双层含能药型罩K装药射流成型及侵彻性能试验

为提高含能材料形成射流对目标的侵彻深度,设计了一种基于K装药结构的Al/Ni?Cu双层含能药型罩聚能装药结构,其内层罩为无氧铜,外层罩为Al/Ni含能结构材料。分别开展了Al/Ni?Cu双层含能药型罩与Cu?Cu双层药型罩的聚能射流成型X光试验、侵彻钢锭静破甲试验和对典型混凝土靶标的侵彻威力试验。研究结果表明,双层含能药型罩K装药起爆后可形成连续射流,侵彻的钢靶和混凝土靶中有明显的开坑区形成,但射流对侵彻过程的扩孔作用不明显。Al/Ni?Cu双层含能药型罩可发挥动能和化学反应的联合侵彻毁伤效应,与Cu?Cu罩相比,在靶中形成射流堆积更少,对钢靶的侵彻深度和侵彻体积分别提高了20.1%和23.0%,对混凝土靶的侵彻深度和侵彻体积分别提高了17.2%和45.6%。

Experimental Study on Jet Formation and Penetration Performance of Double-layered Reactive Liners with K- Charge

To improve the penetration depth in the target subjected to the jet of reactive materials liner,a shaped charge with Al/Ni?Cu double?layered reactive liners based on the K?charge structure was proposed.The outer and inner liner of the double?layered reactive liner are made of oxygen?free copper and Al/lNi reactive material,respectively.Experimetal study of jet formation,static armor?piercing into steel ingots and the penetration power to typical concrete targets were carried out seperately by using X?ray cinematography.Results show that the double?layered reactive liners with K?charge can form a continuous jet after detonation with obvious pit areas in steel and concrete targets.However,the jet has no obvious reaming effect on penetrating the target.A combined damage effect of kinetic energy and chemical reaction can be achieved by the Al/Ni?Cu double?layered reactive liners.Compared with the Cu?Cu double?layered,less jet accumulated in the target penetrated by the new double?layered reactive linears.Meanwhile,the penetration depth and volume of the steel targets were increased by 20.1%and 23.0%,respectively,while the penetration depth and volume of the concrete targets were increased by 17.2%and 45.6%,respectively.
