Abstract

A method for evaluating the penetrating (piercing) power of shaped charges under the condition when an intense electric current pulse is applied to a shaped charge jet is developed. The buildup of waist-type MHD instability and the volume damage of the jet material are viewed as possible mechanisms behind a reduction of the penetrating power of a shaped charge jet under the current action. With this method, electrodynamic action parameters that provide a significant reduction of the penetrating power of a shaped charge jet are calculated for shaped charges of various penetrability.
