针对高超声速飞行器俯冲段全方位攻击问题,为满足落点、速度倾角及入射方位角约束,以能量损耗最小为性能指标推导出全方位攻击最优制导律;进一步利用对称原理获得全方位俯冲制导策略,以避免在某些情况下的能量过度消耗。以CAV-H为例进行了仿真分析,结果表明该方法能高精度地满足终端多种约束,并实现全方位攻击,可为高超声速飞行器俯冲段精确制导提供参考。 Aiming at the omni-directional attack on the hypersonic vehicle subduction zone, in order to meet the constraints of landing, velocity dip and incident azimuth, the omni-directional attack optimal guidance law is deduced with the minimum energy loss as the performance index. Further, the symmetric principle is used to obtain the omni-directional subduction guidance Strategy to avoid over-consumption of energy in some situations. Taking CAV-H as an example, the simulation results show that the proposed method can meet a variety of terminal constraints with high accuracy and achieve omni-directional attack, which can provide reference for precise guidance of hypersonic vehicle subduction section.
