Description

The utility model relates to the field of training devices, in particular to simulators for improving the 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:

the emergence of prerequisites for injury to a parachutist at the moment of his push from the springboard during a jump, especially in winter or rainy weather, due to the lack of an anti-slip surface on the springboard, as well as the absence of devices for gripping with hands at the free ends of the straps.

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 skills, ensuring increased training safety.

The technical result is achieved due to the fact that the parachutist simulator for improving landing skills contains a rectangular base with a protrusion made on one of its sides, characterized in that a stand with a hydraulic drive is mounted on the protrusion with the ability to change its height by a control signal, and the support the surface of the cabinet is made with a layer of anti-slip material, while in the center of the axis of the base, offset to the side opposite the protrusion, a niche is made, and on opposite sides of the base, adjacent to the side with the protrusion, guides are made along the niche, on which movable carriages are installed coaxially to each other with a hydraulic drive with the ability to move them along them according to a control signal, while telescopic poles are mounted on each of the mobile carriages with the ability to change their height according to a control signal, and between them, at the ends of the sides opposite from the connection with the mobile carriages, a crossbar is mounted, in the middle of which fastenings are installed 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, ensuring a reliable grip by the parachutist and preventing his rotation during landing, and on the other - a counterweight is mounted, which ensures that the U-shaped bracket with straps returns to its original position after the parachutist releases the holders for gripping with his hands.

Implementation of a utility model.

The claimed design of a parachutist simulator for improving landing 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 of anti-slip material , 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, from the control panel.

In the center of the axis of the base 1, offset to the opposite protrusion 2 side, 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 possibility of simulating , depending on the need, sand, stones or plowing.

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. From the bottom of the movable carriages 14, rollers are mounted (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, ensuring a reliable grip by the parachutist and preventing him from turning during landing, and on the other (21) a counterweight 24 is mounted, ensuring the return of the U-shaped bracket 20 with straps 22 in initial position after releasing the holders for gripping with hands 23 by the parachutist.

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 a signal from the training leader, the parachutist, using the holders for gripping with the hands 23, separates from the layering 4 of the supporting surface 5 and, having reached the front point of the swing amplitude, releases the holders for gripping with the hands 23 and lands on the simulating material 11 according to the rules established by the training leader 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.

Thus, the technical result of the claimed utility model, which consists in providing the possibility of creating a parachutist simulator for improving landing skills, ensuring increased safety of training, is achieved through the use of layer 5 of an anti-slip surface, preventing the parachutist from slipping when making a jump, as well as through the use of fasteners on bearings 19, straps 22 with holders for grip with hands 23, made with a distance from each other that ensures a reliable grip by the parachutist and prevents him from turning during landing.
