Abstract
According to the calculations, the penetration effect of shaped charges can be significantly increased (by 40–50 % in the case of a high-strength steel target) if due increasing the accuracy of their manufacture the lower speed threshold is reduced at which the penetration of the tail sections of the shaped-charge jet into the target is stopped. For experimental confirmation of these data, it is proposed to study in detail the penetrability of the tail sections of shaped-charge jets using cut-off rods made of high-density material located at a short distance from the shaped charge (less than its diameter) and designed to eliminate the faster part of the jet. Based on numerical simulation in the framework of a two-dimensional axisymmetric problem of continuum mechanics, possible parameters of the cut-off rods for generating solitary "tails" of shaped-charge jets with different velocities of the leading element are predicted.
