Description

The proposed utility model relates to night vision sights and is designed to detect air targets in night conditions, provide the possibility of firing at them with portable anti-aircraft missile systems, and can also be used as part of reference launchers.

Known optical sight I, which can be used as a universal sight for day and night aiming shooting. The device I contains optics for daytime observation, a node for forming an aiming grid and a night vision device. Optics for daytime observation is made in the form of a lens, an image wrapping system, plane-parallel w plates with a reticle on it, illuminated by HCTO4HnKONi light, and an eyepiece. The same reticle was introduced into the night-vision device through the optics of daytime observation by optically combining parts of the field of view of the daytime observation lens and the lens of the night vision device. This is accomplished by introducing a truncated triangular prism.

The closest in their technical essence to the claimed utility model is a night vision sight 2, containing a lens, an electronic; optical converter, an aim reticle with

stamp and eyepiece. The advantage of night vision sight 2 is that the internal component of the lens is equipped with a movement mechanism in a plane perpendicular to the optical axis of the sight, and the aiming mark is fixed. The mechanisms of movement of the lens component are equipped with reading drums, which makes it possible to make corrections to the aiming mark when shooting (adjustments for wind and bullet trajectory).

Common disadvantages of the analogue and the prototype is the lack of indication of target capture, which makes it difficult to use them on anti-aircraft missile systems.

The objective of the proposed utility model is to expand the functionality of the sight, namely, providing indications of target acquisition and indicating the ground radar interrogator of someone else's.

To solve this problem, a night vision sight is proposed, which, like the one closest to it, selected as a prototype, consists of a series-mounted lens, an electron-optical converter (EOC) mounted in the frame of the reticle with a mark and an eyepiece. A feature of the proposed night vision sight that distinguishes it from the known device 2 is that LEDs are additionally introduced into the frame of the reticle in a plane perpendicular to the optical axis of the sight. A pair of LEDs are mounted against each other and are electrically connected to the target capture indicator. One LED is connected to the target capture indicator and to

your radar interrogator is your own - a stranger.

The fulfillment of the task posed when creating the proposed utility model was made possible thanks to the following.

Three LEDs are additionally introduced into the frame of the reticle, two of which serve as an indication of target capture in the case of using a night vision sight as part of a launcher (OPU). When the desired object falls into the central zone of the grid, the LED (green) lights up, indicating the capture of the target of one of the homing optical guided missiles. The third LED (red), when an object enters the central zone of the grid, gives out a signal identified by a ground-based radar interrogator - its own - alien. In the case of using night vision sight in a man-portable air defense system (MANPADS), the third LED (red) serves as an indication of target acquisition.

Thus, the combination of the above features allows us to solve the problem.

The proposed night vision scope is illustrated by the drawings shown in FIG. 1 and FIG. 2.

In FIG. 1 presents a General view of one of the specific examples of the implementation of the proposed utility model;

-1 Night vision scope (Fig. 1) consists of a lens 1

fixed on the housing 2 sights. Inside the housing 2 is an electron-optical converter (EOP) 3 and an electronic unit 4 (Fig. 2), which performs the functions of a switching unit. A grid 6 with a mark and newly introduced elements, namely, LEDs 7, 8 and LED 9, offset by 90 ° relative to the axis of the LEDs 7, 8, is mounted on the outer surface of the housing 2, is mounted on the outer surface of the housing 2 ( Fig. 1), designed to connect the cable (not shown in Fig.), connecting the sight with MANPADS and OPU. On the opposite side of the lens 1 to the housing 2 is attached to the eyepiece 11.

The sight works as follows. The image of the object is transmitted by the lens 1 to the intermediate plane aligned with the plane of the image intensifier cathode 3. The image that appears on the image intensifier screen is viewed by the eyepiece 11. The sight is directly on the launcher (not shown in Fig.) And the electric cable is connected to the homing head. In the case of using the sight as part of the MANPADS, an electric signal is supplied and the red LED 9 lights up in the observer’s field of view. In the case of using the sight as part of the control device, the red LED 9 is an indicator of the signal from the ground radar interrogator. When indicating your object, the red LED 9 lights up. Each of the green LEDs 7, 8

(

4 acts as a target capture indicator of the corresponding optical

homing head (OGS) anti-aircraft guided missile.

Thus, the introduction of LEDs designed to indicate the signal of target acquisition and the interrogator signal of someone else’s allowed to expand the functionality of the sight, ensuring its use in MANPADS and on the control system.
