采用固体燃料的超燃冲压发动机研究进展

对采用固体燃料的超燃冲压发动机构型方案进行了归纳总结，详细的介绍了不同构型方案的发展历程和研究现状.针对固体燃料构型、双燃烧室构型和固体火箭构型3种不同构型的工作特点，分析了各自的优势和存在的问题，并在此基础上对其后续的研究提出了建议.研究认为:固体燃料构型方案虽能实现固体燃料在超声速气流中的点火及稳定燃烧，但燃料燃烧效率较低，且难以长时间稳定工作；固体火箭构型方案有利于燃料的点火和稳定燃烧，可实现发动机的长时间稳定工作，具有更好的研究和应用前景. 

Review of research on solid fuel scramjet engine

The configurations of scramjet using solid fuel as propellant were summarized, and the progress and status of different configurations of scramjet using solid fuel propellant were elaborated, respectively. According to the operating feature of solid-fuel scramjet, solid-fuel dual-combustor scramjet and solid-fuel rocket scramjet, the advantages and existing problems of different configurations were analyzed, and some suggestions for further research were proposed. The research results reveal that though solid fuel can ignite and burn in supersonic combustor of solid-fuel scramjet, the combustion efficiency of propellant is low and the scramjet cannot operate for a long time. The solid-fuel rocket scramjet is beneficial to ignition and stable combustion of solid fuel, and can also operate for a long time. The solid-fuel rocket scramjet has a bright research and application prospect.
