Abstract

A method and a device for destruction of a warhead (11) which is even completely buried in sand, by triggering an explosive detonation in the warhead (11) by means of a hollow-charge jet (27), are to be designed so that it is possible to employ them in an environmentally safe way, whilst ensuring high efficiency. For this, the warhead (11), after its position has been located, is bombarded from a remotely controllable carrier (18). For this, the carrier (18) is equipped with a single, pivotably directable front-loader cartridge (19) for slender hollow-charge projectiles (20, 20') with percussion fuses (24) for its only small combat charge (25). The bombardment of the located target position is also carried out in a directionally stable manner by air/water, water/sand or air/sand media transfers having a linear trajectory (22), because the projectile tip (23) is designed to cause cavitation effects in the surrounding medium (17), so that a media-free cavity forms behind an end breakaway edge approximately concentrically to the trajectory (22) and therefore to the longitudinal axis of the projectile. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren bzw. eine Einrichtung gemäß dem Oberbegriff des Anspruches 1 bzw. des Anspruches 2.The invention relates to a method and a device according to the preamble of claim 1 and claim 2.

Im militärischen Alltag ist es bekannt, auf dem Grund direkt oberhalb eines beispielsweise magnetisch georteten, vollständig eingesandeten großvolumigen Kampfmittels wie etwa eines Bomben-Blindgängers oder einer Mine ein Gestell auf das Erdreich zu setzen, das eine Hohlladung in gewissem Abstand zum Grund haltert. Eine hinreichend groß ausgelegte Hohlladung dringt nach der Zündung dann mit dem Hohlladungsstrahl einige Dezimeter tief in das Erdreich ein und führt zur Detonation des Kampfmittels, wenn in dessen Einsandungs-Tiefe noch hinreichend energiereiche Strahlbestandteile die Sprengmittel-Hülle durchschlagen, um die Sprengstoff-Füllung zur Detonation zu bringen. Ob dieser angestrebte Effekt der Kampfmittel-Vernichtung jedoch tatsächlich erreicht wird, hängt stark von der Lagertiefe des Kampfmittels und der Konsinstenz des darüber befindlichen Materials ab. Auf jeden Fall ist eine recht große Vernichtungs-Ladung erforderlich, die aufgrund der Splitterwirkung bei ihrer Zündung eine ganz erhebliche Umweltgefährdung erbringt; und am Grunde eines Gewässers ist dieses Vorgehen schon deshalb nicht realisierbar, weil einerseits die genaue Positionierung der Vernichtungsladung auf dem Grund zu aufwendig wäre und andererseits die Energie des Hohlladungsstrahles beim Durchqueren des Wassers und Eindringen in den Gewässer-Grund so stark reduziert würde, daß nicht mit hinreichender Wahrscheinlichkeit eine Detonation des Kampfmittel-Sprengstoffes ausgelöst wird.In everyday military life, it is known to place a frame on the ground directly above a, for example, magnetically located, completely sunk-in, large-volume weapon, such as a bomb unexploded ordnance or a mine, which holds a shaped charge at a certain distance from the ground. A sufficiently large shaped charge then penetrates into the ground a few decimeters with the shaped charge jet and detonates the weapon when the explosive shell penetrates the explosive shell at the depth of the sand enough to detonate the explosives bring to. However, whether this desired effect of the ordnance destruction is actually achieved depends heavily on the depth of the ordnance and the consistency of the material above it. In any case, a very large destruction charge is required, which, when ignited, poses a considerable environmental hazard due to the splintering effect; and this approach is not feasible at the bottom of a body of water if, on the one hand, the exact positioning of the extermination charge on the bottom would be too complex and on the other hand the energy of the shaped charge jet when crossing the water and penetrating into the bottom of the body of water would be reduced so much that a detonation of the explosive of the weapon is not triggered with sufficient probability.

Auch der etwa auf Flughäfen geübte Beschuß eines Kampfmittels mit einer kleinkalibrigen Kanone von einem gepanzerten Fahrzeug aus ist einerseits apparativ sehr aufwendig und andererseits gegen vollständig eingesandete Kampfmittel, zumal unter dem Grunde eines Gewässers, nicht einsetzbar. Denn einerseits ist aus einer solchen Kanone kein gezielter Beschuß gegen das nicht sichtbare Kampfmittel möglich, und außerdem würde das aus einer solchen Kanone abgefeuerte Geschoß sich nicht richtungsstabil weiterbewegen, wenn es aus Luft in ein dichteres Medium wie Wasser oder gar Sand übertritt, so daß das Kampfmittel auch dann nicht getroffen würde, wenn es aufgrund bekannter Lage genau einvisiert werden könnte. Schließlich mag der Beschuß mit einer kleinkalibrigen Rohrmunition zwar zur Zerstörung des Kampfmittel-Mantels und damit dazu führen, daß das Kampfmittel nicht mehr einsatzbereit ist; geometrisch würde es dabei aber erhalten bleiben und bei der nächsten Ortung zumindest eine erhebliche Irritation auslösen, da durch die Lage-Ortung allein nicht feststellbar ist, ob das Kampfmittel noch intakt ist.Bombardment of a weapon with a small-caliber cannon from an armored vehicle, which is practiced at airports, for example, is on the one hand very expensive in terms of equipment and, on the other hand, cannot be used against fully-armed weapons, especially under the surface of a body of water. Because on the one hand, such a cannon is not capable of targeting the invisible weapon, and the projectile fired from such a cannon would not move in a directionally stable manner if it passed from air into a denser medium such as water or sand, so that Ordnance would not be hit even if it could be targeted precisely due to the known location. Finally, shelling with small-caliber barrel ammunition may destroy the weapon shell and thus lead to the weapon no longer being ready for use; Geometrically, however, it would remain intact and at least trigger a considerable irritation the next time it is located, since the position location alone cannot determine whether the weapon is still intact.

Zur Vernichtung von Seegrund-Minen ist es bekannt, mittels ferngesteuerter Unterwasser-Drohnen großvolumige Vernichtungsladungen möglichst dicht neben der aufgespürten Grundmine abzulegen und, nach Absetzen der Drohne in sichere Entfernung, ferngesteuert zu zünden. Der apparative und handhabungstechnische Aufwand dafür ist aber außerordentlich groß und die tatsächliche Vernichtungswirkung relativ ungewiß wegen nicht gezielt einsetzbarer Energie der lediglich neben dem Kampfmittel abgelegten Vernichtungsladung.For the destruction of lake bottom mines, it is known to use remote-controlled underwater drones to deposit large-volume destruction charges as close as possible to the base mine that has been found, and to fire them remotely after the drone has been set down at a safe distance. However, the expenditure in terms of apparatus and handling is extremely high and the actual destruction effect is relatively uncertain because the energy of the destruction charge, which is only stored next to the weapon, cannot be used in a targeted manner.

In Erkenntnis dieser Gegebenheiten liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Einrichtung gattungsgemäßer Art anzugeben, die ohne großen apparativen Aufwand zur sicheren Vernichtung auch - selbst unter Wasser - vollständig eingesandeter großvolumiger Kampfmittel einsetzbar sind.In recognition of these circumstances, the invention is based on the object of specifying a method and a device of the generic type which can also be used to safely destroy, even under water, large-volume warfare agents that have been completely sanded in, without great outlay on equipment.

Diese Aufgabe ist erfindungsgemäß im wesentlichen dadurch gelöst, daß bei den jeweiligen Gattungsmerkmalen auch die Kennzeichnungsmerkmale der Ansprüche 1 bzw. 2 realisiert werden.According to the invention, this object is essentially achieved in that the characterizing features of claims 1 and 2 are also realized in the respective generic features.

Nach dieser Lösung wird die vergleichsweise sehr kleine Wirkmasse eines schlanken Hohlladungs-Projektils, das aus einer billigen Frontlader-Kartusche abgeschossen werden kann, in direkter Wirkrichtung unmittelbar an der Kampfmittel-Mantelfläche ausgelöst, nachdem es das umgebende Medium - einschließlich einer Sandschicht - mit stabiler Ballistik aufgrund vollkavitierender Projektil-Geometrie durchdrungen hat. Die verbleibende große Auftreffenergie auf das Kampfmittel führt zum sicheren Ansprechen eines billigen da einfachen Aufschlagzünders. Die ohnehin kleinen und infolge der kleinen Wirkmasse auch nicht hochenergetischen Splitter, die beim Zünden des Vernichtungs-Projektils entstehen, stellen eine allenfalls geringe Umweltgefährdung dar, die durch die umgebende Sandmasse auch noch wirksam gedämpft ist. Deshalb kann der Träger der richtbaren Projektil-Abschußkartusche in der einmal erreichten Schußposition verbleiben, um erforderlichenfalls noch ein zweites Projektil für zuverlässige Vernichtung des Kampfmittels nachzufeuern, das nachgeladen oder in einem parallelen Abschußrohr bereitgehalten wird.According to this solution, the comparatively very small active mass of a slim shaped charge projectile, which can be fired from a cheap front-loading cartridge, is triggered in a direct direction of action directly on the surface of the weapon after the surrounding medium - including a layer of sand - with stable ballistics due to fully cavitating projectile geometry. The remaining large impact energy on the weapon leads to the safe response of a cheap, simple impact detonator. The anyway small and due to the small active mass also not high-energy splinters, which arise when the projectile is fired, represent at most a low environmental hazard, which is also effectively dampened by the surrounding sand mass. Therefore, the wearer of the directional projectile firing cartridge can remain in the firing position once it has been reached, in order, if necessary, to fire a second projectile for reliable destruction of the weapon, which is reloaded or kept ready in a parallel launch tube.

Zwar ist es aus der DE-PS 36 26 434 bekannt, großvolumige Seegrundminen durch Miniatur-Hohlladungsgefechtsköpfe außer Funktion zu setzen, die über die am Grund geortete Mine ausgestreut werden und deren Verdämmung durchbrechen sowie Krater in den Sprengstoff einbrennen, ohne diesen gleich zur Detonation zu bringen. Aufgrund der niedrigen Auftreffgeschwindigkeit sind diese Gefechtsköpfe aber mit einer recht aufwendigen Zündeinrichtung auszustatten, und gegen vollständig eingesandete Minen sind derartige bloß ins Wasser ausgestreute Miniatur-Gefechtsköpfe wirkungslos.It is known from DE-PS 36 26 434 to disable large-volume seabed mines by miniature shaped charge warheads, which are scattered over the mine located at the bottom and break through its insulation and burn craters into the explosives without detonating them immediately bring. Because of the low Impact velocity, these warheads are to be equipped with a rather complex ignition device, and such miniature warheads, which are merely scattered into the water, are ineffective against completely sanded mines.

Aus der DE-AS 23 60 226 schließlich ist es bekannt, daß als Zünder für eine ummantelte Sprengladung eine verschwenkbar auf deren Mantelfläche montierte Hohlladung einsetzbar ist. Eine solche konstruktive Anbringung einer Hohlladung ist jedoch nicht möglich, wenn vollständig eingesandete Gefechtsmittel zerstört werden sollen.Finally, it is known from DE-AS 23 60 226 that a shaped charge which can be pivoted to the outer surface of the shell can be used as the detonator for a coated explosive charge. However, such a structural attachment of a shaped charge is not possible if completely slaughtered combat agents are to be destroyed.

Zusätzliche Alternativen und Weiterbildungen sowie weitere Merkmale und Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und, auch unter Berücksichtigung der Darlegungen in der Zusammenfassung, aus nachstehender Beschreibung eines in der Zeichnung unter Beschränkung auf das Wesentliche stark abstrahiert skizzierten Einsatz- und Funktionsbeispiels für die erfindungsgemäße Lösung. Die einzige Figur der Zeichnung zeigt in Aufriß-Darstellung einen Kartuschen-Träger, von dem aus eine eingesandete Mine mit einem Projektil voll-kavitierender Geometrie und mit Aufschlagzünder für seine Hohlladung beschossen wird.Additional alternatives and further developments as well as further features and advantages of the invention result from the further claims and, also taking into account the explanations in the summary, from the following description of an example of use and function of the invention according to the invention, which is sketched in a highly abstracted manner while restricting it to the essentials Solution. The only figure in the drawing shows an outline of a cartridge carrier, from which a sanded mine is shot at with a projectile of fully cavitating geometry and with a detonator for its shaped charge.

Bei dem zu vernichtenden Kampfmittel 11 handelt es sich um einen relativ großvolumigen, im wesentlichen zylindrischen Körper mit einem Metallmantel 12 von recht geringer Wandstärke im Verhältnis zum Kampfmittel-Durchmesser 13, der im wesentlichen mit Sprengstoff 14 gefüllt ist. Das Kampfmitel 11, etwa eine Seegrundmine, liegt vollständig in Sand 15 vergraben, eingesandet in einer Tiefe unter dem Grund 16, die mindestens in der Größenordnung des Zylinder-Durchmessers 13 liegen und sogar einige Meter betragen kann. Beim Medium 17 über dem Grund 16 kann es sich um Wasser, aber auch um Luft handeln; so daß es sich beim Grund 16 um einen Gewässergrund oder um den Boden an Luft handeln kann. Die örtliche Position des eingesandeten Kampfmittels 11 längs des Grundes 16 ist mittels einer beispielsweise magnetischen Ortungseinrichtung (in der Zeichnung nicht berücksichtigt) lokalisierbar, die in oder über dem Medium 17 oberhalb des Grundes 16 arbeitet.The weapon 11 to be destroyed is a relatively large-volume, essentially cylindrical body with a metal jacket 12 of relatively small wall thickness in relation to the weapon diameter 13, which is essentially filled with explosive 14. The fighting medium 11, for example a sea bed mine, is completely buried in sand 15, seared at a depth below the bottom 16, which is at least in the order of magnitude of the cylinder diameter 13 and can even be a few meters. The medium 17 above the base 16 can be water, but also air; so that it is Reason 16 can be a body of water or the ground in air. The local position of the sanded-in weaponry 11 along the base 16 can be localized by means of, for example, a magnetic location device (not taken into account in the drawing), which operates in or above the medium 17 above the base 16.

Wenn das zu vernichtende Kampfmittel 11 lokalisiert ist, wird ein Träger 18 für eine einfache, beispielsweise als Frontlader ausgebildete, Kartusche 19 etwas seitlich neben die Position des Kampfmittels 11 manövriert und die mit einem Projektil 20 geladene Kartusche 19 mittels einer Schwenk-Richteinrichtung 21 räumlich so ausgerichtet, daß nach den trigonometrischen Gesetzmäßigkeiten die lineare Projektil-Schußbahn 22 das zuvor geortete Kampfmittel 11 möglichst mittig trifft. Die Spitzen- und Hüllengeometrie des Vernichtungs-Projektils 20, 20' ist in als solcher bekannter Weise derart ausgelegt, daß sich jedenfalls bei rascher Bewegung durch Wasser eine medienfreie Kavitationshülle direkt hinter der Projektil-Spitze 23 einstellt; vgl. US-PS 34 34 425, Fig. 5, jedoch mit viel kleinerem Durchmesser der umlaufenden Stirnkante im Verhältnis zum größten Projektil-Durchmesser, so daß sich eine diesem eng benachbarten Phasengrenze von der Kavitationshülle zum Wasser einstellt. Dadurch findet keine Berührung des umgebenden Mediums (Wasser) mit der zylindrischen Mantelfläche des Projektils hinter seiner Spitze 23 statt, so daß das Projektil 20, 20' sich, gegebenenfalls heckseitig die Kavitationshülle seitlich touchierend um eine Auslenkung rückgängig zu machen, richtungsstabil durch das Umgebungs-Medium 17 längs der Schußbahn 22 bewegt. Diese strömungsdynamischen Verhältnisse bleiben auch dann bestehen, wenn ein Übergang der Schußbahn 22 und damit des Projekils 20, 20' in ein gegenüber Luft noch dichteres Medium als Wasser wie insbesondere in Sand 15 erfolgt: Auch hierin bewirkt die auf Kavitationserzeugung ausgelegte Geometrie der Projektil-Spitze 23 die Verdrängung des Umgebungsmaterials, so daß eine spitzkegelige bis zylindrische medienfreie Zone sich längs des Projektils 20, 20' um seine Wandung erstreckt und dadurch auch im Sand 15 eine praktisch richtungsstabile Fortbewegung des Projektils 20, 20' gewährleistet bleibt.When the weapon 11 to be destroyed is located, a carrier 18 for a simple cartridge 19, for example designed as a front loader, is maneuvered somewhat to the side next to the position of the weapon 11 and the cartridge 19 loaded with a projectile 20 is spatially so by means of a swivel-straightening device 21 aligned that, according to the trigonometric laws, the linear projectile shot 22 hits the previously located weapon 11 as centrally as possible. The tip and shell geometry of the annihilation projectile 20, 20 'is designed in a manner known per se such that, in any case, a media-free cavitation shell is formed directly behind the projectile tip 23 when moving rapidly through water; see. US-PS 34 34 425, Fig. 5, but with a much smaller diameter of the circumferential end edge in relation to the largest projectile diameter, so that a closely adjacent phase boundary from the cavitation shell to the water is established. As a result, the surrounding medium (water) does not come into contact with the cylindrical outer surface of the projectile behind its tip 23, so that the projectile 20, 20 ', possibly touching the cavitation sleeve on the rear side in order to undo a deflection, is directionally stable by the surrounding Medium 17 moved along the weft 22. These dynamic flow conditions also remain when the weft path 22 and thus the projectile 20, 20 'transition into a medium which is even denser than air, such as water, in particular in sand 15: Here too, the geometry of the projectile tip, which is designed to generate cavitation, causes 23 the displacement of the surrounding material, so that a tapered to cylindrical media-free zone extends along the projectile 20, 20 'around its wall, thereby ensuring that the projectile 20, 20' moves in a directionally stable manner even in the sand 15.

Deshalb trifft das einmal mittels der schwenk-richtbaren Kartusche 19 bezüglich der vorher detektierten Lage des zu vernichtenden Kampfmittels 11 in korrekter Richtung abgeschossene Projektil 20, 20' mit hoher Auftreffgeschwindigkeit auch noch ein recht tief eingesandetes Kampfmittel 11. Die hohe Auftreffgeschwindigkeit garantiert ein sicheres Ansprechen eines Aufschlagzünders 24, der als Heckzünder ausgestaltet sein kann, vorzugsweise aber in der Projektil-Spitze 23 angeordnet ist. Der Zünder 24 initiiert die Gefechtsladung 25 hinter einer (spitzkegeligen) Hohlladungs-Einlage 26, die in bekannter Weise zu einem extrem hochenergetischen Hohlladungs-Strahl 27 umgeformt wird. Diese durchdringt mühelos den Kampfmittel-Mantel 12 unabhängig davon, ob er schon durch die kinetischen Energie des aufprallenden Projektils 20' beschädigt wurde, und dringt tief in den Kampfmittel-Sprengstoff 14 hinein, der dadurch relativ großvolumig angezündet und so zur Detonation gebracht wird.For this reason, once the projectile 20, 20 ', which is shot in the correct direction with respect to the previously detected position of the weapon 11 to be destroyed, is hit by the pivotable cartridge 19 with a high impact velocity and a very deeply emitted weapon 11. The high impact velocity guarantees a reliable response of one Impact detonator 24, which can be configured as a rear detonator, but is preferably arranged in the projectile tip 23. The igniter 24 initiates the combat charge 25 behind a (pointedly tapered) shaped charge insert 26, which is converted into an extremely high-energy shaped charge beam 27 in a known manner. This effortlessly penetrates the weapon shell 12 regardless of whether it has already been damaged by the kinetic energy of the impacting projectile 20 'and penetrates deeply into the weapon explosive 14, which is thereby ignited in a relatively large volume and thus detonated.

Dadurch wird das Kampfmittel 11 sicher vernichtet; wobei die darübergelegene Schicht des Sandes 15 die Umgebungswirkung einer bei der Detonation unvermeidlichen Splitterbildung wirksam dämpft. Dadurch ist der in die Nähe des Detonationsherdes in Abschußposition verbrachte Kartuschen-Träger 18 gut gegen Beschädigungen geschützt, so daß er aus einem parallelen Rohr oder nach Nachladen der Kartusche mit einem neuen Kampfmittel-Vernichtungsprojektil 20 erneut eingesetzt werden kann. Da jedoch der Träger 18 nicht mit eigenen teueren Ortungseinrichtungen ausgestattet sein muß, denn er wird ja in eine Wirkposition nach Maßgabe des anderweitig zuvor lokalisierten Kampfmittels gesteuert, kann es sich auch um ein Verlustgerät handeln; d.h., der wirtschaftliche Verlust ist nicht zu groß, wenn aufgrund der Detonation des Kampfmittels 11 Druckwellen oder Splitterwirkungen ausgelöst werden, die die weitere Funktionsbereitschaft des Kartuschen-Trägers 18 ernsthaft beeinträchtigen können.As a result, the weapon 11 is safely destroyed; the overlying layer of sand 15 effectively dampens the environmental effect of splinter formation unavoidable during detonation. As a result, the cartridge carrier 18, which has been brought into the vicinity of the detonation focus in the firing position, is well protected against damage, so that it can be used again from a parallel tube or after reloading the cartridge with a new weapon projectile 20. However, since the carrier 18 does not have to be equipped with its own expensive locating devices, since it is steered into an operative position in accordance with the ordnance previously located otherwise, it can also be a loss device; that is, the economic loss is not too great if pressure waves or splinter effects are triggered due to the detonation of the weapon 11, which can seriously impair the further operational readiness of the cartridge carrier 18.

Wenn es sich beim Medium 17 oberhalb des Grundes 16 um Wasser handelt, ist der Kartuschen-Träger 18 als fernsteuerbares Fahrzeug in Form eines Verdrängerschiffes, vorzugsweise eines Tauchbootes ausgelegt. Wie in der Prinzipskizze der Zeichnung durch Teleskopbeine 28 symbolisch vereinfacht berücksichtigt, kann vorgesehen sein, die Abschußposition nach Verbringung in die Nähe des Fundortes des zu vernichtenden Kampfmittels 11 mechanisch zu fixieren und dann erst die Feinausrichtung der Projektil-Schußbahn 22 mittels der verschwenkbaren Kartusche 19 durchzuführen, um hierfür genügend Operationszeit bei mechanisch arretierter Träger-Position verfügbar zu haben. Wenn es sich beim Medium 17 oberhalb des Sandes 15 um Luft handelt, kann der Kartuschen-Träger 18 als unmittelbar auf dem Grund 16 selbstfahrendes oder geschlepptes Landfahrzeug ausgebildet sein.If the medium 17 above the bottom 16 is water, the cartridge carrier 18 is designed as a remotely controllable vehicle in the form of a displacement vessel, preferably a submersible. As symbolically simplified in the schematic diagram of the drawing by means of telescopic legs 28, provision can be made to mechanically fix the firing position after being brought into the vicinity of the location of the weapon 11 to be destroyed and only then to carry out the fine alignment of the projectile weft track 22 by means of the pivotable cartridge 19 in order to have enough operating time for this with the carrier position locked mechanically. If the medium 17 above the sand 15 is air, the cartridge carrier 18 can be designed as a self-propelled or towed land vehicle directly on the ground 16.
