Operation of shaped charges with copper hemispherical liners of degressive (decreasing from top to bottom) thickness is experimentally studied. The velocity of the head of generated shaped-charge jets is determined along with how deep they penetrate a type-setting target made of steel disks and the sizes of holes made in the disks. The experimental data on an increase in the velocity and a decrease in the mass of the heads of shaped-charge jets, which occur with an increase in the difference in the thicknesses of the hemispherical liner at the apex and at the base are in good agreement with the results of numerical simulation carried out within the framework of a two-dimensional axisymmetric problem of continuous mechanics. According to the experimental results, the effect of technological manufacturing errors on the operation of these charges becomes stronger, which eliminates or significantly limits the increase in the penetrating action. In one of the versions of liners of degressive thickness, the depth of penetration of a target, which is average in two tests, increases by 7.5% as compared to the liner of constant thickness.

具有递减厚度的半球衬里的异型装药操作的计算和实验研究

实验研究了具有递减（从上到下递减）厚度的铜半球衬里的聚能装药的操作。产生的聚能射流的头部速度取决于它们穿透由钢盘制成的排版目标的深度以及盘中孔的大小。关于聚能射流射流速度增加和头部质量减少的实验数据，随着顶部和底部半球衬里厚度差异的增加而发生的实验数据非常吻合在连续力学的二维轴对称问题的框架内进行数值模拟的结果。根据实验结果，技术制造错误对这些装药操作的影响变得更强，从而消除或显着限制了穿透作用的增加。在厚度递减的衬垫版本之一中，与恒定厚度的衬垫相比，目标的穿透深度（在两次测试中是平均值）增加了 7.5%。
