FIELD: weapons and ammunition.
SUBSTANCE: invention relates to automatic weapons. Automatic small-arms-artillery system comprises a rifled barrel with a bolt, mechanisms for supplying ammunition to the line of docking and ramming into the breech, a mechanism for opening and closing the bolt, a mechanism for producing the shot and a mechanism for extracting and removing the spent cartridges. Bore is straight. In order to give the projectile rotation during firing, the shaft is untwisted by the electromechanical drive to the required value. Projectile is also untwisted before revolutions equal to the barrel revolutions before feeding into the breech. Electromechanical drive is reversible, which makes it possible to impart rotation of barrel in different directions during service of barrel for uniform wear of guide surfaces of thread.
EFFECT: increased durability of shaft, reduced wear of drive mechanisms, simplified production.
