摘要： 基于空间发动机系统质量模型和质心漂移模型，进行了燃烧室压强及气瓶形状优化分析。研究结果表明：①燃烧室压强最佳值为１ＭＰａ，此时发动机系统质量最小；②采用环形气瓶具有优势，发动机系统质量较小，没有质心漂移。

Abstract: Based on mass models and models of drift for pressure-feed, liquid propellant space engines system, optimization and analysis of combustion chamber pressures and gas tank shape are carried out in this paper. Some important conclusions are obtained: ① Total mass of the space engines system is reduced to a minimum with optimal pressure value of 1MPa; ② For the space engines system with annular gas tanks, the system mass is smaller and the drift of center of mass of a spacecraft is zero.
