As the delivery vehicle, an unmanned aerial vehicle glider with an internal combustion engine or an electric engine and a parachute landing system is used, which ensures the movement of an air target, constructively and functionally creating a set of means for simulating the features of a highly maneuverable air target.

Description

The proposed useful model belongs to the field of military equipment, namely to simulators of aerial targets, and can be used in the development of technical means for teaching and training calculations of anti-aircraft systems (AC) for firing at highly maneuverable aerial targets, since the proposed simulator of highly maneuverable aerial targets allows to simulate a wide range characteristics of modern means of air attack: airplanes, cruise missiles, unmanned aerial vehicles, 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 highly maneuverable targets with their real characteristics, which makes it difficult to acquire the skills of shooting at aerial targets in the calculations of the trainees.

The closest analogue is an air target (2), the means of delivery of which used the rocket part 9M28 (9M22) of the 122-mm rocket projectile 9M28D (9M22U), accepted by the authors as a prototype. To increase the magnitude of the signal, the simulator of a high-speed air target contains a main part with a lens reflector placed in it and a heat emitter placed in a case with a radial window and located behind the lens reflector. The 9М28 (9М22) 122-mm rocket part of the 9мМ28Д (9М22U) rocket was used as a jet engine, which structurally and functionally creates a complex of means of simulating the characteristics of a high-speed air target.

The disadvantage of the analogue is that it can be used as an air target only for simulating targets, the main feature of which is high speed. However, the design of the air target simulator with the 9M28 (9M22) 122-mm rocket part of the 9M28D rocket as a jet engine has low maneuverability, which makes it impossible to simulate an air target that moves with significant changes in speed, course or altitude. It is also impossible to fly such an air target according to a previously created flight task.

Thus, the task of this close analogue was to provide an imitation of a fast-moving target with radar signatures.

The useful model is based on the task of creating a simulator of a highly maneuverable air target, which provides simulation of changes in the parameters of the target in terms of speed, course, height, radar features and is capable of flying according to a previously created flight task, which allows it to be used in training calculations of ZK with radar and thermal search, tracking and guidance systems.

The given technical task is solved in an air target simulator containing a radio-transparent fairing of the main part with a lens reflector and an infrared emitter unit located in it, which are integrated with the body of a motor delivery vehicle, according to a useful model, a glider of an unmanned aerial vehicle with a motor is used as a delivery vehicle internal combustion or an electric and parachute landing system, which ensures the movement of an air target, which constructively and functionally creates a complex of means of simulating the characteristics of a highly maneuverable air target.

The technical result that can be obtained when creating a useful model is the acquisition of the ability to simulate highly maneuverable air targets with variable parameters of speed, course, height, to fly according to a previously created flight task, to create additional features of the simulated target, namely infrared radiation and increase the effective surface dispersion with the simultaneous formation of a directional diagram of the predicted shape, and repeated use of the high-maneuverable air target simulator.

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

The proposed simulator of a highly maneuverable aerial target (Fig. 1) contains a radio-transparent fairing of the main part with an infrared emitter unit 1, an unmanned aerial vehicle glider with a control unit and a parachute landing system 2, and an engine 3.

The main part of the simulator of air targets (Fig. 2) has an infrared emitter housing 4, a lens reflector 5 with a metal coating 6, a fuselage of an unmanned aerial vehicle glider 7.

A new set of structural elements, as well as the presence of connections between simulator elements, allow, in particular, due to the use of: - a glider of an unmanned aerial vehicle with an engine as a means of movement with a control unit and a parachute landing system of a highly maneuverable aerial target:

- to provide simulation of changes in the parameters of the target in terms of speed, course, height and repeated use of the simulator due to the glider of an unmanned aerial vehicle with a control unit and a parachute landing system; - lens reflector in the form of a sphere made of radio-transparent material and metallization of not less than 90 95 of the rear surface: - to provide the necessary effective scattering surface; - an infrared emitter located behind the lens reflector: - to provide an imitation of the target's infrared radiation.

All of this together allows to simulate maneuvering and other characteristics of air targets, detection, tracking 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 - by an infrared signal from the simulator and the engine.

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

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

The launch and subsequent functioning of the simulator is carried out as follows: - before launch, the flight program is loaded into the flight control unit, the engine is turned on, the infrared emitter is turned on; - after starting the engine, the simulator leaves the launcher.

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 a radar on the opposite course, a radar pulse is sent to the lens reflector, which is reflected from the metallized surface in the opposite direction towards the locator. Based on the reflected radar pulses, guidance is carried out on the anti-missile simulator with the command control system. When the infrared emitter works, an imitation of a target is created that emits heat, which allows it to be detected and fired at with thermal missiles

With homing heads.

Thus, the use of a simulator of highly maneuverable air targets, which contains a radio-transparent fairing of the main part with a lens reflector placed in it, an infrared emitter, an unmanned aerial vehicle glider with a control unit and a parachute landing system, an engine, allows you to simulate air targets with variable parameters of speed, course, height , to fly according to a previously created flight task, to create an effective dispersion surface with the characteristics of an air target, and additional features, namely, the simulation of thermal radiation during the time of the high-maneuverability air target simulator in the air, as well as the repeated use of the high-maneuverability air target simulator.
