| 摘 要： | 针对升力体飞行器滑翔再入的飞行特点,提出基于动压剖面的再入弹道解析方法.首先,推导基于动压和高度历程的质点动力学方程,并给出已知动压剖面求弹道的解析算法.其次,根据飞行任务把滑翔再入过程分成初始下滑段和准平衡滑翔段,通过动压规划设计准平衡滑翔段弹道.最后仿真表明基于动压剖面的弹道设计方法能满足滑翔再入的飞行任务和飞行约束.

| Abstract: | An analytic trajectory solution based on dynamic pressure planning is presented for the gliding reentry of lift-body. Firstly,the equations of motion are transformed from velocity to dynamic pressure and from time to altitude. An analytic method is proposed to calculate the trajectory parameters on condition of the dynamic pressure. Secondly,according to flight task the gliding reentry is divided by initial descent and equilibrium glide. The dynamic pressure of equilibrium glide is scheduled and the geometr... |
