Description

The invention relates to the field of military equipment, in particular to methods of preserving the buoyancy margin of a military tracked vehicle in the event of flooding of inhabited compartments while overcoming a water barrier.

Known methods for maintaining the buoyancy reserve of military tracked vehicles during flooding of habitable compartments are as follows: to provide the necessary margin of buoyancy of the vehicle during flooding of inhabited compartments, the following are used: machine body, box-type wings made of aluminum alloy sheets, and floats made of steel sheets filled with water-absorbing material, as well as bilge pumps (see. Technical description and instruction manual for an infantry fighting vehicle (BMP-2). Military publisher in the Russian Ministry of Defense, 2001 (the first, second), second edition, pp. 43, 53, 116, 117, 118. Open Edition).

In addition, a well-known system of balanced distribution of buoyancy is known, in which, when water flooded the inhabited compartments of a vehicle, the signal is transmitted via electric wires from the remote control to start the system to the squibs of cylinders with a gas mixture, cylinder shut-off devices are opened, through the gas distribution system (pipelines) through check valves, gas with a mixture under pressure fill inflatable buoyancy chambers, increase the volumetric displacement of the vehicle, create favorable conditions for its further eva This ensures a buoyancy margin of the vehicle and creates more favorable conditions for its further evacuation from the water by other means, in case of flooding of the inhabited compartments. (WO 9515279 A1, B63B 43/14, 08/06/1995 (COOK JULIAN EDVIN), description, p. 11, lines 10-24, fig. 1, 1a, 2a, 2b, total 36 pp. Patent. Open Publication . Prototype).

The well-known system of balanced distribution of buoyancy allows you to quickly create the necessary buoyancy margin for the machine and ensure its further evacuation by water, in case of flooding of the inhabited compartments. However, this system has several disadvantages:

- with the use of this system, a machine can overcome only one water barrier, since cylinders with a gas mixture require recharging when they are used once;

- inflatable buoyancy chambers can be compressed under the influence of water pressure, thereby reducing the volumetric displacement and the likelihood of flooding of the machine increases;

- the volume of the buoyancy chambers filled with the gas mixture can vary significantly depending on the ambient temperature, which can lead to the rupture of the buoyancy chamber or its insufficient opening when filling the mixture at low temperatures, which, in turn, will not provide the necessary margin buoyancy of the car.

The objective of the present invention is to provide the necessary stock of buoyancy of a combat vehicle, in the event of flooding of the inhabited squads while overcoming more than one water barrier, creating more favorable conditions for its further evacuation to the shore (shallow water).

The technical result of the proposed invention is to ensure a buoyancy reserve for a military tracked vehicle when it is damaged in combat - breaking through armor, when overcoming several water obstacles, and also creating more favorable conditions for its further evacuation from water by other means in case of flooding of inhabited compartments.

The technical solution of the proposed invention is the use of additionally installed inflatable buoyancy chambers with a frame metal base, filled with air from a high-performance compressor driven by a regular internal combustion engine (hereinafter - ICE) of the machine through the controls, an electromagnet with a rod and a coupling that increase the volumetric displacement combat vehicle, in the event of a leak and flooding of habitable compartments.

In this case, the method of preserving the buoyancy reserve of a military tracked vehicle during flooding of inhabited compartments is based on the fact that in the case of water entering the inhabited compartments of a vehicle afloat and the inability of regular water pumps to pump out incoming water, a signal from a water presence sensor installed in inhabited compartments, transmitted by electrical wires to the remote control of the driver in the form of sound and light alarms. The driver through the control (toggle switch) and the electromagnet with the rod includes a clutch, and the torque from the ICE shaft is transmitted through the shaft and clutch to a high-performance compressor. Air from the compressor through the valve enters through the gas distribution system (pipelines) to the inflatable buoyancy chambers inside, in a rigid coupling with folding metal frames mounted symmetrically, along the sides of the combat vehicle in the folded position. When filling inflatable buoyancy chambers with air, folding metal frames open, automatically locking in the unfolded position, thereby increasing the volumetric displacement and eliminating the compression of the buoyancy chambers created by the water pressure, and keeping the machine afloat.

A method of preserving the buoyancy margin of a military tracked vehicle during flooding of inhabited compartments, including transmitting a signal through electrical wires from the remote control to start the system on the squibs of cylinders with a gas mixture, opening shut-off devices for cylinders, through a gas distribution system (pipelines) through check valves, filling an inflatable gas mixture under pressure buoyancy chambers that increase the volumetric displacement of the vehicle, characterized in that when flooding the habitable compartments, the signal is transmitted by electric wire I will give the clutch from the water availability sensor located in the living compartments to the driver’s control panel, control (toggle switch) and an electromagnet with a rod, transmit torque from the engine through the shaft through the clutch to a high-performance compressor, fill it with air through the gas distribution system under pressure (pipelines) through the valves, inflatable buoyancy chambers open folding metal frames, automatically locking, increase the volumetric displacement of the combat vehicle, keep the car afloat, not allowing its flooding with repeated overcoming of the water barrier.

The invention is illustrated in figure 1, which shows a device that ensures the operation of the method of preserving the buoyancy margin of a military tracked vehicle during flooding of habitable compartments, where: 1 - inhabited compartments; 2 - high performance compressor; 3 - electric wires; 4 - water availability sensor; 5 - governing body (toggle switch); 6 - frames with mounts; 7 - gas distribution system (pipelines); 8 - valves; 9 - inflatable buoyancy chambers; 10 - folding metal frames; 11 - remote control mechanics - driver; 12 - shaft; 13 - an electromagnet with a rod; 14 - coupling; 15 - ICE. In figure 1, a dotted line (..........) shows the position of the inflatable buoyancy chamber filled with the gas mixture, a dotted line (---) shows the open position of the folding metal frame.

In case of flooding of the inhabited compartments with water, the signal from the water availability sensor is transmitted via electric wires to the driver’s console, informing it with sound and light alarms about the presence of water in them.

The driver through the control (toggle switch) transmits a signal via electrical wires to an electromagnet with a rod, which is designed to turn on the clutch. When the clutch is turned on, the torque from the ICE shaft is transmitted through the clutch to a high-performance compressor. Air from a high-performance compressor through the valves enters the gas distribution system (pipelines) to inflatable buoyancy chambers located in folding metal frames mounted symmetrically, on the sides of the combat vehicle in the folded position, mounted on frames with mounts. Frames with fasteners are necessary for rigid coupling with the machine of folding metal frames and inflatable buoyancy chambers inside them. The valves are designed to control the pressure in the buoyancy chambers with folding metal frames and to prevent their rupture when the pressure reaches above normal. Therefore, when a certain pressure is reached, air is vented through the openings in the valves into the atmosphere, bypassing the chambers. When inflatable chambers with folding metal frames are filled with air, the chambers of the chambers open and fix, preventing the chambers from being compressed by the pressure of the water. Folding metal frames can be made in the form of parallelepipeds (for example, from aluminum tubes). Thus, the volumetric displacement of the chambers increases during forced injection of air into them and excluding their compression caused by water pressure, as well as their rupture during pumping, which is provided by valves.

An example of the method. When the inhabited compartments 1 are flooded with water, the signal from the water presence sensor 4 is transmitted via electrical wires 3 to the remote control of the driver 11. The driver through the control (toggle switch) 5 transmits a signal via electrical wires 3 to an electromagnet with a rod 13, which includes a clutch 14. The torque from the ICE shaft 15 is transmitted through the shaft 12 and the clutch 14 to the high-performance compressor 2. Air from the high-performance compressor 2 through the valves 8 enters through the gas distribution system (pipelines) 7 to the inflatable buoyancy chambers 9, firmly bonded with folding metal frames 10, mounted on frames with mounts 6. When inflatable buoyancy chambers 9 are filled with air, the folding metal frames 10 open and automatically lock, preventing the chambers from being compressed by the pressure of the water. Thus, the volumetric displacement of the buoyancy chambers 9 is increased, the lifting force is increased, and the machine is kept afloat.

The proposed method allows to increase the volumetric displacement of a military tracked vehicle, to provide the necessary buoyancy margin when flooding the inhabited compartments, while overcoming several water barriers, to prevent flooding of the vehicle in these conditions, as well as the death of the crew.
