摘　　要：提出一种分开排气式涡轮基连续爆震组合发动机构型,并基于GSP计算平台针对该组合发动机搭建总体性能分析模型,针对爆震燃烧模块建立气动热力学等效计算模型,根据建立的模型重点进行了发动机特性计算以及性能敏感度分析。结果表明,当采用等折合转速控制规律时,该组合发动机能在0~3马赫速域范围内工作且满足推力需求;组合发动机推力随涡轮基引气给爆震燃烧室的引气比例(文中定义为分流比)的增大呈先增大后减小趋势,推力最大时对应的分流比为0.49。A separate exhaust turbine-based continuous detonation combined engine configuration was proposed,and a general performance analysis model was built for the combined engine based on the GSP computing platform,and an aerothermodynamic equivalent calculation model was built for the detonation combustion module.The results showed that the combined engine could operate in the speed range of 0~3 Mach and meet the thrust demand when the equivalent folded speed control law was adopted;the thrust of the combined engine increased and then decreased with the increase of the ratio of the turbine-based bleed gas to the detonation combustion chamber(defined as the split fraction in the paper),and the corresponding split fraction was 0.49 at the maximum thrust.
