Description

Die Erfindung betrifft eine umschaltbare zylindrische Wirkladung eines Gefechtskopfes mit einer innerhalb der Sprengladung angeordneten Halterung für eine Vielzahl verteilt angeordneter Pellets, die aus einem rohrförmigen Teil und einem senkrecht zur Hauptachse der Wirkladung angeordneten scheibenförmigen Teil besteht, sowie wenigstens zwei Zündeinrichtungen für eine Sprengladung mit einer geformten Einlage.The invention relates to a switchable cylindrical active charge of a warhead with an arranged inside the explosive charge holder for a plurality of distributed arranged pellets, which consists of a tubular part and a perpendicular to the main axis of the active charge disc-shaped part, and at least two igniters for a charge with a shaped Inlay.

Das zukünftige Einsatzspektrum von Waffen in sich verändernden Szenarien erfordert eine neue Munition, die gleichermaßen Punkt- oder auch Flächenziele wirkungsvoll bekämpfen kann. Unter Beachtung der Anforderung an Minimierung von Kollateralschäden sind Munitionsarten mit dosierbarer und/oder umschaltbarer Wirkung von besonderem Interesse.The future use of weapons in changing scenarios requires a new ammunition, which can equally effectively combat point or surface targets. Taking into account the requirement to minimize collateral damage, ammunition types with metered and / or reversible action are of particular interest.

Von der Anmelderin sind bereits verschiedene Konzepte multifunktionaler Wirkladungen angemeldet worden, die sich bereits bewährt haben.The applicant has already filed various concepts of multifunctional active charges, which have already proven themselves.

Aus der DE 10 2006 018 687 A1 ist eine umschaltbare Ladung bekannt geworden. Innerhalb der Sprengladung ist eine scheibenförmige, etwa senkrecht zur Hauptachse angeordnete inerte Halterung mit einer Vielzahl von Pellets angeordnet. Alternativ dazu wird vorgeschlagen, eine rohrförmige Halterung für eine Vielzahl von Pellets innerhalb der Sprengladung anzuordnen. Weitere Anordnungen werden hier jedoch nicht beschrieben und waren im Rahmen der gegebenen Aufgabenstellung auch nicht erforderlich.From the DE 10 2006 018 687 A1 a reversible charge has become known. Within the explosive charge, a disc-shaped, approximately perpendicular to the main axis arranged inert holder is arranged with a plurality of pellets. Alternatively, it is proposed to arrange a tubular holder for a plurality of pellets within the explosive charge. However, further arrangements are not described here and were not required within the scope of the given task.

Die EP-A-1 912 037 beschreibt eine zylindrische Wirkladung mit einer Splitter bildenden Hülle, in deren Wirkladung eine rohrförmige Halterung für mit Sprengstoff gefüllte Pellets angeordnet ist, wobei die Initiierung der Wirkladung von unterschiedlichen Stellen entlang der Hauptachse erfolgen kann.The EP-A-1 912 037 describes a cylindrical active charge with a splitter-forming shell, in whose effective charge a tubular support for explosive-filled pellets is arranged, wherein the initiation of the effective charge can take place from different points along the main axis.

Es ist Aufgabe der vorliegenden Erfindung, ein multifunktionales Wirksystem anzugeben, welches eine wahlweise Umschaltung verschiedener Wirkungsarten in axialer und in radialer Richtung ermöglicht.It is an object of the present invention to provide a multifunctional active system, which allows an optional switching of different modes of action in the axial and in the radial direction.

Diese Aufgabe wird in überraschend einfacher Weise dadurch gelöst, dass der rohrförmige und der senkrechte Teil der Halterung der Pellets aneinander anliegen oder miteinander verbunden sind, wobei der scheibenförmige Teil in einem vorbestimmten Abstand von einer Einlage angeordnet ist, und wobei der rohrförmige Teil auf der der Einlage gegenüber liegenden Seite des scheibenförmigen Teils angeordnet ist, und dass innerhalb des rohrförmigen Teils entlang der Hauptachse der Wirkladung an je nach beabsichtigter Wirkung eine erste Zündeinrichtung an unterschiedlichen Stellen angeordnet ist und im Zentrum des scheibenförmigen Teils der Halterung eine weitere Zündeinrichtung angeordnet ist.This object is achieved in a surprisingly simple manner in that the tubular and the vertical part of the support of the pellets abut each other or are connected to each other, wherein the disc-shaped part is arranged at a predetermined distance from an insert, and wherein the tubular part on the Insert opposite side of the disc-shaped part is arranged, and that within the tubular part along the main axis of the active charge on depending on the intended effect, a first ignition device is disposed at different locations and in the center of the disc-shaped part of the holder, a further ignition device is arranged.

Aufgrund der erstmalig so vorgeschlagenen Anordnung eines zylinderförmigen und eines scheibenförmigen Halters für Pellets ist es möglich, in Stufen die Art der Wirkungsentfaltung und deren Richtung bedarfsweise anzupassen.Due to the first time so proposed arrangement of a cylindrical and a disc-shaped holder for pellets, it is possible to adjust in stages, the nature of the effect development and their direction as needed.

In vorteilhafter Weise ist eine der Zündeinrichtungen im Zentrum des senkrechten Teils der Halterung angeordnet. Diese ermöglicht die Ausbildung eines EFP-Projektils im Fall der Zündung.Advantageously, one of the ignition devices is arranged in the center of the vertical part of the holder. This allows the formation of an EFP projectile in the case of ignition.

Als vorteilhafte Ausgestaltung wird weiterhin vorgeschlagen dass entlang der Hauptachse der Wirkladung im Sprengstoff eine von der der Einlage gegenüber liegenden Seite bis etwa zum scheibenförmigen Teil der Halterung sich erstreckende Ausnehmung angeordnet ist, in der wenigstens eine Zündeinrichtung mit Hilfe eines Antriebs verschiebbar gelagert ist.As an advantageous embodiment, it is further proposed that along the main axis of the active charge in the explosive one of the insert opposite side is arranged approximately to the disk-shaped part of the holder extending recess in which at least one ignition device is slidably mounted by means of a drive.

Damit wird erreicht, dass je nach gewähltem Ort der Zündeinrichtung in Fall der Zündung die Größen der in axialer und radialer Richtung abgegebenen Splitter in weiten Grenzen bestimmbar sind.This ensures that, depending on the selected location of the ignition device in the case of ignition, the sizes of the votes in the axial and radial directions splitter can be determined within wide limits.

Eine andere Ausgestaltung ist dadurch bestimmt, dass am der Einlage zugewandten Ende der Ausnehmung eine Dämpfungsschicht angeordnet ist. Dadurch wird die Ausbreitung der Detonationsfront, die von der in der Ausnehmung gezündeten Zündeinrichtung stammt, vor dem Eintreffen an der im scheibenförmigen Teil des Halters befindlichen Zündeinrichtung verzögert und in der Amplitude gemindert.Another embodiment is determined by the fact that a damping layer is arranged on the insert facing the end of the recess. As a result, the propagation of the detonation front, which originates from the ignition device ignited in the recess, is delayed before arrival at the ignition device located in the disk-shaped part of the holder and reduced in amplitude.

In der Figur 1 ist der prinzipielle Aufbau einer umschaltbaren Wirkladung 1 vereinfacht dargestellt. Die Sprengladung 8 ist radial außenseitig von einer Splitter bildenden Hülle 11 umgeben, die beispielsweise aus Metall bestehen kann und entweder keine die Ausbildung der Splitter unterstützenden Kerbungen aufweist oder auch vorgekerbt ist. Die Wirkladung ist in Schussrichtung mit einer Einlage 5 abgeschlossen. Auf der Hauptachse 6 der Wirkladung 1 sind an der Einlage 5 gegenüber liegenden Seite und auch innerhalb der Sprengladung 8 an verschiedenen Positionen 7a, 7b, 7c eine oder mehrere Zündketten ZK1 angeordnet. Diese können innerhalb der Ladung fest positioniert sein und auch, wie in Figur 1 gezeigt, innerhalb einer längs der Hauptachse 6 verlaufenden Ausnehmung 12 in der dargestellten Pfeilrichtung verschiebbar angeordnet sein. Wesentlich für die Umschaltbarkeit der Wirkladung ist hierbei die freie Wahl des Ortes der Initiierung der Zündkette ZK1. Weiterhin ist die Möglichkeit vorgesehen, die weitere Zündkette ZK2 als Hilfsmittel bei der Initiierung der ersten Zündkette ZK1 zu nutzen oder die weitere Zündkette ZK2 allein zu initiieren. Es ist genauso möglich mehrere Zündketten ZK1 fest zu installieren, die wahlweise initiierbar sind. Dabei kann die Ausnehmung 12 vollständig weggelassen werden.In the FIG. 1 is the basic structure of a switchable active charge 1 simplified. The explosive charge 8 is surrounded radially on the outside by a fragment forming sheath 11, which may for example consist of metal and either has no formation of the splitter supporting notches or is also pre-scored. The active charge is completed in the weft direction with an insert 5. On the main axis 6 of the active charge 1 are on the insert. 5 opposite side and also within the explosive charge 8 at different positions 7a, 7b, 7c one or more igniter ZK1 arranged. These can be firmly positioned within the cargo and also, as in FIG. 1 shown to be slidably disposed within a recess 12 extending along the main axis 6 in the illustrated arrow direction. Essential for the switchability of the active charge here is the free choice of the place of initiation of the ignition ZK1. Furthermore, the possibility is provided to use the further ignition chain ZK2 as an aid in the initiation of the first ignition chain ZK1 or to initiate the further ignition chain ZK2 alone. It is just as possible to install several ignition chains ZK1, which can be optionally initiated. In this case, the recess 12 can be completely omitted.

Weiterhin ist innerhalb der Sprengladung 8 eine einteilige oder auch mehrteilige Halterung 2, 3 für Pellets 4a, 4b angeordnet. Diese Halterung besteht aus inertem Kunststoffmaterial und weist verteilt angeordnete Pellets 4a, 4b auf, die aus Sprengstoff bestehen. Der radiale Teil 2 der Halterung ist in der Form eines Rohres rotationssymmetrisch um die Hauptachse 6 im Sprengstoff 8 angeordnet und weist zur Hülle 11 einen Abstand in der Größenordnung einiger Pelletsdurchmesser auf. Der etwa senkrecht zur Hauptachse 6 angeordnete scheibenförmige Teil 3 der Halterung weist ebenfalls eine Vielzahl verteilt angeordneter gleichartiger Pellets 4b auf. Im Bereich der Hauptachse 6 kann in diesem Teil der Halterung 3 die weitere Zündkette ZK2 angeordnet sein. Der Abstand zwischen dem scheibenförmigen Teil 3 der Halterung und der Einlage 5 ist so groß bemessen, dass der im Fall der Initiierung der Zündkette ZK1, der Pellets im scheibenförmigen Teil der Halterung und auch der Zündkette ZK2 hinsichtlich der örtlichen Druckverteilung stark modifizierten Detonationswelle genügend Laufstrecke zur Verfügung steht um die Einlage 5 in gewünschter Weise zu fragmentieren.Furthermore, within the explosive charge 8, a one-piece or multi-part holder 2, 3 for pellets 4a, 4b arranged. This holder is made of inert plastic material and has distributed pellets 4a, 4b, which consist of explosives. The radial part 2 of the holder is arranged in the form of a tube rotationally symmetrical about the main axis 6 in the explosive 8 and has the shell 11 at a distance in the order of some pellet diameter. The approximately perpendicular to the main axis 6 arranged disc-shaped part 3 of the holder also has a plurality of distributed arranged similar pellets 4b. In the region of the main axis 6, the further ignition chain ZK2 can be arranged in this part of the holder 3. The distance between the disc-shaped part 3 of the holder and the insert 5 is dimensioned so large that in the case of initiation of the ignition chain ZK1, the pellets in the disc-shaped part of the holder and the ignition chain ZK2 greatly modified with respect to the local pressure distribution detonation wave enough running distance Available to fragment the insert 5 in the desired manner.

Grundsätzlich kann die Wirkladung in vier unterschiedlichen Moden ausgelöst werden, die im Folgenden näher beschrieben werden. In der Figur 2 ist der Modus zur gleichzeitigen Erzeugung radial abgehender natürlicher Splitter und axial abgehender kontrolliert erzeugter Splitter dargestellt. Der Begriff natürliche Splitter wird für diejenigen Splitter verwendet, die ohne Zuhilfenahme von Mitteln erzeugt werden, die die Form und/oder Größe der Splitter bei deren Entstehung beeinflussen. Kontrolliert erzeugte Splitter werden dagegen gezielt in der Entstehungsphase hinsichtlich ihrer Form und/oder Größe beeinflusst.In principle, the effective charge can be triggered in four different modes, which are described in more detail below. In the FIG. 2 is the mode for the simultaneous generation of radially outgoing natural splinters and axial outgoing controlled generated splitter shown. The term natural splinters is used for those splinters that are generated without the aid of agents that affect the shape and / or size of the splinters as they form. Controlled splinters, on the other hand, are specifically influenced in the formation phase in terms of their shape and / or size.

Wie in Figur 2 gezeigt wird die Zündkette ZK1 in der bereits in Figur 1 angedeuteten Position 7a initiiert. Die Front der Detonationswelle DW durchläuft den Sprengstoff 8 in Richtung der Einlage 5. Ihr Verlauf ist in den Phasen A, .. , D dargestellt. Sie streift hierbei den rohrförmigen Teil der Halterung 2, wodurch die in der Halterung gelagerten Pellets 4a zwar initiiert werden, aber das beeinflusst die Detonationswelle zwischen Halterung 2 und Hülle 11 nicht. Im Kontaktbereich der Detonationswelle DW mit der Hülle 11 wird diese in natürliche Splitter 13a zerlegt, die radial zur Hauptachse 6 abgehen. Es ist natürlich auch möglich, eine vorgekerbte Hülle oder gleichwirkende Einrichtung zur Erzeugung kontrollierter Splitter zu verwenden.As in FIG. 2 the ignition chain ZK1 is shown in the already in FIG. 1 indicated position 7a initiated. The front of the detonation wave DW passes through the explosive 8 in the direction of the insert 5. Its course is shown in the phases A, .., D. It strips the tubular part of the holder 2, whereby the pellets 4a stored in the holder are indeed initiated, but this does not affect the detonation wave between the holder 2 and the casing 11. In the contact area of the detonation wave DW with the shell 11, this is decomposed into natural splinters 13 a, which depart radially to the main axis 6. Of course, it is also possible to use a pre-notched sheath or equivalent means to create controlled fragments.

Eine geringfügige Deformation der Detonationswelle DW findet beim Durchgang durch die Dämpfungsschicht 10 statt. Beim Erreichen des scheibenförmigen Halters 3 initiiert die Front der Detonationswelle DW die darin gelagerten Pellets 4b. Daraus ergibt sich eine Überlagerung der ursprünglichen Detonationswelle DW mit denjenigen, die von den Pellets erzeugt werden. Dadurch entsteht ein sich aus der Anordnung der Pellets ergebendes Muster von Druckspitzen, welche schließlich die Einlage 5 in kontrollierte Splitter 14a zerlegt. Da die Detonationsfront etwa frontal auf die Einlage 5 trifft, gehen diese Splitter relativ stark gebündelt in axialer Richtung ab.A slight deformation of the detonation wave DW takes place when passing through the damping layer 10. Upon reaching the disc-shaped holder 3, the front of the detonation wave DW initiates the pellets 4b stored therein. This results in a superposition of the original detonation wave DW with those generated by the pellets. This results in a pattern of pressure peaks resulting from the arrangement of the pellets, which finally breaks up the insert 5 into controlled splinters 14a. Since the detonation front strikes the insert 5 approximately frontally, these splinters go bundled relatively axially in the axial direction.

In der Figur 3 ist ein weiterer einstellbarer Modus dargestellt, in dem in radialer Richtung kontrollierte Splitter und in axialer Richtung kontrollierte gebündelte Splitter erzeugt werden können. Es wird eine Zündkette ZK1 für die Initiierung gewählt, die in einer Position 7b etwa in der Mitte zwischen der Lage der Zündkette ZK1 aus der Figur 2 und der scheibenförmigen Halterung 3 liegt. Die hierbei erzeugte Front der Detonationswelle DW breitet sich von dort etwa radial aus, was durch die verschiedenen Phasen A, B, C der Detonationswelle dargestellt ist. In der Phase B durchdringt sie den rohrförmigen Teil der Halterung 2 und den scheibenförmigen Teil 3 der Halterung und initiiert dabei die Pellets 4a und 4b. Dadurch wird der Front der Detonationswelle DW das entsprechende Detonationswellenmuster C aufgeprägt. Dies führt dazu, dass die Hülle 11 kontrolliert in dieses Muster zerlegt wird. Im Fall großer vorgeformter Splitter werden diese in entsprechend kleinere Splitter zerlegt. Der scheibenförmige Teil der Halterung wird in ähnlicher Weise, wie bereits zu Figur 2 beschrieben, etwa frontal beaufschlagt. Dies führt auch hier zur Aufprägung eines Detonationswellenmusters und zur entsprechenden Zerlegung der Einlage 5 in kontrollierte Splitter 14a, die ebenso gebündelt abgehen.In the FIG. 3 Another adjustable mode is shown, in which radially controlled splitter and axially controlled bundled splitter can be generated. A firing chain ZK1 is chosen for the initiation, which in a position 7b approximately in the middle between the position of the ignition chain ZK1 from the FIG. 2 and the disc-shaped holder 3 is located. The generated here front of the detonation wave DW extends from there approximately radially, which is represented by the different phases A, B, C of the detonation wave. In phase B it penetrates the tubular part of the holder 2 and the disc-shaped part 3 of the holder, thereby initiating the pellets 4a and 4b. As a result, the front of the detonation wave DW is impressed with the corresponding detonation wave pattern C. This results in the sheath 11 being dissected into this pattern in a controlled manner. In the case of large preformed splinters these are broken down into smaller splinters. The disc-shaped part of the holder is in a similar manner as already FIG. 2 described, about frontal impacted. This also leads to the imprinting of a detonation wave pattern and to the corresponding decomposition of the insert 5 into controlled splinters 14a, which likewise go bundled.

In der Figur 4 ist ein anderer einstellbarer Modus dargestellt, in dem in radialer Richtung kontrollierte Splitter und in axialer Richtung kontrollierte Splitter mit aufgeweiteter Ausbreitungsrichtung erzeugt werden können. Es wird eine Zündkette ZK1 für die Initiierung gewählt, die in einer Position 7c noch näher an der weiteren Zündkette ZK2 liegt, als dies in Figur 3 beschrieben worden war. Beide Teile der Halterung werden in entsprechender Weise von der Front der Detonationswelle DW durchlaufen, was mittels der Phasen A, B, C dargestellt ist. In radialer Richtung werden Splitter etwa in der gleichen Weise wie bereits beschrieben erzeugt. Da der Ort der Initiierung der Sprengladung jedoch näher an der Einlage 5 liegt, ist die Front der Detonationswelle stärker gekrümmt. Dies führt zu einer etwas anderen Größenverteilung der kontrolliert erzeugten Splitter 14b und zu einem aufgeweiteten Abgangsbereich der Splitter.In the FIG. 4 another adjustable mode is shown in which radially controlled splitter and axially controlled splitter with expanded propagation direction can be generated. A firing chain ZK1 is chosen for the initiation, which in a position 7c is even closer to the further firing chain ZK2 than in FIG FIG. 3 had been described. Both parts of the holder are traversed in a corresponding manner from the front of the detonation wave DW, which is represented by the phases A, B, C. In the radial direction splinters are generated in about the same way as already described. However, since the location of the initiation of the explosive charge is closer to the insert 5, the front of the detonation wave is more curved. This leads to a slightly different size distribution of the splitter 14b, which has been generated in a controlled manner, and to a widened outflow region of the splinters.

Die Figur 5 zeigt schließlich einen einstellbaren Modus zur Erzeugung natürlicher Splitter in radialer Richtung und eines Projektils in axialer Richtung. Hierbei wird die Zündkette ZK2 initiiert, die im unmittelbaren Bereich oder in der scheibenförmigen Halterung 3 angeordnet ist. Die Front der Detonationswelle DW läuft unmittelbar auf die Einlage 5 auf, wodurch diese in ein Projektil 15 umgeformt wird. Alle Pellets 4a, 4b in den beiden Halterungen 2 und 3 werden von der Front nur streifend getroffen, weshalb die Initiierung der Pellets zwar erfolgt, aber dies die Detonationswelle zwischen Halterung und Hülle nicht beeinflusst. Die Hülle zerlegt sich deshalb in natürliche Splitter. In Fall vorgeformter Splitter werden diese nur radial beschleunigt.The FIG. 5 finally shows an adjustable mode for generating natural splitter in the radial direction and a projectile in the axial direction. Here, the ignition chain ZK2 is initiated, which is arranged in the immediate area or in the disc-shaped holder 3. The front of the detonation wave DW runs directly on the insert 5, whereby it is converted into a projectile 15. All pellets 4a, 4b in the two brackets 2 and 3 are from the front only grazing struck, which is why the initiation of the pellets done, but this does not affect the detonation wave between the holder and shell. The shell therefore decomposes into natural splinters. In the case of preformed fragments these are only accelerated radially.
