型及零蒸发试验方案,可为低温推进剂空间贮存的发展提供参考.%A cryocooler integrated with the cryogenic tank can achieve zero boil?off storage of cryo?genic propellant in space. This paper summarized the theoretical and technical development of zero boil off storage in orbit, and listed several analysis methods, theoretical models and technical pro?grams, and analyzed their advantages and disadvantages. It may provide reference for the future de?velopment of cryogenic propellant storage in orbit.
