RU2560229C1 - Method of removal of powder gases from tank armament gun - Google Patents

Abstract

FIELD: weapon and ammunition.

SUBSTANCE: method of removal of powder gases from the tank armament gun consists in that the breech-ring is placed in the isolated volume where after pressing the electric trigger the powder gases appear which are detected by the gas contamination level sensor which transmits a signal by electric cables through a timer to an executive element. The check valve installed in the pipeline connecting the air system with the isolated volume is effected, the pipeline is opened, air is bled from the air system into the isolated volume with the breech-ring, it is purged and gases are removed by the pipeline from the isolated volume and manned compartments.

EFFECT: possibility of isolation of the source of powder gases of a breech-ring using isolated volume from crew.

Description

The invention relates to the field of military equipment, in particular to methods for reducing the gas contamination of inhabited compartments by powder gases of objects of armored weapons, the source of which is weapons.

There is a method of removing powder gases from the guns of an object of armored weapons, when the removal of powder gases is carried out by an exhaust ventilation system with a fan inside the inhabited compartment (see Technical description, airborne 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 for removing powder gases from an armored weapon’s 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 SS SR, 1989, p. 118, open publication, Prototype).

The known method of removing powder gases from the guns of an object of armored weapons allows you to create a backwater in habitable compartments and partially reduce the overall level of gas contamination by powder gases. However, this method does not allow complete ventilation of the inhabited compartments to reduce the maximum permissible concentration of carbon monoxide to a safe value by isolating the gas source in the inhabited compartments from the crew, as a result of which poisoning (death) of the crew may occur.

The objective of the present invention is to remove powder gases from the breech of the main armament, reduce the level of gas contamination by the powder gases of the living compartments, and the maximum permissible concentration of powder gases that appear when using weapons.

The technical result of the proposed invention is the provision of isolation of the source of powder gases (breech) in an isolated volume from the crew located in the inhabited departments, and automatic purging of the isolated volume with air from the air system.

In this case, the method of removing powder gases from the guns of an object of armored weapons is based on the fact that the gas source (breech) is placed in an isolated volume, in which there is a gas level sensor that detects the level of powder gases in the air and when the air level reaches a certain level of powder gases the sensor transmits a signal to the actuator, which opens the check valve in the pipeline, to purge the insulated volume of air from the air system and remove air, containing powder gases from the living compartments through the pipeline.

A method for removing powder gases from an armored weapon’s weapon, namely, the breech is placed in an isolated volume, in which when the electric trigger is pressed, powder gases appear, detected by a gas level sensor that transmits a signal via electrical wires through a time relay to the actuator, a non-return valve located in the pipeline connecting the air system to the insulated volume, open the pipeline, bleed air from the air system to the insulated the first volume, where the breech, carried his purge gases and removed via line insulated from the scope and crew compartment.

The invention is illustrated in FIG. 1, which shows a device that ensures the operation of the method of removing powder gases from the guns of an object of armored weapons, where: 1 - actuator; 2 - electric wires; 3 - gas level sensor; 4 - pipeline; 5 - inhabited departments; 6 - air system; 7 - check valve; 8 - electric start; 9 - breech (gas source); 10 - isolated volume; 11 - time relay. In FIG. 1 dotted line (---) shows the telecommunication between the actuator 1, the timer 11, the gas level sensor 3, as well as the electric starter 8 and the breech (gas source) 9.

When you press the electric trigger of the gun, which includes the breech (gas source), the release of powder gases occurs. The breech is placed in an isolated volume in which a gas level sensor is located. When a certain level of gas content in an isolated volume is reached, the signal is automatically transmitted through electric wires from the gas level sensor, through a time relay, designed to change the time mode of operation (signal delay) to the actuator (electromagnet with rod), designed to convert the electric signal into translational motion rod, which acts on the check valve located in the pipeline. The non-return valve opens and air under pressure is vented from the air system (cylinder) into an insulated volume made of material, for example (polymer, rubberized fabric, metal, etc.), where the breech is located. The breech is purged in this volume, then the powder gases are removed through the pipeline from the isolated volume and inhabited compartments.

An example of the method. When you press the electric start 8, firing occurs with the formation of powder gases released from the breech 9. The gas level sensor 3 detects the presence of powder gases in the air of an isolated volume 10 and automatically transmits a signal via electrical wires 2 through a timer 11 to the actuator 1. The actuator 1 acts on a check valve 7 located in the pipe 4 connecting the air system 6 with an insulated volume 10. The pipe 4 is opened and the air from the air system 6 is bleed under pressure m in the isolation volume 10 where the breech block 9, carrying it and removing purge gas through line 4 from the isolated volume 10 and crew compartment 5.

The proposed method allows to reduce the level of maximum permissible concentration of powder gases in the inhabited compartments and to reduce the likelihood of poisoning (failure) of the crew.
