- Abstract:
- A lunar lander descent engine with throttle-ability, high thrust, high performance and restart capability is needed for manned lunar landing mission in the scheme demonstration. According to the present state and trend of descent engines in other countries, based on the technology of Chinese LH2/LOX rocket engine and the space storage level of cryogenic propellant in orbit, the system study of deep throttling rocket engine was carried out. The characteristics of expander and generator cycle engines were analyzed. The turbo-series close expander cycle engine was demon- strated as the engine system scheme. It is pointed out that the CH4/LOX propellant which can be stored in space for a long period can satisfy the requirements in mission period. According to the performance requirements of each assembling unit while the thrust is adjusted deeply, the combustion stability technology of injector and the heat transfer technology of combustor body are identified as the key ones for
