Abstract

FIELD: weapons and ammunition.

SUBSTANCE: method of reduction of gas content of powder gases of crew compartment of the fighting vehicles is that when pressing the electric trigger of the main armament the signal is transmitted by electrical conductors through the time switch to the electric motor with the impeller and it is actuated. In rotation of the impeller of the electric motor the rarefaction of air is created, which is saturated with powder gases, it is sucked into the catalytic neutraliser-filter, the air is purified and removed in the crew compartments.

EFFECT: reduction of gas content of crew compartments from powder and exhaust gases.

Description

The invention relates to the field of military equipment, in particular, to methods for reducing the level of gas contamination of inhabited compartments by powder gases, the source of which is the main armament of military vehicles.

There is a method of reducing the level of gas contamination by gunpowder gases of inhabited compartments of combat vehicles 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 for reducing the gas contamination level of the occupied compartments for the facility 219Р, 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 ventilates these compartments thereby reducing gas contamination when firing from a tank gun and machine gun (see Technical Description and Operation Instructions for Object 219P, second book. Moscow. Military publishing house USSR Ministry of Defense 1986, p.575. Open edition. Prototype).

The known method of reducing the level of gas contamination by powder gases of the inhabited compartments allows to create a backwater in the inhabited compartments and partially reduce the overall level of gas contamination by the powder gases. However, this method does not allow the necessary ventilation of the inhabited compartments, to reduce the maximum permissible concentration of carbon monoxide to a safe value when firing with high intensity, especially in the area of combat placement, since some of the undeleted gases remain in the shot pallets of shells, as a result of which poisoning (strangulation) of the crew.

The objective of the present invention is to reduce the degree of gas contamination by powder gases in inaccessible places in inhabited compartments, to reduce the level of maximum permissible concentration of powder gases that appear during intensive use of the main armament, as well as gas contamination by exhaust gases, due to their penetration from the engine-transmission compartment.

The technical solution of the proposed invention is the setting of a gas analyzer, an electric motor with an impeller and a catalytic converter-filter, which automatically extract and purify air containing powder gases.

The technical result of the proposed invention is the provision of filtration of air space containing powder gases in inaccessible places, a general reduction in the gas contamination of the living compartments from both powder and exhaust gases.

In this case, the method of reducing the level of gas contamination by the powder gases of the inhabited compartments of combat vehicles is based on the fact that in places of the greatest accumulation of powder gases an electric motor is installed with an impeller and a catalytic converter-filter. When you press the electric trigger of the main gun, the signal is transmitted to the time relay and the electric motor with the impeller, bringing it to work. The rotation of the impeller of the electric motor creates a vacuum. Air saturated with powder gases passes through the catalytic converter-filter, it is cleaned and the overall gas contamination in the inhabited compartments decreases.

A way to reduce the level of gas contamination by the gunpowder gases of the inhabited compartments of military vehicles, which consists in the fact that when the main weapon is pressed, the signal is transmitted via electric wires through a time relay to the electric motor with an impeller, they are turned on, and when the electric impeller rotates, they create a vacuum of air saturated with powder gases, they suck it into the catalytic converter-filter, purify the air and remove it to the inhabited compartments.

Figure 1 is dotted (

) shows air saturated with powder gases, a straight line (

) - purified air.

When you press the electric trigger of the main armament (gas source), the signal is transmitted via an electric wire to a time relay, designed to transmit an electric signal from one element operating in one time mode to another element, changing its time mode of operation. An electric signal is supplied from a time relay to an electric motor with an impeller. The electric motor is put into operation and when the impeller rotates, it creates a vacuum. Further, the air saturated with powder gases passes through the pipe into the catalytic converter-filter, where it is cleaned. Further, the purified air passes through the pipe into the inhabited compartments.

An example of the method. When you press the electric trigger 3 of the main armament 2, the signal is transmitted via electric wires 4 to the time relay 5, the electric motor with the impeller 6 is turned on, the powder gases are sucked into the catalytic converter-filter 8 through the pipe 7, they are cleaned and removed to the inhabited compartments 1.

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