In order not to impair the function of the active charge 12, at most the antenna 16 of the target recognition device 15 is arranged in the flight direction in front of the active charge 12, while the target recognition device 15 has its place in the flight direction behind the active charge 12. A waveguide 17, 17 'filled with explosive is provided to connect the antenna 16 to the target recognition device 15.

Description

Die Erfindung betrifft einen Geschoßkopf nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a projectile head according to the preamble of claim 1.

Geschoßköpfe der gattungsgemäßen Art sind aus der DE-OS 21 36 788 bekannt. Sie werden über einem Zielgebiet von einem Lastengeschoß oder einem Flugkörper abgeworfen und sinken dort von einem aerodynamischen Bremsmittel, z. B. einem Fallschirm, gebremst nieder, wobei sie ein Ziel autonom erfassen und es nach Erreichen der Bekämpfungsreichweite bekämpfen. Sie verfügen dazu über eine von einem Zielortungssignal zündbare Wirkladung. Dieses Zielortungssignal wird von einem im Geschoßkopf angeordneten Sendeempfänger geliefert, der ein im Mikrowellenbereich liegendes Hochfrequenzsignal über eine Antenne abstrahlt und das vom Ziel reflektierte Signal wieder empfängt. Um die Funktion der Wirkladung möglichst wenig zu beeinträchtigen, ist es aus der vorgenannten Entgegenhaltung bereits bekannt, das den SendeEmpfänger umfassende Zielerkennungsgerät in Flugrichtung hinter der Wirkladung und lediglich die Antenne des Zielerkennungsgeräts in Flugrichtung vor der Wirkladung anzuordnen. Über die Art der Verbindung zwischen der Antenne des Zielerkennungsgeräts und dem Zielerkennungsgerät sind in der genannten DE-OS keine Angaben gemacht.Projectile heads of the generic type are known from DE-OS 21 36 788. They are dropped from a cargo floor or a missile over a target area and sink there by an aerodynamic braking means, e.g. B. a parachute, braked down, autonomously detecting a target and fighting it after reaching the combat range. For this purpose, they have an active charge that can be ignited by a destination signal. This target location signal is supplied by a transceiver arranged in the projectile head, which transmits a high-frequency signal in the microwave range via an antenna and receives the signal reflected by the target again. In order to impair the function of the active charge as little as possible, it is already known from the abovementioned citation to arrange the target recognition device comprising the transceiver in the flight direction behind the active charge and only the antenna of the target recognition device in the flight direction before the active charge. No information is given in the DE-OS mentioned about the type of connection between the antenna of the target recognition device and the target recognition device.

Der Erfindung liegt die Aufgabe zugrunde, einen Geschoßkopf der eingangs genannten Art dahingehend auszugestalten, daß die Funktion der Wirkladung möglichst wenig beeinträchtigt istThe invention has for its object to design a projectile head of the type mentioned in such a way that the function of the active charge is affected as little as possible

Diese Aufgabe wird durch die in Patentanspruch 1 angegebene Erfindung gelöst. Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.This object is achieved by the invention specified in claim 1. Advantageous embodiments of the invention emerge from the subclaims.

Die Erfindung wird nachfolgend unter Bezug auf die Zeichnung näher erläutert. Dabei zeigt:

  • Fig. 1: in schematischer Darstellung teilweise im Schnitt einen an einem Fallschirm niedersinkenden Gefechtskopf;
  • Fig. 2: einen Querschnitt entlang der Linie 2-2 nach Fig. 1;
  • Fig. 3: zur Erläuterung eines weiteren Ausführungsbeispiels der Erfindung eine vergrößerte Detaildarstellung der Fig. 2.
The invention is explained in more detail below with reference to the drawing. It shows:
  • 1: a schematic representation, partly in section, of a warhead sinking down on a parachute;
  • 2 shows a cross section along the line 2-2 of Fig. 1.
  • 3: to explain a further exemplary embodiment of the invention, an enlarged detailed illustration of FIG. 2.

Fig. 1 zeigt in schematischer Darstellung einen Gefechtskopf 10, der von einem aerodynamischen Bremsmittel, vorzugsweise einem Fallschirm 14, gebremst über einem Zielgebiet niedersinkt, nachdem er von einem Lastengeschoß oder einem Flugkörper über dieses Zielgebiet transportiert worden ist. Der Gefechtskopf 10 umfaßt in einer Hülle 11 eine Wirkladung 12. Diese Wirkladung kann aus einer sogenannten projektilbildenden oder einer Hohlladung bestehen. Der Gefechtskopf 10 ist in der Lage, nach Abwurf ein Ziel autonom zu bekämpfen.Fig. 1 shows a schematic representation of a warhead 10 which, when braked by an aerodynamic braking means, preferably a parachute 14, descends over a target area after it has been transported by a cargo floor or a missile over this target area. The warhead 10 comprises an active charge 12 in a shell 11. This active charge can consist of a so-called projectile-forming or a shaped charge. The warhead 10 is able to autonomously combat a target after being dropped.

Dazu verfügt er über ein Zielerkennungsgerät 15, das in einem ersten Ausführungsbeispiel einen im Mikrowellenbereich arbeitenden Sender und einen Empfänger umfaßt. Die vom Sender erzeugte Hochfrequenzenergie wird von einer Antenne 16 abgestrahlt, die von einem Ziel reflektierte Strahlung wird von der gleichen Antenne 16 empfangen und dem Empfänger im Zielerkennungsgerät 15 zur Auswertung zugeführt. In einem weiteren Ausführungsbeispiel der Erfindung arbeitet das Zielerkennungsgerät 15 lediglich passiv als Radiometer, das vermittels der Antenne 16 von einem Ziel ausgehende Strahlung aufnimmt. Um die Effektivität der Wirkladung 12 nicht nachteilig zu beeinflussen, wird höchstens die Antenne 16 des Zielerkennungsgeräts 15 in Flugrichtung vor der Wirkladung 12 angeordnet, während das Zielerkennungsgerät 15 selbst in Flugrichtung hinter der Wirkladung 12 angebracht ist. Wenn nun - was im Mikrowellenbereich an sich bekannt ist - Antenne 16 und Zielerkennungsgerät 15 lediglich durch einen üblichen Hohlleiter oder Wellenleiter verbunden würden, könnte eine Verringerung der Wirksamkeit der Wirkladung 12 nicht ausgeschlossen werden, da der wirksame Querschnitt der Wirkladung 12 durch den Wellenleiter verringert ist. Um diesen Nachteil zu . verhindern, wird erfindungsgemäß die Verbindung zwischen der Antenne 16 und dem Zielerkenungsgerät 15 des Gefechtskopfes 10 als sprengstoffgefüllter Wellenleiter 17, 17' ausgeführt. Zweckmäßig besteht der Wellenleiter 17, 17' dabei aus einem Metallrohr 17", das mit Sprengstoff 17 ausgefüllt ist. Die Abmessungen des Metallrohrs 17' sind dabei in an sich bekannter Weise so zu wählen, daß die Mikrowellenenergie zwischen Antenne 16 und Zielerkennungsgerät 15 weitergeleitet werden kann.For this purpose, it has a target recognition device 15 which, in a first exemplary embodiment, comprises a transmitter operating in the microwave range and a receiver. The radio frequency energy generated by the transmitter is emitted by an antenna 16, the radiation reflected by a target is received by the same antenna 16 and fed to the receiver in the target recognition device 15 for evaluation. In a further exemplary embodiment of the invention, the target recognition device 15 only works passively as a radiometer, which uses the antenna 16 to receive radiation emanating from a target. In order not to adversely affect the effectiveness of the active charge 12, at most the antenna 16 of the target recognition device 15 is arranged in front of the active charge 12 in the direction of flight, while the target recognition device 15 itself is mounted behind the active charge 12 in the direction of flight. If - as is known per se in the microwave range - antenna 16 and target recognition device 15 were only connected by a conventional waveguide or waveguide, a reduction in the effectiveness of the active charge 12 could not be ruled out, since the effective cross section of the active charge 12 through the waveguide is reduced . To overcome this disadvantage. prevent, according to the invention the connection between the antenna 16 and the target detection device 15 of the warhead 10 is designed as an explosive-filled waveguide 17, 17 '. The waveguide 17, 17 'expediently consists of a metal tube 17 ″ which is filled with explosive 17. The dimensions of the metal tube 17' are to be selected in a manner known per se such that the microwave energy is passed on between the antenna 16 and the target recognition device 15 can.

In einer besonders vorteilhaften Ausführungsform der Erfindung (Fig. 3) wird der Wellenleiter 17 dadurch gebildet, daß die Mantelfläche eines Zylinders 37 aus Sprengstoff mit einer metallischen Schicht 37' bedampft wird.In a particularly advantageous embodiment of the invention (FIG. 3), the waveguide 17 is formed in that the outer surface of a cylinder 37 made of explosive is vapor-coated with a metallic layer 37 '.

Diese metallische Schicht 37' kann beispielsweise aus Aluminium oder Kupfer bestehen. Während dieser Wellenleiter einerseits gut geeignet ist zur Fortleitung von Hochfrequenzenergie zwischen dem Zielerkennungsgerät 15 und der Antenne 16, beeinträchtigt andererseits die vergleichsweise geringe Metallmenge der dünnen metallischen Schicht 37' die Funktion der Wirkladung 12 nicht. Der metallisierte Sprengstoffzylinder 37 wird zweckmäßig in einer Bohrung angeordnet, die zentrisch in der Wirkladung 12 vorgesehen ist.This metallic layer 37 'can consist, for example, of aluminum or copper. While this waveguide is well suited for transmitting high-frequency energy between the target recognition device 15 and the antenna 16, the comparatively small amount of metal in the thin metallic layer 37 'does not impair the function of the active charge 12. The metallized explosive cylinder 37 is expediently arranged in a bore which is provided centrally in the active charge 12.
