吸气式高超声速导弹巡航段侧向机动能力分析与仿真

Analysis and Simulation of Lateral Maneuver Ability of Aspirated Hypersonic Missiles in Cruise Phase

针对吸气式高超声速导弹在巡航段侧向机动实现与多项约束限制的矛盾,采用STT和BTT混合控制方式,设计了侧向过载指令的生成方法,完成巡航段侧向大机动的作战需求。分析吸气式高超声速导弹巡航段为满足超燃冲压发动机正常工况所面临的各项约束,在满足约束的前提下设计STT和BTT混合控制的策略,针对具有过载式三回路自动驾驶仪的吸气式高超声速导弹进行巡航段仿真。仿真结果表明,所设计的混合控制策略可以提高吸气式高超声速导弹的侧向过载能力,以满足侧向大机动的作战需求。

In view of the contradiction between the realization of lateral maneuver of aspirated hypersonic missiles in cruise phase and multiple constraints,the generation method of lateral overload command is designed with STT and BTT hybrid control mode to meet the operational requirements of lateral large maneuver in cruise phase.Firstly,each constraint faced by the aspirated hypersonic missiles in order to meet the normal working conditions of the scramjet engine in the cruise phase is analyzed,then the STT and BTT hybrid control strategy on the premise of meeting the constraints is designed,and the cruise phase of the aspirated hypersonic missiles with overload three-loop autopilot is simulated.The simulation results show that the designed hybrid control strategy can improve the lateral overload capability of the aspirated hypersonic missiles.
