Description

The invention relates to a drone repulsion device for infant donkey data.Affordable remote controlled aircraft of relatively low mass, for example below 25 kg, can be readily purchased and controlled by hobby pilots. Due to unanswered behavior, such hobby pilots occasionally steer their unmanned aircraft into safety-critical areas such as in the vicinity of runways of an airport, atomic power stations, rescue operations at which helicopter landing is to be expected, and others. It is therefore desirable to be able to repel a flying unmanned aerial vehicle into such zones. In addition to civilian applications of smaller unmanned aerial vehicles, applications of remotely controlled aerial vehicles with a departure mass of less than 25 kg are increasingly to be observed in the military sector. The remote-controlled aircraft often also have a mass of less than 10 kg or even less than 5 kg. It is precisely such small drones that regular air repulsion, which is designed for aircraft with a significantly greater mass and which is located at higher flying spots, cannot be controlled. In the military field as well, it is therefore desirable to have an effective drone repulsion available.One approach frequently used in the prior art is to use a trapping network which is shot or cast, in particular, on the opposing drone to be trapped in the sense of the opposing unmanned aerial vehicle, remotely or autonomously flying, so that the opposing drone becomes entangled therein and crashes.DE 10 2019 108 591 A1 relates to a trapping net for a trapping device, in particular for trapping unmanned flying objects, having a trapping region which has a plurality of net meshes formed by interconnected net threads or net strands, a net enclosure which surrounds the trapping region and to which the net meshes are connected, at least two mass elements which are connected to the net enclosure or are integrated in the net enclosure, wherein the trapping net is configured to be fired by a trapping device, wherein the trapping net is spanned in flight under the action of the accelerated mass elements, wherein the trapping net comprises at least one absorption device which is configured to be triggered upon contact of the trapping region of the trapping net with an object to be trapped, absorbing the forces acting from the mass elements on the collecting region at least partially.DE 10 2016 111 563 A1 further relates to a cap module for a firearm, in particular a gas-pressure firearm, having a gas inlet chamber, a plurality of barrel-like gas outlets which are in fluid communication with the gas inlet chamber, wherein the gas outlets extend at an inclination with respect to a longitudinal axis of the cap module, are arranged distributed in the circumferential direction around the longitudinal axis, and have a respective gas outlet orifice, a network receiving chamber which is separate from the gas inlet chamber and the gas outlets, wherein the gas outlets are arranged distributed in the circumferential direction around the network receiving chamber, and wherein the network receiving chamber has a network outlet orifice, a intercepting network which is connected to a plurality of projectiles, wherein the number of projectiles corresponds to the number of gas outlets, wherein the intercepting network is received in the network receiving chamber and a projectile is inserted in each gas outlet, wherein the projectiles are designed such that they are driven through the respective gas outlet substantially synchronously by a gas pressure built up in the gas inlet chamber and emerge at the respective mouth, such that the intercepting net is pulled out of the net receiving chamber and deployed during flight.In addition to the above mentioned intercepting nets, it is also known in the prior art to apply a plurality of free filaments or light bands which are intended to be intercepted in particular in one or more propellers of the opposing drone in order to impede or completely override their thrust for generating buoyancy and maneuverability. In contrast to typical nets, the aerodynamic properties of which are so low compared to their mass that they quickly change to a free fall and fall to the ground, such threads and straps have not negligible aerodynamic properties and tend to have a relatively slow free sinking speed as long as they are not connected to another mass element.EP 3109586 A1 relates to a projectile for intercepting a small drone for this purpose, comprising a propellant charge sleeve having a propellant charge and a propellant charge initiator; and a projectile connected to the propellant charge sleeve, in which projectile an activation means, an ejection means and an effector comprising a plurality of threads are accommodated, wherein the activation means is suitable for activating the ejection means in a time-delayed manner after the propellant charge has been ignited, such that the effector is ejected from the projectile in the direction of the small drone.US 11022408 B2 further relates to a system for firing a target drone having propellers arranged along a circumference, comprising a capture drone having a flexible, elongate capture gun and an on-board camera; an on-board processor for receiving sensed wind conditions and determining a shot distance between intercept and target drone at a given shot angle, and wherein the on-board processor is configured to track the target drone from images generated by the on-board camera, at least once when certain wind conditions are present, to guide the intercept drone to a shot position a certain distance from the target drone, and to trigger the gun to fire at a certain shot angle once said shot position is reached, thereby utilizing the flexible elongate intercept means for firing target drones.WO 2021162634 A1 also relates to a drone intercepting system and a belt launcher mountable on an intercepting drone. In this system, the strings are packaged in a string pusher, which is in turn contained in a cartridge case. In use, the bands are ejected from the band pusher and an associated launch tube and generate a band cloud in the trajectory of a propeller driven target drone. The contoured impeller surface at the face of the band slide interacts with the drive gases and thus generates rotation. When the target drone enters the belt cloud, its propellers become caught on some of the belts floating in the cloud. This leads to a malfunction of the propellers and a non-destructive fall of the target drone.US 11255643 B2 also relates to an air burst projectile and a system for ejecting the air burst projectile for repelling an unmanned aircraft. Each air burst projectile comprises one or more spinners; each spinner consists of a sleeve or tube, a plurality of radial separator plates extending from the sleeve / tube, and an annular backing plate connected to the sleeve. Adjacent separator plates thus form a compartment. In each compartment there is one or more rolled up bands. When the air burst projectile is placed in the trajectory of a target UAV, the spinners are ejected and the tapes are dispersed in the trajectory, creating a tape cloud. One or more of the bands may become caught in the propellers of the UAV and cause the same to crash or serve as a warning shot or boundary marking.In modern war scenarios, it is to be expected that an infantry oildate is attacked by a small, possibly fast, unmanned aerial vehicle with combat bodies. Such a small drone or small drone is typically remotely controlled, for example by a wireless radio connection or with the aid of a pulled-on glass fiber cable, but can also be guided fully automatically. An infantry oildate is often surprised by such an attack, since no or only poor automatic detection systems are available which could recognize such small drones sufficiently early so that coverage could be sought from the infantry oil data.It is an object of the invention to provide an improved drone repulsion for infant donkey data.The invention results from the features of the independent claims. Advantageous refinements and refinements are the subject matter of the dependent claims.A first aspect of the invention relates to a drone repulsion device for infant donkey data, comprising a receiving device for receiving a plurality of threads and a firing device which is designed to exert a direct or indirect force impact on the plurality of threads in response to a trigger signal, such that the plurality of threads are shot from the device and form a cloud of threads to the drone repulsion in the vicinity in front of the device.The receiving device serves for receiving a plurality of threads or other means acting identically or substantially identically or similarly compared to threads. The term "threads" is also understood to mean belts, wherein a thread can be formed from thinner individual threads. In an initial state, the threads or bands are accommodated in a space-saving manner in an accommodation unit, for example wound up, rolled up, folded or accommodated in another manner saving volume.The result of the actuation of the launcher for discharging the threads is a maximum longitudinal extent of a respective thread or a respective belt in order to span in its entirety a maximum surface area or a maximum volume in the air, so that an opposing drone, also referred to as unmanned aircraft, is most likely to be caught therein and brought to fall or at least changed in its course due to impairment of controllability.The launcher itself preferably uses expanding gas, whether by expansion of gas from a pressurized reservoir or by pyrotechnics, which upon ignition converts a solid to expanding gas. A Venturi nozzle can also be used here to increase the speed during the expansion of the gas stream. In addition to a propellant charge, such an acceleration of the filaments can also be effected by electromagnetic action, by spring pressure or by others.The device can have one or preferably a plurality of active agent sleeves. In the case of a plurality of active agent sleeves, their triggering can be effected individually manually, manually in a sequence-triggering manner, manually and in a position-triggering manner. Upon triggering, individual triggering characteristics can preferably be programmed for the active agent sleeves.With the cloud of threads, which is formed by itself by aerodynamic effects on the threads when the threads are released from the receiving unit, a planar or three-dimensional structure of threads is produced. If such a planar or spatial region is spanned by straps or threads, and this is preferably in the direction of the opposing drone, that is to say the unmanned aerial vehicle to be captured opposingly, there is a considerable probability during the entry for the unmanned aerial vehicle of getting entangled in coming off the planned course or even falling off.Preferably, corresponding fibers or bands are selected with properties such that they have a certain minimum tensile strength, but nevertheless have the highest possible ratio of aerodynamic forces in relation to inertial forces, in order to float as long as possible in the air and have the lowest possible sinking speed towards the earth. In particular, threads can be formed from fibers, in particular from ultra-high molecular weight polyethylene, aramid, polyamide, carbon fiber, polyester, polyetheretherketones or other plastics. The belts can be manufactured as woven fabrics of single fibers or of continuous material. A thread itself can again consist of individual cases, in particular parallel individual threads or knitted thread structures.The threads or the bands can be laid loosely in the receiving unit, wound up on spools, and wound in such a way that they produce a bellows that can be unwound from the inside, wound up individually, wound up in multiple threads, and in a further embodiment can be designed to be electrically conductive.The device thus forms a hand-operated launcher suitable for drone repulsion, particularly in situations where a hostile small drone moves towards an infantryol data and the infantryoldate can use the device as the last distributing means.According to an advantageous embodiment, the apparatus has a driving mirror which is arranged between the launcher and the plurality of threads.According to a further advantageous embodiment, at least a subset of the plurality of threads are connected to one another at least in pairs by cross-connections.According to a further advantageous embodiment, the firing device has a pyrotechnic propellant charge.According to a further advantageous embodiment, the threads are plastic threads.According to a further advantageous embodiment, the device has a tension element which is connected to a triggering device, wherein the triggering device is designed to generate the triggering signal.According to a further advantageous embodiment, the device comprises a mechanical coupling element for attaching the device to the infantryol data, wherein the tension element is configured to be connected to a piece of clothing or an item of equipment of the infantryol data, such that the tension element activates the triggering device when the device is removed from the infantryol data and the tension element experiences a tension relative to the piece of clothing or item of equipment of the infantryol data.According to a further advantageous embodiment, the tension element is designed for manual operation.According to a further advantageous embodiment, the launcher is configured to transport the pick-up device out of the apparatus, wherein the pick-up device is configured to transport the plurality of threads out of the pick-up device after leaving the pick-up device from the apparatus to form the cloud of threads.According to a further advantageous embodiment, the apparatus is designed to determine a distance between the receiving device and the remaining apparatus at which the plurality of threads are conveyed out of the receiving device.According to a further advantageous embodiment, the device is designed to determine the distance depending on a distance to a hostile drone.According to a further advantageous embodiment, the device has an assembly interface for attachment to a terrestrial vehicle or an aircraft.According to a further advantageous embodiment, the device is designed for manual handling.Further advantages, features and details are evident from the following description, in which--possibly with reference to the drawing--at least one exemplary embodiment is described in detail.The following are shown: FIG. 1 : shows a drone repulsion device for handling by infantryol data according to an embodiment of the invention. FIG. 2 : shows an infantryole data with a command vest with a receptacle for receiving the device according to FIG. 1 according to an exemplary embodiment of the invention.The representations in the figures are schematic and not to scale.FIG. 1 shows an example drone repulsion device for handling by infantryol data. The device has a firing device 3 and a receiving device 1 arranged above it. FIG. 1 shows the device immediately after termination, i.e. after triggering, by a triggering signal on the firing device 3. The receiving device 1 receives a plurality of threads 2 in the initial circumstance, which are fired forward out of the device when the firing device 3 is triggered, wherein the sabot is co-spun. For the sake of simplicity, only a single one of the threads 2 is designated as such in FIG. 1. A tension element 4 serves to trigger the trigger signal manually. When pulling on the tension element 4, the trigger signal is thus generated and the firing device 3 is triggered to ignite the pyrotechnic charge. As a result, even in the absence of a shotgun or other suitable repulsion measures, the infantry oildate can hold it at a short distance, i.e. in the vicinity of in particular zero to eight meters, on a hostilely flying drone and deflect the course thereof by the cloud of threads 2 or bring it to a fall.FIG. 2 schematically shows an infantryol data with command vest. At the command jacket, a receiving device d for receiving the device is arranged as shown under FIG. 1. The traction element 4 shown in FIG. 1 and mentioned in the description thereof is connected to this receptacle d, so that when the device is torn off from the receptacle d, a tensile force is exerted on the traction element 4, as a result of which the device is activated and, with a predetermined time delay, the triggering signal is automatically generated by the device in order to trigger the firing device 3 for firing the propellant charge arranged therein.Although the invention has been illustrated and explained in more detail by preferred exemplary embodiments, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by the person skilled in the art without departing from the scope of protection of the invention. It is therefore clear that a large number of possible variations exist.
