Description

Counter-drone munition with capes

[0001] The invention relates to weapons, specifically to means for the mechanical destruction of small objects using capes. The invention is applicable to countering terrorism by ensuring the security of stationary objects, vehicles, and public events in open areas.

[0002] The closest analogue to the claimed technical solution is a munition with a cape for countering aerial drones, described in Russian Patent No. 2819119, published May 14, 2024. The device comprises a housing open at the front, having an imaginary longitudinal axis, and a closed barrel at the rear, connected to the housing or forming part of the housing, with the barrel muzzle facing forward. It also has a "cassette" located on the imaginary longitudinal axis and containing a piston. The piston faces rearward and is housed in the barrel. It also has an air-detonating means for the expelling charge and the expelling charge located in the barrel.

[0003] The device also includes a cape. The cartridge comprises first and second jaws, perpendicular to an imaginary longitudinal axis and connected to a rod, where the outer diameter of the rod is smaller than the outer diameters of the jaws. The first jaw is located anterior to the second jaw. The cape contains a ring, cape weights, and cape threads. The cape is located between the first and second jaws. The cape weights are arranged around an imaginary longitudinal axis. Each cape weight is equipped with a cape thread. Each cape thread is attached to the corresponding cape weight at its first end. The ring is located outside the rod. The second end of each cape thread is attached to the ring. Each cape thread is compactly packed so that it can be straightened when pulled by its second end. The ammunition has a cover at the front.

[0004] When the munition is fired, it begins to rotate around an imaginary longitudinal axis. The weights are pressed into the body and cover from the inside. The cartridge, like the cover, can slide relative to the body along the longitudinal axis. When the expelling charge detonates, the cover and cartridge slide forward relative to the body. The front ends of the weights, held by the cover, and the rear ends of the weights, held by the body, simultaneously release radially and exit the cartridge from the compartment formed on its core by the first and second jaws. The weights pull the threads. The cape unfolds. It flies forward and strikes an aerial drone.

[0005] In the known design of an expanding munition, which provides for the simultaneous release of the front and rear ends of the weights from a single compartment, a limited number of threaded weights can be placed in the plane of the joint between the body and the cover. This is a drawback of the known munition. The lethality of this number of threaded weights is limited. The probability of their hitting the target is low.

[0006] The purpose of this technical solution is to increase shooting efficiency.

[0007] To solve the technical problem and achieve the desired technical result, the design of a known device was modified. The known munition, with a cape for countering aerial drones, comprises a front-opening body with an imaginary longitudinal axis. A closed-rear barrel, connected to the body or forming part of the body, is located forward. It also contains a cartridge located on the imaginary longitudinal axis and containing a piston. The piston faces rearward and is housed in the barrel. It also has an air-detonating device for the expelling charge and the expelling charge located in the barrel.

[0008] The device also includes a first cape. The cassette comprises first and second jaws, perpendicular to an imaginary longitudinal axis and connected to a rod, wherein the outer diameter of the rod is smaller than the outer diameters of the jaws. The first jaw is located anterior to the second jaw. The first cape contains a first ring, first cape weights, and first cape threads. The first cape is located between the first and second jaws. The first cape weights are arranged around an imaginary longitudinal axis. Each first cape weight is equipped with a first cape thread. Each first cape thread is attached to the corresponding first cape weight at its first end. The first ring is located outside the rod. The second end of each first cape thread is attached to the first ring. Each first cape thread is compactly arranged so that it can straighten when pulled by its second end.

[0009] A third cheek is inserted behind the second cheek, parallel to the second cheek and connected to the rod. A second cape is also inserted between the second and third cheeks, containing a second ring, the weights of the second cape, and the threads of the second cape. The weights of the second cape are arranged around an imaginary longitudinal axis. Each weight of the second cape is equipped with a thread of the second cape. Each thread of the second cape is attached to the corresponding weight of the second cape at its first end. The second ring is located outside the rod. The second end of each thread of the second cape is attached to the second ring. Each thread of the second cape is compactly arranged so that it can be straightened when pulled by its second end. The weights of the capes are located inside the body.

[0010] In addition, the gap between adjacent cheeks may be less than the largest overall dimension of the cross-section of the load, made by an imaginary plane passing through an imaginary longitudinal axis.

[0011] In addition, the distance in the direction of the imaginary longitudinal axis from the front end of the second cheek to the front part of the body may be equal to or even exceed the depth of the piston in the barrel.

[0012] In addition, the cape can have at least three weights.

[0013] Additionally, grooves parallel to the imaginary longitudinal axis can be made on the inner surface of the housing. The grooves are then open at the front, with each load positioned within a groove.

[0014] In addition, a protrusion located in the groove can be made on the outer part of the rear cheek.

[0015] In addition, the body and the cassette can be connected by a flexible connection.

[0016] In addition, the rod between the cheeks can have recesses, with each load located in a recess.

[0017] Moreover, in the design with recesses on the rod, an imaginary direction segment connects the center of mass of each load with an imaginary longitudinal axis, the orthogonal projections of all direction segments onto a plane perpendicular to the imaginary longitudinal axis can be uniformly distributed around the imaginary longitudinal axis.

[0018] In addition, the thread can be made of aromatic polyamide material.

[0019] The technical result that this technical solution is aimed at achieving is to increase the probability of hitting an aerial drone.

[0020] The modified design of the device increases the number of compartments between the jaws on the cartridge rod, which contain the threaded payloads. These compartments are located inside the casing, with the casing capable of opening them sequentially upon detonation of the expelling charge. This also increases the total number of threaded payloads in the munition. When the casing shifts relative to the cartridge due to detonation of the expelling charge, the payloads exit the cartridge, forming not one, as in its closest analogue, but two. The additional number of threaded payloads increases the probability of hitting a drone. Figure 1

The piston has exited the barrel. Figure 12

[0033] This is the first frame of a schematic sequence depicting the operation of a munition with capes for destroying aerial drones. The munition (as part of a "shot" from a hand-held anti-tank grenade launcher) approaches its target—an aerial drone—to destroy it. Figure 14

[0034] This is the second frame of a schematic sequence depicting the operation of the munition. The propellant charge has detonated, the weights of the capes fly apart, the cartridge has been removed, and the packed parachute falls out of the casing. Figure 15

[0035] Depicts a view from an aerial drone of an approaching munition along the munition's axis. The dotted lines indicate the positions of the strings with the weights after all the covers are fully deployed. Figure 16

[0036] Shows a view from an aerial drone of an approaching munition along the munition's axis. The arrangement of the weights and the threads of the capes differs from that shown in [image]. Figure 17

[0037] This is the third frame of a schematic sequence depicting the munition's operation. The payloads are scattered across the entire length of the strings, fully deploying the flaps. Three flaps missed the target. Two flaps, from the fourth and fifth flaps, made contact with the drone. The parachute is deployed and opens. Figure 18

[0038] This is the fourth frame of a schematic sequence depicting the munition's operation. The threads of two capes are wrapped around the drone's body. The drone has become inoperable and is falling. The sixth cape's threads are caught in the fourth and fifth capes and are falling down with them. The rear and front parts of the munition descend via parachute. The composition burns, creating a smoke trail.

[0039] The counter-drone munition depicted in Figures 2 and 3 comprises a hollow body 1. Body 1 is open at the front and has an imaginary longitudinal axis 2. Inside body 1 is a barrel 5, connected to body 1 by a thread. Barrel 5 is a durable metal tube. Muzzle 6 of barrel 5 faces forward. The rear of barrel 5 is closed. Body 1 is closed at the front by cartridge 4. Part of the cartridge is piston 3. Piston 3 is directed rearward. Piston 3 is located in barrel 5.

[0040] The ammunition contains a means for air-detonating the expelling charge, which is a distance tube 7 of an artillery shell, known from the prior art. Distance tube 7 is screwed into barrel 5, closing it at the rear. A distance ring 8 with a scale is part of distance tube 7. A propellant expelling charge 9 is located in barrel 5 near distance tube 7. An axial opening 10 is made in cartridge 4, containing smoke-generating composition 17. Cartridge 4 is closed at the front by a ballistic tip 11.

[0041] A through axial hole is made in piston 3, in which a highly flammable composition 12 is fixed. A smoke-forming composition 17 is pressed against the opposite end of this hole with composition 12, facing inside cassette 4. Composition 12 has high strength and strong adhesion to the walls of the hole, which excludes its mechanical destruction due to high pressure in barrel 5, arising after ignition of expelling charge 9.

[0042] Parallel cheeks are formed on cassette 4: for example, the first (front) 18, the second 19, and the third 20. The cheeks are perpendicular to an imaginary longitudinal axis 2 and are connected by rod 21. The outer diameter of rod 21 is smaller than the outer diameters of the cheeks. Rod 21 is made in the form of a cylindrical part.

[0043] The first cape is located between the first 18 and second 19 cheeks. The second cape is located between the second 19 and third 20 cheeks. The remaining capes are located similarly. Each cape contains a ring 22, eight weights 23 and eight connecting threads 24 made of aromatic polyamide material. The weights 23 are located around an imaginary longitudinal axis 2. A thread 24 is attached to each weight 23 by its first end. Each ring 22 is located outside the rod 21. The second end 26 of each thread 24 of the corresponding cape is attached to the ring 22 by a knot 25. The gap between adjacent cheeks is less than the largest overall dimension of the cross-section of the weight 23, made by any imaginary plane passing through the imaginary longitudinal axis 2. Such a cross-section of the upper depicted weight of the first cape is shown in . The weights of all capes are located inside the body 1.

[0044] On the inner surface of the housing 1 there are grooves 33, parallel to the imaginary longitudinal axis 2 and open at the front. Each weight 23 is located in the corresponding groove 33. The grooves 33 organize the arrangement of the weights 23 in the housing 1. In addition, on the outer part of all the cheeks there are projections 34, located in the corresponding grooves 33 of the housing 1. The projections 34 prevent the mutual rotation of the housing 1 and the cassette 4 about the axis 2. In the first (front) cheek there are openings 27 for the release of smoke, created by the smoke-generating composition 17, out of the cassette 4. The distance in the direction of the imaginary longitudinal axis 2 from the front end of the second cheek 19 to the front part of the housing 1 slightly exceeds the depth of the location of the piston 3 in the barrel 5.

[0045] Between the rear part of the hollow body 1 and the rear part of the cassette 4, a folded parachute 35 is located inside the body. The parachute 35 is connected to the body 1 by a cable 36. The cassette 4 is also connected to the body by a cable 37, which is a flexible connection. One of the folds of the cable 37 is located between the parachute 35 and the rear part of the body 1. In the rear part of the body 1, plugs 38 made of elastic material are made.

[0046] The munition delivery system is a rocket engine with a booster propellant charge. It consists of a nozzle assembly 40, a booster propellant charge 41, a stabilizer with fins 42, and a turbine 43. The booster propellant charge is not shown. The stabilizer fins 42 are shown open.

[0047] The cross-section of the load 23 is shown in . It is shaped like a flat cylinder, with a recess 45 in the central portion of the left end. A thread 23 is compactly arranged in recess 45 and can be straightened by pulling its second end 26. The first end of the thread 24 is attached to the load 23 by means of a knot 46. A circumferential groove 47 is formed on the cylindrical surface of the load 23. When the cassette 4 is equipped with caps, a section of the ring 22 (and 2) is placed in this groove.

[0048] A front view of the assembled cape with weights 23, threads 24 and straightened ring 22 before it was placed in cassette 4 is shown in.

[0049] A similar design of a munition with capes for destroying aerial drones is shown in Figures 7 and 8. Its design differs from the one described above in the elements that organize the arrangement of loads 23 in body 1.

[0050] On the rod 21 between the cheeks there are depressions 15 (and 7). Each load 23 of the cape is located in the depression 15. The number of depressions 15 is equal to the number of loads 23 of each cape. Each load 23 of the cape is located between its corresponding depression 15 and the inner surface of the body 1. An imaginary segment-direction 14 can be drawn from the center of mass 13 of each load 23 to the imaginary longitudinal axis 2. The segment-direction 14 is designated by a line of dots, and its ends are marked with the Greek letters y and 8. The orthogonal projections of all segments-directions 14 of the cassette onto a plane perpendicular to the imaginary longitudinal axis 2 are uniformly distributed around the imaginary longitudinal axis 2.

[0051] A simpler design of counter-drone ammunition with capes exists. The ammunition is part of the underbarrel grenade launcher's "shot" and is located in its front section. The ammunition comprises a hollow body 1 (and 10) and has an imaginary longitudinal axis 2. Inside body 1 is barrel 5, which is part of body 1. The muzzle 6 of barrel 5 faces forward. Barrel 5 houses expelling charge 9. Body 1 houses cartridge 4, with piston 3 fixed to the rear. Piston 3 faces rearward. Piston 3 is located in barrel 5.

[0052] Inside the housing 1, in its rear part, there is a means for air detonation of the expelling charge - a connecting channel 52, a powder tube 50 and a firecracker 53. The housing of the powder tube 50 contains a powder composition designed to transfer fire from the connecting channel 52 through a circumferential channel to the igniting part in the form of a powder firecracker 53 and then to the expelling charge 9. The initial 54 and final 55 parts of the circumferential channel are shown in the section on . The circumferential channel itself has the shape of a semicircle, is located in a plane perpendicular to the imaginary longitudinal axis 2 and is located behind the plane of the section. The powder tube 50 is adjusted by the manufacturer for a specific time of ignition of the expelling charge 9 after firing the ammunition. The distance in the case of a shot in the horizontal direction, after passing which the cape becomes completely straightened, is indicated on the nose fairing 56 of the ammunition. In the rear part of the housing 1 there are openings closed with plugs 57.

[0053] The ammunition delivery system is chamber 63, secured to the rear of body 1, filled with propellant powder charge 64 and primer 65. The rear wall of chamber 63 contains openings 66 for the release of propellant gas jets. A band 67 with leading protrusions corresponding to the spiral grooves in the grenade launcher barrel is used to rotate the ammunition along its flight path. A groove 68 is provided to secure body 1 of the ammunition in the barrel of the underbarrel grenade launcher before firing. The remaining components of the ammunition are identical to those shown in Figures 2 and 3.

[0054] The device operates as follows. The ammunition shown in [figure 1] is fired in the direction of aerial drone 70 () when the point of full cape deployment is correctly selected (set by rotating distance ring 8 () to the desired value on the scale) and the aiming point. If the elevation angle during firing is greater than 30 degrees, the shooter's back and the back of his legs are protected from the grenade launcher's flame by a fire-protective cape. When fired, the ammunition begins to rotate in flight. A radial force acts on each weight 23, pressing it into the corresponding groove 33 of body 1. At the designated point in the ammunition's flight trajectory, directly in front of the drone, the cape must be fully deployed. To achieve this, distance tube 7 is triggered at some distance before this point, creating a beam of fire directed at expelling charge 9 and igniting it. Explosive charge 9 creates excess gas pressure 71 () in barrel 5.The flammable composition 12 is ignited by the burning expelling charge 9 and burns inside the piston 3.

[0055] Piston 3 and barrel 5, under the action of gas pressure 71, begin to move with great acceleration in opposite directions relative to each other along axis 2. Piston 3 is connected to cassette 4, and barrel 5 is connected to body 1. Accordingly, body 1 and cassette 4 also move with great acceleration in opposite directions relative to each other. Since the distance in the direction of the imaginary longitudinal axis 2 from the front end of the second cheek 19 to the front part of body 1 (this distance is equal to the length of the projections 72 on the front part of cassette 4) slightly exceeds the depth of piston 3 in barrel 5, this accelerated movement continues only until the moment when piston 3 leaves muzzle 6 of barrel 5.

[0056] After piston 3 exits muzzle 6 of barrel 5, gases escape into the rear of housing 1. Plugs 38 are ejected from housing 1 by the increased pressure, after which the pressure in housing 1 drops sharply. The movement of housing 1 relative to cartridge 4 becomes virtually uniform. Accordingly, the caps are equidistant from each other after ejection.

[0057] The front edge of the housing 1, moving uniformly backwards relative to the cassette 4, exposes more and more of the weights 23 of the capes, placed between the cheeks in the cassette 4. The munition is depicted at the moment when only the weights 23 of three capes have exposed themselves. The weights 23, no longer held by the housing 1 and its grooves 33, stop rotating around the imaginary axis 2 and move outward from the cassette 4. The moments in time when the weights 23 of each cape are released from the cassette 4 are different for each cape. Accordingly, due to the rotation of the cassette 4, the angles relative to the thread 24 of the first weight 23 to exit the cassette 4 (), at which the threads 24 of the cape fly towards the target, are also different.

[0058] At the moment when the weights 23 of the first cape are completely released from the cassette 4, this cape leaves the edge of the housing 1 and then moves uniformly, without acceleration. The weights of the second cape leave the cassette an instant later. Due to the rotation of the cassette 4, the second cape is rotated relative to the first by a small angle. This angle may be formed by the thread 24 of the weight 23 of the first cape, designated al (), and the thread 24 of the weight 23 of the second cape, designated b1. It may also be a different angle. For example, the angle formed by the thread 24 () of the weight 23 of the first cape, designated al, and the thread 24 of the weight 23 of the second cape, designated b1. The power of the expelling charge 9 (), the intensity of its combustion and, accordingly, the speed with which the body 1 () moves back, are selected in such a way that all these angles of all weights 23 and all capes of the ammunition ensure uniform coverage of the striking area with threads 24.Also, the power of the expelling charge 9 and the intensity of its combustion are selected in such a way that each subsequent cape exiting the cassette 4 does not fall on the imaginary plane of the previous cape that has already exited the cassette 4.

[0059] Since the gap between adjacent cheeks of cassette 4 is less than the largest overall dimension of the cross-section of load 23, made by an imaginary plane passing through imaginary longitudinal axis 2, loads 23 before exiting cassette 4 do not have the opportunity to rotate relative to axes perpendicular to imaginary longitudinal axis 2. In a non-inertial rotating coordinate system associated with cassette 4, their centers of mass perform translational motion with a constant speed in a plane perpendicular to imaginary longitudinal axis 2, directed outward from the compartment between the cheeks.

[0060] A longitudinal section of the munition with counter-drone capes is shown at a subsequent moment in time compared to the moment shown in . All capes from cartridge 4 are released by the front edge of the housing. Housing 1 () and cartridge 4 () have moved away from each other at a considerable distance and are connected only by cable 37. Weights 23 of all six capes fly apart, each in its own direction. At the same time, in the inertial coordinate system, they rotate relative to their longitudinal axes at a frequency equal to the rotational frequency of the munition in flight. Together with cartridge 4, weights 23 fly forward toward the target. Smoke-generating composition 17, meanwhile, has ignited due to the flammable composition 12 () pressed against it and creates smoke that accumulates in opening 10 inside cartridge 4 and ballistic tip 11. After a moment, cable 37 will become taut and pull cartridge 4 from the central region of the capes.

[0061] Figures 14, 17, and 18 show a schematic diagram of how a munition with capes operates when engaging an aerial drone. The first frame of this sequence shows the munition (as part of a hand-held anti-tank grenade launcher round) approaching the aerial drone 70 to engage it. The gunner aimed the munition at the target, aiming slightly below it, rather than precisely.

[0062] In the second frame, the expelling charge 9 () detonates, the munition opens, and the 23 cape loads fly apart. For greater clarity, the distances between the capes along the imaginary longitudinal axis 2 are shown at greater intervals than they were in the cassette 4. Cassette 1 (), due to its greater mass, used cable 37 to pull cassette 4 back from the interior of the deploying capes a considerable distance. Upon exiting cassette 1, cable 37 also pulled cable 36 and parachute 35 attached to it. Parachute 35 began to unfold.

[0063] The view from the drone's perspective of the approaching munition along the munition's axis is shown at the moment depicted in . The dotted lines show the positions of the strings with the weights at a moment that occurs somewhat later, after all the covers have fully unfolded. The weights in the figure have designations consisting of two symbols: a letter and a number. The covers are designated by the letters of the Latin alphabet from a to f. The number of the load in the cover is indicated by the numbers from 1 to 8. The designations for the eighth and first loads of all the covers in the figure are listed. Further along the circle, only the designations of the first cover's loads are listed.

[0064] The weights of the 23 capes can be ejected from the cassette 4 at different angles. One variant is shown in . The weights of only two capes, the first (a) and the second (b), are indicated. As in the variant shown in , the threads 24 cover the entire affected area.

[0065] In the third frame of the schematic sequence depicting the munition's operation, weights 23 have spread out to the sides along the entire length of their threads 24, forming six fully extended capes. The first three capes, a, b, and c, failed to lock onto the target. Two threads from the fourth (d) and fifth (e) capes made contact with the drone. Moreover, the thread of weight d8 caught on the drone's body, and the thread of weight e8 entangled the propeller. The destruction diagram is shown in [image].

[0066] In the fourth frame, the threads of two capes are wrapped around the drone's body. The drone has become inoperable and is falling. The sixth cape (f) is caught by its threads on the fourth and fifth capes and is falling with them. The rear and front parts of the munition, attached to parachute 35, descend downwards without causing any harm to personnel, mobile equipment, or ground targets. Smoke-generating compound 17 () burns, creating a noticeable smoke trail in the sky. This trail makes it much easier for other shooters to detect the aerial drone and engage it if the first shot fails. The smoke trail also helps personnel avoid injury from falling projectile components and from the damaged drone.

[0067] A differently designed munition with capes for engaging flying drones, shown in Figures 7 and 8, operates similarly. However, there are some differences in how it deploys and how payloads 23 are ejected from cartridge 4.

[0068] Due to the action of the propellant gases, the housing 1 and the cartridge 4 move in opposite directions relative to each other with high acceleration. Housing 1 opens one after another the areas between the cheeks in which the weights 23 are placed. In the non-inertial rotating coordinate system associated with the cartridge 4, each weight 23, due to its accelerated forward movement together with the cartridge 4, experiences a longitudinal inertial force directed rearward and pressing it against the cheek located behind it. Also in this coordinate system, each weight 23 experiences a centrifugal force directed outward from the imaginary longitudinal axis 2 (the axis of rotation of the ammunition). The magnitude of the static friction force arising in this contact from the action of the longitudinal inertial force in the radial direction is equal to the magnitude of the centrifugal force. As a result, the weights 23 do not shift relative to the cheek and continue to rotate with it.

[0069] But the accelerated motion of the cartridge 4 and the housing 1 continues only until the moment when the piston 3 leaves the barrel 5 and when the significant after-effect of the powder gases on the rear parts of the cartridge 4 and the piston 3 ceases. At this moment, the force of static friction disappears, and all the weights 23 of all the capes, which the housing 1 has opened by this moment, simultaneously begin to move outward along a tangent to the circle of their rotation from the recesses 15 (), in which each of them is located. Since the projections of all the segments-directions 14 on the plane perpendicular to the imaginary longitudinal axis 2 are uniformly distributed around this axis, the projections of the recesses 15 and the threads 24 () of the straightening capes are also uniformly distributed around axis 2.

[0070] The arrangement of threads 24 in the open cape may be as shown in the picture or in the picture, or may be different. This or another arrangement of threads 24 in the open cape is determined by the arrangement of recesses 15 () on rod 21 of cassette 4.

[0071] A simpler counter-drone munition with capes, shown in Figure 10, which is part of the underbarrel grenade launcher's "shot," operates as follows. The shooter determines the distance to the drone visually or using a rangefinder. Based on the determined distance, the shooter selects the appropriately marked munition on the nose cone 56 from among the available ammunition. If no munition with the required range is available, the shooter selects a munition with a shorter range, keeping in mind that the deployed cape can hit the drone from several dozen meters away.

[0072] The shooter then loads the ammunition into the grenade launcher, selects an aiming point ahead (in the case of a moving drone) and above the drone, and fires. The firing pin of the underbarrel grenade launcher breaks primer 65 (). The beam of fire from it ignites propellant powder charge 64, generating propellant gases. Excess pressure is created in chamber 63, and the gases escape through openings 66 into the portion of the grenade launcher barrel covered by the ammunition. The resulting excess pressure from the propellant gases propels the ammunition forward toward the target. The leading lugs of band 67, sliding in the rifling of the grenade launcher barrel, twist the ammunition around an imaginary longitudinal axis 2.

[0073] When burning, propellant charge 64 ignites the propellant mixture in connecting channel 52. For a certain period of time, the fire moves along the circumferential channel from its initial portion 54 to its final portion 55. The fire then passes to propellant charge 53, which ignites propelling charge 9. By this time, the ammunition has flown to the target at the distance necessary for the cap to fully deploy. Accelerated movement of body 1 and cartridge 4 occurs in opposite directions. The deployment of the capes and the process of hitting the drone with the underbarrel grenade launcher ammunition, shown in Fig. 10, is similar to the operation of the ammunition shown in Figs. 3, 11, and 18.

[0074] The claimed device can be used on a permanent basis to counter terrorism, ensuring the security of stationary facilities, vehicles, and public events in open areas. It can also be temporarily deployed in combat during military operations. When repelling a swarm of aerial drones, the device is used for a remotely controlled automatic weapon coupled with a fire control system. It is most successfully applied to drones with a flight program capable of executing without operator radio control or the use of radio navigation systems, as well as to radio-controlled drones with automatic target acquisition under an electronic warfare dome. The device can also be successfully used to engage drones controlled via fiber optics.

[0075] The invention has been disclosed above with reference to specific embodiments. Other embodiments of the invention may be apparent to those skilled in the art without altering its essence as disclosed herein. Accordingly, the invention should be considered limited in scope only by the following claims.

[0076] No
