TANK CLUSTER PROJECTILE “VAVART” Russian patent published in 2018 - IPC F42B12/32 F42B12/58 

FIELD: weapons.

SUBSTANCE: invention relates to ammunition, and in particular to cluster projectiles with fragmentation warheads. Projectile contains a trajectory fuse with a pyrotechnic channel, a head fairing, a feather stabilizer and a set of spherical or close in shape to the sphere of fragmentation warheads. These elements are made in the form of a hollow housing with an explosive charge inside and a shock fuse. Fragmentation warheads have a diameter equal to the calibre of the projectile, and are equipped with two flat areas normal to the projectile longitudinal axis, and contacting to each other with said flat areas. In addition, the fragmentation warheads are made with cylindrical protrusions and depressions located diametrically opposite in the said areas and are interconnected using the disruptive pyrotechnic fastening elements. These elements are located on the said protrusions and depressions corresponding surfaces. Said pyrotechnic elements are configured to trigger with a delay in time, with simultaneous or sequential separation of the fragmentation warheads from each other. Feather stabilizer is fixed on the protrusion of the projectile's warhead last by flight element. Head fairing is installed by fixing in the depression of the first by flight warhead. In the place of their docking to each other warheads internal surface is made normal to the projectile longitudinal axis.

EFFECT: technical result is an increase in the cluster projectiles operation reliability due to the optimal use of their internal cavity.
