虚拟导引方法在再入滑翔弹道优化中的应用研究

针对飞行器再入大气层后的滑翔弹道，建立了飞行动力学模型，采用设置虚拟目标的导引方法进行优化。提出了几种调控弹道形式和射程的途径，并结合具体算例进行了弹道仿真，具体分析了虚拟目标位置、比例导引系数、攻角等参数对弹道弯曲程度、过载、热流、射程等方面的影响规律，说明综合考虑这些因素可得到理想的弹道优化的结果。

Research on application of virtual guidance to the trajectory optimization of reentry-glide flight

A fly dynamics model is established in accordance with the reentry-glide fight in this paper, and the method of virtual guidance is adopted to the trajectory optimization. Some approaches is proposed to modulate and control the trajectory form and range. A simulating example is presented. The effects of virtual target, guidance coefficient and attack angle on trajectory form, overloading and range are analyzed particularly. The results show that trajectory can be optimized effectively by synthetically consi...
