Research on Self-Adaption Dispersal Altitude Selection of Cluster Munition with High Rotation

针对高速旋转子母弹定时开舱后子弹药落点散布精度低的问题,提出一种修正开舱高度的自适应技术.建立了高速旋转子母弹子弹药全弹道模型,针对母弹发射时的初速误差、射角误差及抛撒高度误差,利用计算机对子弹药落点精度进行了仿真分析.结合分析结果提出一种基于开舱高度修正的母弹自适应技术以提高子弹药落点精度,并推导出适合高速旋转子母弹的开舱高度修正公式.

In order to solve the problem of low accuracy of submunitions dispersed from high rotation cluster munition with time fuse, a new self-adaption method based on dispersing altitude compensation was presented. A trajectory model of cluster munition with high rotation was developed. Then according to the error resulted from initial velocity, shooting angle and dispersing altitude, the impact dispersion of subminution was simulated. With the help of simulation result, a cluster munition self-adaption opening plan was proposed to improve the accuracy of impact points of submunitions based on dispersing altitude compensation. At last, a dispersal altitude compensation formula adapting to cluster munition with high rotation was deduced.
