BLAST-FRAGMENTATION WARHEAD Russian patent published in 1999 - IPC

FIELD: military equipment, applicable in jet projectiles of salvo fire systems, artillery, aircraft and naval projectiles, as well as in other blast-fragmentation ammunition. SUBSTANCE: the blast-fragmentation warhead has a body with a uniformly contracting nose and bottom, cylinder-shaped explosive charge, layer of ready-made fragments and a nose fuze with a detonation tube located in the body. The explosive charge is made up of a set of n successively positioned explosive slabs; detonating velocity of explosive, each subsequent slab counting from the head slab at preset Di is determined from relation D_i+1= (1,1÷1,6)D_i, and the thickness of each slab is determined from relation ; where i=1,2,3,...n - slab number, a - explosive charge radius. The last slab has the shape of a hemisphere facing the bottom with the spherical surface, and the cavity between the last slab, body and bottom of the warhead is filled with explosive with a detonating velocity of at least 1.1 Dn. EFFECT: equalized godograph of velocities of divergence of fragments in charge length, as a result, enhanced efficiency of warhead fragmentation action. 2 cl, 1 dwg
