DEVICE FOR PERFORATION OF PROTECTIVE WALLS

摘要

FIELD: weapons.;SUBSTANCE: invention relates to devices for perforation of protective walls, for example, to fragmentation ammunition with equipment of striking elements (hereinafter SE) of rational shape. More specifically, to combat charges, housing of which has fragmentation shell with external attenuating notch for formation of semi-finished SE, or fragmentation shell containing ready SE of proposed rational form. Device for perforation of protective walls consists of an explosive (hereinafter referred to as explosive substance ES), an initiator and a fragmentation shell made in the form of a set of ready SE laid around the explosives, or semi-finished SE. Prefabricated or semi-finished SE are made differently thick enough to enable turning of SE in process of device operation from smaller thickness to larger and formation of fragmentation field of required direction in compliance with direction of turn, for which the difference in thickness of the SE is formed by linear law when performing the section or part of the section facing the ES, quasi-flat, wherein length of SE in direction of variation of thickness is not less than maximum thickness of SE, and fragmentation shell is made completely or partially from different-thickness SE.;EFFECT: technical result consists in improvement of protective walls perforation and expansion of SE impact area.;1 cl, 6 dwg
