Description

The proposed useful model belongs to the field of military equipment, namely to air target simulators, and can be used in the development of technical means for teaching and training the calculations of anti-aircraft systems (ZK) for firing at high-speed air targets, since the proposed simulator of high-speed air targets allows simulating the main characteristics modern means of air attack: airplanes, cruise missiles, etc.

A well-known device for simulating air targets (1|) and testing ZK, which has a source of thermal radiation, a radio reflector surface, and a thruster with compressed air. This design provides guidance of anti-aircraft guided missiles (SMS) with various guidance systems based on radar and thermal characteristics of the target.

The disadvantage of the known device is the inability to simulate the flight characteristics of high-speed targets with their real speeds, which makes it difficult to acquire the skills of shooting at air targets in the calculations of ZK being trained.

The closest analogue is an air target (2), the means of delivery of which is an artillery projectile. To increase the signal value of the reflected radar signal, the target is equipped with a radar reflector. The reflector is attached to the bottom of the projectile and is mainly made of aluminum alloy. Moreover, the projectile is made with a caliber that exceeds the wavelength of the radar, the radar reflector is an additional part of the bottom, and its delivery to the observation site is carried out using a shot.

The disadvantage of the closest analogue is that the projectile can be used as an air target only for anti-missile defenses with radar means of search, tracking and guidance.

However, the radar reflector has a small effective scattering surface with an uneven pattern of direction, which can lead to the disruption of the tracking of the air target by the radar channel. It is also impossible to monitor the target by calculations of the ZK with optical and thermal channels of search, guidance and tracking of air targets, given the lack of a thermal feature in the target.

Thus, the task of the closest analogue was to provide an imitation of a target that moves quickly along a given trajectory and has radar features.

The essential compatible features of the closest analogue with the high-speed air target simulator proposed by the authors are the presence of a high-speed delivery vehicle

From an air target simulator and radar signal reflector.

The useful model is based on the task of creating a simulator of a high-speed air target, which provides simulation of the parameters of the target by speed, radar features and allows to simulate the thermal radiation of a real target, which allows it to be used in training calculations of ZK with radar and thermal search, tracking and guidance systems.

The task is solved due to the fact that in the closest analogue, where the means of delivery is an artillery projectile equipped with a radar reflector fixed on the bottom, and its delivery to the observation point is carried out using a shot, a 9M28 (9M22) 122-mm rocket part is additionally introduced rocket projectile 9M28D (9M22U) and the main part with a lens reflector placed in it, made in the form of a sphere with a diameter of at least 0.8 gauge from a radio-transparent material, while at least 9095 of the area of the rear surface of the lens reflector is metallized, in addition, the simulator is equipped with a heat emitter , placed in a case with a diameter of no more than 0.7 caliber with a radial window.

The technical result that can be obtained when creating a useful model consists in acquiring the ability to simulate high-speed air targets and creating additional features of the simulated target, namely thermal ones, and increasing the effective scattering surface with the simultaneous formation of a directional diagram of the predicted shape.

In fig. 1 shows the scheme of the proposed device.

The proposed simulator of a high-speed air target (Fig. 1) contains a radio-transparent fairing of the main part with a heat emitter housing 1, a missile part 9M28 (9M22) of a 122-mm rocket projectile 9M28D (9M22U) 2, a block of stabilizers 3.

The main part of the simulator of air targets (Fig. 2) has a heat emitter housing 4 with a heat emitter (tracer) placed in it 5, a lens reflector b with a metal coating 7. The main tube of the 9M28D (9M22U) missile part 8. Radial windows are made on the housing 9 , through which the combustion products of the heat emitter flow out.

A new set of structural elements, as well as the presence of connections between the elements of the simulator, allow, in particular, due to the implementation of: - the 9M28D (9M22U) missile part of the 122-mm rocket projectile 9M28D (9M22U) as a means of moving a high-speed air target:

to provide a high speed of movement of the air target simulator with the ability to change the distance and flight speed due to the additional use of a small and large brake ring from a set of 122-mm 9M28D (9M22U) rocket projectile; - a lens reflector in the form of a sphere with a diameter of at least 0.8 caliber made of radio-transparent material and metallization of at least 90 95 of the rear surface: to ensure the necessary effective scattering surface with a sphere diameter of at least 0.8 caliber, since with smaller sphere sizes there is a significant (up to 70 95) reduction of the effective scattering surface; - a heat emitter in a housing with a diameter of no more than 0.7 gauge with radial windows located behind the lens reflector: to provide simulation of thermal radiation of the target, the formation of a high-temperature zone around the heat emitter housing.

All of this together allows for the simulation of speed and other characteristics of air targets, the implementation of detection, escort and firing of the simulator with anti-aircraft systems with different guidance principles. The training of ZK calculations with radar means of targeting, detection and tracking of the target is carried out: - when firing in the opposite direction - according to the reflected signal from the lens reflector; - when firing in pursuit - based on the reflected signal from the aft part of the rocket engine.

When learning the calculations of the ZK equipped with optical and thermal guidance channels, detection and tracking of the simulator of a high-speed air target is done based on the target's thermal signature, which is provided by a thermal emitter.

The operation of the high-speed air target simulator device is as follows.

The launch and subsequent functioning of the simulator is carried out as follows: - before starting the rocket engine, the heat emitter is ignited; - after starting the rocket engine, the simulator descends from the launcher, at the same time, the blades of the stabilizing device C open and the simulator continues its flight with a burning heat emitter.

At a certain section of the trajectory, the simulator reaches the speed and flight height of the real target. When the simulator is irradiated by the radar on the oncoming courses, the lens reflector enters

Z is a radar pulse that is reflected from the metallized surface in the reverse direction towards the locator. Based on the reflected radar pulses, guidance is carried out on the ZKR simulator with the command control system. During the operation of the heat emitter, gaseous high-temperature products of combustion are released, which flow out through the windows on the body, which creates an imitation of a visible target that emits heat, which allows it to be detected and fired with missiles with thermal homing heads.

Thus, the use of the simulator of high-speed air targets, which contains the missile part of the 9M28 (9M22) 122-mm rocket projectile 9M28D (9M22U) and the main part with a lens reflector placed in it, a simulator of thermal radiation, allows to simulate high-speed air targets, an effective scattering surface with the characteristics , corresponding to the air target, and additional features, namely, simulation of thermal radiation during the time of the simulator of a high-speed air target in the air.
