为了提高高超声速滑翔飞行器机动突防能力,本文研究了飞行器典型机动弹道的设计方法。首先,推导了高精度的高度-速度解析解,作为纵向弹道设计的基础。其次,基于高程解析解和横程解析解,设计了纵向机动模式和横向机动模式,实现飞行器纵向跳跃机动和横向摆动机动,分析了这两种模式对飞行器过载的影响,为实际突防中机动模式的选择提供依据;通过合理设计横向机动模式和纵向机动模式中弹道的幅值、频率和相位,实现飞行器空间螺旋机动和空间钟摆机动。最后,通过仿真验证了本文机动弹道设计方法具有较高精度,可满足实际突防设计的需求。

This study delves into the design methodology for typical maneuvering trajectories to enhance the maneuver penetration capability of hypersonic glide vehicles.Firstly,a high-precision altitude-velocity analytical solution was derived and used as the foundation for longitudinal trajectory designing.Secondly,based on the altitude and crossrange analytical solutions,longitudinal and lateral maneuver modes were devised to execute longitudinal skip and lateral weaving maneuvers.The effects of these modes on the vehicle's overload were analyzed,providing a basis for the choice of maneuver mode in the practical penetration.By meticulously designing the amplitude,frequency,and phase of trajectories in both longitudinal and lateral maneuver modes,spatial spiral and pendulum maneuvers were acquired.Finally,the effectiveness of the maneuver trajectory design method was simulated and verified,presenting high accuracy and meeting penetration requirements.
