摘　　要：为研究涡轮冲压组合发动机(Turbine Based Combined Cycle,TBCC)在超声速客机上的配装可行性,以Ma4超声速客机典型飞行任务需求为牵引,采用飞/发一体化约束分析与任务分析方法,建立了Ma4客机/TBCC发动机的一体化设计模型,确定了满足宽范围机动性需求的起飞推重比和满足航程需求的飞机起飞重量,对比分析了起飞推重比、模态转换马赫数、爬升轨迹等因素对飞机任务特性的影响。研究结果表明,TBCC发动机可满足Ma4客机配装需求,满足Ma4客机典型任务剖面机动性需求的起飞推重比应在0.6以上,满足60人商载与4000km航程任务需求的飞机起飞总重在50t^60t量级。The integration design model of the Ma4 airliner and Turbine Based Combined Cycle(TBCC)engine was built based on the typical mission profile of Ma4 airliner to research the application scheme of TBCC on the Ma4 airliner,with constrain analysis and mission analysis method.The takeoff thrust-weight-ratio and plane weight required were analyzed,and the impact of thrust-weight-ratio,mode transition Mach number,and the climb trajectory on the airplane mission characters were researched.It can be concluded that the takeoff weight of Ma4 airliner with the capability of 60-passengers payload and 4000 km range should be about 50 t^60 t,and the thrust-weight-ratio should be no less than 0.60.
