Definitions
- the present invention relates to a magnetic Kompensa ⁇ tion device for a drone for mine release, wherein the compensation device comprises a flux guiding element and a receiving space for the drone. Furthermore, the invention relates to a method for changing the temporary compensation of the magnetic field of a drone by means of such a device.
- unmanned drones which are equipped to trigger magnetic ⁇ mines with magnetic coils or with permanent magnets. These coils or permanent magnets create strong magnetic fields that can detonate the sea mines.
- the drones are designed so that they are not damaged by the detonation at the typical distance for the triggering.
- Such drones can have their own propulsion system, for example, the German Navy has remote-controlled boats of the "seal" type, which are equipped with a diesel engine.
- the magnetic system for triggering the mines is integrated in the fuselage of the remotely controlled boats.
- underwater drones for mine clearance are also known, which either have their own propulsion or can be towed by other (sub) vessels.
- a disadvantage of the known mine clearance drones with magnetic coils is that they are very heavy and usually also relatively large due to the large weight of the magnetic coils required for the strong magnetic fields.
- the transport of such drones to different locations is relatively expensive, especially a transport by plane is considerably complicated by the high Ge ⁇ weight.
- a permanent energy supply is required, which also contributes to the weight.
- the drive motor also contributes to the high weight and volume.
- an energy supply for example in the form of fuel for a diesel engine or in the form of electrically stored energy for an electric motor.
- demining drones with permanent magnets instead of magnetic coils may be comparatively less powerful
- the object of the invention is therefore to provide a magnetic Kompen ⁇ sationsvorraum for a drone for mine release available, with the magnetic field of such a drone for the transport at least partially compensated who ⁇ can.
- a compensation device should be designed with the lowest possible weight so as not to contribute too much to the transport weight. You should continue to be as robust and easy to use.
- Another object is to provide a method for changing the temporary compensation of the magnetic field of a drone with such a device. In other words, either those temporary Kompensa ⁇ tion is to be effected by this process or it should be set aside an existing temporary compensation.
- the compensation device is designed for magnetic ⁇ -Nazi compensation for a drone to the mine triggering. It comprises at least one flux guiding element of a soft magnetic material having the structure of an open or closed ring. It also comprises a receiving space for the mine clearance drone, in which it can be kept ⁇ ge, and additionally at least one electric coil means which is magnetically coupled to the flux-conducting element, that with the Spulenein ⁇ direction a predetermined magnetic flux in the flux-conducting Element can be coupled.
- the flux- guiding element and the receiving space are so arranged angeord ⁇ net that a caused by the drone magnetic field in the flux-conducting element can close annular.
- Under the said recording space for the drone here is not necessarily a closed space to be understood, but in general a place in the area of the compensation device, where the drone can be kept.
- the drone can be held in this receiving space so that it can be transported together with the compensation device.
- the first named alternative of an "open ring” is to be understood in general to mean a ring-like shape which has a gap or an open leg, etc. Under such a form, in particular, a U-shape should also be included.
- a magnetic field in the flux guiding element can close in such a ring shape that the drone's magnetic field is shielded from the outside environment. It can either be introduced into the recording room drone part of the magnetic ring closure within the flux guiding element (variant "open ring”) or else the flow ⁇ leading element surrounds the drone to be introduced ringför mig (variant "closed ring”).
- the present within the compensation device elec- tric coil means causes the magnetic field of the drone in the compensation device can not only close, but that it can be actively compensated
- a magnetic flux can be coupled into the flux-conducting element wel ⁇ cher which is opposed there by the drone a coupled magnetic flux.
- Such magnetic Kompensa ⁇ tion need not be complete, but it may be at least a part of a coupled by the drone may ⁇ netic flux are kom ⁇ compensated within the flux guiding element advantageous.
- the drone's magnetic field is effectively shielded from the outside by the flux-bearing element, allowing the drone to be transported by the much lower external magnetic field.
- the drone's magnetic field is effectively shielded from the outside by the flux-bearing element, allowing the drone to be transported by the much lower external magnetic field.
- by such a shield even a transport with an aircraft can be made possible.
- the inventive method is used to change the tempo ⁇ rary compensation of the magnetic field of a drone for mine release by means of a compensating device according to the invention.
- the method comprises the following steps:
- the compensation device comprises at least one sensor unit, with ⁇ tels of which a physical property can be measured, which depends on the relative position of flux-conducting element and drone.
- the device may then comprise at least one control device by means of which a fed-in electrical coil current in dependence on the measured size of the physi ⁇ 's property can be controlled.
- the introduction or removal of the drone in this advantageous embodiment can be carried out with variable supply of a compensation magnetic field by the coil device.
- the respectively at a given date fed-in current can be set to be that the forces acting between Before ⁇ direction and drone magnetic forces is reduced or even minimized. It is principally unerheb ⁇ Lich over which physical property, the relative Po ⁇ sition is tracked between drone and device. Lent essential is that by measuring the physical property is present in at least a part of information on this relative position, and thus the current in the coil means may be adjusted such that a Relativbewe ⁇ supply is facilitated between drone and apparatus.
- the flux- guiding element may have the structure of a closed ring which surrounds the receiving space for the drone.
- An advantage of this embodiment can be, for example, that the device can be made approximately symmetrical and can be adapted as well to the shape of a symmetrical drone.
- the flow ⁇ leading element having a hollow cylindrical basic shape with circular ⁇ shaped cross-section and thus enclose a circular cylindrical drone look relatively accurate.
- the flux guiding ele ment ⁇ may have a comparatively low weight, under certain circumstances, since it can be formed with relatively less material when it symmet- the drone encloses driven and narrow.
- the flux guiding element may also have the structure of an open ring, wherein the receiving space is arranged in the open region of the ring structure.
- the receiving space can thus be arranged in the region of the open leg of an approximately U-shaped structure.
- the flux-conducting element can be particularly material-saving and thus very easily performed, since the drone does not have to be surrounded on all sides of the soft magnetic material.
- Another advantage of this embodiment is that the electric coil for coupling the compensa- tion field can be disposed at a location remote from the drone Be ⁇ rich of the ring.
- a flux guiding element in the region adjoining the receiving space area the at least at least one collector, but particularly preferably two collectors aufwei ⁇ sen.
- a collector is meant a structure which facilitates the collection and bundling of the drone-originated magnetic flux in the flux-conducting element.
- collectors may be designed in the manner of magnetic pole shoes. So you can in the drone area a particularly high contact surface (or magnetic Kirwir ⁇ kungs Construction, if there is no direct mechanical support) respectively.
- Such "interaction surface” can be substantially larger than the cross section of the flux guiding element in the other lying on the drone further away areas insbeson ⁇ wider.
- An important advantage of this execution is approximate shape with at least one collector that a size ⁇ rer part of of the drone outgoing magnetic flux is concentrated in the flux guiding element and thus leakage ⁇ flows are reduced in the area of the compensation device.
- the configuration of the flux guiding element with at least one collector is particularly preferred especially in combination ⁇ hang with the embodiments with an open ring.
- the sensor unit for measuring the position-dependent physical property can in principle be designed differently.
- the sensor unit generally comprise a distance sensor.
- it may be a distance sensor based on an optical distance measurement.
- an infrared-based distance measurement should also be included under this term.
- the sensor unit may comprise a position sensor-in particular an optical position sensor-which, in addition to the pure distance of the two relevant objects, may for example also determine their rotational orientation zueinan ⁇ .
- the sensor unit can hold a magnetic sensor.
- the magnetic sensor can be designed to measure the magnetic flux density and / or the change in the magnetic flux density within the flux-conducting element or between the flux-guiding element and the drone.
- the magnetic sensor can also be designed for measuring a stray flux in the vicinity of the compensation device.
- the magnetic sensor may be a Hall sensor.
- the sensor unit may comprise a force sensor. Such a force sensor can be designed, for example, for measuring the amplitude and / or direction of a force acting between the drone and the flux-guiding element.
- the sensor unit can also comprise various possible combinations of the sensor types described above.
- the apparatus advantageously comprises one or more spacing ⁇ holder between the flux-guiding element and the receiving space, which are preferably out of non-magnetic material forms ⁇ .
- Such spacers can advantageously serve to enable a more accurate positioning between the drone and flux guiding element and / or to keep the drone after positioning in its desired position.
- the non-magnetic design of the spacers is particularly preferred because otherwise the magnetic forces between the drone and the device could become so great that the
- the width of the gap between the drone to be arranged in the receiving space and the soft magnetic parts of the device may be in a range between 0.1 cm and 10 cm. In this area of the gap widths, a good magnetic flux guidance and nevertheless a good positioning of the drone can be achieved at the same time (at least when a compensation field is fed in via the coil device).
- the soft magnetic material of the flux guiding member can advantageously have a relative magnetic permeability from we ⁇ ilias 300, especially at least 1000 or even at least 3000th
- the soft magnetic material may comprise iron, cobalt and / or nickel as well as alloys with said metals.
- the main constituent of one of the metals mentioned may be.
- Soft magnetic materials are particularly suitable for effectively collecting and ringing a high magnetic flux of the drone with the flux guiding element, with a comparatively small magnetic field in the external environment.
- the flux guiding element may be composed of several separate individual elements. Such a multi-piece design can greatly facilitate the introduction of the drone in the compensation device or their removal.
- the flux guiding element may comprise a joint or a hinge (or several of them). This may be advantageous, especially in connection with an embodiment as an open ring, since then with the hinge or hinge, the gap in the ring can be temporarily increased further to accommodate the drone therein. After closing the hinge or hinge, the flux guiding element can relatively tightly surround the drone.
- the compensation device and / or the method for compensation may advantageously be designed so that even without supply of a compensation field by the coils ⁇ device of the present outside the device magnetically schematic flow a value of 500 ⁇ (in particular even 100 ⁇ ) does not exceed. This is to be achieved in particular for a drone whose uncompensated magnetic field in a region outside the drone has a magnetic flux of 100 mT or more.
- the order of the above steps is not necessarily set to the be passed ⁇ order.
- the sequence can also be reversed and / or the steps can be carried out simultaneously and / or several such steps can be carried out alternately one after the other.
- the method may additionally include the fol ⁇ constricting steps of:
- Regulation of the fed into the coil means current as a function of the measured value of the sensor unit during the insertion or removal.
- the drone alternatively or additionally has a magnetic device with at least one electromagnetic coil for generating a magnetic field.
- This can in particular be a superconducting coil, which, for example, in a quasi-permanent short-circuit current mode ("quasi-continuous"). persistent-mode) is operated. Even with such coils, it may be advantageous not to interrupt the flow of current for a transport and instead to compensate for the magnetic field with the device described.
- the electric coil device can be operated so that the magnetic field of the drone in the flux guiding element is at least partially compensated.
- the coil device can be operated so that a coupling is ⁇ ter through them in the flux guiding element, a magnetic flux-coupled magnetic flux is opposed to by the drone there.
- a compensation need not be complete, but it suffices for this embodiment, a proportionate compensation, so the presence of flux contributions with different signs.
- the coil device is operated so that the magnetic flux of the drone in the flow ⁇ leading element is compensated for at least 10%. In a particularly preferred embodiment, the magnetic flux can even be compensated to at least 50%.
- the method may preferably additionally include the step of jointly transporting the magnetic compensation device and the drone.
- the transport is a transport by an aircraft.
- an electric current is also fed into the coil device during transport in order to at least partially compensate the magnetic field of the drone in the flux-guiding element.
- this variant therefore, also lies during Trans ⁇ ports an additional compensation of the magnetic field of Droh ⁇ ne before, which goes beyond the pure ring closure of the magnetic flux in the flux conducting element. That's how it works magnetic residual field in the environment of the drone be ⁇ teten compensation device can be reduced particularly effective.
- the Spulenein ⁇ direction is de-energized.
- This is advantageous because then during transport no additional Einspeisevor ⁇ direction is required for the current of the coil means and their weight can be saved accordingly.
- Wei ⁇ terhin could lead to additional disturbances which are avoided in this variant also on a flight transporting operation of the electric coil device.
- the coil device is only supplied with current in order to compensate for its magnetic field during the introduction and / or removal of the drone.
- the magnetic field of the drone is closed by the annular flow guide in the flux guiding element and thereby allow any large magnetic field components in the external environment of the compensating device.
- the magnetic flux in the environment outside the compensation device may also be advantageously limited to ⁇ 100 ⁇ in this variant.
- the measured physical egg ⁇ genschaft can advantageously the distance and / or the spatial direction from ⁇ between flow leading element and be drone.
- the measured physical property may be a magnetic flux density and / or a modifier ⁇ alteration of the magnetic flux density within the flux guiding element and / or in the region between the drone and flow leading element and / or in the environment of the drone.
- the physical property measured can be the amplitude and / or direction of a force Zvi ⁇ rule flow leading element and drone.

- FIG. 4 shows a compensation device according to a third embodiment with introduced drone schemati ⁇ rule longitudinal section.
- a single UAV 1 is shown to the mine triggering in schematic longitudinal section, as they can be used in the réellefol ⁇ constricting embodiments of the compensation device.
- Shown is an elongated shaped drone 1 with an outer housing 2, which is designed for locomotion under water. She points in her back (in the
- the drone can also be towed by a rope, for example.
- a generator could be provided instead, for example, with which also optionally present magnetic coils can be supplied with electrical energy.
- the solenoid device 11 comprises at the UAV of Figure 1, three separate permanent magnets 13 whose spatial Reg ⁇ processing is different, so that magnetic fields having different orientations are generated. In principle, it is sufficient, however, if only one of these permanent magnets 13 is present to generate a sufficiently strong for mine triggering Mag ⁇ netfeld outside the drone.
- the three different union under ⁇ permanent magnets 13 are here thus only for ⁇ way for the different orientations to understand. However, in principle, as shown here, there may be a combination of a plurality of such magnets. Or the permanent magnets can also be partially or completely replaced by Mag ⁇ net coils.
- FIG. 2 shows a compensation device 21 according to a first embodiment of the invention in the schematic
- This compensation device 21 has a receiving space 25 into which a drone 1 with an internal permanent magnet 13 is already inserted. This permanent magnets 13 here is oriented so that the strongest magnetic flux is aligned with the longitudinal axis of the drone in ra ⁇ dialer direction.
- the compensation device 21 has a flux-conducting element 23, which is designed here as a U-shaped iron yoke.
- the receiving space 25 for the drone is here formed by the open leg of the U-shape.
- the conditioned by the drone magnetic flux 37 may as illustrated include within the flux guiding ele ments ⁇ 23rd
- the drone itself thus closes the offe ⁇ nen part of the ring of the flux guiding element.
- the compensation device 21 has a coil device 31, which is arranged around a leg of the flux guiding element 23 around.
- a current source 35 By means of a current source 35, an electrical current can be fed into this coil device 31 via its own circuit 33, so that a further magnetic field is generated by the coil device 31.
- an additional magnetic flux 39 is coupled into the flux-conducting element 23.
- This magneti ⁇ specific flow 39 is opposite to that caused by the drone magnetic flux 37, as indicated by the direction of the arrows.
- the caused by the coil means 31 magnetic flux is lower than that caused by the drone magnetic flux 39, which is to be indicated by the ge ⁇ dashed line in this example. It is therefore only a proportionate compensation of the running within the element 23 magnetic flux. However, the strength of this proportionate compensation can be varied.
- the compensation device 21 is equipped with a sensor unit 41, which has one or more sensors 43.
- a sensor unit 41 which has one or more sensors 43.
- two such sensors are shown by way of example. These sensors may be different types of sensors, as described above in general terms.
- here may be a combination of an optical sensor and a force sensor, wherein the force sensor measures the force acting between the drone and compensation device ⁇ magnetic force.
- the sensor device 41 is (irrespective of the exact configuration of the sensor or the sensors) connected to a control device 45, by means of which the current fed into the coil device 31 by the current source 35 can be varied. In this way, therefore, the magnetic flux component 39 will vari ⁇ ated, so the degree of magnetic compensation.
- two spacers are introduced 27 which are formed of non-magnetic material in the shown example between the UAV 1 and the flux-guiding element.
- a magnetically non-effective gap 47 is formed between the drone and the flux guiding element, which may for example have a width of 1 cm.
- the flux-guiding element 23 is here equipped with two collectors 29 which extend with a widened support surface (the support here indirectly via the spacers 27 is realized) to the
- FIG. 3 shows a compensation device 21 according to a second exemplary embodiment of the invention in a schematic longitudinal section, likewise with an inserted drone 1 in the receiving space provided for it.
- the compensation device 21 of this example has a flux guiding element 23, which forms a closed ring here and is designed in the manner of a circular cylinder. Similar to FIG. 1, a schematic half section is shown here, so that only the rear half of the cylindrical flux guiding element 23 is shown. Overall, however, the flow-guiding element 23 surrounds the drone 1 in an annular manner.
- the element 23 surrounds the drone 1 in a region in the interior of which a permanent magnet 13 is in turn arranged so that its magnetic axis is oriented in the radial direction.
- the axis is here meant that connects the magneti ⁇ 's north pole N and the magnetic south pole S with each other.
- the main direction of the strongest magnetic flux outside of the permanent magnet 13 is therefore essentially oriented upwards and downwards, as indicated by the field line 37 by way of example.
- This caused by the drone magnetic flux 37 can close within the two halves of the flux guiding element 23, as shown schematically here for the rear half. Thus, even in this arrangement, leakage flux leakage into the external environment of the compensation device 21 is largely avoided.
- the magnetic flux can also close in the front half of the circular cylindrical element 23, which is not shown here.
- an electrical coil device 31 is also guided around a partial region of the flux-conducting element.
- Only such a coil device is shown here. This is sufficient to effect a proportionate magnetic field compensation at least in the rear half.
- one or more other such Spu ⁇ len drove present to a flow compensation in the not shown front half being too for such purposes as.
- the illustrated position of the coil device 31 is only an exemplary embodiment in order to be able to visualize the coil device.
- the situation may also be at a different point in the scope be provided of the cylindrical member 23, for example, advantageously further back in a remote from the permanent magnet 13 region of the annularly closing magnetic flux.
- the magnetic flux which is coupled by the coil means 31 in the flux guiding element 23, not Darge provides ⁇ . Similar to Figure 2, however, this magnetic flux is intended to oppose, or at least partially compensate for, the magnetic flux 37 caused by the drone.
- the device has at least two coil devices which enclose the flux-guiding element at different points in its circumference.
- the drone's magnetic field can close in two branches in the flux-conducting element, and the magnetic field can be compensated in these two branches by the respectively associated coil devices.
- Analogously to the embodiment of figure 2 comprises the Kompensati ⁇ onsvorraum 21 also an arrangement of a sensor unit 41, with which the relative position of the UAV to Kom ⁇ pensationsvorplatz or at least one position-dependent physical characteristic may be monitored, and a regulating device 45, dependent on the from the relative
- Position a current flowing through the coil means current can be controlled.
- FIG. 4 shows a compensation device according to a further execution of the invention, also in schemati ⁇ rule longitudinal section and with introduced drone 1.
- this embodiment 21 has the compensation device a flux guiding element 23, which is designed as an open ring in the manner of a U.
- the UAV 1 is arranged in the region of the open limb of the U-shape, so ⁇ that the magnetic flux between the drone and the flux guiding element 23 may include annularly.
- the drone 1 has a single permanent magnet thirteenth on, however, the main magnetic axis, unlike the previous embodiments, is not radially but axially aligned.
- the flux guiding element 23 is here so refinedstal ⁇ tet that it with two collectors 29, which are offset in the axial Rich ⁇ tion, the magnetic flux in the radially outer region of Drone can pick up.
- this conclusion can ring-closed over the remaining part of the flux-guiding element 23, as indicated in FIG. 4 by means of the representative field line 37.
- the flux-guiding element 23 is shaped so that the middle portion of the U-shape surrounding the UAV 1 in its axial end.
- a coil device 31 is again provided, by means of which a magnetic flux for compensating the magnetic field of the drone can be coupled into the flux-guiding element 23.
- a sensor device 41 and a control device 45 are also present here.
- FIGS. 2, 3 and 4 only one permanent magnet 13 is shown in the interior of the drone 1.
- a plurality of such permanent magnets may be present within a ⁇ drone each well, and then may either be present for com pensation ⁇ and / or shielding of the magnetic field formed more separate or a superordinate Kom ⁇ pensationsvorraum 23rd
- a compensation device with a cylindrical flux-guiding element 23, similar to that shown in FIG. 3, can also be provided for the magnetic compensation of a plurality of radially aligned permanent magnets.
- a compensation Apparatus for magnetic compensation of a plurality of permanent magnets (in particular with different orientation) can also have a plurality of flux-conducting elements in the form of individual open or closed ring structures.
