Description

Field of technology

The utility model refers to an explosive system, which is an article that is an anti-ship mine designed to disrupt the integrity of rigid barriers by forming a monolithic impact body (core) with high kinetic energy.

BACKGROUND OF THE INVENTION

Known and used in practice is such an explosive system, forming a monolithic core, consisting of the following elements: housing, lining, explosive and detonator (Fig. 1a).

The body is made of low carbon steel, the lining is a hemispherical segment of plastic metal. The explosive is two-component and is placed in the housing by the casting method. The detonator is mounted in the center of the lower part of the housing.

A disadvantage of the described construction is the large diameter of the hemispherical segment. This leads to insufficient deformation (shrinkage) of the monolithic core. The large cross section is the reason for the rapid drop in velocity, and hence the loss of kinetic energy. Known and used in practice is a system forming a monolithic impact core, consisting of a housing, an explosive lining and a detonator (Fig. 16).

A disadvantage of the described system is the very thin wall of the housing. This fact leads to the formation of a shock core with a large diameter and a coefficient of air resistance with a higher value.

Known and used in practice is an explosive system, which contains a lining bent to <2a less than 120 ° (Fig. 1c).

The disadvantage of the described system is the smaller <2a. This feature is a prerequisite for both irregular plastic deformation and deviation of the core from the direction of movement.
