针对目前弹道在线快速规划及制导方法的不足,充分借鉴离线弹道规划方法和拟平衡滑翔弹道在线规划方法的优点,并与跟踪制导方法相结合,提出了一种应用于滑翔飞行器的弹道在线快速规划方法及制导方法,有效提高了长时间滑翔飞行器大气层内飞行的自主性和灵活性。结果表明:弹道在线快速规划方法可以在弹载计算机上快速生成一条远程飞行轨迹,制导方法对规划出来的标准弹道的跟踪效果较好,适应偏差能力强。弹道在线快速规划及制导方法简单可靠、容易实现,具有较好的工程应用价值。

With regard to the limitation of the on-line trajectory design and guidance technology, utilizing the advantages of the off-line trajectory design, the quasi-equilibrium gliding trajectory design, and track- ing gliding, the on-line trajectory design and guidance technology are presented to be used in long-term endoatmospheric flight, which enhance the autonomy and the flexibility of the flight. The results show that the on-line trajectory design can generate a far trajectory very quickly with the missile-borne comput- er. And the standard trajectory is very appropriate for the guidance technology. In conclusion, the on- line trajectory design and guidance technology is simple and reliable, which has good engineering appliea-tion value.
