Description

Die vorliegende Erfindung betrifft ein Übungsgeschoß mit einer aus Kunststoff bestehenden Geschoßhülse mit spitzbogenförmigem Kopfteil und einer die Geschoßhülse bei einem Aufprall von innen heraus zerstörenden und nach Ballistik und Schwerpunktlage die Geschoßmasse simulierenden Füllung.The present invention relates to a training projectile with a projectile casing made of plastic with an ogival head part and a bullet casing that destroys the bullet from the inside out in the event of an impact and the filling simulating the projectile mass according to ballistics and center of gravity.

Ein Übungsgeschoß der gattungsgemäßen Art ist aus dem DE-GM 18 57 880 bekanntA training projectile of the generic type is known from DE-GM 18 57 880

Bei dem Übungsgeschoß gemäß dem DE-GM 18 57 880 ist die Geschoßhülse mit einer Zerlegerladung, mit Metallpulver-Preßlingen und einer Beobachtungsladung gefüllt. Im Falle eines Aufpralles wird durch die Zündung der Zerlegerladung die Geschoßhülse von innen heraus zerstört.In the practice projectile according to DE-GM 18 57 880, the projectile case is with a decomposing charge, filled with metal powder compacts and an observation charge. In the event of an impact it will when the decomposing charge was ignited, the shell case was destroyed from the inside out.

Ein Übungsgeschoß der bekannten Art muß also notwendigerweise eine Zerlegerladung mit einem entsprechenden Aufschlagzünder aufweisen und ist demzufolge kostenaufwendig in seiner Herstellung. Außerdem besteht bei einem derartigen Übungsgeschoß die Gefahr, daß bei unsachgemäßem Transport die Zerlegerladung gezündet wird.A training projectile of the known type must therefore necessarily have a dismantling charge with a corresponding one Have percussion fuse and is therefore expensive to manufacture. In addition, there is with such a training projectile there is a risk that, in the event of improper transport, the dismantling charge is ignited.

Aus der DE-AS 23 09 589 ist ein Übungsgeschoß für Schußwaffen bekannt, bei dem die Geschoßhülse aus Metall besteht. Diese Geschoßhülse ist mit einer verdichteten, mit einem polymerisierbaren Produkt vermischten Füllpulvermasse gefüllt und mit einer Sollbruchstelle versehen, die als radial angeordneter, verjüngter Bruchbereich ausgebildet ist.From DE-AS 23 09 589 a training projectile for firearms is known in which the projectile case from Made of metal. This bullet case is mixed with a compacted, with a polymerizable product Filling powder compound filled and provided with a predetermined breaking point, which is tapered as a radially arranged Break area is formed.

Bei einem derartigen Übungsgeschoß müssen, um die Geschoßhülse zu zerstören, derart hohe Kräfte auftreten, daß die metallische Geschoßhülse gesprengt wird. Durch die Vorsehung einer Sollbruchstelle soll nun zwar erreicht werden, daß die Geschoßhülse im Falle eines Aufschlages, selbst wenn dieser unter schrägem Auftreffwinkel erfolgt und/oder bei geringer Geschwindigkeit stattfindet, das Geschoß in Bruchstücke geringer Masse zerbricht, es ist aber nicht sichergestellt, daß ein derartiges Übungsgeschoß im Falle einer geringen Ablenkung von seiner vorgegebenen Flugbahn zerstört wird, so daß die Gefahr von Querschlägern nicht auszuschließen ist.With such a training projectile, in order to destroy the projectile case, such high forces must occur, that the metallic bullet casing is blown. By providing a predetermined breaking point should now it can be achieved that the projectile case in the event of an impact, even if this is oblique The angle of impact takes place and / or takes place at low speed, the projectile in fragments is lower Mass breaks, but it is not guaranteed that such a training projectile in the event of a slight deflection is destroyed by its predetermined trajectory, so that the risk of ricochets cannot be ruled out is.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Übungsgeschoß der gattungsgemäßen Art so zu gestalten, daß mittels einer einfachen und kostengünstigen Füllung ein sicheres Zerstören beim Aufprall ohne Zerlegerladung erzielt wird.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Füllung aus symmetrisch in der Hülse aneinanderliegenden Metallscheiben 25, 37 besteht. Durch die Verwendung von Metallscheiben zur Füllung der Geschoßhülse wird einerseits erreicht, daß die Hcrsicllkosten für das Übungsgeschoß äußerst gering sind, da sich derartige Metallscheiben in einfachen Fcrtigungspmzessen herstellen lassen. Andererseits wird sichergestellt, daß das Übungsgeschoß im Falle eines Aufpralles oder auch im Falle nur geringfügiger Ablenkung von seiner vorgegebenen Flugbahn sicher zerstört wird, da in einem derartigen Falle der Gleichgewichtszustand der durch die Beschleunigung beim Abschießen blockartig zusammengehaltenen Metallscheiben gestört und die Metallscheiben aufgrund der wirksam werdenden Zentrifugalkräfte die Zerstörung der Geschoßhülse und dais Auseinanderfallen des gesamten Geschosses bewirken.
The present invention is based on the object of designing a training projectile of the generic type in such a way that, by means of a simple and inexpensive filling, reliable destruction on impact is achieved without a decomposing charge.
According to the invention, this object is achieved in that the filling consists of metal disks 25, 37 lying symmetrically against one another in the sleeve. By using metal disks to fill the projectile case, it is achieved on the one hand that the costs for the training projectile are extremely low, since such metal disks can be produced in simple manufacturing processes. On the other hand, it is ensured that the training projectile is safely destroyed in the event of an impact or even in the event of only slight deflection from its predetermined trajectory, since in such a case the state of equilibrium of the metal disks held together in blocks by the acceleration during firing is disturbed and the metal disks due to the becoming effective Centrifugal forces destroy the shell and cause the entire projectile to fall apart.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of subclaims.

weiteren Ausführungsform eines Übungsgeschosses gemäß der Erfindung.Another embodiment of a training bullet according to the invention.

In der Zeichnung ist ein zerbrechliches Übungsgeschoß 13 aus Kunststoff gezeigt, das vorzugsweise aus einem thermoplastischen Material besteht und ein Geschoßführungsband 15 aus dem gleichen Material aufweist, das den Geschoßkörper umgibt. Das thermoplastische Material, aus dem das Übungsgeschoß 13 hergestellt ist, kann Polyäthylen, glasgefülltes Nylon, hartes Polyvinylchlorid od. dgl. sein. Die Verwendung dieser Materialien mit verschiedenen spezifischen Gewichten macht es möglich, das Trägheitsmoment, das Gewicht und Schwerpunktzentrum des Geschosses zu variieren, indem das Volumen und die Abmessungen der Kunststoffteile entsprechend ausgewählt werden und dementsprechend die Proportionen dieser Teile zum Gesamtvolumen und den Gesamtabmessungen des Übungsgeschosses 13 angepaßt werden, um die Anpassung an die jeweiligen spezifischen ballistischen Forderungen zu erreichen. In the drawing, a fragile training projectile 13 made of plastic is shown, which is preferably made of consists of a thermoplastic material and has a projectile guide band 15 made of the same material, surrounding the projectile body. The thermoplastic material from which the training bullet 13 is made is, polyethylene, glass-filled nylon, hard polyvinyl chloride or the like. Be. Using this Materials with different specific weights make it possible to adjust the moment of inertia, the weight and center of gravity of the projectile to vary by changing the volume and dimensions of the plastic parts be selected accordingly and accordingly the proportions of these parts to the total volume and the overall dimensions of the training projectile 13 can be adapted to the adaptation to the to achieve respective specific ballistic requirements.

Wie aus Fig.2 ersichtlich ist, beinhaltet eine Geschoßhülse 19 ein spitzbogenförmiges Kopfstück 21 sowie einen länglichen stangenartigen Zentralabschnitt 23, der sich von dem Kopfstück nach hinten erstreckt. Das spitzbogenförmige Kopfstück 21 und der stangenähnliche Zentralabschnitt 23 werden vorzugsweise zusammen mit dem Geschoßführungsband 15 einstückig miteinander aus Kunststoff hergestellt. Eine Reihe von Metallscheiben 25, die beispielsweise aus Stahl bestehen, haben mittig Öffnungen, die so dimensioniert sind, daß sie über den stangenartigen Zentralabschnitt 23 der Geschoßhülse 19 gleiten können. Die Anzahl und die Größe der Metallscheiben 25 kann variiert werden, um dadurch das Gesamtgewicht und die Lage des Schwer-As can be seen from Figure 2, includes a bullet case 19 an ogival head piece 21 and an elongated rod-like central section 23 extending rearward from the headpiece. The ogival head piece 21 and the rod-like one Central section 23 are preferably made in one piece together with projectile guide band 15 made of plastic together. A series of metal disks 25, for example made of steel, have central openings which are dimensioned so that they over the rod-like central portion 23 of the Bullet sleeve 19 can slide. The number and size of the metal disks 25 can be varied in order to thereby the total weight and the position of the heavy

punlctzentrums des Ühungsgeschosses 13 zu steuern, um noch mehr die Bedingungen des wirklichen Schießeas mit richtiger Munition zu simulieren. Nachdem die Metallscheiben 25 angeordnet sind, wird eine Druckplatte 27 aus Stahl in die öffnung der GeschoßhüJse 19 eingesetzt derart, daß sich der Ansatz 29 der Druckplatte 27 am rückwärtigen Ende des Zentralabschnittes 23 abstützt Eine Verschlußkappe 31 aus Kunststoff wird mittels Ultraschall in den offenen Boden der Gesrhoßhülse 19 eingeschweißt, um die Montage des Übungsgeschosses 13 zu vollenden. Durch derartiges Schweißen wird einziges integrales Stück gebildet, dessen innen befindlichen Teile vollständig nach außen abgedichtet liegen.point center of the training floor 13 to control even more the conditions of the real shooting range to simulate with real ammunition. After the metal disks 25 are arranged, a pressure plate becomes 27 made of steel inserted into the opening of the projectile case 19 in such a way that the projection 29 of the pressure plate 27 is supported on the rear end of the central section 23. A closure cap 31 made of plastic is by means of ultrasound into the open bottom of the joint sleeve 19 welded in to facilitate the assembly of the training bullet 13 to complete. Such welding forms a single integral piece, its inside located parts are completely sealed to the outside.

Für Waffen kleineren Kalibers ist beispielsweise das in F i g. 3 dargestellte Ausführungsbeispiel noch geeigneter. Bei dieser Ausführungsform eines zerbrechlichen Übungsgeschosses 13 beinhaltet eine Geschoßhülse 33 ein spitzbogenförmiges Kopfteil 35, das das vordere Ende einer mittigen Öffnung 36 schiießt, in der eine Reihe von Metallscheiben 37 angeordnet sind. Diese Metallscheiben 37 dienen dem gleichen Zweck und haben die gleiche Funktion wie die Metallscheiben 25 im Ausführungsbeispiel nach F i g. 2.For weapons of smaller caliber, for example, that shown in FIG. 3 shown embodiment is even more suitable. In this embodiment of a frangible training projectile 13, a projectile casing 33 includes an ogival head portion 35 which closes the front end of a central opening 36 in which a series of metal disks 37 are arranged. These metal disks 37 serve the same purpose and have the same function as the metal disks 25 in the exemplary embodiment according to FIG. 2.

Es ist hervorzuheben, daß, obwohl das Übungsgeschoß 13 mit einem integralen Teil und Körperbereich dargestellt wurde, es auch mit einem separaten spitzbogenförmigen Kopfteil 35 und einer integralen Verschlußkappe hergestellt werden könnte. Bei dieser letzteren Ausgestaltung würden die Metallscheiben 37 dann von der Vorderseite des Übungsgeschosses aus eingebracht und das spitzbogenförmige Kopfteil 35 könnte dann mittels Ultraschall nach dem Zusammenbau angeschweißt werden. Ferner können die Metallscheiben 37 jede geeignete Form haben, solange sie symmetrisch bleiben und das erforderliche Gewicht sowie die gewünschten, die Schwerpunktslage betreffenden Eigenschaften des Übungsgeschosses gewährleisten. Die Metallscheiben 37 könnten beispielsweise eine genutete Umfangsfläche haben, so daß das Gewicht noch wirksamer verteilt werden könnte.It should be emphasized that although the training floor 13 has an integral part and body area has been shown, it also has a separate ogival head portion 35 and an integral closure cap could be made. In this latter embodiment, the metal disks 37 would then brought in from the front of the training bullet and the ogival head part 35 could then ultrasonically welded on after assembly. Furthermore, the metal disks 37 have any suitable shape as long as they remain symmetrical and have the required weight as well as the desired, ensure the properties of the training floor relating to the center of gravity. The metal disks 37 could for example have a grooved peripheral surface, making the weight even more effective could be distributed.

Wenn das Übungsgeschoß während der Übung auf einem Schießgelände auf ein Ziel abgefeuert wird, zerbricht die Geschoßhülse 19 beim Aufprall, so daß das Übungsgeschoß 13 unmittelbar danach auseinanderfäilt. Da das Übungsgeschoß 13 unmittelbar bei Berührung mit dem Ziel zerbricht, sind die gefährlichen Zufälligkeiten weitfliegender Querschläger oder Abpraller vollständig ausgeschaltet, und die Größe und Lage eines solchen Übungsgeländes wird sehr viel weniger kritisch als bisher.If the training bullet is fired at a target during a practice at a firing range, it will break the projectile casing 19 on impact, so that the training projectile 13 falls apart immediately thereafter. Since the training projectile 13 breaks immediately on contact with the target, the dangerous coincidences high-flying ricochets or ricochets completely eliminated, and the size and location of one Such a training ground will be much less critical than before.

Das Übungsgeschoß gemäß der Erfindung ist mit thermoplastischen Geschoßhülsen 19 und 33 versehen, die auch als Windschutz dienen und den aerodynamischen Luftwiderstand des Übungsgeschosses reduzieren und somit den Energieverlust während des Fluges /um Ziel auf ein Minimum herabsetzen. Das Geschoßführungsband 15 aus Kunststoff umgibt die Geschoßhülse 19 und ist mit dieser integral. Das Geschoßführungsband 15 wirkt mit dem Zug im gezogenen Lauf der Feuerwaffe zusammen und setzt dabei in erheblichem Maße die Reibung des Geschoßkörpers herab, wenn dieser durch die Laufbohrung getrieben wird, wodurch die Effizienz der Arbeitsweise der Feuerwaffe beträchtlich verbessert wird.The training projectile according to the invention is provided with thermoplastic projectile sleeves 19 and 33 , which also serve as wind protection and reduce the aerodynamic drag of the training projectile and thus reduce the energy loss during the flight / around the target to a minimum. The projectile guide band 15 made of plastic surrounds the projectile casing 19 and is integral therewith. The projectile guide band 15 cooperates with the train in the rifled barrel of the firearm and thereby significantly reduces the friction of the projectile body when it is driven through the barrel bore, whereby the efficiency of the operation of the firearm is considerably improved.

Es ist somit ersichtlich, daß vorstehend ein Übungsgeschoß beschrieben wurde, das in der Benutzung einfach ist, !eichst hergestellt werden kann und mit größter Sicherheit eingesetzt werden kann, auch auf einem Schießgelände, welches nahe an bewohnten Gebieten HegtIt can thus be seen that a training bullet has been described which is simple to use is,! calibrated can be manufactured and can be used with the greatest security, even on a Firing range, which is close to inhabited areas
