Abstract

The invention provides cartridge ammunition (1), in particular of medium caliber, having a projectile (2) and a propellant charge casing (3) which is connected to the projectile (2), wherein a propellant charge (7) is provided in a propellant chamber (6) of the propellant charge casing (3) and has a functional connection to an igniting cap (11) of an ignition device, which is placed in a plug (14) that can be introduced into a hole (12) in the bottom (13) of the propellant charge casing (3). An annular gap (17, 17') is incorporated between the plug (14) and the propellant charge casing (3), which annular gap is led to the outside through the base (13) of the casing. The annular gap (17, 17') is sealed off with respect to the propellant charge (7) by a ring (16) and consists of a fusible, solid and pressure-tight material, the melting point of which lies at least below the melting point of the ignition temperature of the ignition device and the propellant charge (7). If the ammunition (1) is subjected to an excessively high temperature during the transport, storage, etc. thereof, the fusible material of the securing ring (16) begins to liquefy and passes through the annular gap (17, 17') to the outside. As a result of said measure, the plug (14) is released and loses the mechanical hold to the propellant charge casing (3). As a result, the plug (14) exposes the hole (12), so that a larger opening is produced in the base (13) of the casing.

Description

BESCHREIBUNG  DESCRIPTION
Insensitive Munition Insensitive ammunition
Die Erfindung beschäftigt sich mit einer Patronenmunition, insbesondere im Mittelkaliber (beispielsweise 40 mm) und als Übungsmunition, sowie einer einfacher aufgebauten sogenannten Berstsicherung. The invention is concerned with a cartridge ammunition, especially in the middle caliber (for example, 40 mm) and as a training ammunition, as well as a simpler constructed so-called Berstsicherung.
Aus der DE 10 2009 048 365 B3 ist eine patronierte Munition mit einer Berstvorrichtung als Verbindung zwischen Geschoss und Antrieb bekannt. Diese Berstvorrichtung umfasst dabei eine Membran mit wenigstens einer Sollbruchstelle, die sich bei einem vorbestimmten Druck in der Hochdruckkammer des Antriebes öffnet. From DE 10 2009 048 365 B3 a cartridge ammunition with a bursting device is known as a connection between projectile and drive. This bursting device comprises a membrane with at least one predetermined breaking point, which opens at a predetermined pressure in the high-pressure chamber of the drive.
Insbesondere bei einer insensitiven Munition, d.h. einer Munition mit einem insensitiven Antrieb, muss den Forderungen zunehmender Sicherheit immer mehr Rechnung getragen werden. So darf diese nicht explodieren bzw. sich nicht zerlegen, wenn sie beispielsweise einem Feuer oder anderen höheren Temperaturen ausgesetzt wird. Especially with insensitive ammunition, i. an ammunition with an insensitive drive, the demands of increasing security must be increasingly taken into account. For example, it should not explode or disassemble if, for example, it is exposed to fire or other higher temperatures.
Aus der DE 10 2004 020 838 B3 ist eine gattungsgemäße Munition mit einem insensitiven Antrieb bekannt, bei der von der Treibkammer Passagen ausgehen, die die Patronenhülse durchdringen und die mit einem schmelzbaren, festen und druckdichten Material ausgefüllt sind. Die Schmelztemperatur dieses Materials ist dabei niedriger als die Zündtemperatur der pyrotechnischen Zündeinrichtung und der Treibladung. Dadurch wird sichergestellt, dass sichere Transporte auch bei höheren Temperaturen realisiert werden. Durch die Form der Passagen ist zugleich sichergestellt, dass die beim Abschuss auftretenden hohen Gasdrücke trotzdem aufgenommen werden können. From DE 10 2004 020 838 B3 a generic ammunition with an insensitive drive is known, in which go out of the blowing chamber passages which penetrate the cartridge case and which are filled with a fusible, firm and pressure-tight material. The melting temperature of this material is lower than the ignition temperature of the pyrotechnic ignition device and the propellant charge. This ensures that safe transport is realized even at higher temperatures. At the same time, the shape of the passages ensures that the high gas pressures occurring at the time of launch can still be absorbed.
Ausgehend hiervon stellt sich die Erfindung die Aufgabe, eine weitere Möglichkeit für das Einhalten der Sicherheitskriterien auch bei höheren Temperaturen aufzuzeigen. Proceeding from this, the invention has the object to show a further possibility for the compliance with the safety criteria even at higher temperatures.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgezeigt. Der Erfindung liegt die Idee zugrunde, die Patrone mit einer Art lösbaren Verschluss zu versehen, der sich vor der eigentlichen Zündtemperatur des Zündhütchens öffnet, sodass der in der Patrone entstehende Innendruck frühzeitig nach außen entweichen kann. Dieser Explosionsdruck wird durch eine Bohrung, in dem der Verschluss eingebunden ist, im Treibladungsboden entlastet. The object is achieved by the features of claim 1. Advantageous embodiments are shown in the subclaims. The invention is based on the idea to provide the cartridge with a kind of releasable closure, which opens before the actual ignition temperature of the primer, so that the resulting inside the cartridge internal pressure can escape early to the outside. This explosion pressure is relieved through a hole in which the closure is incorporated in the propellant charge floor.
Der Verschluss wird bevorzugt durch einen Metall - Verschlussstopfen gebildet, der zudem das Anzündhütchen aufnimmt. Zwischen dem Verschlussstopfen und der Hülse des insensitiven Antriebs ist ein Ringspalt vorgesehen. Dieser wird durch eine Schmelzsicherung bzw. einem Ring aus schmelzbarem Material gegenüber der Treibladung abgedichtet. Alternativ kann dieses schmelzbare Material auch im Ringspalt eingebracht sein. Kombinationen beider Varianten sind ebenfalls möglich. Wenn die Munition einer vorgegebenen Temperatur unterliegt und die Schmelzsicherung zur Wirkung kommt, wandert der Verschlussstopfen mit dem Anzündhütchen ohne Widerstand nach außen. Dadurch entsteht eine große Öffnung (durch das Freiwerden der Bohrung) im Hülsenboden, wodurch verhindert wird, dass das Treibladungspulver explosionsartig umgesetzt wird und es maximal zu einem langsamen Abbrand kommen kann. The closure is preferably formed by a metal sealing plug, which also receives the primer cap. An annular gap is provided between the sealing plug and the sleeve of the insensitive drive. This is sealed by a fuse or a ring of fusible material to the propellant charge. Alternatively, this fusible material may also be incorporated in the annular gap. Combinations of both variants are also possible. If the ammunition is subject to a predetermined temperature and the fuse comes into effect, moves the plug with the primer without resistance to the outside. This creates a large opening (through the release of the hole) in the sleeve bottom, which prevents the propellant charge powder is exploded and it can come to a maximum slow burn.
Diese Idee realisiert eine in den Kosten geringere Berstsicherung für eine patronierte Munition. Die Schmelzsicherung bzw. der Ring aus schmelzenden, festem und druckdichtem Material, vorzugsweise einem Ostalloy- Ring, kann durch Einpressen und Vernieten in den Hülsenboden eingebracht werden. Die Ostalloy- Sicherung kann ihrerseits aus einer Bismut / Zink Legierung bestehen. Es werden keine Bohrungen in der Treibladungshülse mehr benötigt. Der Ring wiederum kann aus gewalzten Materialstreifen gestanzt werden, ohne dass eine Nachbearbeitung nötig wäre. This idea realizes a lower rupture protection for a cartridged ammunition in the costs. The fuse or the ring of melting, solid and pressure-tight material, preferably a Ostalloy- ring can be introduced by pressing and riveting in the sleeve bottom. The Ostalloy fuse can in turn consist of a bismuth / zinc alloy. There are no longer any holes in the propellant charge case. The ring, in turn, can be stamped from rolled strip of material without the need for reworking.
Anhand eines einfachen Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt: Reference to a simple embodiment with drawing, the invention will be explained in more detail. It shows:

Fig. 2 einen vergrößerten Ausschnitt A aus Fig. 1 , 2 is an enlarged detail A of Fig. 1,
Fig. 3 eine Variante zur Fig. 2.. Fig. 3 shows a variant of FIG .. 2 ..
In Fig. 1 ist eine Munition 1 dargestellt, die ein Geschoss 2 und eine Treibladungshülse 3 aufweist, die mit dem Geschoss 2 bzw. dessen Geschossboden 10 befestigt ist, beispiels- weise über eine Verschraubung 4. Alternative Verbindungen sind Crimpverbindungen, Aufsteck- und Verriegelungsverbindungen etc., wie beispielsweise aus der DE 10 1004 017 464 B4 oder der US 3,645,208 A bekannt. FIG. 1 shows an ammunition 1 which has a projectile 2 and a propellant charge sleeve 3 which is fastened to the projectile 2 or its projectile base 10, for example. Example via a screw 4. Alternative compounds are crimp, Aufsteck- and locking connections, etc., as known for example from DE 10 1004 017 464 B4 or US 3,645,208 A.
In der Treibladungshülse 3 ist ein eine Hochdruckkammer 5 bildender Einsatz (Treibkammer) 6 eingebunden, der zugleich eine (pyrotechnisches) Treibladung 7, hier in Form von Pulver, aufnimmt. Das Treibladungspulver 7 besitzt für ein gutes Zündverhalten Durchzünd- bohrungen 15. Zwischen der Hochdruckkammer 5 und einer unterhalb des Geschossbodens 10 des Geschosses 2 gelegenen Niederdruckkammer 8 sind Überströmöffnungen 9 integriert, die durch den Einsatz geführt sind und von der Hochdruckkammer 5 in die Niederdruckkammer 8 münden. Die Treibladungshülse 3 besteht bevorzugt aus Aluminium und nimmt ein Anzündhütchen 11 in einer Bohrung (Öffnung) 12 am Hülsenboden 13 auf. Das Anzündhütchen 11 selbst ist in einem als Verschluss wirkenden Stopfen 14 integriert, der in die Bohrung (Öffnung) 12 eingesetzt wird. Stopfen 14 und Anzündhütchen 1 1 sind beispielsweise mit einem Ringfugenlack abgedichtet. Die Bohrung 12 ihrerseits sollte bevorzugt zentrisch im Hülsenboden 13 angeordnet sein. Außermittige Einbindungen von Stopfen ohne Anzündhütchen sind auch möglich. In the propellant charge case 3, a high pressure chamber 5 forming insert (drive chamber) 6 is involved, at the same time a (pyrotechnic) propellant charge 7, here in the form of powder, receives. The propellant charge powder 7 has Durchzünd- bores 15. Between the high pressure chamber 5 and located below the floor 10 of the projectile 2 low pressure chamber 8 overflow openings 9 are integrated, which are guided through the insert and open from the high pressure chamber 5 in the low pressure chamber 8 , The propellant charge tube 3 is preferably made of aluminum and takes a Anzündhütchen 11 in a bore (opening) 12 on the sleeve bottom 13. The primer cap 11 itself is integrated in a stopper 14 acting as a closure, which is inserted into the bore (opening) 12. Plug 14 and primer 1 1 are sealed, for example, with a ring joint paint. The bore 12 in turn should preferably be arranged centrally in the sleeve bottom 13. Off center attachments of plugs without primer caps are also possible.
In Hinblick auf die erfinderische Idee wird nunmehr zwischen dem Stopfen 14 und der Treibladungshülse 3 ein Ringspalt 17 vorgesehen, der durch den Hülsenboden nach außen verläuft (Fig.2). Der Ringspalt 17 kann gleichmäßig oder, wie in Fig. 3 dargestellt, sich erweiternd 17' ausgeführt sein und ermöglicht, wenn notwendig, ein kontrolliertes Lösen des Stopfens 14. (Bei der Ringspalterweiterung nach Fig. 3 sollte ein Befestigungsring für einen besseren Halt mit vorgesehen werden.) Anstelle einer herkömmlichen Dichtung wird dann des Weiteren ein schmelzbarer Sicherungsring 16 in die Treibladungshülse 3 eingebracht. Dieser kann an einer Kante 18 am Stopfen 14 vernietet werden. Gleichzeitig kann der Sicherungsring 16 an die Hülse 3 angepresst und verdichtet werden. In view of the inventive idea, an annular gap 17 is now provided between the plug 14 and the propellant charge tube 3, which extends through the sleeve bottom to the outside (Figure 2). The annular gap 17 may be evenly or, as shown in Fig. 3, 17 'extending and allows, if necessary, a controlled release of the plug 14. (In the annular splitter extension of Fig. 3, a mounting ring for better support should be provided In place of a conventional seal then a fusible retaining ring 16 is further introduced into the propellant charge case 3. This can be riveted at an edge 18 on the plug 14. At the same time, the retaining ring 16 can be pressed against the sleeve 3 and compacted.
Die Schmelztemperatur des Materials liegt dabei unterhalb der Zündtemperatur der Zünd- und Treibladung. Unterliegt die Munition 1 bei ihrem Transport, Lagerung etc. einer zu hohen Temperatur, fängt das schmelzende Material des Sicherungsringes 16 an, sich zu verflüssigen und gelangt durch den Ringspalt 17 nach außen. Der Stopfen 14 wird durch diese Maßnahme freigelegt und verliert den mechanischen Halt zur Treibladungshülse 3. Dadurch gibt der Stopfen 14 die Bohrung 12 frei, sodass eine größere Öffnung im Hülsenboden 13 entsteht. Beim Abschuss der Munition aus einem Waffenrohr (nicht näher dargestellt) stützen sich der Stopfen 14, das Anzündhütchen 11 und die Treibladungshülse 3 gegen einen Waffenver- schluss (nicht näher dargestellt) ab, sodass sichergestellt ist, dass der Stopfen 14 beim Abschuss nicht aus der Bohrung 12 herausgedrückt werden kann. Der Sicherungsring 16 nimmt seinerseits den beim Abschuss der Munition 1 im normalen Gebrauch auf diese Sicherung bzw. diesen Ring 16 wirkenden Gasdruck (von ca. 3000 bar) auf und dichtet den Ringspalt 17 zur Treibladung 7 hin ab, sodass der Ring 16 in seiner Doppelfunktion hier als Dichtungsring fungiert. The melting temperature of the material is below the ignition temperature of the ignition and propellant charges. Subjecting the ammunition 1 in their transport, storage, etc. too high a temperature, the melting material of the retaining ring 16 begins to liquefy and passes through the annular gap 17 to the outside. The plug 14 is exposed by this measure and loses the mechanical support to the propellant charge shell 3. Thus, the plug 14, the bore 12 is free, so that a larger opening in the sleeve bottom 13 is formed. When firing the ammunition from a gun barrel (not shown in detail), the stopper 14, the primer cap 11 and the propellant charge shell 3 are supported against a weapon closure (not shown in detail), so that it is ensured that the stopper 14 does not escape from the body during firing Hole 12 can be pushed out. The circlip 16 in turn takes on the firing of the ammunition 1 in normal use on this fuse or ring 16 acting gas pressure (from about 3000 bar) and seals the annular gap 17 from the propellant charge 7 down, so that the ring 16 in its dual function here acts as a sealing ring.
