高超声速滑翔飞行器再入段制导方法综述

Review of reentry guidance methods for hypersonic gliding vehicles

针对高超声速滑翔飞行器再入飞行段,回顾了制导技术的发展历程和研究现状。建立了高超声速滑翔飞行器运动模型,并分析了再入段的路径约束、终端约束和地理约束。将再入制导方法分为三类:标准轨迹制导方法、预测—校正制导方法、混合制导方法,分别对研究现状进行了综述。然后,专门针对侧向平面制导方法进行了讨论和分类,根据飞行任务不同分为了常规约束的制导问题与附加地理约束的制导问题两类。最后,对再入制导方法进行了总结,并结合未来高超声速滑翔飞行器的任务需求,展望了再入制导技术的发展方向。

The development of reentry guidance methods for hypersonic gliding vehicles was reviewed. Firstly, the dynamics of a reentry vehicle was established. The path constraints, the terminal constraints and the geographic constraints were analyzed for a reentry flight. Secondly, longitudinal reentry guidance algorithms were divided into three categories, the trajectory tracking method, the predictor-corrector method, and the hybrid method. Lateral reentry guidance algorithms were divided into two categories, guidance for the conventional constraints and guidance for the geographic constraints. Reviews were presented for the three longitudinal guidance methods and the two lateral guidance methods. Finally, the guidance technology was prospected for hypersonic gliding vehicles according to flight missions in the future.
