摘　　要：根据给定的运载任务,建立了氢氧全流量补燃循环发动机的能量特性模型、运载器质量模型和轨道模型,以运载器有效载荷为目标函数,利用枚举法进行了发动机性能参数的优化研究。通过计算,验证了质量模型的准确性,得到了实现单级入轨发动机的最优性能参数,给出了在当前所能达到的燃烧室压强情况下的优化结果,为新一代氢氧全流量补燃循环发动机的研制提供指导。According to the appointed carrier mission and setting the pay load of the space transportation craft （STC） as objective function, energy characteristic model, ernass model and orbit model of the hydrogen- oxygen FFSC （Full Flow Staged-Combustion Cycle） were established, and the numerical method was used to optimize the performance parameters. Through calculation, the veracity of the mass model was verified; optimized engine performance parameters for single stage to orbit were obtained and the optimized results with current level of chamber pressure were presented. This method could provide guidance for the development of the new generation hydrogen-oxygen FFSC rocket engine.
