Cooling device of artillery barrels

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to weapons, namely to devices for cooling of artillery barrels. Cooling device of artillery barrels arranged in shaft between projectile and propellant charge. Device has possibility of formation of thin sublimating cooling coating on inner surface of barrel during firing.

EFFECT: technical result consists in creation of effective cooling system of artillery barrel without making significant changes in its design.

FIELD: weapon and ammunition.

SUBSTANCE: cooling system consists of two tanks - larger and smaller - with cooling emulsion connected among themselves by the pipeline through the cooling tap. The smaller tank is located inside the fire control handle in the lower part of which the drain plug is located. In the smaller tank the cylinder with holes, the piston and the rubber ball inside the piston is located. The return spring of the piston is located around it in its top part above the small tank. The pipeline the top end of which is laid into the stock cartridge chamber is connected to the lower part of the cylinder. On the pipeline near the trigger the tap with a guidon connected by rod to the lower end of the trigger is installed. In case of use of a folding butt both tanks are connected with a flexible hose.

EFFECT: improving cooling efficiency of gun barrels in submachine guns, auto-machine guns, heavy-calibre machine guns and automatic cannons.

SUBSTANCE: invention refers to military equipment. A gun barrel cooling system has a barrel and a bolt. In addition, a piston compressor, either one-pass or two-pass, is installed, the piston-rod of which is connected in a movable manner with one of its ends to the bolt or to a bolt, and with its other end to a piston by means of a pin, and a receiver is connected to an outlet valve with the compressor cylinder; the receiver air line is directed to the barrel channel cartridge chamber.

EFFECT: improving cooling efficiency of gun barrels in submachine guns, auto-machine guns, heavy-calibre machine guns and automatic cannons.

SUBSTANCE: method for removing explosive gas from inhabited compartments of military tracked vehicles involves creation of air overpressure with a filtration ventilation plant and withdrawal of the air containing carbon monoxide from inhabited compartments through non-densities in the tank body. When an electric trigger of a coaxial machine gun (a gas source) is being pressed, a signal is supplied via electric wires through a time relay to an electric motor with an impeller, by putting it into operation. At rotation of the motor impeller, air underpressure is created through a one-sided valve in the isolated volume, where the coaxial machine gun (a gas source) is located. The air saturated with explosive gas is sucked out and gases are removed under pressure via a pipeline from isolated volume and inhabited compartments. Isolated volume is made from polymer or rubber-coated fabric or metal.

EFFECT: reduction of degree of content of explosive gas in inhabited compartments of tracked vehicles.

The invention relates to the field of military equipment and is aimed at improving an existing small arms, such as General purpose machine guns

SUBSTANCE: inner surface of the wellbore is coated with a thermionic material with up to 3 eV, that allows to align the wellbore temperature at its non-uniform heating and, hence, reduce the thermal bending in the wellbore.

EFFECT: increased reliability of the wellbore operation with the reduction of energy and material costs.
