Warhead including a first (HL1) and a second (HL2) hollow charge, disposed axially in series, whereby the second hollow charge is ignited after expiration of a time delay following ignition of the first hollow charge, characterised by the following features : the igniting devices for the first hollow charge (HL1), which is accommodated in the spacer section (A) of the warhead (1), and for the second hollow charge (HL2) are independent of each other, in which respect the one for the first hollow charge (HL1) is ignited by way of an impact switch (K1) accommodated in the tip of the spacer section (A), and the one for the second hollow charge (HL2) is ignited by way of a shoulder contact (K2) on the warhead shroud ; a barrier (B) which deflects retro-action of the detonation products is disposed between the first and the second hollow charge, and a predetermined breaking point (SB) is provided in the warhead shroud.

Description

Die Erfindung betrifft einen Gefechtskopf mit einer ersten und einer zweiten axial hintereinanderliegenden und jeweils eine Zündeinrichtung aufweisenden Hohlladung, wobei die zweite Hohlladung nach einer wählbaren Verzögerungszeit nach der ersten Hohlladung zündbar ist.The invention relates to a warhead with a first and a second axially one after the other and each having an ignition device shaped charge, the second shaped charge being ignitable after a selectable delay time after the first shaped charge.

Hohlladungsgeschosse erzeugen mittels ihrer detonierenden Sprengladung einen energiereichen langgezogenen Stachel, der auch Panzerungen mit hoher Festigkeit zu durchdringen vermag. Als Auslösevorrichtung hierfür ist beispielsweise aus der DE-PS 32 43 568 ein Abstandshalter bekannt, der sowohl an seiner Spitze als auch an der Schulter seines Hohlladungsmantels einen Aufschlagkontakt aufweist. Diese Konstruktion stellt für ein Geschoß mit nur einer Hohlladung eine zufriedenstellende Lösung dar.With their detonating explosive charge, shaped charge bullets create an energetic elongated spike that can penetrate armor with high strength. As a triggering device for this purpose, a spacer is known from DE-PS 32 43 568, for example, which has an impact contact both at its tip and at the shoulder of its shaped charge jacket. This construction is a satisfactory solution for a storey with only one shaped charge.

Aus der DE-OS 24 60 303 ist ein kombiniertes Hohlladungsgeschoß bekannt, welches zwei axial hintereinanderliegende Hohlladungen etwa gleicher Größe enthält. 'Beide Hohlladungen weisen jeweils eine eigene Zündeinrichtung auf, wobei eine Zeitverzögerungseinrichtung zur Ansteuerung der zweiten Hohlladung bei Auslösung der ersten Hohlladung benötigt wird. Dies bedingt einen bestimmten gerätetechnischen Aufwand und außerdem noch eine elektrische Verbindung von der ersten zu der zweiten Zündeinrichtung, die zudem noch ungünstigerweise im Stachelbildungsraum der zweiten Hohlladung verlegt sein muß.From DE-OS 24 60 303 a combined shaped charge projectile is known which contains two shaped charges lying axially one behind the other of approximately the same size. Both shaped charges each have their own ignition device, a time delay device being required to control the second shaped charge when the first shaped charge is triggered. This requires a certain amount of equipment and also an electrical connection from the first to the second ignition device, which also has to be unfavorably installed in the spike formation space of the second shaped charge.

Es liegt daher der Erfindung die Aufgabe zugrunde, eine vereinfachte Zündeinrichtung für einen Gefechtsdkopf mit zwei axial hintereinanderliegenden Hohlladungen zu schaffen, die die vorgenannten Nachteile vermeidet.It is therefore the object of the invention to provide a simplified ignition device for a warhead to create with two axially consecutive shaped charges, which avoids the aforementioned disadvantages.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die erste im Abstandshalter des Gefechtskopfes angeordnete Hohlladung in an sich bekannter Weise mittels eines in der Spitze des Abstandshalters angebrachten Aufschlagschalters zündbar ist und daß die zweite Hohlladung unabhängig von der ersten Hohlladung mittels mindestens eines Aufschlagkontaktes, der in der Schulter des Gefechtskopfmantels angeordnet ist, auslösbar ist.This object is achieved in that the first shaped charge arranged in the spacer of the warhead can be ignited in a manner known per se by means of an impact switch attached in the tip of the spacer, and in that the second shaped charge is independent of the first shaped charge by means of at least one impact contact which is in the Shoulder of the warhead shell is arranged, can be triggered.

Ein Ausführungsbeispiel der Erfindung ist in der einzigen Figur der Zeichnung dargestellt und wird nachfolgend näher beschrieben.An embodiment of the invention is shown in the single figure of the drawing and is described in more detail below.

Der Gefechtskopf 1 ist so geformt, daß er als in Wirkrichtung seiner Hohlladungen weisende Fortsetzung seines dicker ausgeführten Hauptkörpers einen Abstandshalter A aufweist. Dieser Abstandshalter A enthält eine Hohlladung HL1, deren Zünd- und Sicherungseinrichtung SEI, die - in Wirkrichtung gesehen - hinter der Hohlladung HL1 angeordnet ist, durch einen in der Spitze des Abstandshalters A angebrachten Aufschlagschalter Kl ausgelöst werden kann. Dieser Aufschlagschalter Kl kann je nach Anwendungsfall beispielsweise als einfacher Schaltkontakt, als Piezoelement oder als ein aus dem Stand der Technik geläufiger Kontakt ausgeführt sein. Der Abstandshalter A enthält weiterhin im Bereich seines Halses eine Barriere B und eine Sollbruchstelle SB, die im Falle der Auslösung der Hohlladung HL1 eine Rückwirkung auf die Auskleidung der Hohlladung HL2 vermeiden.The warhead 1 is shaped such that it has a spacer A as a continuation of its thicker main body, pointing in the direction of action of its shaped charges. This spacer A contains a shaped charge HL1, the ignition and safety device SEI, which - as seen in the effective direction - is arranged behind the shaped charge HL1, can be triggered by an impact switch Kl mounted in the tip of the spacer A. Depending on the application, this impact switch K 1 can be designed, for example, as a simple switching contact, as a piezo element or as a contact familiar from the prior art. The spacer A also contains a barrier B and a predetermined breaking point SB in the region of its neck, which prevent the hollow charge HL2 from being lined up if the shaped charge HL1 is triggered.

Die zweite Hohlladung HL2, die zusammen mit ihrer Zünd- und Sicherungseinrichtung SE2 axial hinter der Hohlladung HL2 liegt, ist mittels eines eigenen Aufschlagkontaktes K2 völlig unabhängig von der in der Regel zuerst ausgelösten Hohlladung HL1 zu initiieren. Dieser Aufschlagkontakt K2 ist hier im Beispiel als ein in der Schulter S des Gefechtskopfmantels integrierter Aufschlagschalter einfachster Bauart realisiert worden. Andere Schalterausführungen sind im Rahmen dieser Erfindung nicht ausgeschlossen.The second shaped charge HL2, which, together with its ignition and safety device SE2, lies axially behind the shaped charge HL2, is to be initiated completely independently of the shaped charge HL1, which is generally triggered first, by means of its own impact contact K2. In the example, this impact contact K2 has been implemented as a simplest type of impact switch integrated in the shoulder S of the warhead shell. Other switch designs are not excluded within the scope of this invention.

Trifft ein derartig ausgerüsteter Gefechtskopf auf ein Ziel, wobei hier besonders an den Anwendungsfall dieser Waffe gegen aktive Panzerungen gedacht ist, so löst der Kontakt Kl über die Zünd- und Sicherungseinrichtung SE1 die Hohlladung HL1 aus. Dies Hohlladung bohrt nun ein Loch in die getroffene Panzerung oder löst im Fall einer aktiven Panzerung diese am Auftreffpunkt aus. Der Abstandshalter A ist so ausgerüstet, daß er mittels der Barriere BAR eine Rückwirkung seines Detonationsdruckes auf die nachfolgende Hohlladung HL2 vermeidet und durch Abbrechen an der Sollbruchstelle SB der zweiten Hohlladung HL2 freihält. Dieser Stachelbildungsraum SR wird auch aufgrund der erfindungsgemäßen Ausführungsform durch keinerlei elektrische oder sonstige Verbindungen gestört.If a warhead equipped in this way hits a target, with the use of this weapon against active armor being particularly considered here, the contact K1 triggers the shaped charge HL1 via the ignition and safety device SE1. This shaped charge now drills a hole in the armor or, in the case of active armor, triggers it at the point of impact. The spacer A is equipped in such a way that, by means of the barrier BAR, it avoids a reaction of its detonation pressure on the subsequent shaped charge HL2 and keeps it free of the second shaped charge HL2 by breaking off at the predetermined breaking point SB. Because of the embodiment according to the invention, this spike formation space SR is not disturbed by any electrical or other connections.

Die zweite Hohlladung HL2 wird erst bei der Zielberührung durch den zweiten Aufschlagkontakt K2 durch die Zünd- und Sicherungseinrichtung SE2 ausgelöst. Allein durch die Wegdifferenz zwischen den Aufschlagkontakten Kl und K2 wird die gewünschte Zeitdifferenz zwischen den Zündungen der beiden Hohlladungen erzielt. Damit können aufwendige Zeitverzögerungsschaltungen in der Zünd- und Sicherungseinrichtung SE2 entfallen.The second shaped charge HL2 is only triggered when the target touches the second impact contact K2 by the ignition and safety device SE2. The desired time difference between the firings of the two shaped charges is achieved solely by the path difference between the impact contacts K1 and K2. This eliminates the need for time-consuming delay circuits in the ignition and fuse device SE2.

Der besondere Vorteil des erfindungsgemäßen Gefechtskopfes ist darin zu sehen, daß er mit einem geringen Aufwand zur Zündung seiner Hohlladungen auskommt und daß gleichzeitig seine Wirksamkeit erhöht wird.The particular advantage of the warhead according to the invention can be seen in the fact that it requires little effort to ignite its shaped charges and that its effectiveness is increased at the same time.
