Background
The charge of the anti-diving warhead is mainly divided into shaped charge and blasting charge. The blasting charge damages a target by using an underwater blasting effect, and the energy-gathered charge has an energy-gathered penetration effect besides the underwater blasting effect. For the damage of the hull structure, the explosion effect can cause the deformation of the cabin shell and even the tearing of the shell, and the energy-gathering effect can generate the energy-gathering penetration body to cause the energy-gathering perforation damage of the shell.
At present, the energy-gathering type anti-diving warhead is evaluated at home and abroad mainly by a ground static explosion test method according to the perforation aperture of the target plate penetrated by the warhead and the number of the penetrated target plates. The method only examines the energy-gathering effect, cannot examine the blasting effect and cannot truly reflect the actual underwater damage capability of the warhead.
In addition, the destructive effects on the housing may be different for different types of warheads, i.e., one or more destructive effect characteristics of cumulative perforation, deformation, or tearing lacerations may occur.
