摘要
通过对国内外登月舱下降发动机的研究历史及最新进展的综合分析,提出了我国登月舱下降发动机初步方案:挤压式系统方案,重点考虑N_2O_4/MMH组合,也可以考虑LOX/煤油组合;泵压式系统方案,重点开展LOX/LCH_4膨胀循环变推力发动机技术研究。开展载人登月舱下降发动机的技术研究将对我国月球探测、火星探测等工程提供坚实的技术保障。
The conceptual schemes of China lunar excursion module descent engine （LMDE） are presented with the synthetic analysis of the research history and progress of manned LMDEs all over the world. In the pressure-fed scheme, N2O4/MMH combination is emphatically considered and LOX/Kerosene combination is all right. In the pump-fed scheme, the technologies of LOX/LCH4 expander deep throttling rocket engine is explored. It＇s sure that the success of LMDE development will be helpful to the progress of human exploration of Lunar/Mars and other plans.
