HIGH-EXPLOSIVE FRAGMENTATION PROJECTILE Russian patent published in 2003 - IPC

FIELD: ammunition, in particular, projectiles with unfolding blades of the tail assembly for aerodynamic axial stabilization after flying-out from the barrel. SUBSTANCE: the projectile has a body with obturating bands and an explosive filling, as well as a fuse and a body of the aerodynamic tailplane. Blades installed on the turn axles are laid in the radial slots of the tailplane. The front free ends of the blades are V- shaped and fixed by a tread ring installed on the tailplane body for longitudinal motion. Supporting bosses are made on the rear ends of the blades. The blades on the turn axles may be so installed that their rear end would be positioned in the radial slot of the tailplane body with a minimum clearance. EFFECT: enhanced functional reliability due to simplified construction of the aerodynamic tail assembly and the mechanism of automatic unfolding of the blades. 2 cl, 3 dwg
