摘要

摘要: 针对典型飞行马赫数Ma=8~10高超声速飞行器/超燃冲发动机一体化构型，建立了飞/发性能一体化模型，可以快速评估飞行器气动力、发动机性能和飞行任务性能。对比了在起始推重比为0.3、0.4、0.5和0.6下的飞行器飞行性能，以燃料消耗最小为目标，基于飞/发性能一体化模型，利用MATLAB优化工具箱中的序列二次规划（SQP）算法，得到了该飞行器的最优起始推重比为0.422。给出了Ma=8~10飞行器/发动机的概念方案总体参数，在载荷质量为1 000 kg下，飞行器总质量为5 943 kg，发动机推力为2 505 daN。该飞行器在攻角范围为4.1°~3.8°下总的飞行时间为489 s，飞行距离为1 360 km。

Abstract: Targeting a flight Mach number Ma=8-10 hypersonic vehicle and scramjet，an integrated performance model of vehicle and engine was built.The model can fastly evaluate the aerodynamics of vehicle，propulsion performance of engine and flight performance.The flight performances under different take-off thrust weight ratios of 0.3，0.4，0.5 and 0.6 were compared.The optimal take-off thrust weight ratio of 0.422 was obtained，with object of minimum fuel consumption，using the MATLAB optimization tools of sequence quadratic program （SQP） algorithm based on the integrated performance model of vehicle and engine.The overall parameters of the Ma=8-10 vehicle and engine conceptual scheme were given.The total mass of vehicle was 5 943 kg with the load mass of 1 000 kg.The thrust of engine was 2 505 daN.The flight time of the vehicle was 489 s with the attack angle range of 4.1° to 3.8°.The total flight distance was 1 360 km.
