影响子母弹终端效应的关键参数及其搜索方法

为解决航空子母弹抛撒点抛撒高度、速度等参数设定问题,基于一种子弹单圈多段排布的航空子母弹模型,通过建立子弹的外弹道方程,研究它的地面散布并且寻找其散布规律；然后根据在实战中要求的所要摧毁的目标形状、面积,从子母弹作战效能角度出发,提出一种搜索算法,用该算法能搜索出覆盖目标范围所要求的子母弹的几种抛撒参数.仿真验证表明:该算法能够使子弹有效地覆盖目标,最大误差2.5％,提高了航空子母弹的作战效能.

The Key Parameters Affecting the Longitudinal End Effect of the Shrapnel and the Search Method

In order to get the key parameters of the Projectile Point of the sub-warheads, the external trajectory equation of bullets is constructed and the rule of the cluster warhead''s fall point is analyzed based on a model of warhead with sub-warheads and the structure of excessive segments arrangement. This paper proceeds from the operational effectiveness, elects a search algorithm based on the shape and area of target. After simulation investigation, the use of this algorithm can ensure that the warheads effectively cover the whole area of the target, and the maximum error is only 2.5%. Therefore, the algorithm is efficient in improving the operational effectiveness of the shrapnel, and also can provide a new thought for the use and the development of the shrapnel.
