Abstract

An armor-penetrating projectile comprises an outer substantially cylindrically tubular member of great length/diameter ratio and density, centered on an axis, and having an axially throughgoing bore defined by an inner surface and an axially elongated inner member of greater strength and elasticity than the outer member extending axially through the bore the full length of the outer member and having an outer surface in tight radial contact with the inner surface of the outer member at at least a plurality of annular locations spaced along the axis. This inner member can be a bundle of wires that is inserted through the bore after the outer member has been expanded by heat, then twisted and longitudinally prestressed to lock tightly in the outer member.

Description

Die Erfindung betrifft ein panzerbrechendes Wuchtgeschoß mit dem Merkmal des Oberbegriffs des Patentanspruchs 1.The invention relates to an armor-piercing balancing projectile with the feature of the preamble of patent claim 1.

Ein solches sogenanntes Langgeschoß ist aus der DE-C-14 28 679 bekannt. Dort sind in einer das ganze Geschoß umgebenden Hülle als Halteelement Hartkernelemente und dazwischen dämpfende Elemente angeordnet. Es sollen überkalibergroße Löcher in einer Zielplatte erzeugt werden, um das Heckteil des Geschosses ungehindert passieren zu lassen. Bei dem Einsatz eines solchen Geschosses auf eine geneigte sehr dicke Panzerplatte neigt sich die Achse eines sich bildenden Durchdringungskanals nach einer Seite hin, sobald die Entfernung dahin zum Plattenrand kürzer ist, als in gerader Richtung zum Plattenrand hin. Hierdurch kommt es bei dem bekannten Geschoß, insbesondere infolge der Hülle und der Dämpfungselemente, sowie auch infolge der kegeligen Spitze des Heckteils zu einem Ablenken des Heckteils, wodurch bei Mehrplattenzielen die Zielwirksamkeit des Geschosses empfindlich beeinträchtigt wird.Such a so-called long floor is known from DE-C-14 28 679. There, hard core elements and damping elements are arranged in a shell surrounding the entire floor as a holding element. Oversize-sized holes are to be created in a target plate in order to allow the rear part of the projectile to pass unhindered. When such a projectile is used on an inclined, very thick armor plate, the axis of a penetration channel which forms is inclined to one side as soon as the distance to the plate edge is shorter than in a straight direction to the plate edge. This leads to a deflection of the rear part in the known projectile, in particular as a result of the casing and the damping elements, and also as a result of the conical tip of the rear part, as a result of which the target effectiveness of the projectile is severely impaired in the case of multi-plate targets.

Aus der DE-C-85 148 ist ein Kurzgeschoß mit einem panzerbrechenden Kern relativ großen Länge/Durchmesserverhältnisses bekannt. Der Kern ist von einem Geschoßmantel, ähnlich einem Treibkäfig, umgeben. Der Geschoßmantel bleibt beim Eindringen des Kerns in eine Zielplatte zurück.From DE-C-85 148 a short storey with an armor-piercing core of relatively large length / diameter ratio is known. The core is surrounded by a bullet jacket, similar to a sabot. The projectile jacket remains when the core penetrates a target plate.

Aus der EP-A-00 13 367 ist ein anderes Kurzgeschoß bekannt, bei dem eim panzerbrechender Geschoßmantel um einen Kern als Halteelement gewickelt ist.Another short projectile is known from EP-A-00 13 367, in which an armor-piercing projectile jacket is wound around a core as a holding element.

Beide Ausführungsformen nach dem vorstehend genannten Stand der Technik verhindern nicht das Ablenken des Geschosses beim Einsatz gegen Mehrfachziele. Das gleiche gilt für Figur 3 der EP-A-00 51 375, bei dem ein von der Spitze ausgehendes Halteelement sich durch den Geschoßkörper hindurch erstreckt.Both embodiments according to the aforementioned prior art do not prevent the projectile from being deflected when used against multiple targets. The same applies to Figure 3 of EP-A-00 51 375, in which a holding element extending from the tip extends through the projectile body.

Aufgabe der Erfindung ist es, das eingangs erwähnte Geschoß für den Einsatz auf Mehrfachziele dahingehend zu verbessern, daß es einerseits nicht aus seiner Eindringrichtung abgelenkt wird und daß andererseits beim Bruch des Heckteils an die Masse der Bruchstücke gebundene Energie für die weitere Durchschlagsarbeit voll ausnutzbar ist.The object of the invention is to improve the projectile mentioned at the outset for use on multiple targets in such a way that, on the one hand, it is not deflected from its direction of penetration and, on the other hand, when the rear part breaks, the energy bound to the mass of the fragments can be fully utilized for further penetration work.

Die zur Lösung der gestellten Aufgabe wesentlichen notwendigen Merkmale der Erfindung sind im Patentanspruch 1 genannt. Die Unteransprüche nennen Ausführungsarten der Erfindung.The features of the invention that are essential for achieving the object are mentioned in claim 1. The subclaims list embodiments of the invention.

Durch die Erfindung ist gewährleistet, daß auch bei Brüchen quer zur Heckteillängsachse die Bruchstücke miteinander vereinigt und somit auch weiterhin an der Durchschlagsarbeit beteiligt bleiben.The invention ensures that the fragments are combined with one another even in the event of breaks transversely to the longitudinal axis of the rear part and thus continue to be involved in the penetration work.

Die Erfindung wird nachstehend anhand dreier in der Zeichnung dargestellter Ausführungsbeispiele des näheren erläutert.The invention is explained below with reference to three exemplary embodiments shown in the drawing.

Es zeigt, jeweils schematisch und unter Verzicht auf erfindungsunwesentliche Einzelheiten sowie im wesentlichen ausschnittweise :

  • Figur 1 ein erstes Ausführungsbeispiel im längsaxialen Schnitt,
  • Figur 2 ausschnittweise ein zweites Ausführungsbeispiel für ein Halteelement im seitlichen Aufriß und
  • Figur 3 ein zweites Ausführungsbeispiel im Schnitt quer zur Längsachse.
It shows, in each case schematically and without details that are not essential to the invention and essentially in sections:
  • FIG. 1 shows a first embodiment in a longitudinal axial section,
  • Figure 2 shows a detail of a second embodiment of a holding element in side elevation and
  • Figure 3 shows a second embodiment in section transverse to the longitudinal axis.

Nach Figur 1 weist ein Hauptpenetrator 1 großen Länge/Durchmesser-Verhältnisses und hoher Dichte (beispielsweise durch Verwendung eines Schwermetall-Sinterverbundwerkstoffs) mit einer Umfangsfläche 2 und einander abgewandten Stirnflächen 3 und 4 eine sich entlang einer zentralen Längsachse erstreckende Zentralbohrung 5 auf. In der Zentralbohrung 5 ist ein Halteelement 10 mit einem Draht 10' angeordnet, bei welchem Bereiche 13 und 15 unterschiedlicher Durchmesser einander benachbart sind. Zwischen Umfangsflächen 14 der Bereiche 13 und der Wandfläche 6 besteht Kraftschluß infolge Schrumpfsitzes. Auch jeweilige Enden 11, 12 des Halteelements 10 bildenden Stehbolzen 17 und 18 sind in den Penetrator eingeschrumpft. Ein Übergang 14' zwischen den Bereichen 13 und 15 ist ausgerundet. Die Bereiche 15 sind von Hohlräumen 16 umgeben.According to FIG. 1, a main penetrator 1 with a large length / diameter ratio and high density (for example by using a heavy metal sintered composite material) with a peripheral surface 2 and facing end faces 3 and 4 has a central bore 5 extending along a central longitudinal axis. A holding element 10 with a wire 10 'is arranged in the central bore 5, in which regions 13 and 15 of different diameters are adjacent to one another. Between circumferential surfaces 14 of the areas 13 and the wall surface 6 there is frictional engagement due to the shrink fit. The respective ends 11, 12 of the stud bolts 17 and 18 forming the holding element 10 are also shrunk into the penetrator. A transition 14 'between the areas 13 and 15 is rounded. The areas 15 are surrounded by cavities 16.

In Figur 2 ist ein Halteelement 10 durch mehrere Drähte 10' gebildet. Die Drähte 10' sind mit Abständen voneinander mit einer Schicht 13' versehen, deren Umfangsbereich 14 zum Kraftschluß mit der Wandfläche 6 der Zentralbohrung 5 vorgesehen ist. Die Drähte 10' künnen verdrillt sein.In Figure 2, a holding element 10 is formed by a plurality of wires 10 '. The wires 10 'are spaced apart from one another by a layer 13', the peripheral region 14 of which is provided for the frictional connection with the wall surface 6 of the central bore 5. The wires 10 'can be twisted.

In Figur 3 ist ein Halteelement 30 als Seil aus verdrillten Drähten 31 ausgebildet. Zwischen Umfangsflächen 14' der Drähte 31 und der Wandfläche 6 der Bohrung 5 besteht Kraftschluß. Die Kraftschlußzonen erstrecken sich entlang Schraubenbändern, welche Bereiche 16' gegeneinander abgrenzen.In Figure 3, a holding element 30 is formed as a rope made of twisted wires 31. Between the peripheral surfaces 14 'of the wires 31 and the wall surface 6 of the bore 5 there is frictional connection. The non-positive zones extend along screw bands which delimit regions 16 'from one another.

Zum Herstellen des Hauptpenetrators nach der Erfindung wird im Falle beider Ausführungsbeispiele folgendermaßen verfahren :

  • Der Hauptpenetrator 1 wird erwärmt und der Innendurchmesser der Zentralbohrung 5 vergrößert sich hierbei von einem Ausgangswert do auf di. Bei den Ausführungsbeispielen nach Figur 1 und 2 wird nun das Halteelement 10 mit einem größten Außendurchmesser D in die Zentralbohrung 5 eingebracht, positioniert und der Hauptpenetrator 1 wieder abgekühlt. Der Außendurchmesser D erfüllt dabei die Bedingung do < D < dl, so daß beim Erreichen der Ausgangstemperatur infolge Schrumpfens zwischen den Flächenbereichen 14 und der Wandungsfläche 6 Kraftschluß verwirklicht wird.
To produce the main penetrator according to the invention, the procedure for both exemplary embodiments is as follows:
  • The main penetrator 1 is heated and the inner diameter of the central bore 5 increases from an initial value d o to d i . In the exemplary embodiments according to FIGS. 1 and 2, the holding element 10 with a largest outer diameter D is now introduced into the central bore 5, positioned and the main penetrator 1 is cooled again. The outer diameter D fulfills the condition d o <D <d l , so that when the initial temperature is reached due to shrinkage between the surface regions 14 and the wall surface 6, frictional connection is achieved.

Beim Ausführungsbeispiel nach Figur 3 wird nach dem Erwärmen des Hauptpenetrators 1 ein Bündel von Drähten 31 in die Zentralbohrung 5 eingebracht, deren Enden zu beiden Seiten über die nicht dargestellten Stirnflächen des Hauptpenetrators 1 überstehen. Das Drahtbündel füllt den gesamten Bohrungsquerschnitt aus. Beide Enden werden nun auseinander gezogen, die Drähte 31 werden gereckt und gleichzeitig verdrillt. Ein infolge Einschnürung der Drähte 31 verringerter Bündelquerschnitt vergrößert sich durch das Verdrillen. Der Hauptpenetrator 1 wird abgekühlt und das Halteelement 30 dabei eingeschrumpft, so daß es zu dem gegenseitigen Kraftschluß kommt. Sobald der Hauptpenetrator 1 seine Ausgangstemperatur wieder erreicht hat, verbleibt in den Kraftschlußbereichen neben der radial wirkenden Flächenpressung eine dieser überlagerte axiale Spannungskomponente.In the exemplary embodiment according to FIG. 3, after the main penetrator 1 has been heated, a bundle of wires 31 is introduced into the central bore 5, the ends of which extend over on both sides the end faces of the main penetrator 1, not shown, protrude. The wire bundle fills the entire cross section of the hole. Both ends are now pulled apart, the wires 31 are stretched and twisted at the same time. A bundle cross section which is reduced as a result of constriction of the wires 31 increases as a result of the twisting. The main penetrator 1 is cooled and the holding element 30 is shrunk in, so that there is mutual frictional connection. As soon as the main penetrator 1 has reached its initial temperature again, in addition to the radially acting surface pressure, one of these superimposed axial tension components remains in the non-positive areas.

Wenn beim Auftreffen auf ein gepanzertes Ziel die Wandung 7 des Hauptpenetrators 1 quer zur Längsachse A bricht, bleiben die Bruchstücke entlang der Längsachse A in Richtung miteinander vereinigt und infolgedessen unter im wesentlichen optimalen Bedingungen an der Durchschlagsarbeit beteiligt. Dabei weist ein Hauptpenetrator nach der Erfindung gegenüber einem solchen mit einer Hülle als Halteelement, beispielsweise aus Stahl, wesentliche Vorteile auf : mit Rücksicht auf ein umfangsseitig erforderliches Gewinde oder dergleichen zum axialen Formschluß mit einem Treibkäfig muß die Hülle eine ausreichende Wandstärke haben, wodurch nachteiligerweise die mittlere Dichte empfindlich beeinträchtigt wird. Demgegenüber wird bei der Anordnung nach der Erfindung ein Halteelement mit einem vergleichsweise wesentlich geringeren Volumen realisiert. Da dieses zudem im Innern des Querschnitts angeordnet ist, ist der Zielwerkstoff immer einem scharfkantigen Rand des dichten Verbundwerkstoffs ausgesetzt.If, when striking an armored target, the wall 7 of the main penetrator 1 breaks transversely to the longitudinal axis A, the fragments remain joined together along the longitudinal axis A and consequently participate in the penetration work under essentially optimal conditions. In this case, a main penetrator according to the invention has significant advantages over one with a sleeve as a holding element, for example made of steel: with regard to a thread or the like required for the circumference for the axial positive locking with a sabot, the sleeve must have a sufficient wall thickness, which disadvantageously means that medium density is significantly affected. In contrast, a holding element with a comparatively substantially smaller volume is realized in the arrangement according to the invention. Since this is also arranged inside the cross-section, the target material is always exposed to a sharp-edged edge of the dense composite material.

Wie aus dem Ausführungsbeispiel gemäß Figur 1 erkennbar, kann das Halteelement an wenigstens einem seiner beiden Enden einen Stehbolzen aufweisen, welcher ebenfalls eingeschrumpft ist und mit einem freien Ende, welches ein Gewinde aufweist, über eine betreffende Stirnfläche 3 oder 4 des Hauptpenetrators 1 übersteht. Er kann folglich zum Verbinden eines Vorpenetrators oder der Aufnahme eines heckseitigen Trägers für ein Stabilisierungsleitwerk über das Gewinde 19 bzw. 20 dienen.As can be seen from the exemplary embodiment according to FIG. 1, the holding element can have a stud at at least one of its two ends, which is also shrunk in and protrudes with a free end, which has a thread, over a respective end face 3 or 4 of the main penetrator 1. It can therefore be used to connect a pre-penetrator or to accommodate a rear-side support for a stabilizing tail unit via the thread 19 or 20.

Die Schicht 13' (Fig. 2) kann aus duktilem und damit schockabsorbierendem Werkstoff ausreichender Festigkeit bestehen. Es eigenen sich hierfür, beispielsweise, Kupferlegierungen, die außerdem eine ausreichende Reibung mit dem Penetratorwerkstoff unter dem bestehenden gegenseitigen Kraftschluß gewährleisten.The layer 13 '(Fig. 2) can consist of ductile and thus shock-absorbing material of sufficient strength. For this purpose, copper alloys are suitable, for example, which also ensure sufficient friction with the penetrator material under the existing mutual adhesion.
