带壳装药水中殉爆特性分析

Experiments of Sympathetic Detonation Performance of Explosives with Shell in Water

为了研究弹药在水下爆炸作用下的安全性,利用水下爆炸试验研究了2种铝壳装药的水中殉爆特性,确定了装药的殉爆距离和殉爆安全距离,并基于气泡能分析了被发装药的殉爆反应程度。结果表明:主发装药为1.5 mm铝壳的PBX装药,被发装药为1.0 mm铝壳的RS211装药时,殉爆距离约为60 mm,殉爆安全距离约为120 mm;主发装药为1.5 mm铝壳的PBX装药,被发装药为1.0 mm铝壳的PBX装药时,殉爆距离约为10 mm,殉爆安全距离约为30 mm。被发装药完全爆轰时,计算得到其反应率在86%~95%之间,这是由于2个气泡的融合导致气泡周期变小。

To investigate the safety of ammunition under underwater explosion,underwater sympathetic detonation characteristics of two types of explosives with aluminum shell are investigated via an underwater explosion test.The sympathetic detonation distance and safety distance of the test charges are determined,and the sympathetic reaction degree of the charge is analyzed based on the bubble energy.Results reveal that when the donor charge is a PBX charge with a 1.5 mm aluminum shell and the acceptor charge is an RS211 charge with a 1.0 mm aluminum shell,the sympathetic detonation distance is 60 mm and the safety distance of sympathetic detonation is 120 mm.When the donor and acceptor charges are PBX charges with 1.5 and 1.0 mm aluminum shells,respectively,the sympathetic detonation distance is 10 mm and the safety distance of sympathetic detonation is 30 mm.The reaction rates of completely detonated acceptor charges are only between 86%and 95%owing to a decrease in the bubble period caused by the fusion and collision of two bubbles.
