摘　　要：涡轮增压固体火箭冲压发动机(Turbocharged Solid Propellant Ramjet,TSPR)是将固体燃气发生器驱动ATR与冲压发动机相结合的新型发动机循环,是加力ATR的特有形式。建立TSPR热力分析模型,分析了关键部件参数对发动机性能的影响规律。在发动机部件约束条件下对比ATR和TSPR的工作包线以及比冲、比推力性能,确定了TSPR在工作范围和能量特性的优势,提出了TSPR三个应用领域。对比四种不同加力推进剂的TSPR性能,获得了TSPR不同工作要求的加力推进剂的优选标准。Turbocharged Solid Propellant Ramjet （TSPR） is a new cycle combining SPATR （solid propellant gas generator air turbo ramjet） with solid ramjet,it is special feature of augmented ATR. The thermodynamic model of TSPR was built and the relationship between key component parameters and engine performance was the analyzed, the speed-altitude operation envelopes of ATR and TSPR which were constrained with the component were compared , and results shows TSPR has wild speed-altitude operation envelopes and excellent special impulse and special thrust, based on these advantages , three potential application were listed. Four kinds of fuel system are used as augment fuel for TSPR, and get select standard of augment fuel in different mission request.
