METHOD FOR ASSEMBLING AN ARTILLERY CARTRIDGE Russian patent published in 2023 - IPC F42B5/02 F42B14/06 

FIELD: weaponry.

SUBSTANCE: method for coaxial assembly of an armor-piercing caliber reduced with a combustible case. An armor-piercing caliber reduced (1) of a artillery cartridge with a longitudinally composite bearing body having two caliber skirts (6) and (7) is coaxially jointed with a combustible cartridge case (2) equipped with a ball powder propellant, which is autonomously centered by placing the cartridge neck (2) on the shank of the bottom thickening (8) of the projectile body (1) through a layer of anaerobically hardening sealant in the coaxial joint of the cartridge neck (2) with the base shank of the bottom thickening (8) of the body for their monolithic fastening. The cartridge is assembled in a tool cylinder (3) conformal to the gun bore. The cartridge projectile is installed based on the caliber skirts (6) and (7), with the stop of the head thickening (5) on the jumper (4). The cartridge case (2) is centered by means of a production set of replaceable shell inserts (11) adjoining the tool cylinder (3) from the inside. The thickness of the shell inserts (11), starting from the smallest, is successively increased by a step - a quarter of the tolerance field for the diameter of the combustible case (2), determining the clearance between them is less than a step. The assembly is held until the layer of anaerobically cured sealant cures and the centering shell inserts are removed.

EFFECT: improvement of the method for single-sided support of a combustible case with a neck on the base shank of the body with ensuring their coaxiality is provided.
