云爆战斗部终点状态对地面反射压的影响试验研究

Experimental Study on the Influence of FAE Warhead Terminal State on Ground Reflected Pressure

为掌握云爆战斗部终点状态对地面反射压的影响,采用模拟试验方法,获取了不同落角、云团炸高和二次起爆位置的云爆装置地面反射压的数据,分析了不同工况下的压力分布特性。结果表明,战斗部落角越大,地面反射压越高,压力场分布越均匀,90°落角地面反射压最大。云团炸高影响云雾区内外地面反射压的大小,存在最佳炸高,使得压力场最优。随着二次起爆装置在云雾区垂向距离和径向距离的增加,地面反射压呈先增大后减小的趋势。

In order to master the influence of FAE warhead terminal state on the ground reflection pressure,the ground reflection pressure date of the FAE device with different angular,bursting height of cloud and second detonating position were obtained by simulation experiment,and the pressure distribution characteristics under different working conditions were analyzed.The results show that the larger the warhead angular is,the higher the ground reflection pressure is,and the distribution of pressure field is about uniform,at the angular of 90 degrees,the ground reflection pressure is the highest;the cloud burst height affects the ground reflection pressure inside and outside the cloud area,and there is an optimal burst height,which makes the pressure field optimal;with the increase of vertical distance and radial distance of the second detonating device,the ground reflection pressure first increases and then decreases.
