Description

The useful model belongs to the field of instrumentation, in particular to optical sighting, namely to devices for "cold" aiming of optical-electronic sights of combat vehicles, and can be used in the creation of control systems for combat vehicles equipped with television and thermal imaging sights.

Currently, "cold" sighting of optical-electronic sights of combat vehicles is carried out by two types of devices: devices that have muzzle nozzles, and devices with a "laser cartridge". Devices with muzzle nozzles, in turn, are divided into laser and optical.

A known "laser cartridge" containing a case in the form of a cartridge, which houses a laser that forms a beam collinear to the axis of the cylindrical surface of the cartridge (Fig. 11.

The disadvantages of the well-known "laser cartridge" include the fact that its use requires a target, which is not always acceptable in field conditions, during hostilities, and also requires the horizontality of the weapon barrel when aiming.

The disadvantage of the known device is that its use requires a screen, which is not always acceptable in field conditions during hostilities, and also requires the horizontality of the weapon barrel when aiming.

A well-known device for controlling the zero line of sighting of a combat vehicle of a reactive salvo fire system, which contains a muzzle nozzle with a "cold" aiming tube and a fiber-optic system for transmitting the image of the target on the aiming shield to the operator (41.

The disadvantage of the known device is that its use requires a shield, which is not always acceptable in field conditions during hostilities, and also requires the horizontality of the weapon barrel when aiming.

A known device for "cold" sighting of an optical-electronic sight, containing a collimator, the body of which is connected to a shank, intended: for mechanical contact with the barrel of a weapon in such a way that the optical axis of the collimator is collinear with the axis of the shank and is directed towards the optical-electronic sight (51.

The disadvantages of the known device include the following. First, with a large base between the barrel of the weapon and the sight, which is inherent in combat vehicles in contrast to small arms, the connecting element that fastens the body of the collimator to the shank must be rigid to maintain the collinearity of the axes of the collimator and the shank. This leads to a large mass of the device and to the inconvenience of its use. Secondly, the device is not universal: it does not provide aiming at a different base of the weapon barrel and sight, for different types of optical-electronic sights that work in different spectral ranges - visible and far infrared.

The closest, technical solution, both in essence and the problem to be solved, which was chosen as the closest analog (prototype), is a device for "cold" sighting of an optical-electronic sight, containing a collimator, the body of which is connected to the shank, intended for mechanical contact with the bore of the weapon, so that the optical axis of the collimator is collinear with the axis of the shank and is directed towards the optical-electronic sight (51.

The disadvantages of the known device, which is chosen as the closest analog (prototype), include the following. First, with a large base between the barrel of the weapon and the sight, which is inherent in combat vehicles in contrast to small arms, the connecting element that fastens the body of the collimator to the shank must be rigid to maintain collinearity of the axes. This leads to a large weight of the device and to the inconvenience of its use. Secondly, the device is not universal: it does not provide aiming at a different base of the weapon barrel and sight, for different types of optical-electronic sights that work in different spectral ranges - visible and infrared.

The useful model is based on the task of introducing a mirror assembly at the output of the collimator for the optical coupling of the collimator with the sight: to ensure in the complex "cold" aiming of various types of sights placed at different distances from the barrel of the weapon, as well as to reduce the weight of the device.

The task is solved by the fact that in a device for "cold" aiming, which contains a collimator, the body of which is connected to a shank designed for mechanical contact with the bore of the weapon, in such a way that the optical axis of the collimator is collinear with the axis of the shank, it is that the device additionally includes a mirror unit containing two pentamirrors, the first of which is installed on the optical axis of the collimator, and the second is installed on the optical axis of the collimator reflected by the first pentamirror, with the possibility of changing the distance to it for optical coupling with the optical-electronic sight , which is being shot.

A comparative analysis of the technical solution with the prototype allows us to conclude that the claimed device differs in that. that it includes a mirror unit containing two pentamirrors, the first of which is installed on the optical axis of the collimator, and the second is installed on the optical axis of the collimator reflected by the first pentamirror, with the possibility of changing the distance to it for optical coupling with an optical-electronic sight, which shoot at

The drawing explains the essence of a useful model. Fig. 1-Fig. 5.

In fig. 1 presents the construction principle of the claimed device.

In fig. 2 shows a section of the second pentamirror along the B-B line.

In fig. Here are the pictures that the operator observes on the sight display during "cold" aiming.

The claimed device for "cold" aiming contains a collimator 1, the body 2 of which is connected to a shank 3, designed for mechanical contact with the bore 4 of a weapon of a combat vehicle, on which the sight 5 is installed, and a mirror unit b, intended for optical conjugation of the collimator with the optical-electronic sight 5, which is aimed at.

The collimator 1 contains a body 2, a mirror lens 7, and an aiming grid 8, which is illuminated by a global energy source 9. The optical axis 10 of the collimator is collinear to the geometric axis 11 of the shank 3. The aiming grid 8 is made in the form of a hole in an opaque part.

The mirror unit 6 contains a body 12 with base planes Bi B: and two pentamirrors 13 and 14. The peculiarity of the pentamirror-an analogue of a pentaprism is that it maintains the constancy of the angle of 90" between the input and output rays regardless of the orientation of the pentamirror relative to the optical system that forms The pentamirror C is installed stationary in the housing 12 at the output of the collimator 1 and reflects its optical axis 10 at an angle of 902 to the pentamirror 14. The pentamirror 14 is installed on the reflected optical axis and, in turn, reflects it at an angle of 907 in the direction of the sight 5, which is aimed at Thus, the optical axis 10 at the output of the pentamirror 14 is collinear with the optical axis 10 at the output of the collimator 1. In addition, the pentamirror 14 is installed in the housing 12 with the possibility of changing the distance to the pentamirror 13, thereby changing the base A between the barrel 4 of the weapon and the sight 5. in the process of changing the base A, the pentamirror moves along the base plane B in the housing 12 along the base plane B." Housing 12 is equipped with a imeter scale 15 to simplify the preliminary exhibition of base A.

The device for "cold" shooting, which is claimed, is used (applied) as follows (Fig. 1).

In the process of aiming the sight of a specific combat vehicle, parameter A is known in advance.

The operator, who conducts the shooting, sets the pentamirror 14 in the position that corresponds to parameter A, using the scale 15, and fixes it in this position.

Next, the operator installs the shank 3 in the channel 4 of the weapon barrel and turns on the source 9. Beams from the hole in the grid 8 fill the aperture of the mirror lens 7, are collimated, pass through the pentamirror 13 and exit the pentamirror 14 collinear with the axis of the barrel channel 4 of the weapon. The operator rotates the device around the axis of the shank Z so that the pentamirror 14 is opposite the sight 5, and turns on the sight 5 in the "calibration" mode. In this mode, the sight display screen 5 displays the calibration grid 16 (Fig. 3), which is graduated in angular minutes. At the same time, point 17 is displayed on the sight display 5, which shows the axis of the gun barrel 4. If the point 17 and the intersection of the calibration grid 16 do not match, the operator combines them by moving the calibration grid 16 in the sight 5, turns off the source 9, removes the device from the barrel and switches the sight to the "shooting" mode. In this mode, the image of the calibration reticle 16 remains on the display screen and the image of the main reticle 18 of sight 5 appears, which must be aimed (Fig. 3). In the event of a mismatch, the crosshairs 16 and 18 are aligned by the operator by moving the sighting reticle 18. As a result of these operations, the crosshairs of the sighting reticle 18 are aligned with the geometric axis of the bore of the weapon 4, i.e. "cold" sighting (calibration of the sighting line) is completed.

If the geometric axis of the barrel channel 4 of the weapon does not coincide with the actual direction of departure of the ammunition, which depends on the manufacturing technology of the barrel 4, then the vertical av and horizontal ag components of the divergence angle are known a priori (Fig. 4). These components are indicated in the method of "cold" target shooting for each weapon. In this case, the operator, using the scale of the calibration grid

16, moves the sighting grid 18 to a position that ensures the divergence of the intersections of the grids 16 and 18 at the angles of the vertical and horizontal angles (Fig. 4).

As a result of this operation, the intersection of the aiming grid 18 is combined with the actual direction of departure of the ammunition, i.e. "cold" aiming is completed.

Since the device uses mirror optics, it is suitable for "cold" sighting of sights that work in the visible and infrared spectrum (television and thermal imaging). When performing "cold" aiming of thermal imaging sights, a mylar screen with a hole corresponding to the diameter of the beam beams at the output of the device is installed at the exit of the pentamirror 14 (the screen is not shown in Fig. 1). The peculiarity of the mylar film is that it is opaque to infrared rays, and the screen excludes heat rays from the housing 12 of the mirror unit b, which has an ambient temperature, from entering the field of view of the thermal imaging sight.

Thus, the device for "cold" aiming, which is claimed. provides, in comparison with the prototype, universality of use: it carries out "cold" sighting of sights that work in a wide spectral range, with different bases of weapons and sights, and at the same time has less weight than the prototype.
