摘　　要：吸气式高超声速巡航飞行器机身/发动机一体化特性使得气动-推进系统之间存在强的耦合作用,这种耦合影响着飞行器气动性能、稳定性和控制。针对耦合对飞行器特性的影响,建立了机身-发动机一体化模型,并进行了气动-推进界面划分。在此基础上,分别计算了高超声速巡航飞行器在进气道打开,发动机不工作以及进气道打开,发动机工作两种状态下的纵向气动特性。仿真结果揭示了高超声速巡航飞行器气动-推进系统之间的耦合以及耦合作用对飞行器气动性能、稳定性的影响。The airframe integrated nature of the scramjet engine with airbreathing hypersome eruise vehicle （HCV） results in a strong couplings between aerodynamics and propulsive system. The couplings have an effect on vehicle aerodynamic performance, stability and control. Aiming at the effects, the model of airframe integrated scramjet engine has been developed and aero-propulsion interface separated. Based on the forgoing work,longitudinal aerodynamic characteristics of HCV inlet open, scramjet engine powered and unpowered have been computed separately. Simulation reveals the couplings between aerodynamics and propulsive system and the effect on vehicle characteristics.
