摘　　要：组合发动机是高超声速飞机、临近空间高超声速飞行器、水平起降两级入轨航天运输系统之一级等高超声速飞行器研发必须研究的动力装置,是当前航空航天届非常关注的热点技术。组合发动机正处于关键技术集成阶段,发动机内流道的气动特性、多模态燃烧、系统结构匹配及可靠性等关键技术研究涉及的研究手段尚不完善。组合发动机后续研究要解决大尺度发动机流道匹配、大尺度燃烧室、力学环境试验、模拟试验设备等问题,需在研究思路、关键技术攻关途径方面持续创新。The combined engine is a necessary power device for the development of hypersonic aircraft, near space aircraft, and the first stage of the TSTO space transportation system, and it is a popular technology in the current aerospace industry.The combined engine is in the integration stage of key techniques, and the research means of inner flow characteristics, multi-mode combustion, system structure matching and reliability are not perfect.In order to solve the problems such as flow-tube matching of large-scale engine, similarity law of large/small scale combustion structure, mechanical environment experiment, simulation test facility and so on, the continuous innovation is required in research ideas and approaches of key techniques.
