CSTS 返回舱气动布局研究
Aerodynamics configuration study for CSTS reentry capsule
摘要
Abstract
The Crew Space Transportation System (CSTS)is a proposed next generation manned explo-ration vehicle which will transport crew both to the ISS in Low Earth Orbit,and to Low Lunar Orbit.In this paper,orthogonal numerical experiment with four factors and three levels was arranged,using the orthogo-nal experimental design method.The influence of geometric parameters on the aerodynamic characteristics was discussed,aiming at finding the configuration with the highest L/D value.After selecting the configura-tion,the trim L/D line was found out for the required L/D .The placement of the center of gravity on the trimline which affects the pitch static stability and the aerodynamic sensitivity to the placement was investi-gated for better aerodynamic perfermance.关键词
