FIELD: weapons and ammunition.
SUBSTANCE: artillery barrel with universal external cooling utilises mechanical energy of barrel recoil when firing, driving a device comprising corrugated air and hydraulic cylinders and springs, which provides for extrusion and forced convection of a liquid coolant from the left bed into a detachable jacket of forced liquid cooling of the barrel at the side of a muzzle end with further discharge into the initial corrugated volume in the left bed. The device pumps air into a balloon in the left bed with its further distribution to blow the barrel after each shot, and to blow the detachable jacket of forced liquid cooling upon completion of field or mock firing. It is possible to use the right bed with arrangement of the same volumes in it for air and liquid.
EFFECT: higher reliability, persistence and combat effectiveness of barrel artillery.
