Description

B E S C H R E I B U N G DESCRIPTION
Verfahren zur Herstellung einer Patrone und Patrone mit einem Treibkäfiggeschoss, hergestellt nach diesem VerfahrenMethod of making a cartridge and cartridge having a sabot projectile made by this method
Die Erfindung betrifft ein Verfahren zur Herstellung einer Patrone mit einem Geschoss und einer verbrennbaren Treibladungshülse sowie einem die Treibladungshülse mit dem Geschoss verbindenden Hülsendeckel, wobei das Geschoss einen dem Hülsendeckel benachbarten Dichtungsring aufweist. Die Erfindung bezieht sich ferner auf eine Patrone mit einem Treibkäfiggeschoss, hergestellt nach diesem Verfahren.The invention relates to a method for producing a cartridge with a projectile and a combustible propellant charge sleeve and a sleeve cover which connects the propellant charge sleeve to the projectile, wherein the projectile has a sealing ring adjacent to the sleeve cover. The invention further relates to a cartridge with a sabot projectile made by this method.
Insbesondere bei großkalibriger Panzermunition mit verbrennbarer Treibladungshülse erfolgt die Anbindung der Treibladungshülse an das Geschoss üblicherweise mittels eines Hülsendeckels, der aus einem verbrennbaren Material (beispielsweise nitrierter kunststoffgetränkter Pappe) oder einem inerten Material (beispielsweise nicht nitrierter kunststoffgetränkter Pappe) bestehen kann. Außerdem erfordert Panzermunition ein verformbares Dichtungsband, damit an dem Geschoss bei seinem Durchgang durch das entsprechende Waffenrohr keine Treibladungsgase vorbeiströmen.Especially with large caliber tank ammunition with combustible propellant charge sleeve, the binding of the propellant charge sleeve to the projectile is usually carried out by means of a sleeve cover, which may consist of a combustible material (for example nitrated plastic-impregnated cardboard) or an inert material (for example non-nitrated plastic-impregnated cardboard). In addition, tank ammunition requires a ductile sealing tape to prevent any propellant gases from passing the missile as it passes through the corresponding gun barrel.
Nachteilig ist bei den bekannten Verfahren unter anderem, dass die Montage der Patronen relativ zeit- und kostenaufwendig ist, da für die Montage des Hülsendeckels und die Montage des Dichtungsringes separate Fertigungslinien erforderlich sind. So wird der Hülsendeckel beispielsweise über eine Verschraubung oder eine Klebeverbindung mit dem heckseitigen Bereich des Geschosskörpers verbunden, während der aus Metall oder Kunststoff bestehende separate Dichtring entweder in eine hierfür vorgesehene Ringnut des Geschosses eingepresst oder eingespritzt wird und anschließend nachbehandelt werden muss.A disadvantage of the known methods, inter alia, that the assembly of cartridges is relatively time consuming and expensive, since separate production lines are required for the assembly of the sleeve cover and the assembly of the sealing ring. Thus, the sleeve cover is connected, for example via a screw or an adhesive connection with the rear-side portion of the projectile body, while the metal or plastic existing separate sealing ring is either pressed or injected into a designated annular groove of the projectile and then has to be post-treated.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs erwähnten Art anzugeben, welches gegenüber vergleichbaren bekannten Verfahren zur Herstellung von Patronen mit Hülsendeckel eine kostengünstigere Montage ermöglicht. Außerdem soll eine Patrone mit einem Treibkäfiggeschoss offenbart werden, die nach diesem Verfahren hergestellt wird.The invention has for its object to provide a method of the type mentioned, which compared to comparable known methods for the preparation of Cartridges with sleeve cover allows a more cost-effective installation. In addition, a cartridge with a sabot projectile to be disclosed, which is produced by this method.
Diese Aufgabe wird erfindungsgemäß hinsichtlich des Verfahrens durch die Merkmale des Anspruchs 1 und hinsichtlich der Patrone durch die Merkmale des Anspruchs 5 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved with respect to the method by the features of claim 1 and with respect to the cartridge by the features of claim 5. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Die Erfindung beruht im Wesentlichen auf dem Gedanken, den Hülsendeckel als Spritzgussteil aus einem elastischen Kunststoff herzustellen, wobei der dem Geschoss zugewandte vorderseitige Bereich des Hülsendeckels den Dichtungsring des Geschosses bildet.The invention is based essentially on the idea to produce the sleeve cover as an injection molded part made of an elastic plastic, wherein the projectile facing the front side portion of the sleeve cover forms the sealing ring of the projectile.
Durch die Integration des Dichtungsringes in den Hülsendeckel wird nicht nur eine einfache Montage der Patrone ermöglicht, sondern durch das Ersetzen des bei bekannten Patronen benutzten, relativ spröden und abriebempfindlichen Materials für den Hülsendeckel durch einen elastischen Kunststoff ist auch die gesamte aus Hülsendeckel, Geschoss und Treibladungshülse bestehende Anordnung bei Umweltbelastungen weniger bruch- und rissanfällig als entsprechende bekannte Anordnungen, da der elastische Kunststoff Verformungsenergie aufnimmt. Außerdem erfolgt bei einem aus Kunststoff bestehenden Hülsendeckel keine unbeabsichtigte Entzündung des Hülsendeckels, wenn dieser beim Laden und Entladen an Teilen der entsprechenden Waffe gerieben wird. Ferner kann eine bei bekannten Hülsendeckeln benötigte Schutzlackierung in der Regel entfallen.The integration of the sealing ring in the sleeve cover not only a simple assembly of the cartridge is possible, but by replacing the used in known cartridges, relatively brittle and abrasion-sensitive material for the sleeve cover by an elastic plastic is also the whole of sleeve cover, projectile and propellant charge existing arrangement with environmental pollution less prone to breakage and cracking than corresponding known arrangements, since the elastic plastic absorbs deformation energy. In addition, there is no inadvertent ignition of the sleeve cover when a sleeve cover made of plastic, if this is rubbed during loading and unloading of parts of the corresponding weapon. Furthermore, a required in known sleeve covers protective coating can be omitted as a rule.
Vorzugsweise sollte der Hülsendeckel zwischen dem als Dichtungsring dienenden Bereich und dem sich daran heckseitig anschließenden Bereich mit einer ringförmigen Sollbruchstelle versehen werden, damit bei Schussabgabe der Hülsendeckel beim Einfädeln des Geschosses in den Kaliberbereich eines entsprechenden Waffenrohres entlang der Sollbruchstellen getrennt wird. Die im Ladungsraumbereich des Waffenrohres dabei verbleibenden Reste des Hülsendeckels werden anschließend durch die Treibladungsgase mündungsseitig aus dem Rohr herausgestoßen.The sleeve cover should preferably be provided with an annular predetermined breaking point between the region serving as a sealing ring and the region adjoining it at the rear, so that upon firing the sleeve cover during threading of the projectile into the caliber region of a corresponding weapon barrel is separated along the predetermined breaking points. The remains of the sleeve cover remaining in the charge space region of the weapon barrel are then expelled from the tube by the propellant charge gases on the outlet side.
Der als Dichtungsring dienende Bereich des Hülsendeckels kann auf das Geschoss auf- gepresst oder aufgeschrumpft oder mittels einer Klebeverbindung an dem Geschoss befestigt werden.The area of the sleeve cover serving as a sealing ring can be pressed or shrunk onto the projectile or attached to the projectile by means of an adhesive bond.
Es kann auch vorgesehen werden, dass der als Dichtungsring dienende Bereich des Hülsendeckels an dem Geschoss durch eine Kontermutter befestigt wird.It can also be provided that the serving as a sealing ring portion of the sleeve cover is fixed to the projectile by a lock nut.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden, anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:
Fig. 1 den Längsschnitt durch den geschossseitigen Teil einer erfindungsgemäßen Patrone mit einem Treibkäfiggeschoss und einem Hülsendeckel;1 shows a longitudinal section through the projectile-side part of a cartridge according to the invention with a sabot projectile and a sleeve cover;
Fig. 2 eine vergrößerte Ansicht des in Fig. 1 dargestellten Hülsendeckels undFig. 2 is an enlarged view of the sleeve cover shown in Fig. 1 and
Fig. 3 eine perspektivische Ansicht des in Fig. 2 dargestellten Hülsendeckels.Fig. 3 is a perspective view of the sleeve cover shown in Fig. 2.
In Fig. 1 ist mit 1 eine aus einer großkalibrigen Glattrohrkanone verschießbare Patrone bezeichnet, die ein Treibkäfiggeschoss 2, eine nur gestrichelt angedeutete Treibladungshülse 3 und einen die Treibladungshülse 3 und das Treibkäfiggeschoss 2 verbindenden Hülsendeckel 4 umfasst. Dabei setzt sich das Treibkäfiggeschoss 2 im Wesentlichen aus einem unterkalibrigen Penetrator 5 und einem abwerfbaren Treibkäfig 6 zusammen. Bei dem Treibkäfig 6 handelt es sich bei diesem Ausführungsbeispiel um einen Stoßtreibkäfig mit einem heckseitig auf den unterkalibrigen Penetrator 5 wirkenden plattenförmigen Treibelement 7. Erfindungsgemäß handelt es sich bei dem Hülsendeckel 4 um ein Spritzgussteil aus einem elastischen Kunststoff, dessen vorderseitiger Bereich 8 (Fig. 2) das Treibelement 7 des Treibkäfigs 6 außenseitig umschließt und den Dichtungsring des Treibkäfiggeschosses 2 bildet.In Fig. 1 is denoted by 1 a shootable from a large-caliber smooth tube gun cartridge comprising a sabot projectile 2, a dashed line indicated only propellant 3 and the propellant shell 3 and the sabot floor 2 connecting sleeve cover 4. In this case, the sabot projectile 2 essentially consists of a subcaliber penetrator 5 and a disposable sabot 6. The sabot 6 in this exemplary embodiment is a shock-absorbing cage with a plate-shaped driving element 7 acting on the rear side of the subcaliber penetrator 5. According to the invention, the sleeve cover 4 is an injection molded part made of an elastic plastic whose front region 8 (FIG. 2) surrounds the drive element 7 of the sabot 6 on the outside and forms the sealing ring of the sabot projectile 2.
Um bei Schussabgabe ein definiertes Ablösen des Treibkäfiggeschosses 2 von der Treibladungshülse 3 sicherzustellen, ist zwischen dem Dichtungsring 8 und dem sich daran anschließenden heckseitigen Bereich 9 eine ringförmige Sollbruchstelle 10 vorgesehen. Diese wird vorteilhafterweise derart angeordnet, dass sie sich bei in einer Rohrwaffe geladenen Patrone 1 im Bereich des Konusüberganges zum Ladungsraum der entsprechenden Waffe befindet, so dass bei Schussabgabe der Hülsendeckel 4 beim Einfädeln des Treibkäfiggeschosses 2 in den Kaliberbereich des entsprechenden Waffenrohres entlang der Sollbruchstellen 10 getrennt wird. Die im Ladungsraumbereich des Waffenrohres dabei verbleibenden Reste des Hülsendeckels 4 werden anschließend durch die Treibladungsgase mündungsseitig aus dem Rohr herausgestoßen.In order to ensure a defined detachment of the sabot projectile 2 from the propellant charge case 3 upon firing, an annular predetermined breaking point 10 is provided between the sealing ring 8 and the adjoining rear region 9. This is advantageously arranged so that it is in loaded in a gun barrel cartridge 1 in the region of the cone transition to the cargo space of the corresponding weapon, so that when firing the sleeve cover 4 when threading the sabot projectile 2 in the caliber area of the corresponding gun barrel along the predetermined breaking points 10 separated becomes. The remains of the sleeve cover 4 remaining in the charge space region of the weapon barrel are subsequently expelled from the tube by the propellant charge gases on the outlet side.
Wie Fig. 1 entnehmbar, ist bei dem dargestellten Ausführungsbeispiel der Hülsendeckel 4 an dem Treibkäfiggeschoss 2 durch eine auf das plattenförmige Treibelement 7 heckseitig aufgeschraubte Kontermutter 11 befestigt.As shown in FIG. 1, in the illustrated embodiment, the sleeve cover 4 is attached to the sabot floor 2 by a rear nut screwed onto the plate-shaped driving element 7 lock nut 11.
Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So muss es sich bei der Patrone nicht zwingend um eine solche mit leitwerkstabilisiertem Treibkäfiggeschoss handeln. Vielmehr kann das erfindungsgemäße Verfahren beispielsweise auch bei Patronen mit leitwerkstabilisiertem kalibergleichen Geschosskörper verwendet werden. In diesem Fall kann die Befestigung des als Dichtungsring dienenden Bereiches des Hülsendeckels an dem üblicherweise kegelförmig ausgebildeten Bereich des dem Geschosskörper zugewandten Leitwerkträgers erfolgen. BezugszeichenlisteOf course, the invention is not limited to the embodiment described above. Thus, the cartridge does not necessarily have to be one with a stator-stabilized sabot projectile. Rather, the method according to the invention can also be used, for example, in cartridges with guide-stabilized bullet-shaped bodies. In this case, the attachment of serving as a sealing ring portion of the sleeve cover can be done on the usually conically shaped portion of the projectile body facing Leitwerkträgers.
