摘要
The present invention pertains to rifle-bore small arms weapons, and more particularly to improvements in performance of rifle-bore small arms weapons. Though, it can find application in artillery as well. Technical result of the present invention is: increase in muzzle velocity of a bullet (8) in a rifle-bore weapon without changing the bore, the barrel length, the gunpowder charge mass, and the bullet mass; decrease in recoil of a weapon and loudness of- discharge and increase in battle close -grouping. Essence of the present invention is migration of the compressed air 'ballistic wave' into the rear space of the projectile (8) through grooves (5) or gaps (6) made in the walls of the barrel channel in the discharging process, and, thereby, increase in the resultant force imparting the translational motion to. the bullet (8) in. the barrel channel of the. weapon at the expense of decrease in the head resistance of the air, retardation of the pressure drop in the rear space of the projectile, and decrease in the friction force between the bullet (8) and the wall of the barrel channel.
