METHOD OF FIRING LARGE-CALIBRE BARREL WEAPONS USING DUMMY CARTRIDGE AND DUMMY CARTRIDGE FOR ITS IMPLEMENTING Russian patent published in 2008 - IPC F42B8/10 F41A33/00 

FIELD: weapons.

SUBSTANCE: bullet from a live cartridge for smallarms of a smaller calibre is subject to a longitudinal acceleration, which is effectuated over the length of entering the bullet into a case, then powder gases and a portion of propellant charge that has not been burnt down are released into the atmosphere and the bullet is decelerated over the length of a rifled part of the barrel due to the force of friction between the bullet and the rifles to achieve a muzzle velocity for large-calibre barrel weapons. To this end said live cartridge for smallarms forms a gas-generator and a propelled body, whereby a projectile simulator is equipped with a projectile shell simulator for large-calibre barrel weapons. The simulators are attached to each other using a fire indestructible connection. A rifled barrel corresponding to a live smallarms cartridge and being open on its both sides is fixed along the centre line of the projectile and shell simulators. Around said barrel inside the projectile and shell simulators for large-calibre barrel weapons there is a free space connected via a perforation made in the rifled barrel on the edge of the live smallarms cartridge case to the space of the barrel and via a perforation made in the head of the projectile simulator - to the atmosphere.

EFFECT: cheapening the process of gunners training on retention of safety thereof.
