HIGH-EXPLOSIVE FRAGMENTATION SHELL Russian patent published in 2014 - IPC F42B12/20 F42B12/32 

FIELD: weapons and ammunition.

SUBSTANCE: invention refers to ammunition, and namely to high-explosive fragmentation shells for tank cannons with stabiliser blades that open after a shell leaves a barrel. A high-explosive fragmentation shell includes a housing, a nose fuze, an explosive charge, a tail aerodynamic stabiliser and a drive device. Blades mounted on turning axes are laid in radial slots of the stabiliser. An explosive charge consists of a central primary explosive charge and an additional peripheral charge, which are coaxially arranged. Peripheral charge has detonation speed decreased by 2-5 times in comparison to that of primary charge. Peripheral charge weight is not more than 5 wt % of primary charge weight. The drive device is made mainly from polymer. The drive device is connected to the shell housing by means of annular projections and installed on the stabiliser with possibility of protection of blades at movement of the shell during an internal ballistic cycle. The drive device has through longitudinal slots on the side of its front part at the length comprising 0.2-0.4 of its total length.

EFFECT: improving efficiency of high-explosive fragmentation action of ammunition.
