SHAPED-CHARGE WARHEAD Russian patent published in 2004 - IPC

FIELD: designing of rocket shaped-charge warheads.

SUBSTANCE: the shaped-charge warhead has a body with a bottom, inert insert, main charge with a detonation impulse booster and a transfer charge, whose diameter equals the maximum diameter of the inert insert, located in the cavity between the warhead bottom and the inert insert, blasting device installed coaxially on the outer wall of the warhead bottom, with an electric detonator in the central bush, the ignition duct of the detonator in the blasting device is shut off by a spring-loaded shutter, whose transfer hole is made tapered, whose larger diameter faces the detonator and makes up 1.05 to 1.2 of the diameter of the latter, the detonation impulse booster is made in the form of a blasting cartridge of a high-power compound, positioned without any clearance in the aligned cylindrical undercutting of the warhead bottom facing the transfer hole of the blasting device shutter, and coupled to the transfer charge by an axisymmetric channel filled with the same compound as the transfer charge, the channel diameter makes up 3 to 3.5 of the critical diameter of the transfer charge explosive, and the booster cartridge diameter - 2 to 2.5 of the channel diameter.

EFFECT: enhanced armor-piercing capacity of the shaped-charge warhead due to organization of reliable initiation of the main charge by compensation of the axial errors of the firing circuit of the initiation unit components, with their minimum dimensions remaining unchanged.
