摘要/Abstract

摘要： 为研究不同聚能装药水中冲击引爆靶后炸药的性能，选择爆炸成型弹丸（Explosively Formed Projectile, EFP）、杆式射流（Jetting Projectile Charge，JPC）、聚能射流（Shaped Charge Jet，JET）3种聚能装药结构，开展水中侵彻和水中冲击引爆试验，得到不同聚能装药侵彻体入水前、着靶前和穿靶后的实测速度及对弧形靶板的侵彻效果和对靶后B炸药冲击引爆效果，并对比分析不同聚能装药水中冲击引爆机理及其在不同水介质长度下的冲击起爆系数k值的变化规律。研究结果表明：随着水介质长度的增加，3种聚能装药在水中冲击引爆靶后炸药的性能均呈非线性减小变化，且JPC的性能优于JET和EFP；3种聚能装药在穿透0~100cm水介质长度和2cm厚度的金属靶板后隔水冲击引爆B炸药的临界冲击起爆系数为18.22 mm³/μs²。

Abstract: In order to study the performance of explosives after different shaped charge impact detonation targets in water, three kinds of shaped charge structures explosively formed projectile ( EFP ), jetting projectile charge ( JPC ), shaped charge jet( JET) were selected, and three kinds of shaped charge water penetration and water impact detonation tests were carried out. The measured velocities of different shaped charge penetrators before entering water, before hitting the target and after penetrating the target, the penetration effect on the arc target plate and the impact detonation effect on the B explosive behind the target were obtained. The impact initiation mechanism of different shaped charge in water and the variation law of impact initiation coefficient k under different water medium lengths are compared and analyzed. The results show that with the increase of the length of the water medium, the performance of the three kinds of shaped charge after impacting the detonation target in water decreases nonlinearly, and the performance of JPC is better than that of JET and EFP. The critical impact initiation coefficient of explosive B is 18.22 mm³/s² after three shaped charge penetrating the metal target plate with a length of 0-100cm water medium and a thickness of 2cm.

Key words: Shaped charge, penetration in water, water impact detonation, impact initiation constant, detonation threshold
