Description

Die Erfindung betrifft eine Patrone mit einer mit Treibladungspulver mindestens teilweise gefüllten Treibladungshülse und einem sich vorderseitig an die Treibladungshülse anschließenden Geschossteil.The invention relates to a cartridge with a propellant charge powder at least partially filled propellant charge tube and a front side of the propellant charge shell subsequent bullet.

Bei derartigen Patronen besteht die Treibladungshülse üblicherweise aus einem Hülsendeckel, einem Hülsenmantel und einem Hülsenboden aus Metall, wobei der aus einem verbrennbaren Material bestehende Hülsenmantel einerseits über den Hülsendeckel mit dem Geschossteil und andererseits über ein Federblech und einen Sicherungsring mit dem Hülsenboden verbunden ist.In such cartridges, the propellant charge sleeve usually consists of a sleeve cover, a sleeve casing and a sleeve bottom made of metal, wherein the existing of a combustible material sleeve casing is connected on the one hand via the sleeve cover with the projectile part and on the other hand via a spring plate and a locking ring with the sleeve bottom.

Treibladungshülsen der vorgenannten Art können sowohl bei Gefechtspatronen als auch bei Übungspatronen verwendet werden.Propellant cases of the aforementioned type can be used both in combat cartridges and training cartridges.

Insbesondere zur Herstellung einer kostengünstigen KE -Übungsmunition ist neben der Erzeugung eines möglichst kostengünstigen Geschosses auch ein geringeres Geschossgewicht mitentscheidend. Mit einem geringeren Geschossgewicht kann auch die Antriebsleistung bzw. die Menge des Treibladungspulvers stark reduziert werden. Eine stark reduzierte Menge im Antriebsvolumen bedeutet aber bei gleich bleibendem Laboriervolumen eine ungleiche Verteilung des Schüttpulvers in der Patrone nach dem Laden. Damit verbunden entstehen während der Anzündung unerwünschte Druckwellen.In particular, for the production of a cost KE exercise ammunition in addition to the generation of a cost-effective projectile as well as a lower bullet weight is crucial. With a lower bullet weight and the drive power or the amount of propellant charge powder can be greatly reduced. However, a greatly reduced amount in the drive volume means an unequal distribution of bulk powder in the cartridge after loading, while maintaining the same laboratory volume. Associated with this, unwanted pressure waves occur during ignition.

Der Erfindung liegt die Aufgabe zugrunde, den oben genannten Nachteil zu vermeiden.The invention has for its object to avoid the above drawback.

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, eine Zentrierung des Treibladungspulvers im Laborierraum sowohl radial als auch in Achsrichtung der Patrone vorzusehen. Dabei soll aber weniger auf Füllstücke oder Laborierscheiben als Laborierhilfe zurückgegriffen werden, sondern vielmehr auf eine Art Pulversack bzw. Beutel, welcher die Treibladung aufnimmt und zentriert. Füllstücke haben den Nachteil, dass sie, wenn sie aus Styropor bestehen, Salzsäure bei der Verbrennung im Rohr entwickeln oder, wenn sie aus Watte bestehen, nach Beschuss im Leitwerk hängen bleiben können. Die Nutzung von Laborierscheiben bringt den Nachteil mit sich, dass die Scheiben mittels Kleber befestigt werden müssen.The invention is based essentially on the idea of centering the propellant charge powder provide in the laboratory space both radially and in the axial direction of the cartridge. But it should be used less as a laboratory aid on filling pieces or Laborierscheiben, but rather on a kind of powder bag or bag, which receives the propellant charge and centered. Patches have the disadvantage that, if they are made of styrofoam, they develop hydrochloric acid in the combustion in the pipe or, if they are made of cotton, can get stuck after firing in the tail. The use of Laborierscheiben has the disadvantage that the discs must be fixed by means of adhesive.

Beutelladungen zur Aufnahme von Treibladungen als solche sind insbesondere bei modularen Treibladungen bekannt. Jedoch ist deren Aufgabe und Aufbau etc. anders gelagert, als hier vorgeschlagen. Die Treibbeutelladungen werden einem Waffensystem getrennt von einem Geschoss zugeführt, wie u. a. der DE 198 21 050 A1 entnehmbar. Die Anordnung dieser Beutelladungen in einem Waffenrohr zeigt die DE 198 52 360 C2 . Ein Verfahren und eine Vorrichtung zur Handhabung von kombinierbaren Treibladungen werden in der DE 697 21 037 T2 offenbart.Bagloads for holding propellant charges as such are known in particular in modular propellant charges. However, their task and structure, etc. stored differently than suggested here. The Treibbeutelladungen be supplied to a weapon system separated from a projectile, such as the DE 198 21 050 A1 removable. The arrangement of these bag loads in a gun barrel shows the DE 198 52 360 C2 , A method and apparatus for handling combinable propellant charges are disclosed in U.S. Patent No. 5,376,854 DE 697 21 037 T2 disclosed.

Die US 5 090323 , welche als Ausgangspunkt für der Oberbegriff des Anspruches 1 dient, betrifft einen Einkapselungssack für eine Treibladung. Dieser ist zweiteilig ausgebi!det und weit vorne, unterhalb eines Dichtungsbandes am Geschoss befestigt.The US 5 090323 , which serves as a starting point for the preamble of claim 1, relates to an encapsulating bag for a propellant charge. This is designed in two parts and attached far ahead, below a sealing strip on the projectile.

Aus der DE 72 34 535 U1 ist eine mit einer als Faltbeutel ausgebildeten Treibladungshülse bekannt. Dieser formt die Form der Hülse nach und ist über der eingefüllten Treibladung zusammengefaltet und verschweißt sowie in den Hülsenmund eingeschoben.From the DE 72 34 535 U1 is one with a designed as a folding bag propellant charge sleeve known. This shapes the shape of the sleeve and is folded over the filled propellant charge and welded and inserted into the sleeve mouth.

In der hier vorgeschlagenen Treibladungshülse wird erfindungsgemäß ein jeweils mit der entsprechenden Menge an Treibladungspulver vollständig gefüllter sackförmiger (gestreckter) Behälter (Pulversack) derart angeordnet, dass der Behälter -und damit auch das Treibladungspulver- sich in Richtung der zentralen Längsachse der Patrone erstreckt, wobei die Längsachse gleichzeitig die Symmetrieachse des sackförmigen Behälters ist.In the propellant charge sleeve proposed here, according to the invention, a bag-shaped (elongated) container (powder bag) which is completely filled with the appropriate amount of propellant powder is arranged in such a way that the container, and thus also the propellant charge powder, extends in the direction of the central longitudinal axis of the cartridge Longitudinal axis is the symmetry axis of the bag-shaped container at the same time.

Dabei wird der bodenseitige Endbereich des sackförmigen Behälters ebenfalls mittels eines Federbleches am Hülsenboden der Treibladungshülse und der geschossseitige Endbereich des sackförmigen Behälters an einer vorzugsweise aus spritzfähigem Kunststoff bestehenden Laborierhilfe befestigt, die sich senkrecht zur Längsachse der Patrone erstreckt und mit ihrem äußeren Umfang kraft- und/oder formschlüssig mit dem Hülsenmantel und/oder dem Hülsendeckel der Treibladungshülse verbunden ist. Der Beutel ist dadurch gestreckt und bildet eine Art innere Hülse.In this case, the bottom-side end portion of the bag-shaped container is also secured by means of a spring plate on the sleeve bottom of the propellant charge shell and the projectile end of the bag-shaped container on a preferably made of injection-molded plastic Laborierhilfe extending perpendicular to the longitudinal axis of the cartridge and / or force with its outer circumference and / or is positively connected to the sleeve casing and / or the sleeve cover of the propellant charge sleeve. The bag is thereby stretched and forms a kind of inner sleeve.

Bei einer vorteilhaften Ausführungsform der Erfindung ist die Laborierhilfe hutförmig ausgebildet und weist eine sich in Richtung des Geschossteiles erstreckende halbkugelförmige Ausbuchtung auf, die sich axial an den sackförmigen Behälter anschließt und einen die Ausbuchtung umgebenden, flach ausgebildeten Randbereich aufweist, der stirnseitig mit dem Hülsenmantel und/oder dem Hülsendeckel kraft- und/oder formschlüssig verbunden ist.In an advantageous embodiment of the invention, the laboratory aid is hat-shaped and has a hemispherical bulge extending in the direction of the projectile part, which adjoins the bag-shaped container axially and has a flat edge region surrounding the bulge, which is provided with the sleeve shell and / or or the sleeve cover is non-positively and / or positively connected.

Zur Befestigung des sackförmigen Behälters an der Laborierhilfe sind vorteilhafter Weise in dem Übergangsbereich zwischen der halbkugelförmigen Ausbuchtung und dem flachen Randbereich mindestens zwei gegenüberliegende schlitzförmige Ausnehmungen vorgesehen, durch welche zwei vordere, axial voneinander getrennte fahnenförmige Bereiche des sackförmigen Behälters hindurchgeführt und vorderseitig mit der kugelförmigen Ausbuchtung verbunden sind.For attachment of the bag-shaped container to the Laborierhilfe advantageously at least two opposing slot-shaped recesses are provided in the transition region between the hemispherical bulge and the flat edge region, passed through which two front, axially separate flag-shaped areas of the bag-shaped container and front side connected to the spherical bulge are.

Dabei können die beiden fahnenförmigen Endbereiche des sackförmigen Behälters miteinander verknotet oder mit der halbkugelförmigen Ausbuchtung verklebt sein.In this case, the two flag-shaped end portions of the bag-shaped container can be knotted together or glued to the hemispherical bulge.

Als besonders vorteilhaft hat es sich erwiesen, wenn die stirnseitige Befestigung der Laborierhilfe im Übergangsbereich zwischen Hülsenmantel und Hülsendeckel erfolgt, da die Laborierscheibe dann auch die Haltbarkeit der Verbindung von Hülsenmantel und Hülsendeckel unterstützt.To be particularly advantageous, it has been found that the frontal attachment of the laboratory aid in the transition region between the sleeve casing and sleeve cover takes place, since the Laborierscheibe then also supports the durability of the connection of sleeve casing and sleeve cover.

Die Laborierhilfe selbst ist in der Trieibladungshülse integrierbar und schnappt in den Hülsendeckel ein. Sie dient als Formschluss zwischen der Hülse und dem Hülsendeckel. Festgehalten werden beide durch einen Stopfen oder dergleichen. Der Beutel ist von oben als auch von unten befüllbar. Der Hülsendeckel, vorzugsweise aus Kunststoff bestehend, besitzt wenigstens ein Führungsband mit Sollbruchstellen sowie Hinterschneidungen, hinter welche die Laborierhilfe einschnappen kann.The Laborierhilfe itself can be integrated in the Trieibladungshülse and snaps into the sleeve cover. It serves as a positive connection between the sleeve and the sleeve cover. Both are held by a plug or the like. The bag can be filled from above as well as from below. The sleeve cover, preferably made of plastic, has at least one guide band with predetermined breaking points and undercuts behind which the laboratory aid can snap.

Alternativ kann eine Zentrierung nach der Aufgabe der Erfindung durch eine weitere Hülse (zweiter Hülsenmantel) mit einem schmaleren Durchmesser als die Geschosshülse geschaffen werden. Die zweite schmalere Hülse ist dabei für die Treibladung bestimmt. Durch den konstanten Durchmesser wird die Innenballistik verbessert.Alternatively, a centering according to the object of the invention by a further sleeve (second sleeve jacket) can be created with a smaller diameter than the bullet sleeve. The second narrower sleeve is intended for the propellant charge. The constant diameter improves the internal ballistics.

In Fig.1 ist mit 1 eine erfindungsgemäße Übungspatrone bezeichnet, die eine Treibladungshülse 2 und ein vorderseitig an der Treibladungshülse 2 befestigtes Käfiggeschoß 3 umfasst. Letzteres besteht im Wesentlichen aus einem unterkalibrigen Penetrator 4 mit Kegelleitwerk (nicht dargestellt) und einem Käfig 6 (Führungskäfig).In Fig.1 1 denotes a practice cartridge according to the invention which comprises a propellant charge sleeve 2 and a cage projectile 3 fastened to the front of the propellant charge sleeve 2. The latter essentially consists of a subcaliber penetrator 4 with a conical structure (not shown) and a cage 6 (guide cage).

Die Treibladungshülse 2 setzt sich aus einem Hülsendeckel 7, einem aus verbrennbarem Material bestehenden, relativ dünnen Hülsenmantel 8 und einem beispielsweise aus Stahl bestehenden Hülsenboden 9 zusammen. Der Hülsenmantel 8 ist mittels eines Federbleches 10 und eines Sicherungsringes (nicht dargestellt) in an sich bekannter Weise an einem zentralen Vorsprung 11 des Hülsenbodens 9 befestigt. Mit diesem Vorsprung 11 ist ebenfalls ein an sich bekannter Treibladungsanzünder 12 verbunden, welcher sich axial in den Innenraum der Treibladungshülse 2 erstreckt.The propellant charge tube 2 is composed of a sleeve cover 7, a combustible material consisting of relatively thin sleeve jacket 8 and a steel sleeve base 9 consisting for example of steel. The sleeve jacket 8 is fixed by means of a spring plate 10 and a retaining ring (not shown) in a conventional manner to a central projection 11 of the sleeve bottom 9. This projection 11 is also connected to a known propellant charge igniter 12, which extends axially into the interior of the propellant charge shell 2.

Erfindungsgemäß ist nun vorgesehen, dass das in der Treibladungshülse 2 befindliche Treibladungspulver 13 in einem sackförmigen Behälter 14 aus einem Baumwollgewebe angeordnet ist, welcher sich in Richtung der Längsachse 100 der Übungspatrone 1 erstreckt und dessen bodenseitiger Endbereich 15 ebenfalls mittels des Federbleches 10 am Hülsenboden 9 befestigt ist, so dass er auch den Treibladungsanzünder 12 enthält.According to the invention, it is now provided that the propellant charge powder 13 contained in the propellant charge casing 2 is arranged in a bag-shaped container 14 made of a cotton fabric which extends in the direction of the longitudinal axis 100 of the practice cartridge 1 and whose bottom end region 15 is likewise fastened to the casing bottom 9 by means of the spring plate 10 is so that it also contains the propellant charge 12.

Der geschoßseitige Endbereich 16 des sackförmigen Behälters 14 ist hingegen an einer Laborierscheibe 17 aus Kunststoff befestigt. Diese besitzt mittig eine halbkugelförmige Ausbuchtung 18, die einen Durchmesser aufweist, welcher dem Durchmesser des sackförmigen Behälters 14 entspricht, sowie einen diese Ausbuchtung 18 umfassenden flachen Randbereich 19.The projectile-side end portion 16 of the bag-shaped container 14, however, is attached to a Laborierscheibe 17 made of plastic. This has in the center a hemispherical bulge 18, which has a diameter which corresponds to the diameter of the bag-shaped container 14, and a flat edge region 19 comprising this bulge 18.

Der Randbereich 19 ist stirnseitig in dem Übergangsbereich zwischen Hülsenmantel 8 und Hülsendeckel 7 formschlüssig mit der Treibladungshülse 2 verbunden und bewirkt eine axiale und radiale Zentrierung des sackförmigen Behälters 14 sowie des darin befindlichen Treibladungspulvers 13.The edge region 19 is frontally connected in the transition region between the sleeve jacket 8 and sleeve cover 7 form-fitting manner with the propellant charge sleeve 2 and causes an axial and radial centering of the sack-shaped container 14 and the propellant charge powder 13 therein.

Wie Fig.2 entnehmbar ist, weist der Hülsendeckel 7 heckseitig Hiterschneidungen 20 auf, welche beim Aufschieben des Hülsendeckels 7 auf den Hülsenmantel 8 hinter den Randbereich der Laborierscheibe 17 greifen und diese in dem Raum 21 vor dem Hülsendeckel 7 fixieren.As Fig.2 can be removed, the sleeve cover 7 rear Hiterschneidungen 20 which engage when pushing the sleeve cover 7 on the sleeve jacket 8 behind the edge region of the laboratory 17 and fix them in the space 21 in front of the sleeve cover 7.

Fig.3 zeigt den sackförmigen Behälter 14 vor seiner Befestigung innerhalb der Treibladungshülse 2. Er weist an seinem bodenseitigen Endbereich 15 eine Öffnung 22 auf, mittels welcher der Behälter 14 auf den Vorsprung 11 des Hülsenbodens 9 geschoben und dann mit dem Federblech 10 befestigt wird. Figure 3 It has at its bottom end portion 15 an opening 22 by means of which the container 14 is pushed onto the projection 11 of the sleeve bottom 9 and then secured to the spring plate 10.

Der geschossseitige Endbereich 16 des sackförmigen Behälters 14 ist axial getrennt, so dass sich zwei getrennte fahnenförmige Bereiche 23, 24 ergeben. Diese fahnenförmigen Bereiche 23, 24 werden jeweils durch eine schlitzförmige Ausnehmung 25 der Laborierscheibe 17 hindurchgeführt, welche zwischen der halbkugelförmigen Ausbuchtung 18 und dem flachen Randbereich 19 angeordnet sind und jeweils eine etwa sichelförmige Form aufweisen (Fig.4).The projectile-side end region 16 of the sack-shaped container 14 is separated axially, so that two separate flag-shaped regions 23, 24 result. These flag-shaped regions 23, 24 are each passed through a slot-shaped recess 25 of the laboratory 17, which are arranged between the hemispherical bulge 18 and the flat edge portion 19 and each having an approximately sickle-shaped shape ( Figure 4 ).

Zur Befestigung des sackförmigen Behälters 14 an der Laborierscheibe 17 können die beiden fahnenförmigen Bereiche 23, 24 miteinander verknotet werden (in Fig.1 als spitzer Bereich 26 angedeutet). Es kann aber auch vorgesehen werden, dass die fahnenförmigen Bereiche 23, 24 mit der Laborierscheibe 17 vorderseitig verklebt werden.For attachment of the sack-shaped container 14 to the Laborierscheibe 17, the two flag-shaped portions 23, 24 are knotted together (in Fig.1 indicated as a pointed area 26). But it can also be provided that the flag-shaped regions 23, 24 are glued to the front of the laboratory 17.

Der so in dem sackförmigen Behälter 14 entstehende Raum für das Treibladungspulver 13 ist im Wesentlichen abhängig von dem Durchmesser des verwendeten Federbleches 10, der Größe der schlitzförmigen Ausnehmungen 25 in der Laborierscheibe 17, der festgelegten axialen Position der Laborierscheibe 17 innerhalb der Treibladungshülse 2 sowie der Form der Laborierscheibe 17 und kann daher, entsprechend der zu laborierenden Menge an Treibladungspulver, in weiten Grenzen variiert werden.The resulting space in the bag-shaped container 14 for the propellant charge powder 13 is essentially dependent on the diameter of the spring plate used 10, the size of the slot-shaped recesses 25 in the Laborierscheibe 17, the fixed axial position of the Laborierscheibe 17 within the propellant charge shell 2 and the shape of the Laborierscheibe 17 and therefore, according to the amount of propellant to be labored, can be varied within wide limits.

Fig. 5 zeigt den Hülsendeckel 7 (auch Hülsenkappe) in einer perspektivischen Darstellung. Der Hülsendeckel 7 weist scharfkantige Sollbruchstellen 7.1 sowie einen umlaufenden Hals 7.2 auf, an welchem der Käfig 6 angreift. Fig. 5 shows the sleeve cover 7 (also sleeve cap) in a perspective view.
