Research on Large Thrust Liquid Rocket Engine

Large thrust rocket engine is the basic of aerospace development and the present of high tech level and comprehensive national strength. The development condition and trend of launch vehicle main power system is analyzed, and the large thrust LOX/Kerosene rocket engine and LOX/LH2 rocket engine are the development trend and the best combination in the future is put forward. In this paper, the general scheme and main parameters of large thrust LOX/Kerosene rocket engine and LOX/LH2 rocket engine for heavy launch vehicle are researched, and the key technology and resolvent is put forward. The two kinds of large thrust engines will offer power for space using, momentous space activities of manned lunar and deep space exploration.
