Description

[0001] The invention relates to protective devices, in particular to devices for protecting equipment from the damaging effects of loitering munitions, used as additional (duplicate) protective means.

[0002] The prior art includes a CABIN WITH A DEVICE FOR PROTECTION AGAINST DROP-OFF EXPLOSIVE OBJECTS [RU 2826274 C1, publ. 09.09.2024], comprising a frame formed by a roof and walls, wherein a base made of high-strength metal is installed on the outer side of the frame on the roof by means of a connection that ensures the secure fastening of the base to the roof, a holder made of high-strength metal is mounted on top of the base, and the holder is connected to the base with the possibility of providing the formation of a gap that ensures the dispersion of the cumulative jet of the dropped cumulative explosive object, a bearing is mounted on the holder, on which a protective shell made of high-strength metal is installed, with the possibility of free rotation around its axis, a telescopic tube is mounted in the protective shell in the center of the axis of rotation, connected to the drive of the engine installed inside the cabin, and passing through the through holes,made in the center of the holder, base and roof, wherein on the outer surface of the protective shell there are ribs with a configuration that ensures the rebound of the dropped high-explosive explosive objects to the side when the protective shell rotates, and the telescopic tube, made with the possibility of ensuring a change in height by the amount of the gap between the base and the holder, is mounted with the possibility of ensuring the transmission of torque from the engine drive to the protective shell.

[0003] The main disadvantage of this analogue is the complexity of the design and the insufficient level of effectiveness of the equipment protection, expressed in its use only as protection against explosive objects dropped from above.

[0004] Also known from the prior art (adopted as a prototype) is SHIELDED ARMOR [RU 2655590 C1, publ. 28.05.2018], consisting of the main armor and a lattice screen attached to it at a certain distance, made in the form of a lattice of flat extended metal elements having a certain ratio of thickness and width, attached at a certain distance from each other and connected to each other by ties attached at a certain distance from each other, characterized in that the elements are made with a profile thickness of 2 to 12 mm, a thickness to width ratio of 0.1-1, a linear weight of at least 0.5 kg / m, while the smallest distance between the elements is less than the diameter of the cumulative grenade, said elements are connected to each other by at least two flexible ties attached above the upper element, and the distance from the front side of the elements to the main armor is at least 150 mm.

[0005] The main technical problem of the prototype is the lack of mechanisms to ensure the rejection of explosive objects dropped from above, as well as the lack of mechanisms to increase the distance of the explosion of a loitering munition from the surface or the protection of equipment.

[0006] The objective of the invention is to eliminate the shortcomings of the prototype.

[0007] The technical result of the invention consists in providing the possibility of creating an additional device for protecting equipment from the effects of loitering munitions, increasing the arsenal of means for countering unmanned aerial vehicles used as loitering munitions, and also increasing the effectiveness of equipment protection.

[0008] The specified technical result is achieved due to the fact that the device for protecting equipment from the effects of loitering munitions contains a base made with the possibility of providing attachment to the surface of the equipment or the shielding protection of the equipment, the base is connected to a holder made in the form of a pipe on which a cartridge with a protective coating is installed using fixing means, and the base is connected to a box inside which a drive mechanism is mounted, connected to the holder with the possibility of ensuring its rotation, ejection means are mounted on the holder, made with the possibility of ensuring the ejection of a cartridge with a protective coating by a remote control signal, the cartridge with a protective coating contains a washer, along the perimeter of which ears are mounted, connected to cables, at the ends of which weights are mounted, protective coatings are installed between adjacent cables, and the cables,the weights and protective coverings are folded by means of a locking means designed to ensure the release and deployment of the protective coverings by means of centrifugal force.

[0009] In a particular case, the protective coverings are made of metal mesh material.

[0010] In this particular case, the holder is made telescopic.

[0011] In a particular case, the weights are made in the form of metal spherical elements.

[0012] In a particular case, the ejection device is made in the form of a spring mechanism.

[0013] In a particular case, the fixing means is made in the form of a fixing plastic tape with characteristics designed to ensure its rupture when the maximum rotation speed of the holder is reached.

[0014] In a particular case, the fixing means is made in the form of a plastic container with cuts that ensure its opening due to centrifugal force when the holder reaches its maximum rotation speed.

[0020] The development trend of unmanned aerial vehicles, their relative affordability, and ease of manufacture are driving their widespread use as loitering munitions. Analysis of their use shows that each piece of equipment is actively hunted, thus spurring the search for solutions to counteract the effects of loitering munitions.

[0021] The design variant within the framework of the application for the proposed invention is an additional means of protection used along with the shielding protection of equipment installed in the zone most vulnerable to equipment, electronic warfare means and means of laser blinding and incapacitation by overloading the video channel of the technical vision means of unmanned aerial vehicles used as loitering munitions.

[0022] Implementation of the invention

[0023] A device for protecting equipment from the effects of loitering munitions (see Figs. 1, 2) comprises a base 1, configured to be secured to the surface of the equipment or to the shielding of the equipment. For this purpose, the base 1 comprises fixing means. These fixing means are implemented in the form of magnetic fasteners (capable of ensuring secure attachment to a flat metal supporting surface of the equipment) and / or mechanical clamps (capable of securing to the shielding of the equipment).

[0024] Base 1 is connected to holder 2, which is shaped like a tube. Holder 2 is telescopic, and a cartridge 3 with a protective coating is mounted on it using locking means. Base 1 is connected to box 4, which houses a drive mechanism, implemented as an electric motor, which is connected to holder 2 to ensure its rotation.

[0025] Mounted on holder 2 is an ejection device capable of ejecting cartridge 3 with a protective coating upon a remote control signal. The ejection device is a spring-loaded mechanism mounted within holder 2, which is connected to cartridge 3 via hooks inserted through longitudinal guide opening 5.

[0026] Cartridge 3 with a protective coating comprises a washer 6, along the perimeter of which ears 7 are mounted, connected to cables 8, at the ends of which metal weights 9 in the form of spherical elements are mounted. Protective coatings 10 made of a metal mesh material are installed between adjacent cables 8, wherein the cables 8, weights 9 and protective coatings 10 are folded due to a locking means 11, configured to ensure the release and deployment of protective coatings 10 due to the centrifugal force created by the rotation of the holder 2.

[0027] In one embodiment of the proposed invention, the fixing means 11 is made in the form of a fixing plastic tape (not shown in the figures) with characteristics (thickness and width) made with the possibility of ensuring its rupture due to the tension arising from the action of the fastened elements under the action of centrifugal force, when the maximum rotational speed of the holder 2 is reached.

[0028] In another embodiment of the proposed invention, the fixing means 11 is made in the form of a plastic container 12 with cuts that ensure its opening due to centrifugal force when the maximum rotation speed of the holder 2 is reached. In the upper part of the container 12, openings 13 are made for passing cables 8 through them into the internal cavity.

[0029] Also, to ensure uninterrupted operation of the device, the holder 2 can be designed with the possibility of installing several cartridges 3 with protective coatings in it, ensuring their sequential operation (when a working cartridge is ejected, the next one starts working).

[0030] In one embodiment of the proposed invention, the device is equipped with a means for detecting an approaching loitering munition with a mechanism for automatically activating the electric drive for rotating the holder 2.

[0031] The device for protecting equipment from the effects of loitering munitions is used as follows.

[0032] The design variant of the proposed invention is installed using the fasteners included in the device on the surface of the equipment (see Fig. 3) or on the existing shielding protection of the equipment.

[0033] If there is a threat of exposure to a loitering munition, the proposed device is switched to the operating mode using a remote control by turning on the electric drive.

[0034] Then, holder 2 begins to rotate, reaching the maximum preset speed. Due to the centrifugal force generated by the rotation of holder 2, the retaining element 11 breaks (if designed as a plastic strip) or disintegrates into its component parts (if designed as a plastic container with slits), releasing weights 9, which tension cables 8, thereby straightening protective coatings 10.

[0035] When a loitering munition enters the range, a remote control signal activates the ejection device, which ejects a cartridge with a protective coating onto the loitering munition, thereby increasing its response range.

[0036] In the event that the enemy uses a loitering munition based on the principle of dropping an explosive object from above, rotating protective coatings 10 ensure that the explosive object bounces (throws back) to the side.

[0037] The presence in the proposed device of a cartridge with protective coatings with the implementation of their rotation and ejection (ejection) onto an approaching loitering munition contributes to increasing the protection of equipment, since the distance of the explosion from the equipment increases, as well as the throwing to the side of the explosive object when it is dropped from above.

[0038] The telescopic design of the holder also contributes to the protection of the equipment, since it makes it possible to increase the area protection by combining the installation of several devices at different levels of rotating protective covers.

[0039] Example of the implementation of the proposed invention

[0040] In 2024, an experimental prototype of a device partially implementing the essential features of the proposed device was created. The prototype was mounted on the rear of a pickup truck. A Mavik-type quadcopter was used to simulate an attack loitering munition. The loitering munition was deployed from the rear of the vehicle, following the vehicle's direction of travel, using the "hunter-like" principle. Approximately 3.5 meters from the vehicle, the ejection device was activated, causing the simulated loitering munition to be shot down by protective coatings. It was determined that the simulated "explosion" of the munition occurred at a distance of 3 meters from the vehicle, increasing its protection.

[0041] Thus, the technical result, which consists in providing the possibility of creating an additional device for protecting equipment from the effects of loitering munitions, increasing the arsenal of means for countering unmanned aerial vehicles used as loitering munitions, and also increasing the effectiveness of the protection of equipment, is achieved through the implementation of the proposed invention.
