滑翔增程弹弹道特性分析

滑翔增程是目前采用的较为有效的ー种弹箭增程技术。阐述了滑翔增程弹的飞行过 程，按其飞行过程将整个飞行弹道分为三段，并分别建立了各段的弹道模型；研究了整个飞行弹道 的特性，得到滑翔弹弹道与常规弹道在升弧段是一致的，在降弧段上则出现了较大的差別；在滚控 段采用“小步走”的控制策略，在滑控段采用开环控制。仿真计算表明：控制方法可行，计算结果与 设计思想一致，对滑翔增程弹的研制有一定的参考意义。滑翔增程是目前采用的较为有效的ー种弹箭增程技术。阐述了滑翔增程弹的飞行过 程，按其飞行过程将整个飞行弹道分为三段，并分别建立了各段的弹道模型；研究了整个飞行弹道 的特性，得到滑翔弹弹道与常规弹道在升弧段是一致的，在降弧段上则出现了较大的差別；在滚控 段采用“小步走”的控制策略，在滑控段采用开环控制。仿真计算表明：控制方法可行，计算结果与 设计思想一致，对滑翔增程弹的研制有一定的参考意义。

Analysis on the Ballistic Characteristics of Gliding Extended Range Projectile

The gliding flight of projectile is an efficient extended range technique.The flight process of gliding extended range projectile was explained.The whole flight trajectory was divided into three segments and the ballistic model of every segment was established.The characteristics of the whole flight trajectory were studied.The result shows that the characteristics of climbing trajectory are same,while the characteristics of falling trajectory have obvious difference between gliding trajectory and ordinary trajectory.The control strategy of "little step walk" is adopted in rolling control segment and the open loop control is used in gliding control segment.The simulative results show that the control method is feasible and the conclusion is the same as the designed ideas.It can be used for the design of gliding extended range projectile in the future.
