Description

The proposed utility model relates to training equipment for training calculations of anti-aircraft systems.

Known simulator of air targets related to the simulation of moving targets. The essence of the invention lies in the fact that the simulator is equipped with a head and tail parts made in the form of replaceable modules, which are designed to create a radar and / or infrared image of the target (RF patent No. 2193747, claimed. 02.20.2002, publ. 27.11.2002, bull. No. 33.)

A well-known universal simulator of air targets (see, for example, RF patent No. 2147722, application. June 15, 1998, publ. 04/20/2000, bull. No. 11), which imitates real targets in speed, trajectory, effective scattering surface and thermal radiation. The specified simulator of air targets contains a rocket engine and a head part with a lens and corner reflectors placed therein. The lens reflector is made in the form of a sphere, and the corner reflectors are in the form of cross-shaped elements with transverse diaphragms located at a step 4-6 of the wavelength of the irradiating locator and have an electrically conductive coating.

Known aerial target, equipped with a solid fuel charge and a parachute system, located in the housing, RF patent No. 2187064, decl. 03/14/2000, publ. 08/10/2002.

Common disadvantages of well-known simulators of air targets - low reliability, design complexity, one-time use.

The technical task of the proposed utility model is to eliminate the shortcomings of known simulators of air targets, increase lift, provide radar contrast and generate infrared radiation in a given range of the radiation spectrum.

The problem is achieved by the fact that a vertically flying target of a helicopter simulator, including a lifting device containing shells fastened together, inside

each shell has a rotor-motor installation with an electric motor and a screw mounted on its shaft, a frame on which power supplies, a control unit and stabilizing devices are mounted, a target made in the form of a conical skirt with a metallized outer surface and an infrared emitter, characterized in that in the lifting device an annular wing-shaped profile is mounted above each casing, a flat horizontal or conical reflective plane is placed under the propeller installation, m the crown in its upper part is equipped with a corner reflector, and the infrared emitter is located in the lower part of the conical skirt.

The installation of an annular conical (wing) profile and a horizontal (or conical shape) reflective plane provides a significant increase in the lifting force of the lifting apparatus. The reflective horizontal plane changes the direction of the air flow of the propeller installation in the direction of the annular wing, resulting in an increase in lift.

A corner reflector provides an increase in the radar contrast of the target itself, and an infrared emitter operating on hydrocarbon fuel provides a given spectrum of infrared radiation (IR radiation). The presence of a corner reflector allows in some cases to exclude metallization of the conical skirt. In order to reduce the thermal effect of the IR emitter on the target material, it is placed in the lower part of the conical skirt. The infrared emitter is equipped with an ignition and combustion control system.

The following graphic materials explain the essence of the proposed utility model.

Implementation of a utility model.

Vertically take-off target of a helicopter simulator, including a lifting device, figure 1, containing at least two shells 1 fastened together, inside each of which a rotor-motor installation is located, figure 2, with an electric motor 3, power sources 4 and mounted on the shaft of the electric motor 3 screw 5, frame 6, on which the control unit and stabilizing devices 7 are mounted (Fig. 1).

In the lifting apparatus, an annular wing profile 10 is installed above each casing 1, and a horizontal or conical-shaped reflective plane 11 is placed under the propeller installation, Fig. 2.

The target, figure 3, made in the form of a conical skirt 8, is equipped with a corner reflector 12, and an infrared emitter 9 is placed in its lower part. The infrared emitter has an ignition and combustion control system.

In order to ensure safety during operation of the propeller installation, the upper part of the wing profile 10 is closed by a protective net 13 (Fig. 2).

The operation of a vertically flying target of a helicopter simulator is as follows.

On the launch platform, a lifting device and, in fact, target 6 are placed. The lifting device is fastened with a halyard with a winch and a cable - with the target. The cable length is selected for reasons of the safe distance of the target from the lifting device.

At a distance (up to 5 km) from the launch platform, a mast with an antenna unfolds. Using a remote control, the launch of several lifting devices can be controlled simultaneously or separately.

When giving a command to start the lifting device, power from power sources 4 is supplied to the propeller-driven installations. Electric motors 3 unscrew the screws 5, the rotation of which creates a lifting force.

After reaching traction exceeding the mass of the lifting device, it breaks away from the launch platform and raises the target. A significant contribution to the increase in lifting force is made by the installation of an annular conical (wing profile) 10 and the placement of a horizontal reflective plane 11 under the propeller installation. A command is sent from the control unit to turn on the IR emitter 9, whose operation provides a spectrum of infrared radiation in a given range.

Using stabilizing devices, stabilization of the lifting apparatus in the longitudinal and transverse directions, as well as in the angle of rotation, is achieved.

At a given height (100-150 m), the lifting device freezes for one or two minutes, after which a command is issued from the control unit to turn off the propeller installation, the speed of the electric motors 3 is reduced and the lifting device smoothly lands.

In the process of lowering the lifting device with the help of a halyard and a winch, it is pulled to the launch platform for the purpose of reuse.
