Performance test and application of the multi-point ring initiator for a shaped charge

A series of experiments were conducted to investigate the synchrony of the multi-point ring initiator applied to a shaped charge and the penetration capability of the shaped charges with the multi-point ring initiators into reinforced concrete targets. The output synchrony of all points of the multi-point ring initiator was measured by using the high-speed photography and fiber probe technique. It is showed that the output synchrony of all points is good and the longest time difference is less than 0.1 μs. The shaped charges were initiated to penetrate into reinforced concrete targets by applying the multi-point ring initiators and the central point initiation, respectively. Comparison of the experimental results shows that the multi-point ring initiators can improve markedly the penetration capability of the shaped charges.
