摘　　要：为验证液氧/甲烷轨姿控一体化推进系统涉及的主要关键技术和安全操作流程,上海空间推进研究所研制了国内首款氦气恒压挤压式液氧甲烷推进系统演示样机。历时3年,演示样机于2021年底顺利完成多轮次地面热试车考核,系统运行平稳,轨/姿控发动机工作协调、产品状态良好。介绍了演示样机的设计方案、研制历程和集成演示试验结果,以及轨/姿控发动机的设计与试验情况。液氧甲烷推进系统累计完成48次/约6000 s系统冷/热态试验考核,配套的5 kN轨控发动机累计完成点火工作40次/1860 s,配套的150 N/25 N姿控发动机累计完成稳态工作1690 s/脉冲点火约1250次。演示样机热试车的成功,标志着我国液氧甲烷空间推进系统实现了从“0”到“1”的突破,为后续型号工程应用奠定了基础,也为我国液体空间动力的升级换代和可持续发展提供了有力支撑。In order to validate the key technologies and safe operating procedures,the first integrated demonstration prototype of pressure-fed liquid oxygen/liquid methane(LO_(2)/LCH_(4))propulsion system using helium for orbit maneuver and attitude control in China has been developed by Shanghai Institute of Space Propulsion(SISP)from 2019 for the future in-space vehicles.After 3 years,the demonstration prototype was successfully completed multiple rounds of ground hot-fire tests at the end of 2021,with stable system operation,coordinated engine work and good product condition.The design scheme,development process and test results of the demonstration prototype,as well as the design and test of the orbit/attitude control engine,are introduced in this paper.The integrated propulsion system has performed a total of 48 times/about 6000 s cold state and hot-fire operations.The 5 kN orbit maneuver engine has completed the hot-fire working for 40 times/1860 s,and the 150 N and 25 N attitude control engines have completed steady-state hot-fire for 1690 s/pulse ignition for about 1250 times.The successful hot-fire tests of the demonstration prototype indicates that the LO_(2)/LCH_(4) space propulsion system in China has achieved a breakthrough from“0”to“1”,which provides a foundation for the subsequent flight applications and a support for the sustainable development of national liquid space propulsion technology.
