针对水中序爆子弹拋撒后间距过小可能相互殉爆或影响工作性能的问题,通过陆上抛撒试验落点坐标数据统计分析,得到子弹抛撒后距离分布。不相邻子弹抛撒后距离均值多显著大于相邻子弹,且子弹层距越大,抛撒后两层子弹间距离均值也越大。据此进行了母弹内同层子弹和不同层间子弹装配时序优化排布,以有利于降低子弹抛撒后相互殉爆和因爆炸冲击引起的机械结构或电路失效的可能性,提高子弹正常工作概率。

Since short distance of submunition initiated in sequence under water may cause sympathetic detonation and affect its working ability, after analysis of data of a dispersal experiment, distance distribution of submunition was acquired.Specifically, mean value of distance of non-adjacent submunitions is greater than that of adjacent ones obviously, the greater the difference of tier number is, the greater distance of two submunitions is between two tiers.According to the conclusions above, better order arrangement of submunition in the same tier and among different tiers in cargo projectile was proposed.The new arrangement is beneficial to decrease the possibility of sympathetic detonation and damage of mechanical structure and circuit after dispersal, thus, increasing the probability of submunition working properly.
