  • About author:FAN Ruixiang (1965- ) received his Ph.D degree in Department of Material Science and Engineering from Harbin Institute of Technology in 1991. He has been working at China Academy of Launch Vehicle Technology (CALT) since 1991. Now, he is the chief designer of the Long March 7 launch vehicle. In addition he is a member of the Expert Committee on the Space Commission of the CMC, and a member of the International Academy of Astronautics (IAA).

Abstract: The reliable and intelligent propulsion pressurization system is one of the key technologies of new Chinese generation launch vehicles; a high reliability design is an important guarantee for the success of launching. This paper analyzes the domestic and overseas liquid launch vehicles in the area of propulsion pressurization systems, based on comprehensive analysis, demonstrating the reliable and intelligent propulsion pressurization system of the Long March 7 (Simplified as LM-7) has been raised. By applying a full chain redundancy design, setting proper pressure control bandwidth and control mode reconstruction under extreme fault conditions, the reliability and adaptability of the propulsion pressurization system has enhanced significantly. In addition, the complete system has been verified by the first two flights of LM-7.
