Description

The utility model relates to the field of training devices, in particular to simulators for improving the landing and splashdown skills of parachutists at different wind speeds.

Known from the prior art is a UNIFIED PARACHUTTER SIMULATOR [1], which is a structure made of metal structures, in the upper part of which a cargo compartment is mounted, which performs the function of improving the skills of placing paratroopers and separating them from the aircraft, as well as guide overpasses that allow paratroopers to jump one after another in cargo hatch, in the doors, as well as in the cargo hatch and doors.

The disadvantage of this technical solution is the lack of opportunity for parachutist trainees to improve their self-insurance skills when falling, due to the fact that after landing the connection between the trainees and the simulator does not stop, since the free ends of the parachute system models are hooked to the carabiners of the carriage, and they, in turn, are in monorail. In addition, there is no possibility of improving the landing skills of parachutists at different wind speeds or in calm conditions, due to the lack of constructive solutions for this.

The closest to the claimed utility model, adopted as a prototype, is the PARACHUTE SPRINGBOARD [2], containing three platforms mounted at different heights from the ground (in particular, 1 m, 1.5 m and 2 m) and a device for practicing skills in landing in a strong wind, which is a crossbar mounted on two pillars by means of a tenon connection, in the middle of which there is mounted a trapezoid with straps, the free ends of which are made with the possibility of attaching to them the free ends of the trainee's parachute suspension system.

The main problems of the prototype are:

lack of opportunity to improve the skills of parachutists landing on various ground surfaces (for example, sand, stones, plowing), as well as splashdown, due to the lack of appropriate landing surfaces;

the inability to improve the landing skills of parachutists at different wind speeds, due to the lack of ability to adjust the radius of movement of the parachutist relative to the crossbar during the flight, which affects the speed of his movement;

The purpose of a utility model is to eliminate the shortcomings of the prototype.

The technical result of the claimed utility model is to provide the possibility of creating a parachutist simulator for improving landing and splashdown skills, ensuring increased versatility of its use.

The technical result is achieved due to the fact that the parachutist simulator for improving landing and splashdown skills contains a rectangular base with a protrusion made on one of its sides, while a stand with a hydraulic drive is mounted on the protrusion, with the ability to change its height by a control signal, when In this case, in the center of the axis of the base, offset to the side opposite the protrusion, there is a niche, with the possibility of inserting a replaceable layer of the landing surface or a water tank into it, and on opposite sides of the base, adjacent to the side with the protrusion, guides are made along the niche, on which they are installed coaxially mobile carriages with a hydraulic drive to each other with the possibility of moving along them according to a control signal, while telescopic poles are mounted on each of the mobile carriages with the possibility of changing their height according to a control signal, and between them at the ends opposite from the connection with the movable carriages of the sides, a crossbar is mounted, in the middle of which there are fastenings on bearings with the possibility of their free rotation, to which two U-shaped brackets are welded, on one of which straps with holders for gripping with hands are installed at a distance from each other, and on the other a counterweight is mounted.

Implementation of a utility model.

The claimed design of a parachutist simulator for improving landing and splashdown skills (see Fig. 1) contains a rectangular base 1 with a protrusion 2 made on one of its sides, while a stand 3 is mounted on the protrusion 2, containing a supporting surface 4 with a layer 5, mounted on the movable part 6, and a stationary part 7 in the form of a guide box, on two opposite sides of which a hydraulic cylinder 8 is mounted, the rod 9 of which is connected to the movable part 6, and the drive is configured to change the height of the pedestal according to a control signal, for example, with control panel.

In the center of the axis of the base 1, offset to the opposite side of the protrusion 2, there is a niche 10, with the possibility of inserting into it a replaceable layer of the landing surface (see Fig. 2), containing a box 11 and a simulating material 12 inserted into it, the surface of which is made with the ability to imitate , depending on the need, sand, stones, plowed land or a water tank (see Fig. 3), the depth of which ensures the improvement of the parachutist’s splashdown skills.

On opposite sides of the base 1 (see Fig. 1), adjacent to the side with the protrusion 2, along the niche 10 there are guides 13 on which movable carriages 14 are installed coaxially to each other. Rollers are mounted on the movable carriages 14 from the bottom (in the figures not shown), with the possibility of their rotation, which are installed in the guides 13, ensuring unhindered movement of the movable carriages 14 along the guides 13. Attached to one side of each movable carriage 14 are rods 15 of hydraulic cylinders 16 mounted on the base 1, the drive of which is made with the possibility of synchronous control them using a control signal, for example, from a control panel.

In the center of each of the movable carriages 14, telescopic pillars 17 are mounted, designed to change their height by a control signal, for example, from a control panel using a hydraulic drive (not shown in the figures). Between the telescopic pillars 17, at the ends opposite from the connection with the movable carriages 14, a crossbar 18 is mounted, in the middle of which fastenings are installed on bearings 19 with the possibility of their free rotation, to which two U-shaped brackets 20, 21 are welded, on one of which (20 ) straps 22 are installed with holders for gripping with hands 23 at a distance from each other, and a counterweight 24 is mounted on the other (21).

The hydraulic drives of the moving part 6 of the pedestal 3, the movable carriages 14, and the telescopic poles 17 are designed to operate from a single power unit, for example, from an internal combustion engine (not shown in the figures).

The parachutist simulator is used to improve landing and splashdown skills as follows.

Before starting a lesson to improve the landing skills of parachutists, a removable layer of the landing surface is installed in niche 10 of the proposed design variant of the claimed utility model (see Fig. 2), the simulating material 12 of which corresponds to the soil of the area where the landing site for parachutists will be located when they perform a real parachute jump.

Then the power unit for controlling the hydraulic drives of the simulator is started.

After which, at the command of the lesson leader (see Fig. 1), the next parachutist climbs the telescopic ladder 25 to the pedestal 3, while the lesson leader, using the remote control, controls the hydraulic cylinders 8, lifts the parachutist to the required height in accordance with his height, and by controlling the hydraulic cylinders 16 regulates the radius of movement of the parachutist relative to the crossbar during his flight, thereby setting the wind speed necessary for training upon landing.

Then, at the signal from the training leader, the parachutist, using the holders for grip with the hands 23, separates from the layer 4 of the supporting surface 5 and, having reached the front point of the swing amplitude, releases the holders for the grip with the hands 23 and lands on the simulating material 11 according to the rules established by the leader of the training with self-belaying when falling . After the parachutist has released the hand grip holders 23, the U-shaped bracket with straps 20 returns to its original position under the influence of the counterweight 24. Subsequently, the training cycle is repeated with subsequent parachutists in the same sequence.

If it is necessary to improve the landing skills of parachutists, a water tank is installed in niche 10 (see Fig. 3). At the leader’s signal, the next parachutist rises to the supporting surface 4 (see Fig. 1), attaches the free ends of the parachute suspension system to the straps 22, while to ensure the possibility of improving the paratroopers’ splashdown skills, the lesson leader, using the control panel, raises the crossbar 18 to the required height, by controlling the corresponding hydraulic cylinders. Next, at the signal from the lesson leader, the parachutist is separated from stand 3, and the lesson leader, using the remote control, controlling the mobile carriages 14, moves the parachutist to the middle of the water tank. After which the parachutist, freeing himself from the parachute suspension system, performs splashdown while improving the relevant skills.

Thus, the technical result of the claimed utility model, which consists in providing the possibility of creating a parachutist simulator for improving landing and splashdown skills, ensuring increased versatility of its use, is achieved due to the fact that thanks to the use of hydraulic cylinders with hydraulic drives for moving mobile carriages 14, lifting and lowering the supporting surface 4, raising and lowering the telescopic pillars 17, a replaceable layer of the landing surface with different simulating material 12 and a water tank, it is possible to improve the landing skills of paratroopers of different heights, with landing on different soils, including splashdown, with different wind speed upon landing, which increases the versatility of the simulator.
