Experimental Study on Underwater Explosion Damage Power of Warhead with Different Energy Output Configuration

Explosion damage power of underwater weapon warhead to large surface ship depends on action range, as well as action location, warhead charge variety, and detonation mode. In order to obtain the best position for attacking warhead of a large surface ship and the design criteria of charge and detonation modes, this study chose the warhead with typical explosive type and typical detonation mode to test the power field parameters in all directions of underwater explosion and the response of simulated ship target to bottom explosion of a typical warhead. The output law of underwater explosion energy of a warhead with different energy output configuration and the damage law to ship target were obtained. It is concluded that the explosive with high total energy and high bubble energy is suitable for the underwater weapon warhead; bottom attack and directional detonation can converge energy upward to obtain the best damage effect. This study may provide a reference for overall design of the underwater weapon warhead for attacking large surface ship.
