HIGH-EXPLOSIVE FRAGMENTATION SHELL Russian patent published in 2019 - IPC F42B12/20 F42B12/32 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to high-explosive fragmentation and, in particular, to fragmentation-beam projectiles, which in the process of functioning simultaneously form axial and circular fields of damage. Shell consists of a body with an explosive charge, an aerodynamic fairing, a contact-trajectory fuse and a shank. Shank is made with a drop-down feathers. Projectile includes a screw head. It includes a fragmentation unit with a diaphragm resting on the front end of the body, and a pilot glass filled with an explosive. Splinter block is made in the form of rings tightly inserted into each other with semi-ready striking elements. These elements are formed by transverse and longitudinal grooves on the rings. Pilot glass and the diaphragm are made in one piece. Upper part of this part is connected to the screw head by means of a threaded connection. At the same time in the grooves on the rings are placed ready-made damaging elements from heavy metals. Screw head itself has superficial incisions.

EFFECT: increase the effectiveness of fragmentation of the projectile.
