Description

Interception device for interception of unmanned aerial vehicles

The present invention relates to an interceptor for intercepting unmanned aerial objects, in particular drones, such as quadrocopter and the like, with a plurality of guide elements, which are inclined with respect to a longitudinal axis of the interceptor and distributed circumferentially about the longitudinal axis, and with a network recording, wherein the guide elements are circumferentially distributed around the net receiving around.

An interception device which is provided as an attachment module for a gas pressure weapon, the Applicant has already proposed in the earlier application DE 10 2016 1 1 1 563.0. In the attachment module proposed there, the guide elements are embodied as fluid outlet lines, a projectile being accommodated in each run-like fluid outlet line, and the projectiles can be fired substantially simultaneously in the axial direction of the respective run, in order to shoot a net in which an unmanned flying object is in Ground proximity can be caught. Since the projectiles are received in the run-like fluid outlet lines, also connecting elements, such as cords or the like, with which the safety net is connected to the projectiles, at least partially run into the runs. When accelerating the projectiles out there is a risk that the synchronous firing of the projectiles is affected if the arranged in the firing direction in front of the projectile cord tangles or otherwise affects the movement of the projectile. The object of the invention is therefore to provide an interceptor in which the above disadvantages can be avoided.

To achieve this object, an interceptor for intercepting unmanned aerial vehicles, in particular drones, such as quadrocopter and the like, proposed with a plurality of guide elements, which are inclined with respect to a longitudinal axis of the interceptor and distributed circumferentially about the longitudinal axis, a network recording, wherein the guide elements are circumferentially distributed around the net receiver, wherein the guide elements are tube-shaped, in particular as Fluidauslassleitungen with an inner Fluidfüh- rungshohlraum and at least one fluid outlet, which is arranged at an axial end portion of the relevant fluid outlet, such that fluid guided through the fluid guide cavity can exit the fluid guide cavity through the fluid outlet, or wherein the guide elements are formed like a mandrel or rod, and wherein each guide element is adapted to be placed on it a projectile-like mass element along the outside ßenseite the guide member or placed.

By such a construction of the interceptor, the mass members are not received in a run-like channel but are in an assembled condition, i. before a launching process, as it were slipped over the guide elements or the fluid outlet line. In this state, the mass elements are accordingly also easily accessible, so that the connections to a network need not be arranged within a gas-carrying line. It is further proposed that the interception device comprises a safety net which is connected to a plurality of projectile-like mass elements, the number of mass elements corresponding to the number of guide elements, wherein the interception mesh is received in the net receptacle and each guide element is associated with a projectile-like mass element.

The safety net can preferably be rectangular, in particular square, with each corner of the safety net being connected to a mass element. To connect the interception network with the mass elements fastening means may be provided on the mass elements, which can be coupled with the interception net pelbar. For example, at least one eyelet can be provided on a mass element into which a connecting section coupled to the safety net, for example a cord or a wire or the like, is inserted.

The interception network is added folded in the network recording in a predetermined manner, so that when shooting down the mass elements ensures that the interception net spans in the desired manner during the flight to absorb the flying object to be intercepted and bring it to targeted crash. It is further proposed that the projectile-like mass elements are sleeve-shaped with a closed end and with an open end, such that they cover an end portion of the guide element in the mounted state, in particular cover the respective fluid outlet at a respective fluid outlet. The above-mentioned at least one eyelet can in particular be provided in the region of the open end, for example, on the outer circumference of the sleeve. It is also possible that the eyelet part of a ring member which is attached to the mass element and is movable relative to this, in particular rotatable. This allows the firing of the mass elements, an automatic rotation or alignment of the ring or the eyelet (s) in an optimal position.

At least one sealing element can be arranged on a respective outer side of the guide elements. In this case, in the mounted state of the sleeve-shaped mass element, the sealing element can be arranged between an inner wall of the mass element and an outer wall of the guide element. By means of the at least one sealing element, it is possible to ensure that an overpressure is built up in the interior of the sleeve-like mass element, so that the mass element is moved or accelerated relative to the guide elements or to the fluid outlet line. The sealing element prevents in particular the occurrence of a pressure loss, which would adversely affect the acceleration of the mass element.

The sealing member may be located upstream relative to the fluid outlet of a fluid outlet conduit. It is further proposed that a plurality of sealing elements are arranged on each guide element, which are arranged with respect to a relative direction of movement of an associated mass element or with respect to the flow direction of fluid in the fluid outlet at a preferably regular distance from each other. By providing a plurality of sealing elements, it can be ensured that the seal between the moving mass element and the relevant guide element exists for a sufficient duration in order to avoid pressure losses during acceleration of the mass element as far as possible. The sealing element may for example be designed as an O-ring, which is provided in an associated annular groove on the guide element.

The interceptor may further comprise at least one inflator configured to generate a propellant gas entering a cavity defined by a respective guide member and associated mass member. Such an inflator may in particular also be an airbag inflator known from automobile technology.

It is proposed that each fluid outlet line is associated with a gas generator or that each mass element is associated with a gas generator. This can ensure that in each Fluidauslassleitung sufficient Gas pressure can be generated to pressurize and accelerate the respective mass element. If a gas generator provided on a mass element, this acts as a kind of nozzle drive for the mass element and is moved away from the guide element with the mass element.

Further, the interceptor may include a controller configured to send an electrical signal to the inflator or to all inflators to initiate the production of propellant gas. For this purpose, the intercepting device can comprise at least one electric current source, in particular a battery, which is set up to supply the control device and the gas generator or all gas generators with electric current.

The interceptor may further comprise a holding device adapted to hold the interceptor one-handed or two-handed by an operator.

In order to transfer a pressure resulting from expanding gas as lossless as possible, a liquid-filled section can be provided in each fluid outlet line, which is sealed within the fluid outlet line, in particular by means of an upstream membrane and a downstream membrane, wherein the membranes are preferably formed in that they tear by generating a predetermined pressure. Since the liquid is incompressible, the pressure transfer takes place directly in the relevant section without the gas pressure first having to build up in this line section.

The interceptor may further include a fluid inlet chamber connected downstream to all the guide elements formed as fluid outlet conduits, the fluid inlet chamber being connectable or connected to at least one gas generator. By such a construction, propellant gas can be introduced or generated in the region of the fluid inlet chamber, which is then distributed into the fluid outlet lines. In general, it may be sufficient in this case that only one gas generator is used, as long as it can build up a sufficient pressure for all gas outlet lines.

The interceptor may be coupled or coupled in the region of the fluid inlet chamber with adapter means adapted to connect the interceptor to a gas pressure weapon, the gas pressure weapon being adapted to ignite a propellant charge to prevent fluid ingress. Allow passage chamber and the Fluidauslassleitungen a gas under increased pressure. In this case, the gas pressure gun serves as a gas generator.

In the following, the invention will be described in more detail with reference to the appended figures with reference to non-limiting exemplary embodiments.

Interception device with a holding device.

Fig. 1 1 shows schematically and simplified in a sectional view of an interceptor, which is detachably connected to a holding device. 1 shows in a simplified and schematic perspective view of an interceptor 10. The interceptor 10 is shown in FIGS. 2 and 3 in a respective sectional view, approximately corresponding to the section line II-II of FIG. 1st The following description refers to FIGS. 1 to 3 to explain the structure and operation of the interceptor 10, without in each case explicitly refer to one of the Fig. 1 -3.

The interceptor 10 has a plurality of, in the present example, four guide elements 12. The guide elements 12 are formed here as Fluidauslassleitungen 12a. These are provided or arranged in an outer housing 13 of the interceptor 10. The outer housing 13 has a conical or funnel-like shape. The fluid outlet lines 12a are tube-like and have an internal fluid guide cavity 14. Respective projectile-like mass elements 16 are arranged or placed along the fluid outlet lines 12a. In this case, the mass elements 16 have an inner diameter that essentially corresponds to an outer diameter of the associated fluid outlet lines 12a. The mass elements 16 are formed as unilaterally closed sleeves. In this case, the respective closed ends 18 of the mass elements 16 form a front side or tip of the mass element 16 relative to a main movement direction.

The interceptor 10 has a longitudinal axis LA. In an axially rear region, the interceptor of the present example comprises a coupling portion 20. This coupling section 20, here designed as an internal thread, for example, is in fluid communication with the fluid guide cavities 14 of the fluid outlet lines 12a. The coupling portion 20 can also be referred to as a fluid inlet chamber 22, into which a fluid, in particular a gas is introduced, which is then passed into the fluid guide cavities 14. The fluid outlet conduits 12 a have a respective front portion 24. In each case at least one fluid outlet opening 26 is formed in the sections 24. When a fluid, in particular a gas, flows at high pressure into the fluid outlet lines 12a or the fluid guide cavities 14, it exits again at the fluid outlet openings 26. The fluid flows into a cavity 28 provided in the respective mass elements 16. As a result, the mass elements 16 are moved, in particular moved away, relative to and along the fluid outlet lines 12a, as shown in FIG. In FIG. 3, FR designates the initial direction of flight of the mass elements 16. The direction of flight FR may also be referred to as the conduit axis of the fluid outlet conduits 12a.

In a central or central area, a network receptacle 30 is provided in which a trapping network 32 is accommodated. The interception network 32 is shown purely schematically in the figures with a triangular hatching. This triangular hatching does not say anything about the mesh type and mesh size of the intercepting net 32, but merely serves for the schematic illustration of the interception net 32. The interception net 32 is arranged in a predetermined manner folded in the net pickup 30. The mesh receptacle 30 is at least partially bounded by the fluid outlet conduits 12a. In particular, the mesh receptacle 30 is surrounded or formed in a lower portion of base portions 34 of the fluid outlet conduits 12a. The mass elements 16 have, in the region of a rear end section 36 which is rearward in relation to the direction of flight FR, at least one connecting element 38, in particular a connecting eye, with which the intercepting network 32 can be connected or connected. 2 and 3, a mass element 16 is shown in the center, which has two connection eyes 38. Typically, the interception network 32 by means of cords or wires (not shown) connected to the connection eyelets 38. In this case, the length of the cords or wires is chosen so that extraction of the trapping network 32 from the network receptacle 30 takes place only when the mass elements 16 are completely removed from the Fluidauslassleitungen, in particular the housing 13 of the interceptor 10 have left in the direction of flight FR. The connection eyes 38 are firmly connected to the mass element 16 in the illustrated example. It is also conceivable that such connection eyelets 38 are arranged on a ring 42. Such a ring 42 may for example be rotatably received in a circumferential groove 44 of the mass element 16, so that the ring 42 and thus the connection lugs 38 can align optimally when firing the mass elements 16. Such a configuration is illustrated by way of example on the right in Fig. 2 and 3 mass element 16.

The guide elements 12 and fluid outlet lines 12a are inclined with respect to the longitudinal axis LA. As can be seen in particular from the sectional views of FIGS. 2 and 3, the line axes FR extend inclined to the longitudinal axis LA. As a result, the accelerated mass elements 16 move along their initial direction of flight FR with respect to the longitudinal axis LA away from each other. Due to this direction of movement of the mass elements 16, the interception network 32 is clamped during the flight. This makes it possible that by means of the interception network 32, an unmanned flying object, in particular at a height of about 10 to 50 meters above the ground, intercepted and can be brought to crash crashed. At least one sealing element 46 is arranged between the guide element 12 or the fluid outlet line 12a and the mass element 16. The sealing element 46 serves, in particular, to seal the cavity 28 filling with fluid, so that the mass element 16 can be accelerated relative to the guide element 12 or to the fluid outlet line 12a. In this case, the sealing element 46 is in particular arranged so that the sealing effect is maintained over as long a period as possible, while the fluid pressure in the expanding cavity 28 is increased. In the present example (FIGS. 2 and 3), three sealing rings 46, which are received in corresponding grooves, are provided on each guide element 12 or on each fluid outlet line 12a. It should be noted that not necessarily three sealing rings 46 must be used. It is also possible to use more or less sealing elements. It is conceivable, in particular, that only one sealing element is used, for example, at a position which lies as far forward as possible with respect to the outlet axis FR, which in FIGS. 2 and 3 may approximately correspond to the position of an upper sealing ring 46. The sealing elements 46 are preferably designed so that the desired sealing effect is achieved, without this greatly limiting the relative movement of the mass element 16 to the guide element 12 or to the fluid outlet line 12a with increasing fluid pressure. Also conceivable, for example, is the use of sealing elements which are provided with an adhesion-reducing coating, such as a PTFE coating. It is also conceivable that the sealing elements are made entirely of PTFE, in particular designed as Teflon ring. Of course, other suitable materials and combinations of materials that are not further described herein may be used for the sealing elements 46.

4 and 5, an embodiment is shown in which the coupling portion 20, which may also form the fluid inlet chamber 22, may be mounted by means of an adapter 46 on a conventional firearm such as tear gas ejector, flare gun or the like. The adapter 46 is screwed into the coupling section 20. In this case, the coupling portion 20 has an internal thread 48 and the adapter has a corresponding external thread 50. The adapter 46, an attachment portion 52 is provided which can be coupled with a barrel of a firearm, not shown here. As 5, the coupling portion 20, together with the adapter 46, forms the fluid or gas inlet chamber 22 which is in fluid communication with the fluid outlet conduits 12. When a propellant charge is ignited by the firing gun, the gas expands in the fluid outlet chamber 22 and the fluid outlet conduits 12a, in particular the fluid guide cavities 14, exits through the fluid outlet openings 26 so that the mass elements 16 are moved and fired by the gas pressure.

FIG. 6 shows in simplified and schematic form an example in which gas generators 60 are used in each case to generate a desired fluid pressure in the fluid outlet lines 12a. Each fluid outlet line 12a is associated with a gas generator 60. The gas generators are connected to a control device 62 (in particular a microcontroller), which is set up to transmit an ignition signal to the gas generators 60, so that the gas generators are ignited substantially simultaneously (synchronously). This ensures that the fluid pressure in all Fluidauslassleitungen 12a increases simultaneously and the mass elements 16 can be launched substantially synchronously. By using gas generators 60 associated with the respective fluid outlet conduits 12a, a fluid inlet chamber 22 (Figure 2) is no longer required. This space may be used, for example, for housing the control unit 62, as illustrated in FIG. 6. It goes without saying that in the case of an intercepting device with gas generators 60, a power supply is also provided for the control unit 62 and the ignition of the gas generators 60, even if this is not shown here. An external power connection, for example in the form of a portable battery or the like, or a battery integrated in the interception device (not shown) may be considered as a power supply.

FIG. 7 shows another arrangement of several gas generators 60 in the region of the fluid inlet chamber 22. The gas generators 60 are likewise connected to a control device 62. If the gas generators 60 are ignited substantially synchronously, the resulting resulting fluid or gas pressure is initially distributed in the fluid inlet chamber 22. In this way, a pressure difference possibly caused by the individual gas generators can be compensated so that substantially the same fluid is present in all the fluid outlet lines 12a - Is applied or gas pressure for moving or firing of the mass elements 16th

8 shows a further embodiment in which a respective gas generator 60 in a front region of the fluid outlet line 12a, in particular very close to the fluid outlet opening 26 is arranged. Further, 16 gas generators 60 a are provided on each mass element, which are moved together with the mass elements 16. Since the gas generators 60a must also be connected to the control device 62, a predetermined breaking point 61a must be provided along this connection 61 so that the connection can be separated after the ignition of the gas generators 60a and the moving away of the mass elements 16. The connection 61 shown here and the indicated predetermined breaking point 61 a (inclined double line) are shown here purely schematically. In particular, the position of the predetermined breaking point 61 a along the connection 61 is essentially freely selectable. The predetermined breaking point 61 a may also be formed by a kind of connector, wherein the connector is released upon moving away of the mass element 16. It is also conceivable that the predetermined breaking point is formed only by two abutting, in particular electrically conductive contact surfaces, of which one contact surface on the mass element 16 and the other contact surface on the guide element 12 and the fluid outlet 12a is provided. In the arrangement of gas generators 60, 60a shown in FIG. 8, in particular in the region of the cavity 28, the fluid or gas pressure can be generated directly where it is also needed to accelerate the mass elements 16. In this way, a pressure loss through longer lines or through larger volumes to be filled, such as fluid inlet chamber, entire Fluidauslassleitungen be counteracted.

Fig. 9 shows an embodiment in which the guide elements 12 are formed as a pin-like or rod-like elements 12b. In contrast to the Fluidauslass- lines 12 a, the thorn-like or rod-like elements 12 b have no gas guide channel 14. The spike-like or rod-like elements 12b can have a solid profile in a cross section orthogonal to the firing direction FR, as indicated in FIG. 9 in the case of the left-hand element 12b. In order to improve the stability of the mandrel-like or rod-like elements 12b, they may also be tubular in cross-section, as illustrated in the right-hand element 12b of FIG. 9. The guide elements 12b shown in FIG. 9 are shown with an outer contour that is substantially similar to the fluid outlet lines 12a. It should be noted, however, that the spike-like or rod-like elements 12b may be designed differently, in particular at their free end facing the cavity 28. It is conceivable, for example, that a surface facing the gas generator 60a is convex, as indicated by a dashed line 66 on the left in FIG. As already indicated above for the embodiment according to FIG. 8, the connection 61 likewise shown in FIG. 9 and the indicated predetermined breaking point 61a (inclined double line) are drawn purely schematically. In particular, the position of the predetermined breaking point 61a along the connection 61 is essentially freely selectable. The predetermined breaking point 61a may also be formed by a type of plug connection, the plug connection being released when the mass element 16 is moved away. Further, it is conceivable that the predetermined breaking point is formed only by two adjoining, in particular electrically conductive contact surfaces, of which one contact surface on the mass element 16 and the other contact surface on the guide element 12 or the mandrel-like or rod-like element 12b is provided.

9, the gas generators 60a associated with the mass elements 16 serve as a kind of drive, in particular a type of jet drive according to the recoil principle, for the respective mass element 16. In this way, if necessary, too the range of the mass elements 16 and of the intercepted intercepting network 32 can be improved if, for example, a propulsion force can still be generated by the gas generator 60a for the first few meters after the launch of the mass elements by the guide elements 12.

In Figs. 6-9, the same reference numerals as in Figs. 2 and 3 are shown to indicate like parts without being described again. In that regard, reference is made for such multiply used reference numerals to the above description of Figures 1 -3.

FIG. 10 illustrates a configuration according to FIG. 6 with a handling portion 70 connected to the interceptor 10. The handling portion 70 is shown here greatly simplified as a handle. The handling portion 70 may also be in the form of a gun handle, such as a gun, or in the form of a neck, such as a rifle. In the area of the handling section, an on / off switch I / O can be provided. Furthermore, a push button or a trigger (trigger) S known by weapons can be provided, by the actuation of which the ignition of the gas generators 60 can be effected by means of the control device 62. The configuration with handling section 70 illustrated in FIG. 10 can also be combined with the embodiments of the interception device according to FIGS. 7 to 9. In Fig. 1 1, a further embodiment is further shown, in which a control unit 62 is integrated in the handling section 70. The intercepting device 10 can then be made interchangeable, wherein the interceptor 10 and the handling portion 70 are detachably connected or connectable in a suitable manner. It is conceivable, for example, a kind of connector or latching or rotary connection, such as in the manner of a bayonet lock. It is provided that in the connected state, an electrical connection is made between the gas generators 60 and the control unit 62. This can be done for example by means of corresponding contact points 72, in which a conductive contact is made or is when the interceptor 10 with the handling portion 70th connected is. In such a configuration, the interceptor 10 may be embodied as a single use module that may be removed after use from the handling section 70 and replaced with a new interceptor 10.

It should also be noted that it may be thought that larger cavities to be filled with fluid, particularly gas at high pressure, may at least partially be filled with an incompressible fluid, such as a liquid such as water or the like, before pressurized gas is introduced. In this case, a desired volume of liquid could be delimited and sealed by membranes. When a certain gas pressure is built up, such as by igniting a propellant in a conventional weapon (flare gun, tear gas ejector) or by igniting a gas generator, the membrane ruptures and the volume of liquid is displaced by the pressurized gas. The mass elements are then initially moved, for example, by the displaced liquid and subsequently by the pressurized gas. By such a measure larger unfilled cavities can be prevented so that an initially generated gas pressure can be used as efficiently as possible in order to accelerate the mass elements and shoot down the safety net. A liquid volume could, for example, be provided in the gas inlet chamber 22 of the embodiments according to FIG. 2 or FIG. 7.
