Description

Die Erfindung betrifft einen Gefechtskopf gemäß dem Gattungsbegriff des Anspruchs 1.The invention relates to a warhead according to the preamble of claim 1.

Ein Gefechtskopf mit zwei hintereinander angeordneten Wirkladungen ist in der EP-A-0 201 433 beschrieben. Diese Druckschrift stellt einen stand der Technik gemäß Artikel 54(3) EPÜ dar. Die darin beschriebene Tandem-Hohlladungsanordnung weist eine durchmesserverkleinerte Vorhohlladung und eine dahinter angeordnete Haupthohlladung großen Durchmessers mit jeweils einer spitzkegelförmigen Hohlladungsauskleidung auf. Die Zündung der beiden Hohlladungen erfolg mit geringer Zeitverzögerung durch einen Zünder. Zur Vermeidung, daß sich die Detonation der Vorhohlladung zu negativ auf die Ausbildung des Strahles aus der Haupthohlladung auswirkt, ist zwischen Vorhohlladung und Haupthohlladung eine Dämpfungsanordnung vorgesehen. Periphere Bauteile, wie ein gyroskopisches Leitsystem, ein optischer Zielerfassungssensor, eine elektrische Versorgungseinheit und Zünd- und Sicherungseinrichtungen sind gleichfalls zum Schutz der Haupthohlladung im Umfangsbereich um ein zentrales Kanalrohr zur freien Ausbildung des Haupthohlladungsstrahles sowie um die Vorhohlladung selbst angeordnet.A warhead with two active charges arranged one behind the other is described in EP-A-0 201 433. This document represents a state of the art according to Article 54 (3) EPC. The tandem shaped charge arrangement described therein has a pre-shaped charge of reduced diameter and a main shaped charge of large diameter arranged behind it, each with a pointed-conical shaped charge lining. The two shaped charges are ignited by a detonator with a slight time delay. In order to avoid that the detonation of the pre-shaped charge has a negative effect on the formation of the beam from the main shaped charge, a damping arrangement is provided between the pre-shaped charge and the main shaped charge. Peripheral components, such as a gyroscopic control system, an optical target acquisition sensor, an electrical supply unit and ignition and safety devices are also arranged around the central duct to protect the main charge in the circumferential area for free formation of the main charge charge and around the precharge itself.

Dieser Tandem-Gefechtskopf beinhaltet den funktionalen Nachteil, daß zwar die Rückwirkung der Vorhohlladungsdetonation auf die rückwärtige Haupthohlladung gemildert ist, da aber der gesamte Gefechtskopf sich bei Zündung der Vorhohlladung bereits unmittelbar vor dem Aktivmodul der Zielpanzerung befindet, wird der Haupthohlladungsstrahl in seiner Ausbildung und zerstörerischen Wirkung durch abgesprengte Teile, Gasschlag und Splitter der Aktivmodule erheblich beeinträchtigt.This tandem warhead has the functional disadvantage that the reaction of the precharge charge detonation to the rear main charge is alleviated, but since the entire warhead is already immediately in front of the active module of the target armor when the precharge is fired, the main charge charge beam develops and has a destructive effect significantly affected by blasted parts, gas hammer and splinters of the active modules.

In der EP-A-0 238 715 ist gleichfalls eine Tandem-Hohlladungsanordnung beschrieben, die zur zeitlich verzögerten Aufschlagszündung von Vorhohlladung und Haupthohlladung zwei voneinander völlig entkoppelte Aufschlagszündeinrichtungen einfacher Bauweise benötigt. Die zuvor geschilderten Nachteile gelten auch für diese Geschoßanordnung. Diese Druckschrift stellt ebenso einen Stand der Technik gemäß Artikel 54(3) EPÜ dar.EP-A-0 238 715 likewise describes a tandem shaped charge arrangement which, for the time-delayed impact ignition of pre-charge and main charge, requires two simple design impact ignition devices which are completely decoupled from one another. The disadvantages described above also apply to this floor arrangement. This document also represents prior art under Article 54 (3) EPC.

Aus der FR-A-23 10 547 ist eine Tandem-Hohlladungsanordnung bekannt, die eine durchmesserverkleinerte Vorhohlladung und eine dahinter angeordnete Haupthohlladung mit jeweils einer Spitzkegel-Hohlladungseinlage aufweist. Zur Einstellung des optimalen Abstandes (Stand-Off) der Haupthohlladung vom Ziel beim Auftreffen des Gefechtskopfes auf das Ziel kann ein aus der Gefechtskopfhaube hervorstehendes oder herausschiebbares Rohr vorgesehen werden, auf dessen vorderen Ende die Vorhohlladung angeordnet ist. Beim Auftreffen des Gefechtskopfes auf das Ziel wird zunächst die Vorhohlladung gezündet und anschließend die etwa im Abstand des Stand-Off befindliche Haupthohlladung. Da sich auch in diesem Fall der gesamte Gefechtskopf bei der Zündung der Vorhohlladung bereits unmittelbar vor dem Aktivmodul der Zielpanzerung befindet, wird die Strahlausbildung der Haupthohlladung durch die Rückwirkung von Gasschlag und abfliegenden splittern aus der Detonation der Vorhohlladung erheblich gestört.From FR-A-23 10 547 a tandem shaped charge arrangement is known, which has a reduced-diameter pre-shaped charge and a main shaped charge arranged behind it, each with a pointed cone shaped charge insert. To set the optimal distance (stand-off) of the main hollow charge from the target when the warhead hits the target, a tube protruding or sliding out of the warhead hood can be provided, on the front end of which the pre-hollow charge is arranged. When the warhead hits the target, the pre-charge is ignited and then the main charge, which is approximately at a distance from the stand-off. Since the entire warhead is already immediately in front of the active module of the target armor when the precharge is fired in this case, the beam formation of the main precharge is considerably disturbed by the reaction of gas hammer and flying splinters from the detonation of the precharge.

Die DE-A-28 39 002 offenbart einen Multi-Gefechtskopf mit mehreren Wirkteilen. Ein Vorwirkkörper mit einer oder mehrerer strahlbildender Hohlladungen wird hierbei mittels Trennladung vom Hauptwirkkörper mit Haupthohlladung abgetrennt und mittels eines Raketentriebwerkes gegen ein Ziel beschleunigt. Ein derartiger Multi-Gefechtskopf ist kompliziert, raum-und fertigungsaufwendig und umfaßt das Vorhandensein großer zielunwirksamer Lastenanteile.DE-A-28 39 002 discloses a multi-warhead with several active parts. A pre-active body with one or more beam-forming hollow charges is separated from the main active body with the main hollow charge by means of a separating charge and accelerated against a target by means of a rocket engine. A multi-warhead of this type is complicated, takes up a lot of space and is expensive to manufacture and comprises the presence of large, ineffective load components.

Weiterhin beschreibt die FR-A-999 974 Hohlladungsgeschosse, bei denen zwei oder drei kalibergroße strahlbildende Hohlladungen hintereinander angeordnet sind. Diese Hohlladungen sollen mittels Aufschlagzünder gezündet werden und durch zwei oder drei Strahlen eine größere Eindringtiefe in Panzerungen eines Zieles ergeben. Bei gleichzeitiger Initiierung der Hohlladungen wird jedoch jeweils die hintere Hohlladung durch die Detonation dervorgelagerten Hohlladung erheblich gestört; gegen mitAktivmodulen geschützte Ziele ist eine derartige Hohlladungsgeschoßanordnung nahezu wirkungslos.Furthermore, FR-A-999 974 describes shaped charge bullets in which two or three caliber-sized beam-forming shaped charges are arranged one behind the other. These shaped charges should be detonated by means of impact detonators and should result in a greater depth of penetration into the armor of a target through two or three beams. If the shaped charges are initiated at the same time, however, the rear shaped charge is considerably disturbed by the detonation of the preceding shaped charge; such a shaped charge storey arrangement is virtually ineffective against targets protected with active modules.

Ein anderer Wirkkörper in Tandemausführung ist aus der DE-A-34 16 787 bekannt. Die beiden Ladungen sind im wesentlichen einander durchmessergleich und jede von ihnen ist in einem jeweiligen Gehäuse mit Stabilisierungsflügeln angeordnet und bildet nach dem Initiieren einer gesonderten Trennladung jeweils ein selbständiges Projektil. Diese bekannte Anordnung ist nicht nur kompliziert und sehr raum- sowie fertigungsaufwendig, sondern erzwingt auch das Vorhandensein großer zielunwirksamer Lastenanteile (Totlast), die bei jeder Einsatzart sehr nachteilig ins Gewicht fallen.Another active body in tandem is known from DE-A-34 16 787. The two charges are essentially of the same diameter and each of them is arranged in a respective housing with stabilizing wings and forms an independent projectile after the initiation of a separate separating charge. This known arrangement is not only complicated and takes up a lot of space and production, but also forces the presence of large, ineffective load components (dead load), which are very disadvantageous for each type of application.

Aus der FR-AL-2,552,870 ist schließlich ein Gefechtskopf mit zwei hintereinander angeordneten Wirkladungen bekannt, wobei die vordere Wirkladung eine projektilbildende Einlage besitzt und zum zielseitigen Verbrauchen einer vor der Hauptpanzerung des Zieles angeordneten Störeinrichtung vorgesehen ist, und die hintere Hauptladung zum Durchschlagen der Hauptpanzerung als Hohlladung ausgebildet ist. Vordere Wirkladung und Hauptladung sind etwa kalibergleich ausgebildet und sind durch eine Dämpfungsanordnung voneinander getrennt. Nachteilig bei diesem bekannten Gefechtskopf ist vor allem, daß durch die Dämpfungsanordnung der Hohlladungsstrahl der Hauptladung gestört wird, so daß es unter Umständen nicht zu dem gewünschten Durchschlagen der Hauptpanzerung kommt. Außerdem Finally, from FR-AL-2,552,870 a warhead with two active charges arranged one behind the other is known, the front active charge having a projectile-forming insert and intended for the targeted use of an interfering device arranged in front of the main armor of the target, and the rear main charge for penetrating through the main armor as Hollow charge is formed. The front active charge and main charge are of approximately the same caliber and are separated from one another by a damping arrangement. A disadvantage of this known warhead is that the hollow charge jet of the main charge is disturbed by the damping arrangement, so that the desired penetration of the main armor may not occur. Furthermore

kann es bei Detonation der relativ großen vorderen Wirkladung leicht zu Beschädigung der Hauptladung kommen. Schließlich ist die gesamte Ladungsanordnung relativ platzaufwendig.Detonation of the relatively large front active charge can easily damage the main charge. Finally, the entire charge arrangement is relatively space-consuming.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Gefechtskopf der eingangs genannten Gattung anzugeben, der die zuvor geschilderten Nachteile beseitigt und der sich raumsparend und mit geringem Totlastanteil vielseitig einsetzen läßt. Eine störende Auswirkung von zielseitig abgesprengten Bauteilen und Splittern des zu beseitigenden Aktivmoduls auf die Ausbildung des Hohlladungsstrahles der Haupthohlladung soll vermieden werden. Gelöst wird diese Aufgabe nach der Lehre des Patentanspruches 1 mit den darin angegebenen erfinderischen Merkmalen.It is therefore an object of the present invention to provide a warhead of the type mentioned at the outset which eliminates the disadvantages described above and which can be used in a versatile manner in a space-saving manner and with a low dead load component. A disruptive effect of components blasted off at the target and splinters of the active module to be removed on the formation of the shaped charge jet of the main shaped charge should be avoided. This object is achieved according to the teaching of claim 1 with the inventive features specified therein.

Dadurch, daß die vordere Wirkladung mit einer projektilbildenden flachen Einlage versehen ist und von einem an sich bekannten Annäherungszünder in vorgebbarer Entfernung vor dem Aktivziel gezündet wird, wird erreicht, daß aus der flachen Einlage ein Projektil gebildet wird und der Haupthohlladung gegen das Ziel vorauseilt und dort das Aktivmodul für eine ungestörte Wirkung des nachfolgenden Haupthohlladungsstrahles unschädlich macht. Die erfindungsgemäße Tandem-Gefechtskopfanordnung ist raumsparend und mit geringem Totlastanteil ausgebildet.The fact that the front active charge is provided with a projectile-forming flat insert and is ignited by a known proximity fuse at a predeterminable distance in front of the active target means that a projectile is formed from the flat insert and leads the main hollow charge against the target and there makes the active module harmless for an undisturbed effect of the subsequent main hollow charge beam. The tandem warhead arrangement according to the invention is space-saving and designed with a low dead load component.

Die Erfindung wird nachstehend anhand der in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert und beschrieben. Es zeigen:

wobei in den Figuren 2, 3 und 4 aus Gründen besserer Übersichtlichkeit auf eine in Einzelheiten gehende Darstellung der Erfindung mit Rücksicht auf Fig. 1 verzichtet werden kann.in FIGS. 2, 3 and 4, for reasons of better clarity, it is possible to dispense with a detailed illustration of the invention with regard to FIG. 1.

Gemäß Fig. 1 weist ein Wirkkörper 10 nach der Erfindung eine zur Längsachse A rotationssymmetrische Hülle 11 mit einer Ladung 12 auf. Ein Anschlußmittel 13 dient als Aufnahme für Einrichtungen 22 zur Stromversorgung für eine Steuerelektronik 24. Ein Rohr 15 definiert einen Akoaxialen Kanal 16 füreinen nach dem initiieren der Ladung 12 aus einer Einlag 14 zu bildenden Hohlladungsstrahl. Das Rohr 15 dient mit einem vorderen Bereich des Kanals 16 einer Ladung 18 mit einer Hülle 19 und einer flachen projektilbildenden Einlage 20 als Aufnahme.1, an active body 10 according to the invention has a casing 11 with a charge 12 that is rotationally symmetrical with respect to the longitudinal axis A. A connection means 13 serves as a receptacle for devices 22 for the power supply for control electronics 24. A tube 15 defines an acoaxial channel 16 for a shaped charge beam to be formed from an insert 14 after the charge 12 has been initiated. The tube 15 serves as a receptacle with a front region of the channel 16 of a charge 18 with a casing 19 and a flat projectile-forming insert 20.

Der Wirkkörper 10 eignet sich auf besonders vorteilhafte Weise zum Bekämpfen, insbesondere aktiv, gepanzerter Ziele. Ein nicht dargestellter und an sich bekannter Annäherungszünder gibt in vorgebbarer Entfernung vor einem Ziel ein Signal an die Steuerelektronik 24. Aus dem Signal wird ein erstes Steuersignal zum Initiieren der vorderen Ladung 18 gebildet, und ein Projektil aus der flachen Einlage 20 eilt dem Wirkkörper 10 voraus gegen das Ziel. Dort wird durch das Auftreffen des Projektils eine bekannte Störeinrichtung zur Wirkung gebracht und damit für einem Hohlladungsstrahl unschädlich gemacht, welcher aus der Einlage 14 der durch ein zweites Steuersignal initiierten, hinteren Ladung 12 gebildet wird. Der zielseitige "Entstöreffekt" wird dabei mit raumsparenden Mitteln, mit geringstmöglichem Totlastanteil und ohne eine die Störanfälligkeit des Wirkkörpers erhöhende und ihn komplizierende, aus der eingangs zitierten Druckschrift bekannte Trennladung erzielt.The active body 10 is particularly advantageously suitable for combating, in particular actively, armored targets. A proximity fuse, which is not shown and is known per se, gives a signal to the control electronics 24 at a predeterminable distance from a target. The signal forms a first control signal for initiating the front charge 18, and a projectile from the flat insert 20 leads the active body 10 against the target. There, a known interfering device is brought into effect by the impact of the projectile and thus rendered harmless for a shaped charge jet which is formed from the insert 14 of the rear charge 12 initiated by a second control signal. The target-side "interference suppression effect" is achieved with space-saving means, with the lowest possible dead load component and without a separation charge which increases and complicates the susceptibility of the active body and complicates it, which is known from the publication cited at the beginning.

Die flache Einlage 20 der vorderen Ladung 18 besteht vorzugsweise aus einem Werkstoff mit der durchschnittlichen Dichte zwischen etwa 16 und etwa 19 g/cm3. Hierdurch wird infolge entsprechend hoher Wuchtwirkung des aus der Einlage 30 sprengumgeformten Projektils eine zielseitige Störeinrichtung mit hoher Wahrscheinlichkeit unschädlich gemacht, so daß der Hohlladungsstrahl aus der Einlage 14 voll zielwirksam werden kann. Dabei läßt sich ein günstigster Stand-off einhalten. Wegen der vergleichsweisen Kleinheit der Einlage 20 brauchtvorteilhafterweise der Preis für den Einlagenwerkstoff keine so wesentliche Rolle zu spielen, so daß beispielsweise auch der Verwendung von Tantal kein Kostenhindernis im Wege steht.The flat insert 20 of the front load 18 is preferably made of a material with an average density between approximately 16 and approximately 19 g / cm 3 . As a result, due to the correspondingly high balancing effect of the projectile explosively formed from the insert 30, a target-side interfering device is made harmless with a high probability, so that the shaped charge jet from the insert 14 can become fully effective. A cheapest stand-off can be observed. Because of the comparatively small size of the insert 20, the price for the insert material advantageously does not have to play such an important role, so that, for example, the use of tantalum does not hinder the cost.

Beim Betrachten der Figuren 2, und 4 derZeichnung wird im Zusammenhang mit der vorstehenden Beschreibung erkennbar, wie vielseitig einsetzbar der Wirkkörper 10 nach der Erfindung ist.When viewing FIGS. 2 and 4 of the drawing, it can be seen in connection with the above description how versatile the active body 10 according to the invention is.

Nach Figur 2 ist der Wirkkörper 10 einem Gefechtskopf40 eingefügt, welcher als lenkbare Submunitionseinheit aus einem Lastengeschoß ausstoßbar ist. In diesem Zusammenhang wird auf ein Prospektblatt der Firmen Allied Bendix Aerospace und Rheinmetall GmbH (Anmelder) verwiesen, welcher seit Oktober 1985 veröffentlicht ist. Das Anschlußmittel 13' erstreckt sich bis zu einem an sich bekannten Zielsuchkopf 52 und dient einer Elektronik 44 und einem Steuerblock 46 mit Gasgeneratoren 48 und Steuerdüsen 50 als Aufnahme, wobei sich die vorgenannten Einrichtungen hinter dem Zielsuchkopf 52 um das Rohr 15 mit dem Kanal 16 herum raumsparend gruppieren. Stabilisierungsflügel 42 sind auf bekannte Weise aus einer raumsparenden Transportstellung in ihre dargestellte Wirkstellung schwenkbar. Die Flugrichtung des Gefechtskopfs 40 mit dem Wirkkörper 10 ist durch einen Pfeil F angedeutet.According to FIG. 2, the active body 10 is inserted into a warhead 40, which can be ejected from a cargo floor as a steerable submunition unit. In this context, reference is made to a brochure by Allied Bendix Aerospace and Rheinmetall GmbH (applicant), which has been published since October 1985. The connection means 13 'extends to a known seeker 52 and serves as electronics 44 and a control block 46 with gas generators 48 and control nozzles 50, the aforementioned devices behind the seeker 52 around the pipe 15 with the channel 16 group space-saving. Stabilizing wings 42 can be pivoted in a known manner from a space-saving transport position into the operative position shown. The direction of flight of the warhead 40 with the active body 10 is indicated by an arrow F.

Nach Figur 3 ist der Wirkkörper 10, geringfügig modifiziert, (verwiesen wird u.a. auf die Gestalt der Einlage 64) einer Panzerabwehrrichtmine 60 integriert. Sie weist ein Abschußrohr 62 auf einer Dreibeinlafette 74 auf. Die nicht dargestellte zentrale Längsachse einer bekannten Zieleinrichtung 66 mit der erforderlichen Steuerelektronik verläuft der Längsachse A parallel. Ein Raketenmotor 70 ist über eine Anzündeinrichtung 68 initiierbar. Das Abschußrohr 62 wird mittels der Lafette 74 so aufgestellt, daß seine Längsachse auf einen Bereich gerichtet ist, in welchem zu bekämpfende gepanzerte Ziele erwartet werden. Hat die Zieleinrichtung 66 ein solches Ziel identifiziert, wird über ein Signal die Anzündeinrichtung 68 initiiert und von ihr der Raketenmotor 70 gezündet. Der Wirkkörper 10 verläßt das Rohr 62 nach Wegsprengen dessen Deckels 76 in Richtung eines Pfeils F, und Stabilisierungsflügel 72 klappen aus ihrer in der Zeichnung dargestellten Ruhestellung in ihre Wirkstellung aus. Wegen der Funktionsabfolge wird auf die Beschreibung im Zusammenhand mit Figur 1 verwiesen.According to FIG. 3, the active body 10, slightly modified, (reference is made, inter alia, to the shape of the insert 64) of an anti-tank mine 60. It has a launch tube 62 on a three leg mount 74 on. The central longitudinal axis (not shown) of a known target device 66 with the required control electronics runs parallel to the longitudinal axis A. A rocket engine 70 can be initiated via an ignition device 68. The launch tube 62 is positioned by means of the mount 74 so that its longitudinal axis is directed to an area in which armored targets to be combated are expected. If the target device 66 has identified such a target, the ignition device 68 is initiated via a signal and the rocket motor 70 is ignited by it. The active body 10 leaves the tube 62 after the cover 76 has blown away in the direction of an arrow F, and the stabilizing wings 72 fold out of their rest position shown in the drawing into their active position. Because of the sequence of functions, reference is made to the description in conjunction with FIG. 1.

In Figur 4 ist ein Panzerabwehrgeschoß 80 einer bekannten Munition für eine Kanone dargestellt. Mit Ausnahme einer Spitzkegeleinlage 84 der hinteren Ladung 12 ist auf eine Darstellung von Einzelheiten des integrierten Wirkkörpers 10 verzichtet. Das Rohr 15 istals Standoff-Rohr 82 ausgebildet und trägt vorderseitig einen bekannten und deshalb nicht näher dargestellten und zu beschreibenden Annäherungsünder 86. An einem Leitwerkschaft 88 ist ein bekanntes feststehendes Stabilisierungsleitwerk 90 angeordnet.FIG. 4 shows an anti-tank projectile 80 of a known ammunition for a cannon. With the exception of a pointed cone insert 84 of the rear cargo 12, details of the integrated active body 10 are not shown. The tube 15 is designed as a standoff tube 82 and carries on the front side a known approach nozzle 86, which is therefore not shown or described in detail. A known stabilizing stabilizer 90 is arranged on a tail boom 88.
