摘要
构建了包括前体/进气道、燃烧室、尾喷管/后体的一体化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.进行了燃料为氢的超燃冲压发动机/机体一体化优化设计,对优化设计得到的超燃冲压发动机/机体一体化构型进行了二维数值模拟.计算结果表明:氢燃料超燃冲压发动机/机体一体化性能计算程序准确性较好,优化结果具有较高可信度.
A performance calculation program and an optimization design platform of integrated scramjet/airframe,including three main parts：forebody/inlet,combustor and nozzle/afterbody,were developed in this paper.The hydrogen-fueled,integrated scramjet/airframe configuration optimization design was performed based on the optimization design platform.The integrated scramjet/airframe two-dimensional configuration of optimized design was numerically simulated.The calculation results indicate that the performance calculation program of integrated scramjet/airframe is exact and the optimized design result is reliable.
