滑翔增程弹滑翔段弹道设计

Gliding Trajectory Design of Gliding Extended Range Projectile

通过分析滑翔增程弹滑翔原理,建立弹箭滑翔弹道方程,对最大升阻比情况下的马赫数和攻角进行函数拟合,通过Matlab进行求解得到优化弹道,进而得出弹箭滑翔段优化后攻角随时间的变化曲线。文中针对某型滑翔增程弹进行优化弹道的仿真计算并与理想直线滑翔进行比较,结果表明增程效果明显,对弹箭滑翔段的弹道设计具有一定的参考意义。

The gliding trajectory equation of projectiles and rockets are established by analysis of gliding theory of gli- ding extended range projectile. The function fitting of angle of attack in case of optimal trajectory is obtained by using Matlab software, and the variation curve of attack versus time optimization of gliding trajectory. In this paper, the simulation calcula- tion of trajectory optimization for a certain type of gliding extended range projectile is proceeded and is compared with the ide- al gliding straight line. The result shows that the extended range effect is obvious, and it offers a reference for gliding trajec- tory design of projectiles and rockets.
