Abstract

Abstract:

In order to improve the damage ability of shaped charge warhead,a kind of conical-spherical combined liner shaped charge warhead and a double-layers target plate with water interlayer are designed based on the initiation mechanism of combined liner shaped charge warhead. A physics model of warhead penetrating into the double-layers target plate with water interlayer is established, and is numerically simulated. According to the calculation results, a 1∶3 scale warhead prototype and a scaling equivalent target plate are made, then the test is finished, which is in favor of designing full-size warhead prototype. The result shows that the shaped charge warhead is propitious to damage the structure with water interlayer, which improving the damage effect to target.

Key words: shaped charge warhead, double-layers target plate with water interlayer, damage effect, combined liner
