Abstract: For shaped weapons, once the characteristics of the warhead's drug mask, charge characteristics, and explosion distance and other factors are determined, the damage of this type of weapon mainly depends on its attack angle. The paper investigated the damage process and damage effect of shaped charge warhead of various attack angles using numerical simulation and model explosion test. The damage characteristics of shaped charge warhead subjecting to double-layer columniform shell were discussed. It can be concluded that, the smaller the attack angle, the larger the perforation diameter of shaped charge jet;The smaller the damage area, the stronger the load intension of unit area.
