Description

2. Description of the utility model

2.1 The technical field to which the utility model belongs.

The proposed utility model relates to a modeling technique and can be used to simulate a complex phono-target environment in modeling the operation of aircraft equipment, as well as in training operators of this equipment.

2.2 prior art

Currently, a number of devices are known that are designed to simulate a complex phono-target environment when modeling the operation of aircraft equipment in order to control its technical characteristics or to train operators of this equipment.

So, the “Two-stage dynamic target simulator” is known (RF patent for utility model No. 156563 dated 05/28/2015, IPC G02B 26/02, G09B 9/00, F41A 33/02, F41G 3/26), containing among other elements several simulators targets, which are emitters of signals with adjustable radiation intensity, installed with the possibility of movement in azimuth, while at least one of the emitters of signals is installed with the possibility of additional movement in elevation, among other things, characterized in that the emitters are mounted on brackets located on a movable horizontal platform. The main disadvantage of this device is a limited set of simulated situations of the phono-target environment, which restriction is associated with the technical features of this product, allowing only two degrees of freedom in the movement of simulators

The closest to the proposed utility model is the device "Test bench" (RF Patent for the invention No. 2263869 of 02/11/2004, IPC F41G 3/26, G09B 9/08). This device incorporates a target simulator placement unit made in the form of a hemisphere, and the target simulator is equipped with two platforms located on both sides of the hemisphere with mirror symmetry relative to each other and pressed by magnetic attraction to each other. Platforms are capable of moving in a hemisphere in any direction. A signal emitter is located on a platform located on the inner side of the hemisphere. Moving a target is simulated by moving a two-platform target simulator in the hemisphere. The disadvantage of the described device is the need to accurately maintain the distance between the radiation receiver from the target simulator and the hemisphere on which it is placed, which limits the set of test modes, in addition, the description of the present invention involves a single target simulator, which limits the ability to simulate a complex phono-target environment.

5. Implementation of a utility model

A dynamic simulation stand with three-stage target simulators, proposed as a utility model, is carried out as follows.

The main functional elements of the proposed utility model are three-stage simulators of the goal, a diagram of one of which is presented in figure 1.

The three-stage target simulator includes an emitter installed on the platform (1) of the three-stage node of the turn-over, which, by signals from the control system, rotates along the channels “Turn-by-turn in elevation angle” (2) and “Turn-in by azimuth” (3) holds the longitudinal axis of the emitter aimed at the observer at any positions of the carriages of the target unit. Channel “Roll roll” (4) allows you to change the polarization of the emitter in the process, which extends the functionality of the proposed site of the target in comparison with the nodes of the target having a two-channel dovor.

The movement of the channels “Dot by azimuth”, “Dot by elevation” and “Dot by roll” is carried out using tracking drives. Each of the mentioned servo drives consists of a gear motor (5), which includes a bearing support, gearbox, electric motor, angular position sensor (6) with which the current position of the “Kren” channel and control system elements are measured, which provide control circuit closure and processing of driving signals. The selected drive layout provides high rigidity and accuracy of processing input signals with small dimensions, which is especially important in turnaround nodes.

The described simulators of the goal are integral parts of the dynamic simulation stand proposed as a useful model, the general scheme of which is shown in FIG. 2.

The proposed dynamic simulation stand is a movable platform that moves along rails (7) on wheels (8), and the operator working with the stand can set an arbitrary position of the platform relative to the observer before starting the simulation. On the described platform is the site of the placement of target simulators, made in the form of a flat structure of the following form.

The above simulators of the target (9) are installed on each of the two carriages of the Azimut channel (10), which on roller bearings (11) independently move along the azimuthal guide (12). The movement in the azimuthal plane (in the directions indicated by arrows in Fig. 2) is carried out using the following azimuth channel drives, each of which consists of a gear motor (13), the output gear of which engages with the azimuthal gear rack (14), the position sensor of the channel "Azimuth" (15), the output shaft of which is engaged with the gear rack through the backlash gear, and the elements of the control system that ensure the closure of the control loops and the processing of the driving signals.

The azimuthal guide is mounted on the carriage of the channel “Elevation angle” (16), which on roller roller bearings (17) move along the elevation angle guides (18). The movement in the elevation plane (in the directions indicated by arrows in Fig. 2) is carried out using two synchronously operating servo drives of the Elevation Angle channel, including gear motors (19), the output gears of which are engaged with the gear rails of the elevation angle (20) . On one of the carriages, a position sensor of the channel “Elevation angle” (21) is installed, the output shaft of which is engaged with the gear rack through a gear-backlash.

The site of placement of simulators of the target, made in the form of a flat design allows, unlike spherical, installation at any distance from the observer, which allows using one node to work out various test modes by moving the simulator along the test chamber

To balance the elevation channel, a counterweight (22) is used, which is connected to the azimuthal guide using 2 closed ropes (23) thrown through the upper (24) fixed and lower (25) rollers regulated by screw mechanisms (26) . Adjusting units allow you to maintain the tension of the cables without disengaging and re-locking the cable. The counterweight beam (27) has mechanisms for rolling (28) along the guides (29).

The counterbalance allows you to balance the imbalance of the channel "Elevation angle", which positively affects the working conditions of the servo drive, reducing the dynamic and static component of the positioning error, and also allows you to keep the static position of the target simulators in elevation without turning on the servo drive.
