摘　　要：综述了面向高轨卫星的液体轨控发动机发展及现状,简要介绍了490 N轨控发动机从第一代、第二代到第三代发展历程,着重阐述了高性能750 N轨控发动机的研制情况,并介绍了其技术方案及试验结果,总结了国内星用轨控发动机的研制经验。我国当前技术状态下,采用铌合金材料燃烧室可实现的750 N轨控发动机真空比冲性能可达到321 s以上,同时工作寿命满足25 000 s的工程需要,与国外高性能液体轨控发动机性能比对可见,我国面向高轨卫星用750 N发动机达到国际先进水平。The development and status quo of liquid orbit control engine for high orbit satellite is summarized. The development course （the first generation, the second generation to the third generation） of the 490 N orbit control engine is introduced briefly in this paper. The development status, technical so- lution and test result of 750 N high-performance orbit control engine are described. Development experi- ence of orbit control engine for satellite in China is summarized. According to current technical state of China, the specific impulse of the 750 N orbit control engine with niobium alloy combustor can reach more than 321 s, and its working life can meet the requirements of 25 000 s. Compared with the high-per- formance liquid orbit control engines in foreign countries, the 750 N engine used for high orbit satellite has reached the international advanced level.
