Abstract

FIELD: military.

SUBSTANCE: invention relates to the preparation of artillery weapons for combat use. The claimed method of reconciliation includes fixing the cross hairs at the marks on the muzzle brake of the gun, levelling the gun barrel, installing aiming devices in regular places, installing a periscope artillery aiming circle (PAB-2A) in front of the gun at any distance convenient for work, levelling the PAB-2A along the ball levelling and aiming it at the crosshairs on the cut of the muzzle brake of the gun, setting 30-00 on the goniometric ring and goniometer drum, checking the zero settings of the sight. In this case, the crosshairs on the cut of the muzzle brake of the gun are directed to the middle of the ball heel of the periscope artillery aiming circle, then the periscope artillery aiming circle is pointed at the head of the panorama of the sight and the resulting goniometer value is read, the gun is marked in relation to the periscope artillery aiming circle and the goniometer reading is read from the view finder. In case of inequality of angles, the goniometer reading of the panorama obtained from the periscope artillery aiming circle is set according to the scales of the goniometer mechanisms: 4 screws on the locking bar are unscrewed by 1-2 turns and the index is combined with the number of the goniometer of the periscope artillery aiming circle by rotating the cam.

EFFECT: ensuring the alignment of the zero line of aiming the optical sight of an artillery gun in any conditions of a combat situation, under any weather conditions, at any time of the year and day.

Description

The claimed invention relates to the preparation of artillery weapons for combat use and concerns a method for aligning the parallelism of the optical axes of pickup devices, the axis of the bore of an artillery gun.

One of the main measures for preparing an artillery gun for firing is the alignment of the zero line of sight of an optical sight.

Artillery guns are known from the prior art, on which the alignment of the zero aiming line is carried out after checking the zero settings of the sights. Where the zero line of sight is checked by a remote point on the ground (no closer than 1000 m) or by the corresponding crosshairs on the alignment board. To this end, it is necessary to pull the threads along the risks applied on the muzzle of the barrel, remove the bolt wedge and the percussion mechanism. Further, sighting through the hole for the exit of the firing pin and the center of the cross hairs on the muzzle, aim the gun barrel at the aiming point. Then, by rotating the handwheels of the goniometer and the panorama reflector, or align the top of the central square with the point at which the crosshairs are pointed at the muzzle of the gun barrel (2A18M. Technical description and operating instructions. M .: Voenizdat, 1981, p. 80.) At the same time, devices have the following disadvantages: limited sighting capabilities at a remote point at a distance of 1000 m, low accuracy and the additional presence of a calculation number.

Alignment of the zero line of aiming of the optical sight of an artillery gun is carried out in accordance with the requirements of the technical description and operating instructions for each gun.

Alignment of the zero aiming line is carried out according to a remote aiming point located at a distance of at least 1000 m or according to the corresponding crosshairs of the alignment shield, set at a distance of 50-100 m. [1-7]

The disadvantage of this method is that the choice of a remote point is influenced by weather conditions, time of year and day, and for alignment with the alignment board, it must be made in accordance with the requirements [1-7], fixed on the ground, vertically installed using a sheer level , which in conditions of rocky soil and sub-zero temperatures is a serious problem. This method is taken as a prototype.

Close to the claimed invention "Universal device for aligning sights on artillery systems" (utility model patent No. 189 508 dated 2019.05.24). The disadvantage of this utility model is that in order to align the zero line of sight, it is necessary to manufacture additional devices. This, in turn, entails the expenditure of additional material resources, time and space for transportation.

Invention No. 2 695 141 “METHOD FOR AUTOMATIC RECONCILIATION OF ZERO AIMING LINES OF OPTO-ELECTRONIC AIMING CHANNELS OF ARMORED ARMOR SIGHTS” of 2018.10.22. The use of the invention requires additional devices, and is more suitable for field research, and not for combat work.

The above problems are solved by the claimed invention.

The essence of the claimed invention is illustrated by the drawing (see figure 1) and consists in reconciling the zero line of sight of the optical sight of an artillery gun in any combat situation, under any weather conditions, at any time of the year and day using a standard device of all artillery units - compass PAB -2A.

Figure 1 shows a diagram of the use of the theorem of parallelism of straight lines at the intersection of their secant and equality of cross lying angles, when aligning the zero line of aiming of an optical sight using a standard device of all artillery units of the PAB-2A compass,

Where:

1- compass PAB-2A, set at any distance from the gun;

2 - line of the gun barrel;

3 - optical sight.

To carry out the invention, it is necessary:

1. Level the implement in the longitudinal and transverse directions. Install optical aiming devices in regular places.

2. Install PAB-2 in front of the gun at any distance convenient for work.

3. Horizontate PAB-2 on a ball level and aim the compass at the crosshairs of the threads on the gun barrel. In this position, install a 30-00 goniometer on the goniometer ring and drum.

4. The commander of the gun with the gunner, sighting through the barrel of the gun and a crosshair of threads on the barrel, point the line of the barrel into the middle of the ball heel of the compass.

5. Upon completion of these measures, the senior officer of the battery (SOB) or the commander of the firing platoon (KOV) gives the command to the gun commander: "MAKE MARK ON THE COMPASSOL", and he directs the compass to the panorama head of the sight and reads the received goniometer, for example 29-85.

6. The gunner is marked by the compass and reads the protractor from the sight, for example 29-85. Reports it to SOB (KOV).

7. If the angles are equal, then the line of the trunk and the panorama are parallel!

Reconciliation completed.

If the angles are not equal:

1. SOB commands the goniometer obtained on the compass, for example 29-85, to correct the goniometer.

2. The gunner sets the reading of the goniometer panorama 29-85 according to the scales of the goniometer mechanisms, for which:

- unscrew 4 screws on the locking plate by 1-2 turns and combine the index with the number "29-85" by turning the cam.

check the countdown of the panorama reflector 0-00, if the countdown does not match, it is necessary to unscrew the screw fixing the scale in the handwheel UP-DOWN by 1-2 turns and set the zero countdown against the risk, unscrew 3 screws by 1-2 turns and align the index with the cam zero dash.

3. Upon completion of these activities, the reconciliation is completed.

This method allows you to align the zero line of sight using PAB-2 or any other angle measuring device on any terrain, without having a remote point and alignment shield. Here it is also possible to align several guns from one PAB-2 location at once, which significantly reduces the time for alignment.

The technical result obtained by the claimed invention consists in reconciling the zero line of sight of the optical sight of an artillery gun using the PAB-2A compass in any conditions of a combat situation, under any weather conditions, at any time of the year and day, reducing the time for reconciliation to 40%.
