GRENADE TESTING RIG Russian patent published in 2017 - IPC F42B35/00 

FIELD: weapons and ammunition.

SUBSTANCE: grenade testing rig contains a gas generator formed by a cartridge chamber with the light weapon blank cartridge installed in it, a pressed breechblock with a cartridge trigger, an intermediate chamber between a barrel and the cartridge chamber, the smooth or rifled barrel installed with provision of pressing of the leading band of a grenade to the end of its guiding part by a shell simulator, a forcing unit, which is located between the intermediate chamber and the cartridge chamber, for blank cartridge charge and holes of a gas-dynamic link between the intermediate chamber and the barrel. The forcing unit for the blank cartridge charge is formed by the indestructible curtain adjoining to the cartridge chamber equally centered towards it and equipped by an axial projection located in the cartridge chamber, orifices performed on the perimeter of the curtain, and radial notches on its end performed from the axial projection to each orifice. Whereupon, the orifices are shifted relatively to the holes of the gas-dynamic link between the intermediate chamber and the barrel in the radial or circular directions, and the axial projection is performed with the diameter less than the cartridge neck bore opened.
