Description

Die Erfindung betrifft ein Unterkalibergeschoss mit einem abwerfbaren Treibspiegel und einem Geschosskörper, der im Treibspiegel gehalten wird.The invention relates to a sub-caliber floor with a dropping sabot and a projectile body that is held in the sabot.

Bei Unterkalibergeschossen, wie beispielsweise aus der EP-A-0 624 774 bekannt, besteht der Treibspiegel in der Regel aus einem Treibspiegelmantel aus Kunststoff und einem Treibspiegelkörper aus Metall. Der Geschosskörper (Penetrator) ist meistens ein Pfeilgeschoss, das mit dem Treibspiegelkörper fest verschraubt ist und dessen mit einem Stabilisierungsflügel versehenes Ende aus dem Heck des Treibspiegels herausragt. Der Treibspiegelmantel und der Treibspiegelkörper sind derart in Segmente unterteilt, dass Sollbruchstellen gebildet werden, womit erreicht wird, dass der Treibspiegelmantel und der Treibspiegelkörper unmittelbar nach dem Abschuss abgeworfen werden. In the case of sub-caliber bullets, as known for example from EP-A-0 624 774 , the sabot generally consists of a sabot jacket made of plastic and a sabot body made of metal. The projectile body (penetrator) is usually an arrow projectile, which is screwed to the sabot body and whose end provided with a stabilizing wing protrudes from the rear of the sabot. The sabot jacket and the sabot body are divided into segments such that predetermined breaking points are formed, with the result that the sabot jacket and the sabot body are thrown off immediately after the launch.

Mit der EP-A-0 645 600 ist ein abwerfbarer Treibspiegel für ein Unterkalibergeschoss bekannt geworden, der einteilig ausgebildet ist und somit den Treibspiegelmantel und den Treibspiegelkörper in einem Stück vereint, wobei durch den Wegfall eines separaten Treibspiegelkörpers gegenüber dem vorstehend genannten Stand der Technik Vorteile erzielt werden. EP-A-0 645 600 discloses a detachable sabot for a sub-caliber floor, which is formed in one piece and thus combines the sabot jacket and the sabot body in one piece, the advantages of having no separate sabot body over the prior art mentioned above be achieved.

Ausgehend vom zuletzt genannten Stand der Technik wird die Aufgabe gestellt, Unterkalibergeschosse gemäss Oberbegriff vorzuschlagen, die einen vom Geschosskörper des zuerst genannten Standes der Technik verschiedenen Geschosskörper aufweisen und insbesondere als Übungsmunition geeignet sind.Starting from the last-mentioned state of the art, the task is set, sub-caliber floors to propose according to the generic term that one of the projectile body of the have the first mentioned prior art different projectile bodies and are particularly suitable as practice ammunition.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. Hierbei ist der Geschosskörper als Zerschellpenetrator ausgebildet, der aus mehreren Teilen zusammengesetzt ist, wobei zwischen den Teilen Sollbruchstellen vorgesehen sind. Nach einer vorteilhaften Weiterbildung der Erfindung greifen die Teile an den Sollbruchstellen unter Einhaltung eines Abstandes ineinander und sind mittels eines hochwarmfesten, faserverstärkten, thermoplastischen Kunststoffes miteinander verbunden.This object is achieved by the invention specified in claim 1 . Here, the projectile body is designed as a shattering penetrator, which is composed of several parts, predetermined breaking points being provided between the parts. According to an advantageous development of the invention, the parts engage in one another at the predetermined breaking points while maintaining a distance and are connected to one another by means of a heat-resistant, fiber-reinforced, thermoplastic.

Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass durch Optimierung der Gestaltung des Zerschellpenetrators einerseits der Zerschellpenetrator die Zuführung in der Waffe und den Abschussschock übersteht sowie auf der Flugbahn bei geringen Anstellwinkeln nicht zerbricht. Andererseits wird durch die Optimierung erreicht, dass beim Auftreffen im Ziel, vor allem auf Sand unter flachem Winkel, der Abpralleffekt (Ricochet-Effekt) stark verkleinert oder sogar vermieden wird, was durch die beim Zerbrechen des Zerschellpenetrators auftretende Verkleinerung der Masse und Erhöhung des Luftwiderstandes erreicht wird.The advantages achieved with the invention can be seen in that by optimizing the Design of the crush penetrator on the one hand the crush penetrator in the weapon and the launch shock survive as well as on the trajectory at low angles of attack does not break. On the other hand, the optimization ensures that the Impact at the target, especially on sand at a flat angle, the rebound effect (ricochet effect) greatly reduced or even avoided, which is due to the breakage of the Shattering penetrator occurring reduction in mass and increase in air resistance is achieved.

Gemäss den Fig. 2 und 3 weist die am ersten, vordersten Teil 21 angeordnete Geschossspitze 20 einen Zapfen 36 bzw. 37 auf, der in eine mit Halterillen versehene Bohrung 38 bzw. 39 des ersten, vordersten Teiles 21 eingreift, wobei der Zapfen 36 und die Bohrung 38 sich bis in den Ansatz 26 des ersten, vordersten Teiles 21 hinein erstrecken (Fig. 2).According to FIGS. 2 and 3 , the projectile tip 20 arranged on the first, foremost part 21 has a pin 36 or 37 , which engages in a bore 38 or 39 of the first, foremost part 21 provided with retaining grooves, the pin 36 and the bore 38 extends into the extension 26 of the first, foremost part 21 ( FIG. 2 ).

Nach der Fig. 4 besteht der Zerschellpenetrator 2 aus einer Geschossspitze 50 und einem ersten, zweiten und dritten Teil 51, 52 und 53. Zwischen den Teilen 51, 52, 53 sind Sollbruchstellen 54 vorgesehen. Die Sollbruchstellen 54 werden durch an den Teilen 52, 53 befindliche kegelstumpfförmige Ansätze 55, die unter Einhaltung eines Abstandes in kegelstumpfförmige Ausnehmungen 56 der benachbarten Teile eingreifen, gebildet. Der die Sollbruchstellendicke bestimmende Abstand kann beispielsweise durch an den Stirnseiten der Ansätze 55 angebrachte, nicht dargestellte Nocken oder während des Herstellungsprozesses durch das Spritzwerkzeug erzeugt werden. An den kegelstumpfförmigen Ansätzen 55 und in den kegelstumpfförmigen Ausnehmungen 56 sind Halterillen 57 bzw. 58 vorgesehen. Die Teile 51, 52 und 53 sind an den Sollbruchstellen 54 mittels eines Kunststoffes miteinander verbunden, wobei die Halterillen 57, 58 der Verankerung dienen. Die am ersten, vordersten Teil 51 angeordnete Geschossspitze 50 weist einen Zapfen 59 auf, der in eine mit Halterillen 61 versehene Bohrung 60 des ersten, vordersten Teiles 51 eingreift. Im dritten, hintersten Teil 53 ist eine Bohrung 62 vorgesehen, in welcher ein Leuchtspursatz 63 untergebracht ist. 4 , the shattering penetrator 2 consists of a projectile tip 50 and a first, second and third part 51 , 52 and 53. Between the parts 51, 52, 53 predetermined breaking points 54 are provided. The predetermined breaking points 54 are formed by frustoconical lugs 55 located on the parts 52 , 53 , which engage in a frustoconical recesses 56 of the adjacent parts while maintaining a distance. The distance determining the predetermined breaking point thickness can be generated, for example, by cams (not shown) attached to the end faces of the projections 55 or by the injection mold during the production process. Retaining grooves 57 and 58 are provided on the frustoconical lugs 55 and in the frustoconical recesses 56 . The parts 51 , 52 and 53 are connected to one another at the predetermined breaking points 54 by means of a plastic, the retaining grooves 57 , 58 serving for anchoring. The projectile tip 50 arranged on the first, foremost part 51 has a pin 59 which engages in a bore 60 of the first, foremost part 51 provided with retaining grooves 61 . In the third, rearmost part 53 , a bore 62 is provided, in which a tracer 63 is accommodated.

Der Zerschellpenetrator gemäss Fig. 5 weist gegenüber dem anhand der Fig. 4 beschriebenen Zerschellpenetrator drei anders gestaltete Teile 71, 72, 73 und Sollbruchstellen 74 auf. Die Sollbruchstellen 74 werden durch an den Teilen 71 und 72 befindliche Zapfen 75, die unter Einhaltung eines Abstandes in Bohrungen 76 der benachbarten Teile eingreifen, gebildet. Hierbei ist das Verhältnis Zapfendurchmesser zu Zapfenlänge wesentlich kleiner als das Verhältnis Ansatzdurchmesser zu Ansatzlänge gemäss den Ausführungen nach Fig. 1, 2 und 3. Der Abstand bzw. die Sollbruchstellendicke kann, wie bereits vorstehend beschrieben, erzeugt werden. An den Zapfen 75 und in den Bohrungen 76 sind Halterillen 77 bzw. 78 angeordnet. Die Kanten der Zapfen 75 und Bohrungen 76 sind beispielsweise abgeschrägt, wobei sie jedoch auch rund oder scharfkantig sein können. Im dritten, hintersten Teil 73 ist eine Bohrung 79 vorgesehen, in welcher ein Leuchtspursatz 80 untergebracht ist. 5 has three differently designed parts 71 , 72 , 73 and predetermined breaking points 74 compared to the crushing penetrator described with reference to FIG. 4 . The predetermined breaking points 74 are formed by pins 75 located on the parts 71 and 72 , which engage in bores 76 of the adjacent parts while maintaining a distance. The ratio of the pin diameter to the pin length is considerably smaller than the ratio of the shoulder diameter to the shoulder length according to the explanations according to FIGS . 1 , 2 and 3 . The distance or the predetermined breaking point thickness can be generated as already described above. Retaining grooves 77 and 78 are arranged on the pins 75 and in the bores 76 . The edges of the pins 75 and bores 76 are chamfered, for example, although they can also be round or sharp-edged. In the third, rearmost part 73 , a bore 79 is provided, in which a tracer set 80 is accommodated.

In der Fig. 6 ist mit 86 ein an den Teilen 71, 72 vorgesehener Zapfen bezeichnet, an dem ein scheibenförmiger Ansatz 85 angeordnet ist. Der scheibenförmige Ansatz 85 verhindert, dass bei der Herstellung des Zerschellpenetrators Kunststoff zwischen einen Teil der Bohrungen 76 und die Zapfen 86 der Teile 71, 72 eindringen kann. Der Zapfen 86 hat einen wesentlich kleineren Durchmesser als der Zapfen 75 gemäss der Ausführung nach Fig. 5, so dass ein relativ grosser Freiraum entsteht und der Zerschellpenetrator bei Erreichen des Zieles leichter zerbrechen kann.In FIG. 6 , 86 denotes a pin provided on the parts 71 , 72 , on which a disk-shaped extension 85 is arranged. The disk-shaped extension 85 prevents plastic from penetrating between part of the bores 76 and the pins 86 of the parts 71 , 72 during the manufacture of the shattering penetrator. The pin 86 has a significantly smaller diameter than the pin 75 according to the embodiment according to FIG. 5 , so that a relatively large free space is created and the smashing penetrator can break more easily when the target is reached.

Nach Fig. 7 sind an den kegelstumpfförmigen Ansätzen 55 der Teile 52, 53 Ringe 65 vorgesehen, mit welchen der Abstand zwischen den Teilen, 51, 52, 53 bzw. die Sollbruchstellendicke eingestellt werden kann. Wie nach der Ausführung gemäss Fig. 6 wird hierdurch ein nicht mit Kunststoff gefüllter Freiraum gebildet.According to FIG. 7 , rings 65 are provided on the frustoconical projections 55 of the parts 52 , 53 , with which rings the distance between the parts 51 , 52 , 53 and the predetermined breaking point thickness can be set. As in the embodiment according to FIG. 6 , this creates a free space not filled with plastic.

Gemäss Fig. 7a weisen die kegelstumpfförmigen Ansätze 55 Ringe 66 auf, mittels welchen ähnlich wie in Fig. 7 der Abstand zwischen den Teilen 51, 52, 53 bzw. die Sollbruchstellendicke eingestellt werden kann. Die Ansätze 55 ragen in kegelstumpfförmige Ausnehmungen 67 hinein, die länger als die Ansätze 55 sind, wobei ebenfalls ein nicht mit Kunststoff gefüllter Freiraum gebildet wird.According to FIG. 7a , the frustoconical projections 55 have rings 66 , by means of which the distance between the parts 51 , 52 , 53 and the predetermined breaking point thickness can be set, similarly to FIG. 7 . The lugs 55 protrude into frustoconical recesses 67 which are longer than the lugs 55 , a free space not being filled with plastic also being formed.

Die anhand der Fig. 1 bis 7 vorstehend beschriebenen Teile 21 bis 24, 51, 52, 53 und 71, 72, 73 bestehen beispielsweise aus Stahl, können jedoch auch aus Messing, Bronze oder mit Bronzepulver oder -spänen bzw. Wolframpulver gefülltem Kunststoff sein. Der für die Geschossspitzen 20, 50 und die Sollbruchstellen 25, 54 und 74 verwendete Kunststoff ist vorzugsweise ein hochwarmfester, , faserverstärkter, thermoplastischer Kunststoff.The parts 21 to 24 , 51 , 52 , 53 and 71 , 72 , 73 described above with reference to FIGS. 1 to 7 consist for example of steel, but can also be made of brass, bronze or plastic filled with bronze powder or chips or tungsten powder . The plastic used for the projectile tips 20 , 50 and the predetermined breaking points 25 , 54 and 74 is preferably a high-temperature, fiber-reinforced, thermoplastic.

Die Stirnwände der Teile, welche die Sollbruchstellen 25, 54 und 74 begrenzen, müssen nicht wie dargestellt parallel sein, sondern können schräg zueinander verlaufen, so dass die Sollbruchstellen zwischen der Umfangsfläche des Zerschellpenetrators 2 und den Ansätzen 26, 55 bzw. Zapfen 75 und den Ausnehmungen 27, 56 bzw. Bohrungen 76 beispielsweise einen V-förmigen Querschnitt aufweisen können. The end walls of the parts which delimit the predetermined breaking points 25 , 54 and 74 do not have to be parallel, as shown, but can run obliquely to one another, so that the predetermined breaking points between the peripheral surface of the smashing penetrator 2 and the shoulders 26 , 55 or pin 75 and the Recesses 27 , 56 or bores 76 can have a V-shaped cross section, for example.

Es liegt auch im Rahmen der Erfindung, dass der Zerschellpenetrator 2 anstatt aus vier Teilen (Fig. 1 bis 3) bzw. drei Teilen (Fig. 4 und 5) auch aus mehr oder weniger (mindestens jedoch zwei) Teilen bestehen kann.It is also within the scope of the invention that the shattering penetrator 2 can also consist of more or less (at least two) parts instead of four parts ( FIGS. 1 to 3 ) or three parts ( FIGS. 4 and 5 ).

Die Ansätze 55 und Ausnehmungen 56 (Fig. 4, 7 und 7a) können anstatt kegelstumpfförmig auch kegelförmig ausgebildet sein. The lugs 55 and recesses 56 ( FIGS. 4 , 7 and 7a ) can also be conical instead of frustoconical.
