Description

Die Neuerung betrifft einen Gefechtskopf nach dem Oberbegriff des Schutzanspruchs 1.The innovation concerns a warhead according to the preamble of protection claim 1.

Ein derartiger Gefechtskopf ist aus der DE-05 22 42 930 bekannt. Der bekannte Gefechtskopf umfaßt ein Gefechtskopfgehäuse zur Aufnahme einer Hohlladung sowie einen mit dem Gefechtskopfgehäuse verbundenen Zünder. Der Gefechtskopf wird in einer größeren Anzahl von einem Flugkörper oder Lastengeschoß über ein Zielgebiet transportiert und dort ausgestoßen, um gebremst oder ungebremst auf das Zielgebiet hinabzusinken. Zwecks Stabilisierung seines Sinkflugs verfügt der bekannte Gefechtskopf über ein Leitwerk, das aus mehreren flexiblen, um den Gefechtskopf wickelbaren Flügeln besteht.Such a warhead is known from DE-05 22 42 930. The known warhead comprises a warhead housing for receiving a shaped charge and an igniter connected to the warhead housing. The warhead is transported in large numbers by a missile or cargo floor over a target area and is ejected there in order to sink braked or unbraked down to the target area. In order to stabilize its descent, the well-known warhead has an empennage which consists of several flexible wings that can be wrapped around the warhead.

Der Neuerung liegt die Aufgabe zugrunde,den bekannten Gefechtskopf hinsichtlich seines Leitwerks dahingehend zu verbessern, daß dieses Leitwerk trotz einer hohen Abschußfestigkeit einen geringeren Platz einnimmt.The innovation is based on the task of improving the known warhead with respect to its tail so that this tail takes up less space despite a high launch resistance.

Diese Aufgabe wird durch die in Schutzanspruch 1 angegebene Neuerung gelöst. Vorteilhafte Ausgestaltungen der Neuerung gehen aus den Unteransprüchen hervor.This object is achieved by the innovation specified in protection claim 1. Advantageous refinements of the innovation emerge from the subclaims.

Die Neuerung wird nachfolgend, unter Bezug auf die Zeichnung, näher erläutert. Dabei zeigt

  • Fig. 1: einen teilweise im Längsschnitt dargestellten Gefechtskopf;
  • Fig. 2: eine Aufsicht auf den Gefechtskopf aus Richtung des Pfeile A, wobei die Flügel im entfalteten Zustand gezeigt sind;
  • Fig. 3: eine Aufsicht auf die Flügel im eingeklappten Zustand.
The innovation is explained in more detail below with reference to the drawing. It shows
  • 1: a warhead partially shown in longitudinal section;
  • 2 shows a plan view of the warhead from the direction of arrows A, the wings being shown in the unfolded state;
  • Fig. 3: a top view of the wing in the folded state.

Fig. 1 zeigt,teilweise in Längsschnittdarstellung,einen Gefechtskopf 10, der ein Gefechtskopfgehäuse 11 zur Aufnahme einer eine Auskleidung 15 aufweisenden Hohlladung 14 und einen mit dem Gefechtskopfgehäuse 11 verbundenen Zünder 12 umfaßt. Zur Stabilisierung des Sinkflugs des Gefechtskopfes 10,nach dessen Ausstoßen aus dem Flugkörper oder Lastengeschoß,ist ein Leitwerk 14 vorgesehen. Das Leitwerk 14 umfaßt Flügelsegmente 14 a, 14 b, 14 c, die sich aneinandergelegt, vorzugsweise zu einer Kreisfläche ergänzen (Fig. 3) und die auf im Zünder 12 senkrecht angeordneten Achsen (20 a, 20 b, 20 c) in einer senkrecht zur Längsachse des Gefechtskopfes liegenden Ebene drehbar gelagert sind. Fig. 3 zeigt eine Aufsicht lediglich auf die Segmente 14 a, 14 b, 14 c, des Leitwerks 14, wobei die Segmente zusammengeklappt sind. Drehung in Richtung der Pfeile 30 um die Achsen 20 a, 20 b, 20 c führt zu dem in Fig. 2 dargestellten Zustand, bei dem die Segmente 14 a, 14 b, 14 c des Leitwerks 14 ausgeklappt sind und dabei über den Umfang des Gefechtskopfgehäuses 11 hinausragen. Da sich die Segmente 14 a, 14 b, 14 c des Leitwerks 14 in zusammengeklapptem Zustand (Fig. 3) ganzflächig auf der Stirnfläche des Zünders 12 abstützen, sind sie in der Lage sehr große Beschleunigungskräfte in Längsaxialrichtung des Gefechtskopfes 10 aufzunehmen, obgleich sie lediglich aus einem relativ dünnen flexiblen Material, wie beispielsweise Federstahl bestehen. Im ausgeklappten Zustand (Fig. 2) stabilisieren sie die Lage des Gefechtskopfes 10 derart, daß er mit der Öffnungfläche der Hohlladung 14 auf die Zieloberfläche auftrifft, wobei sie gleichzeitig die Sinkgeschwindigkeit des Gefechtskopfes in erwünschter Weise reduzieren.1 shows, partially in longitudinal section, a warhead 10 which comprises a warhead housing 11 for receiving a hollow charge 14 having a lining 15 and an igniter 12 connected to the warhead housing 11. A stabilizer 14 is provided to stabilize the descent of the warhead 10 after it has been ejected from the missile or cargo floor. The empennage 14 comprises wing segments 14 a, 14 b, 14 c, which lie against one another, preferably to form a circular area (FIG. 3), and the axes (20 a, 20 b, 20 c) arranged vertically in the igniter 12 in a vertical direction are rotatably mounted to the longitudinal axis of the warhead lying plane. Fig. 3 shows a plan view of only the segments 14 a, 14 b, 14 c, of the tail unit 14, the segments being folded together. Rotation in the direction of the arrows 30 about the axes 20 a, 20 b, 20 c leads to the state shown in FIG. 2, in which the segments 14 a, 14 b, 14 c of the tail unit 14 are unfolded and thereby over the circumference of the The warhead housing 11 protrude. Since the segments 14 a, 14 b, 14 c of the tail unit 14 in the collapsed state (FIG. 3) are supported over the entire surface on the end face of the detonator 12, they are able to absorb very large acceleration forces in the longitudinal axial direction of the warhead 10, although they only consist of a relatively thin flexible material, such as spring steel. In the extended state (FIG. 2), they stabilize the position of the warhead 10 such that it hits the target surface with the opening surface of the shaped charge 14, while at the same time reducing the sinking speed of the warhead in a desired manner.
