摘　　要：针对滑翔式飞行器的弹道特征,提出了一种方案弹道设计方法,将整个再入弹道分为下降段、滑翔段和末制导段,通过简化的控制指令实现下降段和末制导段弹道,并通过"H-V曲线设计+弹道跟踪"的方法来实现滑翔段的弹道设计,根据侧向运动要求调整侧倾角的变号时机,迭代得到完整的再入基准轨道。最后的算例表明,该方法能快速得到一条针对某一飞行任务的再入弹道。According to the character of reentry trajectory,a trajectory planning methodology was raised in which the reentry trajectory was divided into descent phase,glide phase and terminal phase.In descent phase and terminal phase,constant attack angle was employed.It glide phase,a combination of H-V flight profile design with trajectory tracking was proposed to obtain longitudinal reference trajectory,a ＂control point＂ was used to adjust the H-V flight profile,a constant bank angle was used to control lateral motion.The result shows that the trajectory planning methodology is rapid,rational and easy for implementation.
