摘　　要：构建了包括前体/进气道、燃烧室、尾喷管/后体的全流道超燃冲压发动机性能计算程序和优化设计平台,对性能计算程序的适用性进行了验证。进行了氢燃料变几何燃烧室的全流道超燃冲压发动机优化设计。设计结果表明,变几何燃烧室超燃冲压发动机性能得到提高。A performance calculation program and the optimization design platform of full-flowpath scramjet were set up,including the three main parts of forebody/inlet, eombustor and nozzle/afterbody. Aiming at hydrogen fueled, the full-flowpath scramjet configuration optimization design was performed based on the optimization design platform. The results indicated that the performance of variable-geometry combustor scramjet is improved.
