Method for removing explosive gas from inhabited compartments of military tracked vehicles

FIELD: weapons and ammunition.

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, in particular to methods of reducing pollution inhabited branches of the powder gases, a source of which is the armament of the tank.

A known method of removing gases from the inhabited branches of military tracked vehicles, when removal of the powder gases is carried out by the exhaust ventilation system with a fan inside the crew compartment (see Technical description of the amphibious combat vehicle (BMD-1) .-Military publishing house of the USSR, 1973, p.390, 392. Open edition).

In addition, the known method of removing gases from the inhabited sections for the T-72A, which consists in the fact that the filtering and ventilating unit provides a supply of purified air to the fighting compartment and the compartment of the machine and creates in them excessive pressure (boost pressure), and also provides ventilation of these branches, thereby reducing fumes when firing from a tank cannon and machine gun (see Technical description and operating instructions T-72A, the second book (part two.) Military publishing house of the USSR, 1989, pp.118. Open edition. The prototype).

A known method of removing gases from the inhabited branches of military tracked vehicles allows you to create backwater inhabited offices, and to reduce the overall level of gas ha powder is AMI. However, this method does not allow for full ventilation of habitable compartments, reduce the maximum allowable concentration of carbon monoxide to a safe value, isolating the source gases in the inhabited branches from the crew, the result of which can be the poisoning of the crew.

The present invention is to reduce the degree of pollution of the powder gases manned branches, reducing the maximum permissible concentrations of gases that appear when using weapons.

The technical result of the proposed invention is the provision of insulation of the source gases isolated volume from the crew in crew compartments, creating a negative pressure in the isolated volume and its subsequent removal by an electric motor with the propeller.

This method of removing gases from the inhabited branches of military tracked vehicles based on the fact that the source gases are placed in a stand-alone volume, in which clicking on a machine gun firing solenoid creates a negative air pressure through operation of the motor with the impeller, saturated gases air is removed from the isolated volume and manned branches in the pipeline.

Method of removing gases from the inhabited branches of the military huseni the different machines, including the creation of overpressure ventilation installation and ejection of air containing carbon monoxide, of the inhabited offices through leaks in the hull of the tank, characterized in that the pressing of electrically coaxial machine gun (source gases) signal is passed through the electrical wires through the time relay on the motor with the impeller, including in his work, during the rotation of the impeller motor creates a negative air pressure in the isolated volume, where the coaxial machine gun (a source gas), suck out the air, saturated with the powder gases, and under pressure to remove gases by pipeline from the isolated volume and inhabited branches.

The invention is illustrated by figure 1, which shows a device comprising a method of removing gases from the inhabited branches of military tracked vehicles, where 1 is the crew compartment; 2 - electrically; 3 - electric wiring; 4 - time relay; 5 - motor with impeller; 6 - a one-way valve; 7 - coaxial machine gun (a source gas); 8 - stand-alone volume; 9 - pipeline. In figure 1 the dashed line (- - -) shows the communication between the coaxial machine gun (a source gas) 7, electrically 2, time relay 4 and the motor 5.

Pressing the electrically coaxial machine gun (source gases) signal is transmitted via the electric wire on the relay time is, intended for transmission of an electrical signal from one element working in one-time mode to another element, changing the time mode for it. From time relay electric signal is supplied to the motor with the impeller. The motor is driven during rotation of the impeller creates a negative air pressure in the isolated volume. The air, saturated with the powder gases is removed from the isolated volume of the pipeline under pressure created by the impeller. To create a vacuum in a sealed and exclude the ingress of him gases in the crew compartment in the isolated volume is set one-way valve. Isolated volume where the source gases may be made of a material such as a polymer, rubberized fabric, metal, etc.

An example method to work. When you press the firing solenoid 2 coaxial machine gun (source gases) 7 the signal is passed through the electrical wires 3 time relay 4, include a motor with impeller 5, a one-way valve 6 opens and creates a negative air pressure in the isolated volume 8, which is coaxial machine gun (a source gas) 7. Pipeline 9 powder gases are removed from the isolated volume 8 and manned offices 1.

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