Description

The utility model relates to sights for weapons, in particular to sights for hand anti-tank grenade launchers.

There are a number of mechanical and optical sights for use in grenade launchers. Moreover, due to the ballistic characteristics of the ammunition, it is necessary to use an individual sight for each type of ammunition.

A device for the optical sight PGO-7V3 grenade launcher RPG-7V1 (RPG-7D2). This optical sight has a reticle with three scales for firing shots PG-7 V, PG-7 VM, PG-7 VS, PG-7 VL, PG-7 VR, TBG-7V. The additional use of the UP-7V sighting device allows you to aim with the OG-7V shot and increase the aiming range when using the TBG-7V shot. UP-7 V is a design that is installed between the standard optical sight of a grenade launcher and the universal mounting plate on weapons. Due to the movement of the moving parts of the device, it became possible to introduce increased aiming angles [1]. The disadvantages of this sighting system are:

the difficulty of aiming with different shots - the optical sight lens for each shot has its own aiming scale and the arrow must use different scales for different types of grenades;

the impossibility of using new types of shots using the available sight - a larger number of aiming scales at the same time to place on the lens is impractical;

limiting the aiming range for shots with a significant mass of the warhead - the sight field of view is 13 ° and does not allow to extend the vertical aiming scale.

However, in the construction of sights for other types of weapons, there are technical solutions to solve such problems [2, 3, 4, 5].

Close to the claimed technical solution is the PGO-7V optical sight to the RPG-7V grenade launcher system designed for use with the PG-7 V, PG-7 VM, GTG-7VS shots [1]. To ensure effective shooting using other types of shots with significantly changed ballistic characteristics, a change in the design of the sight is required.

The disadvantage of this design is the inability to ensure high-quality aiming by all types of existing shots (PG-7 V, PG-7 VM, PG-7 VS, PG-7 VL, PG-7 VR, TBG-7 V, OG-7V) due to significant differences in ballistic characteristics of shots:

- calibers of the head of grenades from 70 to 105 mm;

- the length of the shots from 716 to 1270 mm;

- the initial speed of grenades from 66 to 140 m / s,

- the maximum speed of grenades from 120 to 300 m / s [1, 6, 7, 8].

The technical result is aimed at the possibility of using a single reticle for ammunition with various ballistic characteristics, expanding the range of the range of aimed shooting.

The technical result is achieved by the fact that an optical sight is used, consisting of a housing, an arm, an optical system, a sight alignment mechanism, a grid lighting device when shooting at night and an eye cup, while a limb with several radially arranged installation scales is mounted on the axis between the housing and the arm firing range for ammunition with different ballistic characteristics, samples are made at the end of the limb corresponding to the initial position of the sight for firing each type of ammunition pass, in which the limb is fixed button installed in the bracket body, wherein there is a label on the housing of the sight, combine with the weakening of the eccentric

clamping with the necessary risk of the limb scale when setting the firing range for this type of ammunition.

Distinctive features of the prototype is that on the axis between the body and the arm there is a limb with several radially arranged scales for setting the firing range for ammunition with different ballistic characteristics, at the end of the limb there are samples corresponding to the initial position of the sight for firing each type of ammunition, on which the limb is fixed by a button installed in the body of the bracket, and on the sight housing there is a mark that is combined when loosening the eccentric clamp with the necessary Valium second limb of the scale when setting the firing range of this type of ammunition.

The figure shows an optical sight.

In the case 9 there is an optical system, the lens of which is protected by a cap 5, and the eyepiece - by an eye cup 10, a sight alignment mechanism 6, a grid lighting device when shooting at night 11. In the bracket 4, an axis 2, a spring-loaded button 3 are mounted. On an axis 2 between the case 9 and bracket 4 is set limb 1 with the applied scales for setting the firing range for various types of ammunition. Limb 1 at the end has samples 8, on which it is fixed from turning by button 3. On the body 9 there is a mark 14, combined with the risks of setting the required firing range 7 on the limb 1. The position of the body 9 is fixed relative to the limb 1 when the lever of the eccentric clamp 13 is turned, which through the washer 12 presses on the housing 9.

The optical sight works as follows:

A grenade is selected that will fire the next shot.

Clamp 13 loosens, button 3 is pressed.

By turning the dial 1, the adjustment sector for this type of ammunition is set and fixed by lowering the button 3.

The distance to the target is visually determined.

Arrow 14 on the housing 9 is combined with the risk of setting the required firing range 7 on the limb 1.

By turning the lever of the eccentric clamp 13, the position of the housing 9 is fixed.

Before firing, the grenade launcher is aimed at the target at the intersection of the upper horizontal and central vertical lines of the sight. If necessary, a lateral correction is set.

The utility model allows to simplify the aiming process, increase the aiming range and provide the ability to conduct aimed fire with all existing and promising shots.
