动态飞行下轴向预制破片飞散角数据处理方法

The Data Processing Method for the Scattering Angle of Axial Preformed Fragments under Dynamic Flight

为研究轴向预制破片飞散角数据处理方法,利用某型轴向预制破片战斗部具备设定爆炸距离及精确控制炸点的有利条件,设计了一种炮射弹药的动态飞行试验。通过获取动态飞行下轴向预制破片密度分布,结合静爆破片威力场处理方法,提出新的破片比率积分、破片平均密度和间断位置3种数据处理方法。根据破片密度分布结果,计算并对比3种数据处理方法得到的飞散角,并由此得出间断位置数据处理方法获取的飞散角以角度区间的并集形式能较为全面的表示出破片杀伤分布。3种数据处理方法及试验结果可为实弹条件下弹药威力和毁伤评估提供技术支持。

In order to study the data processing method for the scattering angle of axial preformed fragment,the warhead with a certain type of axial preformed fragment has the advantage of setting the explosion distance and accurately controlling the explosion point,so a dynamic-flying test of gun-launched method is designed.The density distribution of axial preformed fragments under dynamic flight is obtained.Combined with the data processing method of static test,the data processing method of ratio integral of fragment,the data processing method for average density of fragments and the data processing method for continuous location,three new data processing methods are proposed.Based on the density distribution of fragments,the scattering angles obtained by three new data processing methods are calculated and compared.It can be seen that the data processing method for continuous location can more comprehensive represent the damage distribution of fragments in the form of an interval of angles.The test results and data processing methods can be used for evaluation of ammunition power under actual combat scene.
