ARTILLERY-SHOOTING SYSTEM FOR INCREASING THROWING EFFICIENCY, METHODS OF THROWING AND TWISTING THROWN OBJECT Russian patent published in 2024 - IPC F41A21/32 F42B14/06 

FIELD: weapons.

SUBSTANCE: group of inventions relates to military equipment, in particular to artillery pieces and methods of firing. Artillery-shooting complex comprises a barrel equipped with a gas-dynamic muzzle device to swirl the object to be thrown. Thrown object is made in the form of drive tray assembly, which is equipped with impeller with longitudinal ribs, in axial channel of which there is a bushing with a projectile, a striker, an impact blasting charge. Throwing is organized by the drive tray assembly shot from the gun with the usual propellant charge, and on external ballistic trajectory, blasting charge is detonated, which gives additional acceleration to subcaliber armour-piercing projectile. For gyroscopic stabilization of the projectile, a twisting muzzle device is used, the barrel of which is equipped with at least two external gas channels connecting inlet and outlet openings in each channel. Opposite outlet openings there are exhaust openings, besides, outlet and exhaust openings are located tangentially to the barrel channel opposite to each other. Inlet openings are located behind outlet openings at a distance sufficient for synchronization of movement of jets of propellant gases between outlet and exhaust openings with the moment when the impeller of the thrown object passes by them. For firing from hand-held firearms, the bullet and the impeller are made detachable after the shot, wherein the impeller is installed behind the bullet, during overcoming of the swirling muzzle device, the impeller with the bullet is spun with cross tangential jets of propellant gases, then they are brought to external ballistic trajectory, tracer or incendiary charge is ignited, gases of which push the impeller out of the thrown object.

EFFECT: higher linear and peripheral velocities, higher efficiency of fire.
