A review of the latest progress in three sorts of green liquid propellant,including monopropellants,bipropellants and atomic propellants,has been presented.
硝酸羟铵基单组元推进剂具有冰点低、密度比冲高、安全无毒的特点,适用于小卫星和上面级,催化分解技术还有待深入研究;二硝酰胺铵基单组元推进剂比冲高于硝酸羟胺基单元推进剂,发动机脉冲工作能力可与无水肼发动机相媲美,但目前发动机预热温度和燃烧室温度都过高;高浓度过氧化氢/醇基推进剂比冲为常规推进剂比冲的93%,密度比冲为102%;过氧化氢/叠氮胺类不但密度比冲高,而且可实现自燃;一氧化二氮基双组元推进剂在微推进系统中有广泛的应用前景;原子推进剂以其优良的比冲性能将给航天运载器带来革命性的飞跃,但对低温技术提出了挑战。
