HIGH-EXPLOSIVE FRAGMENTATION SHELL Russian patent published in 2019 - IPC F42B12/20 

FIELD: weapons.

SUBSTANCE: invention relates to military equipment, namely, to fragmentation-explosive shells for firing artillery pieces. High-explosive fragmentation shell consists of housing with driving belt, main charge explosive, adapter sleeve with explosive cartridge. On the cylindrical part of the body, a thickening is made in front of the driving band at distance of 0.5–1.5 of the projectile caliber from the driving band from the housing material with the possibility of being cut into the barrel channel cuts. Diameter of this thickening exceeds caliber of the barrel and is smaller than the diameter of the barrel along the notches. At that, the adapter sleeve is made from an explosive with density different from that of the main projectile explosive. Bottom cone is arranged at stern rear part.

EFFECT: technical result is higher reliability of device due to free-motion motion of projectile along barrel channel with improvement of combative combat and reduced bottom resistance.
