ANTI-CUMULATIVE MEANS OF PROTECTION OF EXPLOSIVE OBJECTS Russian patent published in 2021 - IPC F41H5/04 F41H7/04 

FIELD: means of explosion protection.

SUBSTANCE: anti-cumulative means of protection of explosive facilities is intended for protection of explosive materials and articles in vehicles, in case of impact of destructive elements of conventional weapons. Most dangerous elements of the conventional weapons are cumulative jets of the corresponding ammunition. This technical solution is further improvement of protection means using new principles of cumulative jet destruction, dispersion of jet fragments at penetration into obstacles and further neutralization (combustion) of cumulative jet in original material. In particular, to implement the principle of neutralization (combustion) of the cumulative jet, an additional layer of porous ceramic is used, pores of which are filled with chemically active filler, which is arranged between two thin-walled sheets, and layer thickness is 200 mm. In this layer cumulative jet is neutralized (burnt). Directly to the layer with porous ceramic there adjoins the second layer made of high-strength ceramics plates, for example, boron carbide, silicon carbide, aluminum oxide etc., wherein ceramic plates with thickness of 15...20 mm in this layer are also fixed in form of corrugation with angle at vertex 40...60 degrees between thin-walled sheets spaced at 80...100 mm. First layer adjoins the first layer consisting of deflecting elements in the form of frequent metal meshes of voluminous braiding. Upon penetration of the jet fragmented in the first layer into the ceramic layer in contact with the ceramic plates, the jet undergoes further deviation and is neutralized (burnt) in the layer of the porous ceramic with the chemically active filler. On transport, anti-cumulative means of explosive hazardous objects protection is fixed in the form of a wall assembled from separate modules.

EFFECT: as a result, the cumulative jet penetrating power is lost completely; thereby excluding excitation of explosive transformation in form of combustion or detonation in explosive material.
