摘　　要：旋转爆轰发动机(RDE)具备燃烧速度快、热循环效率高、自增压、比冲大等优势,有望推动航空航天动力领域的技术革命。当前,以不同燃烧室结构和不同燃料体系为核心的基础特性研究是RDE机理性、工程化发展的重点。对此,文章详细综述了国内外最新研究进展,系统论述了RDE环形、空腔、盘形燃烧室结构和气态、液态、固态燃料体系下的喷注掺混、点火起爆、流场结构等基础性研究问题,总结了RDE在不同燃烧室结构及燃料体系应用中亟待解决的难点问题和重点发展方向。未来,旋转爆轰发动机复杂燃烧室构型设计和多相态燃料体系下的高效掺混与起爆,以及爆轰波长时间自持传播等技术问题仍需得到进一步解决。Rotating detonation engine(RDE)has the advantages of rapid combustion rate,high thermal cy⁃cle efficiency,self-boosting and large specific impulse,which is expected to promote the technological revolu⁃tion in the field of aerospace.At present,the basic characteristics research with various combustor chamber struc⁃tures and fuels as the core is the emphasis of RDE mechanism engineering research.In this paper,the latest re⁃search progress at home and abroad is summarized in detail,and the basic research problems such as the struc⁃ture of RDE annular,hollow,disk combustors and the flow field structure of injection and mixing,ignition and initiation in gas-liquid-solid fuels are systematically discussed.The difficulties and key directions which need to be solved urgently in the application of RDE with different combustor structures and fuels are summarized.In the future,the design of complex combustion chamber strutures of RDE and the technical problems of efficient mix⁃ing and ignition,and the long-term self-sustaining propagation of detonation wave in multiphase fuels still need to be further solved.
