Abstract

Für den Geschosskern (11) eines Treibspiegelgeschosses (10) möchte man im Hinblick auf die Wirkung im Ziel sehr spröde Werkstoffe verwenden. Es hat sich nun gezeigt, dass ein Geschosskern (11) aus einem solchen spröden Werkstoff bereits bei der Zufuhr zur Waffe zerbricht. Um diese Gefahr zu vermeiden, wird der spröde Teil (13) des Geschosskerns (11) mit Hilfe eines Zugankers (15) vorgespannt. Vorzugsweise besteht der Geschosskern (11) aus drei Teilen (12,13,14), von denen der Mittelteil (13) vorgespannt ist, und wobei die Berührungsflächen zwischen diesen drei Teilen kegelförmig ausgebildet sind.For the projectile core (11) of a sabot projectile (10) one would like to use very brittle materials with regard to the effect in the target. It has now been shown that a projectile core (11) made of such a brittle material breaks when it is fed to the weapon. To avoid this danger, the brittle part (13) of the projectile core (11) is prestressed with the aid of a tie rod (15). The projectile core (11) preferably consists of three parts (12, 13, 14), of which the central part (13) is prestressed, and the contact surfaces between these three parts are conical.

Description

Die Erfindung betrifft ein Geschoss mit einem Geschosskern und einem Treibspiegelmantel, an dem hinten ein Treibspiegelheck und vorne eine Treibspiegelhaube befestigt ist, wobei der Geschosskern aus drei Teilen besteht, die aus verschiedenen Werkstoffen hergestellt sind und der mittlere Teil des Geschosskernes durch einen Zuganker vorgespannt ist.The invention relates to a projectile with a projectile core and a sabot jacket, to the rear of which is attached a sabot rear and a sabot hood at the front, the projectile core consisting of three parts which are made of different materials and the middle part of the projectile core is prestressed by a tie rod.

Es ist bekannt (siehe EP-A-0 073 385), für solche Geschosse einen Geschosskern aus Wolfram zu verwenden. Insbesondere wird sogenannter frangibler Wolfram verwendet, dessen Druckfestigkeit 10-20mal grösser ist als dessen Zugfestigkeit. Ein solcher Kern aus Wolfram mit sehr kleiner Dehnung (annähernd Null) lässt sich in der herkömmlichen Weise nicht aus Kanonen mit hoher Kadenz verschiessen, da die Gefahr besteht, dass der Geschosskern bereits beim Zuführen des Geschosses zur Feuerwaffe zerbricht. Beim Zuführen des Geschosses zur Waffe, insbesondere beim Einschieben des Geschosses ins Waffenrohr, entstehen grosse Verzögerungskräfte, welche Zugspannungen im Geschosskern erzeugen. Durch diese Zugspannungen kann der Kern vorzeitig zerstört werden.It is known (see EP-A-0 073 385) to use a bullet core made of tungsten for such bullets. In particular, so-called frangible tungsten is used, whose compressive strength is 10-20 times greater than its tensile strength. Such a core made of tungsten with a very low elongation (almost zero) cannot be fired from cannons with a high cadence in the conventional way, since there is a risk that the projectile core will break when the projectile is fed to the firearm. When the projectile is fed to the weapon, in particular when the projectile is inserted into the weapon barrel, great retarding forces arise which generate tensile stresses in the projectile core. The core can be destroyed prematurely by these tensile stresses.

Es ist ferner ein Sprengkörper bekannt (siehe CH-A-­305 149) mit in eine Bindemasse eingebetteten Splittern, bei welchem der die Splitter enthaltende Teil mindestens teilweise durch ein elastisch gespanntes, mechanisches Mittel auf Druck gespannt ist. Der die Splitter enthaltende Teil ist vorzugsweise ein zylinderförmiger Hohlkörper, der ebenfalls durch einen Zuganker vorgespannt ist. Dieser Hohlkörper weist zwei zueinander parallele Stirnflächen an seinen beiden Enden auf, an denen der Zuganker zur Erzeugung einer Vorspannung angreift.An explosive device is also known (see CH-A-305 149) with splinters embedded in a binding mass, in which the part containing the splinters is at least partially tensioned by an elastically tensioned mechanical means. The part containing the splinters is preferably a cylindrical hollow body, which is also biased by a tie rod. This hollow body has two mutually parallel end faces at its two ends which the tie rod attacks to generate a preload.

Es hat sich nun gezeigt, dass bei parallelen Stirnflächen die Gefahr besteht, dass der zylindrische Hohlkörper durch die Vorspannung zerbricht.It has now been shown that with parallel end faces there is a risk that the cylindrical hollow body will break due to the prestress.

Die Aufgabe, welche mit der vorliegenden Erfindung gelöst werden soll, besteht in der Schaffung eines Geschosskörpers, der eine grosse Vorspannung aushält, ohne dass die Gefahr besteht, dass er unter der Wirkung dieser Vorspannung zerbricht.The object which is to be achieved with the present invention is to create a projectile body which can withstand a large preload without the risk of it breaking under the effect of this preload.

Das erfindungsgemässe Geschoss, mit dem diese Aufgabe gelöst wird, ist dadurch gekennzeichnet, dass die beiden Stirnflächen des mittleren Teiles, an denen die anderen beiden Teile, d.h. die Spitze und das Heck des Geschosskernes anliegen, kegelförmig ausgebildet sind, mit einem Kegelspitzwinkel kleiner als 180°, und dass die Stirnflächen der anderen beiden Teile, welche an diesen Stirnflächen des mittleren Teiles anliegen, ebenfalls kegelförmig ausgebildet sind, mit einem Kegelspitzwinkel grösser als 180°, wobei diese beiden Winkel sich auf 360° ergänzen.The projectile according to the invention with which this object is achieved is characterized in that the two end faces of the central part, on which the other two parts, i.e. the tip and the rear of the projectile core rest, are conical in shape, with a cone angle less than 180 °, and that the end faces of the other two parts, which rest on these end faces of the central part, are also conical, with a cone angle greater than 180 °, where these two angles add up to 360 °.

Diese Ausbildung des Geschosskernes hat folgende Vorteile:This design of the storey core has the following advantages:

Durch die kegelförmigen Stirnflächen an beiden Enden des mittleren Teiles entsteht beim Auftreffen und Eindringen des Geschosses in ein Ziel eine Fokussierung der Druck- ­und Schockwellen, daraus ergibt sich eine erhöhte Durchschlagsleistung bei leicht gepanzerten Zielen, ein verzögertes Zerbrechen des zerbrechlichen Kernmittelteiles und somit eine grössere Tiefenwirkung, d.h. grösseres Zerstörungsvolumen bei ungepanzerten Zielen und eine zusätzliche Verbesserung der Zentrierung des Mittelteiles beim Zusammensetzen der drei Teile.Due to the conical end faces at both ends of the middle part, when the bullet hits and penetrates into a target, the pressure and shock waves focus, resulting in increased penetration performance with slightly armored targets, a delayed breaking of the fragile core middle part and thus a greater depth effect , ie greater destruction volume in the case of unarmored targets and an additional improvement in the centering of the middle part when assembling the three parts.

Verschiedene Ausführungsbeispiele des erfindungsgemässen Geschosses sind anhand der beigefügten Zeichnung im folgenden ausführlich beschrieben. Es zeigt:

  • Fig.1 einen Längsschnitt durch das erfindungsgemässe Geschoss;
  • Fig.2 einen Längsschnitt durch einen Geschosskern gemäss einem zweiten Ausführungsbeispiel;
  • Fig.3 einen Längsschnitt durch einen Geschosskern gemäss einem dritten Ausführungsbeispiel; und
  • Fig.4 einen Längsschnitt durch einen Geschosskern gemäss einem vierten Ausführungsbeispiel.

Gemäss Fig.1 weist das erfindungsgemässe Geschoss 10 einen Geschosskern 11 auf. Dieser Geschosskern 11 besteht aus drei Teilen 12,13 und 14, welche durch einen Zuganker 15 zusammengehalten werden. Dieser Zuganker 15 ist vorne in die Geschosskernspitze 12 und hinten in das Geschosskernheck 14 eingeschraubt, wobei die drei Teile 12,13 und 14 derart aneinander gepresst werden können, dass der im wesentlichen zylindrische Mittelteil 13 unter Vorspannung steht. Die beiden Stirnflächen 43,44 des im wesentlichen zylindrischen Mittelteiles 13, an denen die anderen beiden Teile 12 und 14, d.h. die Spitze 12 und das Heck 14 des Geschosskernes 11 anliegen, sind kegelförmig ausgebildet, wobei der Kegelspitzwinkel α kleiner als 180° ist. Die Stirnflächen 45,46 der anderen beiden Teile 12 und 14, welche an diesen Stirnflächen 43,44 des mittleren Teiles 13 anliegen, sind ebenfalls kegelförmig ausgebildet, wobei der Kegelspitzwinkel β grösser als 180° ist. Diese beiden Kegelspitzwinkel α und β ergänzen sich auf 360°, wie aus der Zeichnung ersichtlich ist.1, the projectile 10 according to the invention has a projectile core 11. This projectile core 11 consists of three parts 12, 13 and 14, which are held together by a tie rod 15. This tie rod 15 is screwed into the projectile core tip 12 at the front and into the projectile core rear 14 at the rear, the three parts 12, 13 and 14 being able to be pressed against one another in such a way that the essentially cylindrical central part 13 is under prestress. The two end faces 43, 44 of the substantially cylindrical central part 13, on which the other two parts 12 and 14, i.e. the tip 12 and the rear 14 of the projectile core 11 are conical, the cone tip angle α being less than 180 °. The end faces 45, 46 of the other two parts 12 and 14, which abut these end faces 43, 44 of the middle part 13, are also conical, the cone angle β being greater than 180 °. These two cone angles α and β add up to 360 °, as can be seen from the drawing.

Der Geschosskern 11 steckt in einem ringförmigen Treibspiegelheck 16. Zur Befestigung des Geschosskernes 11 im Treibspiegelheck 16 sind im Geschosskernheck 14 zwei Umfangsnuten 17 vorhanden, in welche eine Anzahl gleichmässig am Umfang verteilter Nocken 18 des Treibspiegelhecks 16 hineinragen. Am Treibspiegelheck 16 wird durch eine innere Umfangsnut 19 eine Sollbruchstelle 20 gebildet. Oberhalb dieser Sollbruchstelle 20 besitzt das Treibspiegelheck 16 eine Anzahl Zungen 21, an denen sich je zwei Nocken 18 befinden. Beim Abschuss des Geschosses 10 kann sich der Geschosskern 11 auf einer konischen Fläche 22 des Treibspiegelhecks 16 abstützen. Am Treibspiegelheck 16 ist ferner ein Treibspiegelmantel 23 befestigt, auf den eine Treibspiegelhaube 24 aufgesetzt ist.The projectile core 11 is located in an annular sabot rear 16 for fastening the projectile core 11 in the sabot rear end 16 there are two circumferential grooves 17 in the projectile core rear end 14, into which a number of cams 18 of the sabot rear end 16 distributed uniformly over the circumference protrude. A predetermined breaking point 20 is formed on the sabot rear end 16 by an inner circumferential groove 19. Above this predetermined breaking point 20, the sabot rear 16 has a number of tongues 21, on each of which there are two cams 18. When the projectile 10 is fired, the projectile core 11 can be supported on a conical surface 22 of the sabot rear 16. A sabot jacket 23 is also attached to the sabot rear end 16, on which a sabot cover 24 is placed.

Der Treibspiegel besteht somit aus einem Treibspiegelheck 16, einem Treibspiegelmantel 23 und einer Treibspiegelhaube 24. Dieser Treibspiegel ist jedoch nicht Gegenstand der Erfindung und soll daher hier nicht näher erläutert werden.The sabot thus consists of a sabot rear 16, a sabot jacket 23 and a sabot cover 24. However, this sabot is not the subject of the invention and is therefore not to be explained in more detail here.

Für die einzelnen Teile des Geschosses werden vorzugsweise folgende Werkstoffe verwendet:The following materials are preferably used for the individual parts of the floor:

Für den Mittelteil 13 wird vorzugsweise frangibles Wolfram verwendet, bei dem die Druckfestigkeit 10-20mal höher ist als die Zugfestigkeit.
