Description

Die Erfindung betrifft eine Patrone, die aus einer Patronenhülse und einer Geschossanordnung besteht, welche über einen Hülsendeckel mit der Patronenhülse verbunden ist.The invention relates to a cartridge which consists of a cartridge case and a projectile assembly which is connected via a sleeve cover with the cartridge case.

Eine derartige Patrone ist beispielsweise aus der DE 27 47 313 C2 bekannt. Dabei umfasst die bekannte Geschossanordnung ein Pfeilgeschoss mit einem unterkalibrigen Geschosskörper und einem heckseitig an dem Geschosskörper angeordneten Kegel-Leitwerk, wobei zwischen dem Schwerpunkt des Geschosskörpers und der Geschossspitze ein mit dem Pfeilgeschoss segmentierter Einflansch-Treibkäfig mit sich nach außen erstreckenden Wandbereichen reib- und/oder formschlüssig verbunden ist.Such a cartridge is for example from the DE 27 47 313 C2 known. In this case, the known projectile arrangement includes a shotgun with a subcaliber projectile body and a rear side of the projectile body cone-tail, wherein between the center of gravity of the projectile body and the projectile nose a segmented with the arrow floor Einflansch-sabot with outwardly extending wall areas rubbing and / or is positively connected.

Um bei Verwendung eines derartigen Einflansch-Treibkäfigs im Waffenrohr eine gute Zentrierung des gesamten Geschosses zu erhalten, wird in der DE 27 47 313 C2 die Verwendung eines kalibergleichen Kegel-Leitwerkes vorgeschlagen, sodass das Geschoss sich im Waffenrohr heckseitig über das Leitwerk an der Innenwand des Waffenrohres abstützen kann. Allerdings weisen derartige Geschosse den Nachteil auf, dass die Kegel-Leitwerke, insbesondere wenn sie aus großkalibrigen Waffen verschossen werden sollen, sehr kostenaufwendig sind und ein hohes Gewicht besitzen.In order to obtain a good centering of the entire projectile when using such a flange sabot in the barrel, is in the DE 27 47 313 C2 proposed the use of a caliber-identical cone tail, so that the projectile can be supported in the gun barrel at the rear over the tail on the inner wall of the gun barrel. However, such projectiles have the disadvantage that the cone-tail, especially if they are to be fired from large-caliber weapons are very expensive and have a high weight.

Sofern Pfeilgeschosse mit einem unterkalibrigen Leitwerk verwendet werden sollen, schlägt die DE 27 47 313 C2 die Verwendung von Zweiflansch-Treibkäfigen vor, wie sie beispielsweise aus der DE-PS 17 03 507 bekannt sind. Derartige Treibkäfige weisen allerdings ebenfalls ein hohes Gewicht auf und sind sehr kostenaufwendig.If the projectiles are to be used with a subcaliber tail, the DE 27 47 313 C2 the use of two-flange sabots, as for example from the DE-PS 17 03 507 are known. However, such sabots also have a high weight and are very expensive.

Aus der DE 39 37 665 A1 sind Patronen bekannt, deren Geschossanordnungen aus Pfeilgeschossen mit unterkalibrigen Leitwerken sowie Einflansch-Treibkäfigen bestehen. Dabei dienen zur Zentrierung und Abstützung der Geschossanordnungen im jeweiligen Waffenrohr mehrere zusätzliche Stützstreben, die gleichmäßig über den Umfang der rückwärtigen Endbereiche der Treibkäfige verteilt angeordnet sind.From the DE 39 37 665 A1 Cartridges are known whose bullet arrays consist of shotgun bullets with sub-caliber tails and single-flange sabots. It serve to center and support the bullet assemblies in each gun barrel a plurality of additional support struts which are distributed uniformly over the circumference of the rear end portions of the sabots.

Der Erfindung liegt die Aufgabe zugrunde, eine Patrone der eingangs erwähnten Art anzugeben, deren Geschossanordnung kostengünstiger herstellbar ist als vergleichbare Anordnungen.The invention has for its object to provide a cartridge of the type mentioned, whose bullet assembly is less expensive to produce than comparable arrangements.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

Die Erfindung beruht im Wesentlichen auf dem Gedanken, mit dem Hülsendeckel geschossseitig eine das Leitwerk des Pfeilgeschosses zentrierende und beim Abschuss der Patrone von dem Leitwerk abtrennbare Aufnahmeeinrichtung zu verbinden, welche einen ringförmigen Heckflansch umfasst, dessen Außendurchmesser dem Geschosskaliber der jeweiligen Patrone entspricht.The invention is based essentially on the idea to connect with the sleeve cover on the projectile side a centering of the tail of the arrow centering and detachable during firing of the cartridge from the tail receiving device which comprises an annular rear flange whose outer diameter corresponds to the bullet caliber of each cartridge.

Vorzugsweise besteht die Aufnahmeeinrichtung aus Kunststoff.Preferably, the receiving device consists of plastic.

Bei einer bevorzugten Ausführungsform der Erfindung, bei der das Pfeilgeschoss ein Kegelleitwerk besitzt, weist die Aufnahmeeinrichtung ein das Leitwerk umfassendes kegelförmiges Vorderteil auf, welches treibkäfigseitig vor dem Heckflansch angeordnet ist und mindestens in einem Teilbereich des Leitwerkes an diesem formschlüssig anliegt. Dabei kann die Außenseite des kegelförmigen Vorderteiles der Aufnahmeeinrichtung über mehrere, gleichmäßig über den Umfang verteilt angeordnete, rippenförmige Streben mit dem Heckflansch verbunden sein.In a preferred embodiment of the invention, in which the arrowed floor has a conical structure, the receiving device has a conical front part which comprises the tail unit, which is arranged in front of the rear flange on the friction cage side and engages in a form-fitting manner at least in a partial area of the tail unit. In this case, the outer side of the conical front part of the receiving device can be connected to the rear flange via a plurality of rib-shaped struts distributed uniformly over the circumference.

Der Einflansch-Treibkäfig kann vorzugsweise als Gasdruckaufnahmeflächen ein sich an die radialen Wandbereiche heckseitig anschließendes konusförmiges Heckteil aufweisen, dessen heckseitiges Ende aber noch vor dem Schwerpunkt des Pfeilgeschosses angeordnet ist.The one-flange sabot may preferably have as gas pressure-receiving surfaces on the radial wall areas at the rear subsequent conical rear part, the rear-end but is still located in front of the center of gravity of the arrowhead.

Die Treibkäfigsegmente können aus Stahl oder einem Leichtmetall bestehen.The sabot segments may be made of steel or a light metal.

Die zwischen den Treibkäfigsegmenten heckseitig gebildeten Trennfugen sind vorzugsweise durch eine Vulkanisatschicht gasdicht verschlossen.The separating joints formed on the rear side between the sabot segments are preferably closed gas-tight by a vulcanizate layer.

Um bei der Bewegung der Geschossanordnung nach Schussabgabe sicher zu vermeiden, dass Treibladungsgase rohrwandseitig an der Geschossanordnung vorbeiströmen, hat es sich als vorteilhaft erwiesen, wenn der radiale Wandbereich des Treibkäfigs an seinem dem Pfeilgeschoss abgewandten Ende heckseitig mit einer Dichtlippe, vorzugsweise aus Gummi, versehen ist.In order to reliably avoid the propellant charge gases passing tube wall side of the projectile assembly in the movement of the projectile assembly, it has proved to be advantageous if the radial wall portion of the sabot at its end facing away from the arrowhead end is provided at the rear with a sealing lip, preferably made of rubber ,

Um außerdem die Patrone laden zu können, ohne dass das üblicherweise an dem Treibkäfig am äußeren Umfang befestigte Führungs- und Dichtungsband den Ladevorgang behindert, sind die radialen Wandbereiche des Treibkäfigs außenseitig mit einer Ausnehmung versehen, in welcher vorderseitig ein keilförmiger Segmentring mit einer dem segmentierten Treibkäfig entsprechenden Teilung und heckseitig ein sich an den Segmentring anschließendes umlaufendes Führungs- und Dichtungsband eingelegt sind, wobei das Führungs- und Dichtungsband mindestens den ihm zugewandten keilförmigen Bereich des Segmentringes überdeckt, und wobei der Segmentring und das Führungs- und Dichtungsband derart gewählt sind, dass in der Ruheposition der Geschossanordnung der Außendurchmesser des Führungs- und Dichtungsbandes kleiner oder gleich dem Geschosskaliber ist und beim Abschuss der Geschossanordnung der keilförmige Bereich des Segmentringes das Führungs- und Dichtungsband nach außen drückt.In addition, in order to load the cartridge without the usually attached to the sabot at the outer periphery guide and sealing tape obstructs the loading process, the radial wall portions of the sabot are provided on the outside with a recess in which the front side a wedge-shaped segment ring with a segmented sabot The guide and sealing strip covers at least the wedge-shaped region of the segment ring facing it, and wherein the segment ring and the guide and sealing strip are selected such that in the rest position of the projectile arrangement of the outer diameter of the guide and sealing strip is smaller than or equal to the bullet caliber and the wedge-shaped portion of the segment ring presses the guide and sealing strip to the outside when firing the bullet assembly.

Der Segmentring kann dabei aus Metall und das Führungs- und Dichtungsband kann aus einem geeigneten Kunststoff bestehen.The segment ring can be made of metal and the guide and sealing strip can be made of a suitable plastic.

Als vorteilhaft hat es sich erwiesen, wenn die radialen Wandbereiche des Treibkäfigs sowohl vorder- wie heckseitig mit taschenförmigen Vertiefungen versehen sind, so dass die Treibkäfigsegmente durch die auf sie wirkenden vorderseitigen Luft-Staudruckkräfte und heckseitigen Treibladungsgaskräfte sich etwa parallel zu dem Geschosskörper von diesem radial abheben, wenn die Geschossanordnung das entsprechende Waffenrohr mündungsseitig passiert hat.It has proved to be advantageous if the radial wall areas of the sabot are provided with pocket-like depressions both on the front and rear sides, so that the sabot segments are radially offset from the projectile body by the front air pressure forces and rear propellant charge gas forces acting on them when the projectile arrangement has passed the corresponding weapon barrel mouth side.

Mit der vorliegenden Konstruktion wird sichergestellt, dass nach Abschuss eine genaue Führung des Pfeilgeschosses in dem entsprechenden Waffenrohr realisiert wird. Neben dem Kostengesichtspunkt wird auch die Problematik der Gewichtsgesichtspunkte berücksichtig und die Schnittstelle beispielsweise für eine 120 mm Munition beachtet. Leitwerk und Geschosskörper können aus zwei Teilen bestehen, aber auch aus einem Teil hergestellt werden. Für die Werkstoffauswahl gilt dabei, dass neben den Kräften im Abschussfall auch die Schwerpunktslage des Fluggeschosses zu berücksichtigen ist. So reduziert beispielsweise ein Leitwerk aus (leichtem) Aluminium durch sein leichtes Gewicht die Zug- Spannung im übertragenden Querschnitt des Geschosskörpers, schiebt aber den Schwerpunkt des Fluggeschosses weiter nach vorne.With the present construction it is ensured that after firing an accurate guidance of the arrow bullet is realized in the corresponding barrel. In addition to the cost aspect, the problem of weight considerations is taken into account and the interface is considered, for example, for a 120 mm ammunition. Tail and projectile body can consist of two parts, but also made of one part become. For the selection of materials, it applies that in addition to the forces in the event of firing, the center of gravity of the projectile must also be taken into account. For example, a tail unit made of (light) aluminum reduces the tensile stress in the transmitting cross-section of the projectile body due to its light weight, but pushes the center of gravity of the projectile further forward.

In Fig.1 ist mit 1 eine Patrone bezeichnet, die im Wesentlichen aus einer Patronenhülse 2 und einer Geschossanordnung 3 besteht, welche über einen Hülsendeckel 4 mit der Patronenhülse 2 verbunden ist. Dabei ist in Fig.1 lediglich der dem Hülsendeckel 4 zugewandte Endabschnitt der Patronenhülse 2 angedeutet.In Fig.1 1 is a cartridge, which consists essentially of a cartridge case 2 and a projectile assembly 3, which is connected via a sleeve cover 4 with the cartridge case 2. It is in Fig.1 only the sleeve cover 4 facing end portion of the cartridge case 2 indicated.

Die Geschossanordnung 3 umfasst ein Pfeilgeschoss 5 mit einem unterkalibrigen Geschosskörper 6 und einem heckseitig an dem Geschosskörper 6 angeordneten unterkalibrigen Kegel-Leitwerk 7. Bei dem dargestellten Pfeilgeschoss 5 handelt es sich um ein Übungsgeschoss, dessen Geschosskörper 6 aus Stahl und dessen Leitwerk 7 zum Beispiel aus einer Aluminiumlegierung besteht.The projectile arrangement 3 comprises a projectile 5 with a subcaliber projectile body 6 and a rear side arranged on the projectile body 6 sub-caliber cone tail 7. The illustrated arrowhead 5 is a practice projectile, the projectile body 6 made of steel and its tail 7, for example an aluminum alloy.

Zwischen dem mit 8 bezeichneten Schwerpunkt des Geschosskörpers 6 und der Geschossspitze 9 des Pfeilgeschosses 5 ist ein durch Längsteilung segmentierter Einflansch-Treibkäfig 10 befestigt, wobei die Kraftübertragung zwischen dem Treibkäfig 10 und dem Geschosskörper 6 reibschlüssig mittels eines Kegelsitzes 11 erfolgt.Between the 8 designated center of gravity of the projectile body 6 and the projectile nose 9 of the arrow projectile 5 a segmented by longitudinal division Einflansch-sabot 10 is fixed, the power transmission between the sabot 10 and the projectile body 6 is frictionally by means of a conical seat 11.

Der Einflansch-Treibkäfig 10 besteht aus drei gleichartigen Treibkäfigsegmenten 12-14 (Fig.2), die jeweils in Umfangsrichtung einen Winkel von 120° überdecken und vorzugsweise aus Stahl bestehen.The single flange sabot 10 consists of three similar sabot segments 12-14 (FIG. Fig.2 ), each covering an angle of 120 ° in the circumferential direction and preferably made of steel.

Der Einflansch-Treibkäfig 10 weist einen sich nach außen erstreckenden radialen Wandbereich 15 auf, über den sich das Pfeilgeschoss 5 an der inneren Oberfläche eines entsprechenden Waffenrohres (nicht dargestellt) abstützt. An den radialen Wandbereich 15 schließt sich heckseitig ein konusförmiges Heckteil 16 an, dessen heckseitige Ende 17 ebenfalls noch vor dem Schwerpunkt 8 des Pfeilgeschosses 5 angeordnet ist.The single flange sabot 10 has an outwardly extending radial wall portion 15 over which the arrowhead 5 is supported on the inner surface of a corresponding weapon barrel (not shown). At the radial wall portion 15, a conical rear part 16 adjoins the rear side, the rear end 17 of which is also arranged in front of the center of gravity 8 of the arrowhead 5.

Die zwischen den Treibkäfigsegmenten 12-14 heckseitig gebildeten Trennfugen 18-20 (Fig.2) sind gasdicht durch eine Vulkanisatschicht 21 (Fig.1) verschlossen.The rear side formed between the sabot segments 12-14 joints 18-20 ( Fig.2 ) are gastight through a Vulkanisatschicht 21 ( Fig.1 ) locked.

Außerdem ist der radiale Wandbereich 15 des Treibkäfigs 10 an seinem dem Pfeilgeschoss 5 abgewandten radialen Ende heckseitig mit einer umlaufenden Dichtlippe 22 aus Gummi versehen, um sicherzustellen, dass beim Abschuss der Geschossanordnung 3 in dem entsprechenden Waffenrohr keine Treibladungsgase zwischen der inneren Oberfläche des Waffenrohres und dem waffenrohrseitigen Ende des radialen Wandbereiches 15 des Treibkäfigs 10 hindurchströmen.In addition, the radial wall portion 15 of the sabot 10 at its end facing away from the arrowhead 5 radial end rear side provided with a circumferential sealing lip 22 made of rubber to ensure that when firing the projectile assembly 3 in the corresponding barrel no propellant gases between the inner surface of the gun barrel and the gun tube side end of the radial wall portion 15 of the sabot 10 flow therethrough.

Der radiale Wandbereich 15 des Treibkäfigs 10 ist außerdem außenseitig mit einer Ausnehmung 23 versehen, in welcher vorderseitig ein aus Metall bestehender keilförmiger Segmentring 24 mit einer dem segmentierten Treibkäfig 10 entsprechenden Teilung und heckseitig ein aus Kunststoff bestehendes umlaufendes Führungs- und Dichtungsband 25 eingelegt ist, welches den keilförmigen Segmentring 24 mindestens heckseitig überdeckt. Dabei sind der Segmentring 24 und das Führungs- und Dichtungsband 25 derart gewählt, dass in der in Fig.1 dargestellten Ruheposition der Geschossanordnung 3 der Außendurchmesser des Führungs- und Dichtungsbandes 25 kleiner oder gleich dem Geschosskaliber ist. Dadurch wird sichergestellt, dass das Führungs- und Dichtungsband 25 den Lade- oder Entladevorgang der Patrone 1 nicht behindert.The radial wall portion 15 of the sabot 10 is also provided on the outside with a recess 23 in which the front side of a metal wedge-shaped segment ring 24 with a segmented sabot 10 corresponding division and the rear side of a plastic existing circumferential guide and sealing tape 25 is inserted, which the wedge-shaped segment ring 24 at least covered on the rear side. In this case, the segment ring 24 and the guide and sealing strip 25 are selected such that in the in Fig.1 illustrated rest position of the projectile assembly 3, the outer diameter of the guide and sealing strip 25 is less than or equal to the bullet caliber. This ensures that the guide and sealing strip 25 does not hinder the loading or unloading process of the cartridge 1.

Hingegen werden beim Abschuss der Patrone 1 die Segmente des Segmentringes 24 mit ihren dem Führungs- und Dichtungsband 25 zugewandten keilförmigen Enden axial in Richtung zum Leitwerk 7 hin beschleunigt, und das Führungs- und Dichtungsband 25 weitet sich auf, so dass zusätzlich zu der durch die Dichtlippe 22 gewährleisteten Anfangsliderung eine weitere Dichtung gegen an der inneren Oberfläche des entsprechenden Waffenrohres entlang strömende Treibladungsgase erfolgt.By contrast, when the cartridge 1 is launched, the segments of the segment ring 24, with their wedge-shaped ends facing the guide and sealing band 25, are accelerated axially in the direction of the tail unit 7, and the guide and sealing band 25 widens on, so that in addition to the guaranteed by the sealing lip 22 Anfangsliderung another seal against against the inner surface of the corresponding gun barrel along flowing propellant gases takes place.

Der radiale Wandbereich 15 des Treibkäfigs 10 weist sowohl vorder- wie heckseitig taschenförmige Vertiefungen 26, 27 auf, so dass die Treibkäfigsegmente 12-14 durch die beim Abschuss der Patrone auf sie wirkenden vorderseitigen Luft-Staudruckkräfte als auch durch die auf sie wirkenden heckseitigen Treibladungsgaskräfte etwa parallel zu dem Geschosskörper 6 von diesem radial abheben, wenn die Geschossanordnung 3 die Mündung des entsprechenden Waffenrohres passiert hat.The radial wall portion 15 of the sabot 10 has pocket-like recesses 26, 27 on both the front and the rear sides, so that the sabot segments 12-14 are approximately of the front air ram forces acting upon launch of the cartridge as well as the rear propellant charge gas forces acting on them parallel to the projectile body 6 of this radially lift off when the projectile assembly 3 has passed the mouth of the corresponding barrel.

Mit dem Hülsendeckel 4 der Patrone 1 ist geschossseitig eine das Leitwerk 7 des Pfeilgeschosses 5 zentrierende und beim Abschuss der Patrone 1 von dem Leitwerk 7 abtrennbare Aufnahmeeinrichtung 28 verbunden. Die Aufnahmeeinrichtung 28 besteht vorzugsweise aus Kunststoff und umfasst einen ringförmigen Heckflansch 29, dessen Außendurchmesser dem Geschosskaliber der jeweiligen Patrone 1 entspricht. An den Heckflansch 29 schließt sich treibkäfigseitig ein das Kegel-Leitwerk 7 des Pfeilgeschosses 5 umfassendes kegelförmiges Vorderteil 30 an, welches in einem Teilbereich des Leitwerkes 7 an diesem formschlüssig anliegt.With the sleeve cover 4 of the cartridge 1 is on the projectile side a tail 7 of the arrow level 5 centering and detachable when shooting the cartridge 1 of the tail 7 receiving device 28 is connected. The receiving device 28 is preferably made of plastic and comprises an annular rear flange 29 whose outer diameter corresponds to the bullet caliber of the respective cartridge 1. On the rear flange 29 is followed by the drive cage side, a cone-tail 7 of the arrow level 5 comprehensive conical front part 30, which rests in a portion of the tail 7 at this form-fitting.

Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So können der Einflansch-Treibkäfig und das Pfeilgeschoss beispielsweise auch über eine Formschlussverbindung, etwa einem Rillenprofil oder einem Gewinde, miteinander verbunden sein. Ein entsprechendes Ausführungsbeispiel zeigen die Fig.3 und 4.Of course, the invention is not limited to the embodiment described above. For example, the flange sabot and the arrowhead can also be connected to one another via a form-locking connection, for example a groove profile or a thread. A corresponding embodiment show the Figure 3 and 4 ,

Dabei ist den Fig.3 und 4 eine Geschossanordnung 3' entnehmbar, bei welcher der Einflansch-Treibkäfig 10' über ein Rillenprofil 31 mit dem Geschosskörper 6' des Pfeilgeschosses 5' verbunden ist. Außerdem ist bei diesem Ausführungsbeispiel vorteilhafterweise vorgesehen, das die Außenseite des kegelförmigen Vorderteiles 30' der Aufnahmeeinrichtung 28' über mehrere, gleichmäßig über den Umfang verteilt angeordnete, rippenförmige Streben 32 mit dem Heckflansch 29' verbunden ist.It is the Figure 3 and 4 a projectile assembly 3 'can be removed, in which the one-flange sabot 10' is connected via a groove profile 31 with the projectile body 6 'of the arrow projectile 5'.
