FIELD: means of protection.
SUBSTANCE: protective device includes external (explosion-proof) and internal (bullet-proof) circuits. External circuit is made of metal grids in the form of curtains with gathers, and internal circuit includes steel screen and metal grid curtains with cell size not exceeding one bullet gauge. Both circuits are preengineered and mounted as separate modules including 1-3 grid curtain units in metal frames, or steel screens. Modules are fastened to each other, with external circuit curtains mounted in metal racks tilted at 45-60° towards the curtains at both sides in fishbone pattern, and internal circuit curtains fixated at inner side of rack. Curtains are made of elastic grid with spatial lattice.
EFFECT: reduced metal consumption, reliable triggering of hollow-charge grenade in external circuit, intensive dispersion of explosive jet in air, simplified installation and disassembly, enhanced total efficiency of protective device.
