云爆战斗部动态条件下云爆剂抛撒云团形态研究

Research on Cloud Shape of Fuel Air Explosive Warhead Under Dynamic Dispersion

为了掌握云爆弹在动态飞行条件下云爆剂抛撒的特性,基于仿真分析和动态抛撒试验,获取了动态条件下云爆剂抛撒云团的成长过程及形成规律。结果表明,云爆战斗部静态抛撒时,云团的形态呈扁平形,随着云爆战斗部运动速度的增加,云团的形态逐渐由扁平形向喇叭形发展,速度越高,喇叭形的开口越小,仿真分析可为云爆战斗部动态抛撒云团的形态预估提供方法。

In order to master the dispersion properties of fuel air explosive projectile in flight, based on the simulation analysis and dynamic dispersion experiment, the fuel air explosive cloud forming process and rule were obtained under dynamic dispersion. The results show that cloud shape become flat under static dispersion, while it changes form flat to horn with speed increasing of fuel air explosive warhead. The horn-mouth is narrowed when fuel air explosive warhead speeds up. The simulation analysis can provide a prediction method for the cloud shape under dynamic dispersion.
