星球着陆下降发动机及我国登月下降发动机设想

Lander descent engine and assumption of Chinese LMDE

星球着陆下降发动机探测器在外星上进行软着陆时起着关键的作用,目前我国还没有进行软着陆的成熟的发动机,对比较典型的月球和火星着陆下降发动机的特点和种类进行总结,提出了我国着陆下降发动机的方案设想,为我国着陆下降发动机的研制提供技术支持。

The lander descent propulsion system plays an important role in soft landing of planet explorer. There is no mature soft-landing engine in China nowadays. The typital Lunar excursion descent engine system and Mars explorer descent engine are introduced. The trend of development in this field is pointed out and the assumption of Chinese LMDE is proposed in this paper. It will provide a technical support for Chinese descent propulsion system.
