    摘要:

    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%。

    Abstract:

    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.
