【摘要】 从一体化的角度，进行了高马赫数飞机飞/发一体化性能初步分析。将飞行轨迹分段并以平均加速度考虑，运用积分计算的方法，得到在不同推重比、不同比冲下，燃油+动力系统质量分数随平均加速度和飞行马赫数的变化规律。研究发现，对于升力体类的高速飞机，当加速至6马赫时，加速阶段的平均加速度在0.15g～0.20g范围内较为合适；若平均加速度大于0.20g，在相同巡航速度和航程下，燃油质量分数随加速度的增大而增大；若平均加速度小于0.05g，会使得飞机航程大大减小且速度提升慢，燃油主要消耗在加速度段。提出的方法和研究结果，为高马赫数飞机飞/发一体化设计和性能评估提供了有力参考。更多还原

【Abstract】 The performance evaluation of high Mach number aircraft/engine integrated design was carried out. Segmenting contrail and taking average speed into account, in the mean time, by using integration method, the changing law of percentage of parts of engine and fuel system varies with acceleration under different thrust to weight ratio and specific impulse. The investigation results show that the mean acceleration speed between 0.15g and 0.20g would be better for wave rider aircraft when it needs to reach Mach 6. If the mean acceleration speed is more than 0.20g, the fuel mass fraction will increase as acceleration speed increases under the same cruise speed and range. If the mean acceleration speed is smaller than 0.05g, the flying range would be much shorter and acceleration time would be longer, furthermore, the fuel consumption would be much bigger during acceleration. The performance evaluation method proposed and investigation results provide reference for high Mach number aircraft/engine integration design.更多还原
