Description

The proposal relates to the field of military equipment, in particular to devices for increasing the efficiency of monitoring the terrain, recognizing targets, determining the range to targets, targeting and adjusting machine-gun fire of a combat vehicle, as well as increasing the stealth of the sample on the battlefield.

A device is known that provides an increase in the efficiency of observation, for example, for a combat reconnaissance and patrol vehicle (Technical description and operating instructions for a combat reconnaissance patrol vehicle (BRDM-2). Book 1. Omsk, Publishing house of the RF Ministry of Defense GABTU, 2002, p. 86 , 89. Open edition), when an optical observation device TPKU-2B is used for observing the terrain, located in a rectangular cutout of a rotating flange, installed in a polustakan at the junction of the vertical front plate and the roof of the hull.

In addition, devices are known to increase the efficiency of observation for an infantry fighting vehicle (hereinafter - BMP-2) (Technical description and operating instructions for an infantry fighting vehicle (BMP-2). Part one. Publishing house of the RF Ministry of Defense 2001, pp. 10, 13 , 14, 154. Open edition.), In which the observation device TKN-3B and the illuminator OU-3GA2 are used to ensure observation of the terrain, search and detection of targets, determine the range to targets, as well as target designation and correction of fire in day and night conditions located in the tower - in the commander's hatch.

These devices allow you to monitor the terrain, provide search and detection of targets, adjust fire in day and night conditions.

However, these devices do not allow searching and detecting targets when monitoring the terrain in conditions of relatively high, dense vegetation (young forest, shrub), natural obstacles (hills, hillocks), that is, in conditions of limited visibility.

From the prior art, there is a known method for increasing the efficiency of observation from BMP-2 (Patent RU No. 2529117, IPC F41G 5/14, F41H 7/02, blasted 09/27/2014, Prototype.), Which is the closest in technical essence and achieved technical result to the claimed one, which includes a TKN-3B observation device and an OU-3GA2 illuminator, a telescopic rod with an optoelectronic observation device movably located on it, a pneumatic crane, an executive pneumatic cylinder, an air supply head connected by pipelines, an electromechanical stabilizer connected by an electric wire to a display and a control vertical guidance of the device.

The disadvantage of this method is that in the presented design it is not possible to quickly move the telescopic rod and lower the optoelectronic observation device to its original position. This leads to a decrease in the concealment of an object on the battlefield and, consequently, an increase in the likelihood of fire damage to the vehicle by the enemy.

The technical result of the claimed device is to increase the stealth of the vehicle on the battlefield.

The technical result is achieved by placing an ejector in the pneumatic line, the diffuser of which is connected to an electromagnetic valve by a pipeline.

The proposal is illustrated with pictures, where:

in fig. 1 shows the layout of the components of the claimed device;

in fig. 2 shows the operation of the ejector in the case of lifting the optoelectronic observation device;

in fig. 3 shows the operation of the ejector in the case of lowering the optoelectronic observation device to its original position.

The claimed device contains: 1 - machine tower; 2 - compressed air system; 3 - pipelines; 4 - pneumatic crane; 5 - executive pneumatic cylinder; 6 - ejector; 7 - electromagnetic valve; 8 - air supply head; 9 - device vertical guidance control; 10 - display; 11 - telescopic bar; 12 - electric wire; 13 - optoelectronic observation device; 14 - electromechanical stabilizer.

The claimed device for monitoring the terrain from the BMP-2 operates as follows. When observing from BMP-2 in conditions of limited visibility, when there is a need to raise the optoelectronic observation device to a certain height, the operator turns the pneumatic valve 4, and the air from the compressed air system 2 through pipelines 3, through the actuating pneumatic cylinder 5, enters the active flow nozzle ejector 6. In this case, the solenoid valve 7 is in the closed position, therefore, the air through the passive flow nozzle of the ejector 6 is supplied to the air supply head 8 and then enters the telescopic rod 11 mounted on the machine tower 1, opening it to the required height. Thus, the optoelectronic observation device 13 is lifted. The regulation in the vertical plane of the optoelectronic observation device 13 is carried out with the help of the electromechanical stabilizer 14 when it receives the signal from the vertical guidance control of the device 9 through the electric wires 12. 13 on the horizon occurs when the turret of the machine 1 is turned. Information from the optoelectronic observation device 13 is fed through the electric wires 12 to the display 10.

The operator can fold the telescopic rod 11 if it becomes necessary to lower the optoelectronic observation device 13 to its original position in two ways.

To use the first method, the operator stops the air supply through the valve 4, then opens the solenoid valve 7, which allows air to bleed from the internal cavities of the telescopic rod through the diffuser of the ejector 4 into the atmosphere (see Fig. 2). As a result, the telescopic arm folds smoothly under its own weight and the weight of the payload.

The second method can be used if it is necessary to quickly fold the telescopic rod 11, that is, to immediately lower the optoelectronic observation device 13 to its original position. To do this, the operator simultaneously turns the pneumatic valve 4 and opens the solenoid valve 7. In this case, air from the compressed air system 2 through pipelines 3, through the actuating pneumatic cylinder 5, enters under pressure through the active flow nozzle into the ejector 6, acquiring the required speed in it, creates a vacuum, thereby providing a more intensive bleeding of air from the internal cavities of the telescopic rod through the passive flow nozzle, and then through the ejector diffuser 6 and the solenoid valve 7 into the atmosphere (see Fig. 2). There is a rapid descent of the optoelectronic observation device 13.

In comparison with the prototype, the proposed device will provide an increase in vehicle stealth on the battlefield.
