Description

Die Neuerung betrifft ein Hohlladungstochtergeschoß nach dem Oberbegriff des Anspruchs 1.The innovation relates to a shaped charge daughter storey according to the preamble of claim 1.

Ein Hohlladungstochtergeschoß der gattungsgemäßen Art ist aus der DE-OS 22 42 930 bekannt. Bei dem bekannten Hohlladungstochtergeschoß besteht der Geschoßkörper aus einem topfförmigen Teil, das vermittels Fließpressen aus einem Drahtabschnitt hergestellt ist. Das Fließpressenfahren ist ein vergleichsweise aufwendiger Herstellungsprozeß, der die Herstellungskosten des Hohlladungstochtergeschosses verteuert. Zudem verhindert die durch das Fließpressen erzeugbare topfförmige Gestalt des Geschoßkörpers eine verfahrensmäßig einfach und daher wiederum kostengünstige Bearbeitung des Geschoßkörpermantels zur Erzeugung einer splitterbegünstigenden Struktur des Geschoßkörpers.A shaped charge daughter storey of the generic type is known from DE-OS 22 42 930. In the known shaped charge daughter projectile, the projectile body consists of a cup-shaped part, which is produced by means of extrusion from a wire section. Extrusion driving is a comparatively complex manufacturing process, which increases the manufacturing costs of the shaped charge subsidiary storey. In addition, the cup-shaped shape of the projectile body, which can be produced by the extrusion, prevents a procedurally simple and therefore, in turn, inexpensive processing of the projectile body shell to produce a structure of the projectile body which promotes splintering.

Der Neuerung liegt die Aufgabe zugrunde, ein Hohlladungstochtergeschoß der eingangs näher bezeichneten Art dahingehend zu verbessern, daß eine einfachere und preiswertere Herstellung ermöglicht wird.The innovation is based on the object of improving a shaped charge daughter storey of the type specified at the outset in such a way that simpler and cheaper production is made possible.

Diese Aufgabe wird durch die in Schutzanspruch angegebene Neuerung gelöst.This task is solved by the innovation specified in the protection claim.

Die Anfertigung des Geschoßkörpers aus einem längsnahtgeschweißten, nahtlos gezogenen bzw. wendelförmig gewickelten Rohr verringert die Herstellungskosten beträchtlich. Da das Flachmaterial während des Fertigungsprozesses von zwei Seiten zugänglich ist, können auf einfache Weise durch einen Walzvorgang auch Strukturierungen in den Rohrmantel eingebracht werden, die die Splitterbildung begünstigen. Schließlich kann auch noch die Sprengladung des Hohlladungstochtergeschosses von beiden Seiten in den Geschoßkörper eingepreßt werden.The manufacture of the projectile body from a longitudinally welded, seamlessly drawn or helically wound tube reduces the manufacturing costs considerably. Since the flat material is accessible from two sides during the manufacturing process, structuring that promotes the formation of splinters can also be introduced into the tube jacket in a simple manner by means of a rolling process. Finally, the explosive charge of the shaped charge daughter projectile can be pressed into the projectile body from both sides.

Die Neuerung wird unter Bezug auf die Zeichnung weiter erläutert. Dabei Zeigt:

  • Fig. 1: einen Längsschnitt durch das Hohlladungstochtergeschoß;
  • Fig. 2: eine Seitenansicht des Hohlladungstochtergeschosses.
The innovation is explained further with reference to the drawing. It shows:
  • Fig. 1: a longitudinal section through the shaped charge daughter floor;
  • 2: a side view of the shaped charge daughter story.

Fig. 1 zeigt im Längsschnitt ein Hohlladungstochtergeschoß 10, das in großer Stückzahl von einem Laatengeschoß über ein Zielgebiet transportiert und dort ausgestoßen wird. Es besteht aus einem Geschoßkörper 12 und einem damit verbundenen Zünderkörper 11. Der Geschoßkbrper seinerseits besteht aus einer Hülle 13 und einer darin angeordneten Hohlladung 14 mit Einlage 15. Gemäß der Neuerung besteht die Hülle 13 des Geschoßkörpers 12 aus einem beidseitig offenen Rohrabschnitt, in das der Zünderkörper 11 einseitig mittels eines Gewindes 16 eingeschraubt ist.Fig. 1 shows in longitudinal section a shaped charge daughter storey 10, which is transported in large numbers from a state storey over a target area and is ejected there. It consists of a projectile body 12 and a detonator body 11 connected thereto. The projectile body in turn consists of a casing 13 and a hollow charge 14 arranged therein with insert 15. According to the innovation, the casing 13 of the projectile body 12 consists of a tube section open on both sides, into which the Detonator body 11 is screwed in on one side by means of a thread 16.

Die Hülle 13 kann zweckmäßig ein Abschnitt geeigneter Länge eines nahtlos gezogenen Rohrs oder eines wendelgegewickelten oder längsnahtgeschweißten Rohrs sein.The sleeve 13 may suitably be a section of suitable length of a seamless drawn tube or a helically wound or longitudinally welded tube.

Da die Hülle 31 zu Anfang des Herstellungsverfahrens beidseitig offen ist, kann zumindest eine Mantelfläche der Hülle 13, im Bedarfsfall aber auch jede Mantelfläche, durch einen relativ einfachen und preiswerten Walzvorgang noch so strukturiert werden, daß sich willkürlich hergestellte Schwächungszonen ergeben, die eine gezielte Splitterbildung ermöglichen. In die Hülle 13 wird im Verlauf des weiteren Herstellungsverfahrens des Hohlladungstochtergeschosses 10 der Sprengstoff der Hohlladung 14 eingebracht. Da es sich hierbei in der Regel um eine gepreßte Ladung handelt, kann zunächst der Zünderkörper 11 in die Hülle 13 eingeschraubt werden. Die Hohlladung 14 wird dann nach Einfüllen des Sprengstoffs von der offenen Seite der Hülle 13 einseitig in die Hülle 13 gepreßt. Die Ausgestaltung der Hülle 13 als beidseitig offenes Rohr ermöglicht es jedoch auch, die Hohlladung 14 von beiden Stirnflächen der Hülle 13 her zu pressen, so daß sich besonders dicht gepackte Ladungsaufbauten ergeben. In diesem Fall wird der Zünderkörper 11 erst nach dem Preßvorgang in die Hülle 13 eingeschraubt.Since the casing 31 is open on both sides at the beginning of the manufacturing process, at least one casing surface of the casing 13, but if necessary also each casing surface, can be structured by a relatively simple and inexpensive rolling process in such a way that arbitrarily produced weakening zones result, which form targeted fragments enable. The explosive of the shaped charge 14 is introduced into the casing 13 in the course of the further manufacturing process of the shaped charge daughter storey 10. Since this is generally a pressed charge, the igniter body 11 can first be screwed into the casing 13. The shaped charge 14 is then pressed into the shell 13 on one side after the explosive has been filled in from the open side of the shell 13. The design of the sleeve 13 as a tube open on both sides also makes it possible to press the shaped charge 14 from both end faces of the sleeve 13, so that particularly densely packed charge structures result. In this case, the igniter body 11 is screwed into the casing 13 only after the pressing process.

Um dabei u. U. auftretende Spalte zwischen der Oberfläche der Hohlladung 14 und dem Zünderkörper 11 zu verhindern, die die Wirksamkeit der Hohlladung 14 beeinträchtigen, kann eine Klebstoffschicht zwischen dem Zünderkörper und der Oberfläche der Hohlladung 14 angeordnet werden.To u. To prevent gaps occurring between the surface of the shaped charge 14 and the igniter body 11, which impair the effectiveness of the shaped charge 14, an adhesive layer can be arranged between the igniter body and the surface of the shaped charge 14.

In der Seitenansicht des Hohlladungstochtergeschosses 10 nach Fig. 2 ist mit 20 die Längsnaht eines längsnahtverschweißten, als Hülle 13 verwendeten Rohrstücks angedeutet, während die punktierten Linien 21 auf die Verwendung eines wendelförmig gewickelten Rohrs hindeuten.In the side view of the shaped charge daughter projectile 10 according to FIG. 2, the longitudinal seam of a longitudinally welded tube piece used as a casing 13 is indicated by 20, while the dotted lines 21 indicate the use of a helically wound tube.
