远程制导炮弹有控段弹道优化设计

Optimization Design of Control Phase Trajectory About Extended Range Guided Projectile

文中对某远程制导炮弹进行弹道优化设计,为了能够很好的控制炮弹飞行,将有控段分成滑翔段、增速段和过重补偿段进行研究。根据制导炮弹滑翔段的特点,建立了制导炮弹的弹道模型,然后根据所建立的模型,给出了一种基于滑翔段的弹道优化算法。该算法避免了繁杂的梯度计算,相对于序列二次规划法其计算量大大降低了。仿真结果表明,所设计的弹道方案不仅增大了弹丸的射程,也提高了弹丸的命中概率。

Some extended range guided projectile trajectory is best designed by this paper,In order to can control projectile flying path,the control phase was separate into sliding phase,accelerating phase and compensation over gravity phase go on research. According to the characteristic of guided projectile sliding phase,the exterior trajectory model was established,then give out a traj- ectory optimization arithmetic about gliding phase.The arithmetic need not go multifarious grads calculation,the calculation time much lesser to sequence quadratic programming algorithm.The simulation result indicate that the scheme of trajectory not only improve the projectile range,but also advance the projectile hit probability.
