CARTRIDGE Russian patent published in 2012 - IPC F42B5/02 F42B12/02 

FIELD: weapons and ammunition.

SUBSTANCE: cartridge comprises a case and a shell. The cartridge is fixed to the shell by a link damaged in process of firing. The shell comprises a thin-walled jacket with a full charge, a plastic cover, an explosive device with a detonator and an orifice. The plastic cover is made in the form of a sleeve with a lead belt shaped on it. In the cover cavity there is an insert available that fills it and is not damaged during firing with a dead axial cavity at the side of the full charge. In the dead axial cavity there is an explosive device installed. The explosive device detonator is placed in an end groove arranged in the full charge. The orifice is installed between the cover and the full charge and has external diameter equal to the full charge diameter. The orifice is made with thickness providing for its arrangement between the front end of the explosive device case and the charge of its detonator. The orifice comprises an axial hole. The hole in the orifice is made with a diameter that provides for its installation onto the explosive device detonator as free fitted. The cover, the insert, the case of the explosive device and the orifice form a pressure mass, reciprocal energy of which during firing at minimum distance is equal or close to energy acting at it during full charge explosion.

EFFECT: higher reliability of shell full charge actuation.
