BLAST-FRAGMENTATION WARHEAD Russian patent published in 1999 - IPC

FIELD: military equipment, applicable in jet projectiles of salvo fire systems and in other blast-fragmentation ammunition. SUBSTANCE: the blast-fragmentation warhead has a body with a detachable bottom and uniformly contracting nose, explosive charge, layer of ready-made fragments, nose fuze with an initiating explosive charge located in the body; the warhead is furnished with a solid-state neodymium laser with a blast-stimulated charge of condensed explosive, hollow central tube, the central tube consists of sections separated by detonators with light-sensitive secondary explosive, having a central hole with a diameter equal to the inside diameter of the central tube and which are apart from one another at a distance equal to , where d-radius of warhead explosive charge, D - explosive detonating velocity, t₂= t_p-t₁, where t_p - time of shell destruction, t₁(d/2)/D - - time of passage of detonation wave from the point initiation to the shell lateral surface; t_p= t₁+t₂< τ, τ - - time of explosive activation. EFFECT: accumulation of maximum excessive pressure in the shock-wave front, as a result, enhanced efficiency of blast action of the warhead. 2 cl, 2 dwg
