Description

Die Erfindung betrifft eine Treibladungshülse nach dem Oberbegriff des Anspruchs 1.The invention relates to a propellant charge case according to the preamble of claim 1.

Aus der DE-AS 14 46 889 ist es bekannt, Treibladungshülsen auf der Basis von Nitrozellulose herzustellen, wobei auf einem Ansaugwerkzeug ein Vlies erzeugt wird, das nach seiner Trocknung zusätzlich imprägniert wird.From DE-AS 14 46 889 it is known to produce propellant charge sleeves based on nitrocellulose, a fleece being produced on a suction tool which is additionally impregnated after it has dried.

Ferner ist es aus der DE-PS 14 53 842 bekannt, für eine Treibladungshülse eine rohrförmige Hülle aus einem Vlies auf Nitrozellulose-Basis zu verwenden, die zwischen einem äußeren und einem inneren bodenseitig angeordneten Verbindungsbecher eingeklemmt wird, wobei der innere Verbindungsbecher Löcher aufweist, die eine rückstandsfreie Verbrennung des Vlieses sicherstellen. Der äußere Verbindungsbecher wird in einen Boden eingesetzt. Dies erfordert jedoch einen relativ aufwendigen Aufbau der Treibladungshülse im Bodenbereich.Furthermore, it is known from DE-PS 14 53 842 to use a tubular shell made of a fleece based on nitrocellulose for a propellant charge sleeve, which is clamped between an outer and an inner connection cup arranged on the bottom, the inner connection cup having holes which ensure residue-free combustion of the fleece. The outer connection cup is inserted into a floor. However, this requires a relatively complex structure of the propellant charge sleeve in the bottom area.

Zusätzlich ist es an sich etwa aus der DE-PS 34 18 61 bekannt, den Boden von Treibladungshülsen mittels eines Versteifungsrings zu verstärken, während gemäß der DE-OS 15 78 153 bei einer Treibladungshülse für Jagdpatronen ein Metalleinsatz zur Verstärkung des Hülsenbodens und der Öffnung für die Zündkapsel in axialer und radialer Richtung vorgesehen ist.In addition, it is known per se from DE-PS 34 18 61 to reinforce the bottom of propellant charge cases by means of a stiffening ring, while according to DE-OS 15 78 153 a metal insert for reinforcing the case base and the opening for a propellant charge case for hunting cartridges the primer is provided in the axial and radial directions.

Treibladungshülsen mit einer Hülle aus einem Vlies auf Nitrozellulose-Basis besitzen den Vorteil eines kleinen spezifischen Gewichts und der rückstandsfreien Verbrennung in Waffenrohren unter Druck und Temperatur. Ferner fällt in den Kampfräumen kein "Leergut" an, und außerdem ist die CO-Konzentration im Vergleich zu Metallhülsen sehr gering. Nachteilig ist jedoch, daß die Eigenfestigkeit dieses Materials nicht weiter gesteigert werden kann, ohne die genannten Vorteil nachteilig zu verändern. Dies beeinträchtigt die Verwendung insbesondere bei Munition größerer Kaliber, etwa Panzermunition, die erheblichen mechanischen Beanspruchungen durch Laden und Entladen, Schock und Vibration ausgesetzt ist, da hierbei das Vlies an Schwachstellen beschädigt oder zerstört werden kann. Die Folgen sind Schwieri gkeiten beim Laden oder Entladen oder auch herausrieselndes Treibladungspulver. Dies alles stellt eine Gefahr für den Soldaten dar.Propellant charge cases with a cover made of a fleece based on nitrocellulose have the advantage of a small specific weight and the residue-free combustion in weapon tubes under pressure and temperature. Furthermore, there is no "empties" in the fighting rooms, and the CO concentration is very low compared to metal sleeves. However, it is disadvantageous that the inherent strength of this material cannot be increased further without disadvantageously changing the mentioned advantage. This affects the use in particular of ammunition of larger caliber, such as tank ammunition, which is exposed to considerable mechanical stresses from loading and unloading, shock and vibration, since the fleece can be damaged or destroyed at weak points. The consequences are difficulties when loading or unloading or propellant powder that trickles out. All of this poses a threat to the soldier.

Aufgabe der Erfindung ist es, eine Treibladungshülse nach dem Oberbegriff des Anspruchs 1 zu schaffen, bei der die zu erwartenden mechanischen Beanspruchungen keine Beschädigungen hervorrufen, jedoch die rückstandsfreie Verbrennung des Vlieses erhalten bleibt.The object of the invention is to provide a propellant charge sleeve according to the preamble of claim 1, in which the mechanical loads to be expected do not cause any damage, but the residue-free combustion of the nonwoven is retained.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved in accordance with the characterizing part of claim 1.

Gleichzeitig wird hierdurch sichergestellt, daß die Versteifungen für die Schwachstellen der Treibladungshülse, die mit dem Vlies verbunden sind, nicht im Waffenrohr liegenbleiben. Die Versteifungen können bei der Herstellung entsprechend in das Werkzeug eingelagert werden.At the same time, this ensures that the stiffeners for the weak points of the propellant charge sleeve, which are connected to the fleece, do not remain in the gun barrel. The stiffeners can be appropriately stored in the tool during manufacture.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further embodiments of the invention can be found in the following description and the subclaims.

Die Erfindung wird nachstehend anhand der in den beigefügten Abbildungen dargestellten Ausführungsbeispiele näher erläutert.

  • Fig. 1 zeigt ausschnittweise ein Geschoß mit Treibladungshülse im Schnitt.
  • Fig. 2 zeigt vergrößert den Bodenbereich der Treibladungshülse von Fig. 1.
  • Fig. 3 bis 9 zeigen weitere Ausführungsformen von Treibladungshülsen entsprechend der Darstellung von Fig. 2.
The invention is explained in more detail below on the basis of the exemplary embodiments illustrated in the attached figures.
  • Fig. 1 shows a section of a projectile with propellant charge sleeve in section.
  • FIG. 2 shows an enlarged view of the bottom region of the propellant charge sleeve from FIG. 1.
  • 3 to 9 show further embodiments of propellant charge sleeves corresponding to the illustration in FIG. 2.

In Fig. 1 ist ein Geschoß 1 mit Treibkäfig 2 dargestellt, das über eine Dichtung 3 mit einer Treibladungshülse 4 verbunden ist. Die Treibladungshülse 4 besitzt einen metallischen wiederverwendbaren Boden 5 mit einer Bohrung 6 zur Aufnahme einer Zündkapsel 7. Die Treibladungshülse 4 besitzt ferner eine Hülle 8 aus einem Vlies auf Nitrozellulose-Basis. Die Hülle 8 besitzt benachbart zur Dichtung 3 einen gekrümmten Abschnitt 9, der bis zu einer Bohrung 10 verlängert ist, durch die sich das Geschoß 1 erstreckt. Der Bereich 9 kann auch im Schnitt winkelförmig ausgebildet sein, etwa bei Aufnahme eines Geschosses 1 ohne Treibkäfig durch die Treibladungshülse 4. Ferner besitzt die Hülle 8 im Bodenbereich einen gekrümmten Abschnitt 11 in Anpassung an die Krümmung des Bodens 5, der sich bodenseitig bis zum Mittelzapfen 12 des Bodens, der die Bohrung 6 enthält, erstreckt.In Fig. 1 a floor 1 with sabot 2 is shown, which is connected via a seal 3 to a propellant charge sleeve 4. The propellant charge sleeve 4 has a metallic, reusable base 5 with a bore 6 for receiving a primer 7. The propellant charge sleeve 4 also has a sleeve 8 made of a fleece based on nitrocellulose. The casing 8 has, next to the seal 3, a curved section 9 which is extended to a bore 10 through which the projectile 1 extends. The area 9 can also have an angular section, for example when a projectile 1 is received without a sabot through Propellant charge sleeve 4. Furthermore, the sleeve 8 has a curved section 11 in the base region in adaptation to the curvature of the base 5, which extends on the base side to the central pin 12 of the base, which contains the bore 6.

Schwachstellen der Hülle 8, die durch mechanische Beanspruchungen gefährdet sind, sind die Abschnitte 9, 11 sowie die Abschnitte um die Bohrung 10 bzw. den Mittelzapfen 12. Dementsprechend sind in diesen Bereichen Versteifungen 13 aus Metall oder Kunststoff vorgesehen.Sections 9, 11 and the sections around the bore 10 and the central pin 12 are weak points of the casing 8 which are endangered by mechanical stresses. Accordingly, stiffeners 13 made of metal or plastic are provided in these areas.

Bei der in Fig. 2 dargestellten Ausführungsform besteht die Versteifung 13 aus einer gelochten Einlage aus Metallblech oder Kunststoff. Da der Boden 5 die Hülle 8 im Bereich 11 schützt, kann die Versteifung 13 gegebenenfalls auch nur um die den Mittelzapfen 12 umgebende Bohrung 14 herum vorgesehen sein, wie in Fig. 3 dargestellt ist. Gegebenenfalls reicht auch eine Versteifung 13 in Form eines Verstärkungsrings an dieser Stelle, wie sie in Fig. 9 dargestellt ist. Die Versteifung 13 der Ausführungsformen der Figuren 2 und 3 besitzt einen die Bohrung 14 begrenzenden Innenring 15.In the embodiment shown in Fig. 2, the stiffener 13 consists of a perforated insert made of sheet metal or plastic. Since the base 5 protects the casing 8 in the area 11, the stiffening 13 can optionally also be provided only around the bore 14 surrounding the central pin 12, as shown in FIG. 3. If necessary, a stiffening 13 in the form of a reinforcing ring at this point, as shown in FIG. 9, is sufficient. The stiffening 13 of the embodiments of FIGS. 2 and 3 has an inner ring 15 delimiting the bore 14.

Bei der in Fig. 4 dargestellten Ausführungsform ist die Versteifung 13 nicht wie bei Fig. 2 und 3 als Einlage, sondern als Auflage ausgebildet, die von der Außenseite auf die Hülle 8 durch Kleben oder, wie in der linken Hälfte von Fig. 4 dargestellt ist, durch Einrollen befestigt ist. Auch hierbei kann die Versteifung 13 in das Ansaugwerkzeug zum Herstellen der Hülle 8 eingelegt werden. Da bei der Ausführungsform von Fig. 4 die Versteifung 13 sich nur außenseitig zur Hülle 8 befindet, benötigt man hier keine Durchbrüche in der Versteifung 13, da die rückstandsfreie Verbrennung der Hülle 8 gewährleistet ist.In the embodiment shown in FIG. 4, the stiffening 13 is not designed as an insert, as in FIGS. 2 and 3, but rather as a support, which is glued onto the casing 8 from the outside or, as shown in the left half of FIG. 4 is attached by curling. Here, too, the stiffening 13 can be inserted into the suction tool for producing the casing 8. Since in the embodiment of FIG. 4 the stiffening 13 is only on the outside of the casing 8, no openings in the stiffening 13 are required here, since the residue-free combustion of the casing 8 is ensured.

Bei der in Fig. 5 dargestellten Ausführungsform ist die im Schnitt L-förmige Versteifung 13 in die Wandung der Hülle 8 eingearbeitet, so daß die Hülle 8 überall im wesentlichen gleiche Wandstärke aufweist. Die hierfür notwendige Ausnehmung ist durch mechanische Bearbeitung hergestellt. Da infolg e dieser mechanischen Bearbeitung derjenige Bereich der Hülle 8, der den größten Festigkeits- und Dichtebereich aufweist, entfernt wird, während der filzige Mittelbereich der Hülle 8 verbleibt, ist eine Nachimprägnierung des verbliebenen Teils der Hülle 8 zur Verfe stigung derselben zweckmäßig.In the embodiment shown in Fig. 5, the cross-sectionally L-shaped stiffening 13 is incorporated into the wall of the casing 8, so that the casing 8 has essentially the same wall thickness everywhere. The recess required for this is made by mechanical processing. Since, as a result of this mechanical processing, that area of the casing 8 which has the greatest strength and density area is removed, while the felted central area of the casing 8 remains, re-impregnation of the remaining part of the casing 8 is available Appropriate the same.

Bei der in Fig. 6 dargestellten Ausführungsform ist die Versteifung 13 im Bereich der Bohrung 14 um die Hülle 8 herum geklemmt, wobei zumindest an der Innenseite die Versteifung 13 Löcher 16 aufweist, um eine rückstandsfreie Verbrennung der Hülle 8 zu gewährleisten. Hierbei ist die Versteifung 13 wie bei der Ausführungsform von Fig. 5 bündig mit den Außenseiten der Hülle 8 angeordnet und die Hülle 8 in diesem Bereich zweckmäßigerweise nachimprägniert.In the embodiment shown in FIG. 6, the stiffening 13 is clamped around the casing 8 in the region of the bore 14, the stiffening 13 having holes 16 at least on the inside in order to ensure residue-free combustion of the casing 8. Here, as in the embodiment of FIG. 5, the stiffening 13 is arranged flush with the outer sides of the casing 8 and the casing 8 is expediently impregnated in this area.

Wie Fig. 7 zeigt, können zur Befestigung der im Schnitt U-förmigen Versteifung 13 auch Niet- oder Schraubverbindungen 17 verwendet werden.As shown in FIG. 7, rivet or screw connections 17 can also be used to fasten the U-shaped stiffener 13 in section.

Die Versteifung 13 kann auch aus Gewebe aus Metall oder Kunststoff bestehen, wie in Fig. 8 angedeutet ist. The stiffening 13 can also consist of fabric made of metal or plastic, as indicated in FIG. 8.
