Abstract

FIELD: weapons and ammunition.

SUBSTANCE: method of removing powder gases from breech piece of tank armament involves the following: when armament electric trigger is pressed, the signal is transmitted by electric wires to timing relay and to actuating element. The first check valve is opened, air is bled off from air system bottle by pipeline, impeller is rotated thus generating rarefaction of air in breech zone. Air gassy with powder gases is forced to casing, and through impeller and the second check valve it is removed from armament breech piece by pipeline.

EFFECT: reducing level of powder gases pollution of fighting chamber.

Description

The invention relates to the field of military equipment, in particular to methods for reducing the gas contamination of the fighting compartment of a tank by powder gases, the source of which is its armament.

There is a method of reducing the gas contamination of the military compartment of a military tracked vehicle when the removal of powder gases is carried out by an exhaust ventilation system with a fan inside the inhabited compartments (see Technical Description: Landing Combat Vehicle (BMD-1). Military Publishing House of the USSR Ministry of Defense, 1973, p. 390, 392 Open Edition).

In addition, there is a known method of removing powder gases from the breech of a tank weapon for a T-72A tank, which consists in the fact that the filter-ventilation unit provides the supply of purified air to the fighting compartment and the control compartment of the machine and creates excessive pressure (back-up) in them, and also implements ventilation of these compartments, thereby reducing gas contamination when firing from a cannon and machine gun (see Technical description and operating instructions for the T-72A tank, book two, part two. Military Publishing House of the Ministry of Defense of the USSR, 1989 g., s.118. Open edition. Prototype).

The known method of removing powder gases from the breech of tank weapons allows you to create air pressure in the habitable compartments and partially reduce the overall level of gas contamination by powder gases. However, this method does not allow full ventilation of the inhabited compartments, in particular the fighting compartment, in the area of the breech of the tank gun when firing from it, to reduce the maximum permissible concentration of carbon monoxide to a safe value, as a result of which failure (death) may occur crew.

The objective of the present invention is to remove powder gases during firing from the breech zone of the tank gun located in the fighting compartment of the tank, a general reduction in the level of maximum permissible concentration of powder gases that appear when using weapons.

The technical result of the proposed invention is the removal of powder gases from the breech zone of the tank gun, which contains the highest concentration of powder gases, without the consumption of electricity, reducing the overall level of gas contamination of both the fighting compartment and the control compartment.

The technical solution of the proposed invention is the use of the impeller, automatically driven by air from the air system, creating a vacuum of air containing carbon monoxide in the breech zone, with its subsequent removal from the breech and the fighting compartment through the casing and pipeline.

The method of removing powder gases from the breech of tank weapons is based on the fact that the air from the cylinders of the air system under pressure is used to rotate the impeller, which creates a vacuum of air saturated with powder gases in the breech zone, which is sucked into the casing and then through the impeller located in the casing and the non-return valve is removed through the pipeline from the fighting compartment, ensuring the removal of air containing carbon monoxide in the breech zone and an additional reduction in gas contamination oevogo department.

A method for removing powder gases from the breech of a tank weapon, including creating air back-up by a filter-ventilation unit and expelling air containing carbon monoxide from living compartments through leaks in the tank body, characterized in that when the armament is pressed, the signal is transmitted via electric wires to the time relay and to an actuating element (an electromagnet with a rod), open the first non-return valve, bleed air from the cylinder of the air system through the pipeline by which the porch is rotated A fabric that creates a rarefaction of air in the breech zone is forced to suck in air saturated with powder gases into the casing and through the impeller and a second check valve through a pipeline that are removed from the breech of the armament and reduce the level of gas contamination by the powder gases of the fighting compartment.

показано направление вращения крыльчатки.The invention is illustrated in figure 1, which shows a device that provides a method for removing powder gases from the breech of a tank weapon, where: 1 - fighting compartment; 2 - a casing; 3 - impeller; 4 - the first check valve; 5 - second check valve; 6 - pipeline release of powder gases; 7 - pipeline air supply from the cylinder; 8 - breech (gas source), 9 - small impeller with an axis, 10 - balloon of the air system; 11 - an actuating element (an electromagnet with a rod); 12 - electric wires; 13 - time relay; 14 - electric start. The dashed arrows (- →) show the movement of air saturated with powder gases, the straight arrows (→) show the movement of air from an air system cylinder. Arrow

the direction of rotation of the impeller is shown.

When you press the electric trigger of the main armament (gas source), the electric signal is transmitted via electric wires to the time relay, designed to transmit an electric signal from one element operating in one time mode to another element, changing the time mode of its operation. An electric signal is supplied from a time relay to an actuator (an electromagnet with a rod), which is designed to open the first non-return valve. The air under pressure in the cylinder of the air system flows through the air supply pipe from the cylinder, driving a small impeller with an axis. A small impeller with an axis is rigidly connected to the impeller, the rotation of which leads to the formation of rarefaction of air in the casing and the breech zone (gas source). Air saturated with powder gases is sucked into the casing and is removed through the impeller and a second non-return valve, which does not allow this air to pass in the opposite direction into the pipeline for the release of powder gases. There is a removal of powder gases from the breech zone of tank weapons and a decrease in the overall level of gas contamination in the fighting compartment.

An example of the method. During firing, when pressing the electric trigger 14, powder gases are emitted from the breech zone (gas source) 8. The electric signal is transmitted through electric wires 12 from the electric start 14 to the time relay 13, then to the actuator (electromagnet with a rod) 11, which opens the first check valve 4. Air from the cylinder of the air system 10 flows through the air supply pipe from the cylinder 7, causing small the impeller with an axis 9, which transmits torque to the impeller 3. The rotation of the impeller 3 forms a vacuum in the casing 2. The air near the breech (source) 8, saturated with powder gases, is sucked into the casing 2 and is removed through the impeller 3 and the second check valve 5 into the pipeline for the release of powder gases 6. There is a removal of powder gases from the breech zone (gas source) 8 and a decrease in the level of gas contamination in the fighting compartment 1.

The proposed method allows automatically, without the cost of electricity, to ensure the removal of air with powder gases from the breech zone of tank weapons, to reduce the level of maximum permissible concentration of powder gases in the fighting compartment and the probability of failure (death) of the crew.
