高超声速巡航速度获得和维持都要消耗很多燃料,通过分析它们与飞行参数的关系,给出了高超声速巡航飞行的最佳速度.在相同飞行距离下,高超巡航飞行性能和最小能量弹道的比较表明,基于火箭动力的高超声速巡航导弹在现阶段很有竞争力. The acquisition and maintenance of hypersonic cruise speed consume a lot of fuel, and by analyzing their relationship with the flight parameters, the optimal speed of the hypersonic cruise flight is given. In the same flight distance, the comparison of the super cruise flight performance and the minimum energy trajectory It shows that rocket powered hypersonic cruise missiles are very competitive at this stage.
