SINGLE-SHOT CARTRIDGE FOR REMOTE MINING Russian patent published in 2024 - IPC F42B12/58 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition, namely to disposable cartridges for remote mining of terrain. Single-use cartridge for remote mining contains cylindrical barrel with self-destruction time setting unit, inside which a piston with an expelling charge and a unit containing two sections of multipurpose mines fixed in it are located coaxially with it, a disk with separating charges, which is divided into two parts, self-destruction time setting unit, pyrotechnic circuits, electric capsule. In one of the sections of the unit, the mines rest against the seats on the piston on one side, and on the other side—on the seats on one of the sides of the divided disc. In the other of the sections of the unit, the mines rest on the seats on the other side of the divided disc on one side, and on the other side—against the seats on the self-destruction time setting unit, located at the outlet hole of the sleeve. In the center of the cylindrical shell there is a gas duct tube made with the possibility of ensuring the unit with mines design unity, one end of which is fixed in the piston, and the other is in the self-destruction time installer. Gas duct tube consists of two parts connected by a bursting bushing in the center of a disk with separating charges being divided into two parts. Bushing with a central calibrated hole is installed at one end of the gas duct tube, under the expelling charge in the piston. At the other end of the gas duct tube there is a detachable plug, and in the gas duct tube there is an additional charge of powder to provide for two-mode throwing of the block with mines from the cartridge. Wiring harness is installed in tension with the use of a tension sleeve in the grooves of the external contour of the divided disk.

EFFECT: increased efficiency of minefield creation due to provision of uniform unpacking of cartridge.
