Influence of Eccentric Initiation on Torpedo Directional Warhead Power:

Directional initiation technology can increase the power utilization ratio of directional warhead for a torpedo, and enhance the damage to large ship target. In this study, numerical simulation and experiment were conducted to investigate the shock wave overpressure of the scale-reduced prototype of heavyweight torpedo directional warhead at same testing point in three different initiation ways. The results show that in certain distance range, the 3-point eccentric initiation of the warhead generates higher shock wave overpressure in the direction of target than central initiation, and the shock wave overpressure increases significantly with the increase in eccentricity. Therefore, the 3-point eccentric initiation becomes the preferential initiation way for heavyweight torpedo directional warhead. This research may provide a reference for optimization design of heavyweight torpedo directional warhead
