Description

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

Zur Reduzierung des Totlastanteils, insbesondere bei patronierter Munition, ist es aus der US-PS-2 991 168 sowie aus der DE-AI-2 424 900 bereits bekannt, die Treibladungshülse - zumindest teilweise - aus einem verbrennbaren Material herzustellen. Im Gegensatz zu herkömmlichen, vollständig aus Metall bestehenden Treibladungshülsen, umfaßt eine solche Hülse höchstens noch einen ggf. wiederverwendbaren Hülsenboden aus Metall. Die Herstellung der verbrennbaren Hülsenteile erfolgt jedoch in einem komplexen, mehrschrittigen und daher teuren Verfahren und ergibt zudem einen Hülsenwerkstoff mit einer unbefriedigenden mechanischen Festigkeit.To reduce the dead load component, in particular in the case of ammunition with cartridges, it is already known from US Pat. No. 2,991,168 and from DE-AI-2,424,900 to produce the propellant charge sleeve, at least partially, from a combustible material. In contrast to conventional propellant charge sleeves made entirely of metal, such a sleeve comprises at most one possibly reusable sleeve base made of metal. However, the combustible sleeve parts are produced in a complex, multi-step and therefore expensive process and also result in a sleeve material with an unsatisfactory mechanical strength.

Der Erfindung liegt die Aufgabe zugrunde, eine Treibladungshülse anzugeben, die besonders einfach herstellbar ist und die daher die Laborierung von Treibladungen, insbesondere auch die Laborierung von patronierter Munition stark vereinfacht und verbilligt.The invention is based on the object of specifying a propellant charge sleeve which is particularly simple to produce and which therefore greatly simplifies and reduces the cost of laboring propellant charges, in particular also of the cartridge ammunition.

Diese Aufgabe wird durch die in Patentanspruch 1 angegebene Erfindung gelöst.This object is achieved by the invention specified in claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous refinements and developments of the invention emerge from the subclaims.

Die Erfindung wird nachfolgend unter Bezug auf die Zeichnung näher erläutert. Dabei zeigt:

  • Fig. 1: eine großkalibrige patronierte Munition in Seitenansicht;
  • Fig.2: einen Querschnitt durch einen Teil der Treibladungshülse;
  • Fig.3: einen Querschnitt durch ein weiteres Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Treibladungshülse.
  • Fig. 4: einen Querschnitt durch eine modulartig ausgestaltete Treibladung.
The invention is explained in more detail below with reference to the drawing. It shows:
  • Fig. 1: a large-caliber cartridge ammunition in side view;
  • 2 shows a cross section through part of the propellant charge sleeve;
  • 3 shows a cross section through a further exemplary embodiment of a propellant charge sleeve designed according to the invention.
  • 4 shows a cross section through a propellant charge designed in a modular manner.

Fig. 1 zeigt in schematischer Darstellung in einer Seitenansicht eine großkalibrige patronierte Munition 10 mit einem Geschoß 12, einem aus Metall bestehenden Hülsenboden 13 und einer verbrennbaren Hülse 11 sowie einer aus einem elastischen Material bestehenden Liderung 14. Erfindungsgemäß besteht die Treibladungshülse 11 aus einer verbrennbaren Kunststoffolie 20, die das in Fig. 1 nicht sichtbare Treibladungspulver mantelförmig umhüllt und die einerseits mit dem Geschoß 12 und andererseits mit dem Hülsenboden 13 fest verbunden ist.Fig. 1 shows a schematic representation in a side view of a large-caliber cartridge ammunition 10 with a projectile 12, a sleeve base 13 made of metal and a combustible sleeve 11 and an eyelet 14 made of an elastic material. According to the invention, the propellant charge sleeve 11 consists of a combustible plastic film 20, which envelops the propellant charge powder, which is not visible in FIG. 1, and which is firmly connected on the one hand to the projectile 12 and on the other hand to the sleeve base 13.

Besonders vorteilhaft ist die Kunststoffolie 20 als Schrumpffolie ausgeführt, die unter Wärmeeinfluß stark schrumpft, dabei das eingehülfte Treibladungspulver stark zusammenpreßt und auf diese Weise für eine hervorragende mechanische Festigkeit des Treibladungsaufbaus sorgt. Im Vergleich zu einem locker eingefüllten Pulver ist dadurch auch eine wesentlich größere Ladedichte zu erreichen, die innenballistische Vorteile bringt.The plastic film 20 is particularly advantageously designed as a shrink film, which shrinks considerably under the influence of heat, thereby compressing the enveloped propellant powder strongly and in this way ensures excellent mechanical strength of the propellant charge build-up. Compared to a loosely filled powder, this also enables a significantly higher loading density to be achieved, which brings internal ballistic advantages.

In einem weiteren weiteren Ausführungsbeispiel der Erfindung wird eine im Bereich der Nahrungsmittelverpackung an sich bekannte Methode angewendet, indem nach Einhüllung des Treibladungspulvers mit der Folie 20 durch Anschluß einer Vakuumpumpe Luft abgesaugt wird. Auch dadurch legt sich die Folie 20 eng an das eingehüllte Treibladungspulver an, wodurch ein ähnlich stabiler Aufbau entsteht, wie bei Verwendung einer Schrumpffolie.In a further further exemplary embodiment of the invention, a method which is known per se in the field of food packaging is used in that, after the propellant charge powder has been enveloped in the film 20, air is sucked out by connecting a vacuum pump. This also causes the film 20 to lie closely against the enveloped propellant charge powder, which results in a structure which is similarly stable as when using a shrink film.

Als weitere Laboriermöglichkeit bietet sich ein Einpressen des Treibladungspulvers in die aus einer Kunststoffolie 20 bestehende Treibladungshülse 11 an. Dazu wird die Treibladungshülse 11 zweckmäßig in eine Preßform eingebracht, an deren Innenwandung sie sich während des Füllvorgangs abstützt. Auch bei dieser Laborierungsart läßt sich eine höhere Ladedichte, verbunden mit einer Verbesserung der mechanischen Stabilität des Treibladungsaufbaues erreichen.Pressing the propellant charge powder into the propellant charge sleeve 11, which is made of a plastic film 20, is another laboratory option. For this purpose, the propellant charge sleeve 11 is expediently introduced into a mold, on the inner wall of which it is supported during the filling process. With this type of laboratory, too, a higher charge density can be achieved, combined with an improvement in the mechanical stability of the propellant charge build-up.

Besonders gut geeignet sind Kunststoffolien, die durch Sauerstoffträger auf ein gewünschtes Abbrandverhalten eingestellt sind. Beispielsweise eignen sich Kunststoffolien aus Polyäthylen, Polyurethan, Polyisobutylen, Polybutadien sowie Polysulfiden.Plastic films that are set to a desired burn-off behavior by oxygen carriers are particularly suitable. For example, plastic films made of polyethylene, polyurethane, polyisobutylene, polybutadiene and polysulfides are suitable.

Als Sauerstoffträger sind besonders gut geeignet Lithiumnitrat, Lithiumchlorat, Natriumnitrat, Natriumperchlorat, Kaliumnitrat, Kaliumperchlorat, Ammonnitrat, Ammonperchlorat, Ammonchlorat, Hydrazinnitrat, sowie organische Peroxide, insbesondere Dibenzolperoxid, Nitrylperchlorat, Hexanitroäthan.Lithium nitrate, lithium chlorate, sodium nitrate, sodium perchlorate, potassium nitrate, potassium perchlorate, ammonium nitrate, ammonium perchlorate, ammonium chlorate, hydrazine nitrate and organic peroxides, in particular dibenzene peroxide, nitryl perchlorate, hexanitroethane, are particularly suitable as oxygen carriers.

Auch kombinierte Sauerstoffträger, wie beispielsweise Bor/ Kaliumnitrat, Zirkon/Bariumnitrat sowie Mischungen der Metalle Magnesium, Bor und Aluminium mit den vorstehend genannten Oxidatoren sind für die Treibladungshülse besonders geeignet.Combined oxygen carriers such as boron / potassium nitrate, zirconium / barium nitrate and mixtures of the metals magnesium, boron and aluminum with the oxidizers mentioned above are also particularly suitable for the propellant charge sleeve.

Von den vorgenannten organischen Peroxiden und den kombinierten Sauerstoffträgern können bis zu 50 %, am zweckmäßigsten zwischen 10 bis 20 %, in der Kunststoffolie enthalten sein.Up to 50%, most suitably between 10 to 20%, of the aforementioned organic peroxides and the combined oxygen carriers can be contained in the plastic film.

Falls erforderlich, kann in einem weiteren Ausführungsbeispiel der Erfindung die Stabilität der Treibladungshülse noch dadurch vergrößert werden, daß die Kunststoffolie 20, wie das in Fig. 3 gezeigte Querschnittsbild einer Treibladungshülse 11 zeigt, mit einer äußeren Beschichtung 21' aus Polyurethan bedeckt wird. Um die Verbrennbarkeit auch dieser äußeren Schicht 21' zu steigern, wird diese zweckmäßig mit einer Mischung aus z. B. Bor-Kaliumnitrat oder anderen vorgenannten Sauerstoffträgern versetzt.If necessary, in a further exemplary embodiment of the invention, the stability of the propellant charge sleeve can be increased further by covering the plastic film 20 with an outer coating 21 'made of polyurethane, as the cross-sectional image of a propellant charge sleeve 11 shown in FIG. 3 shows. In order to increase the combustibility of this outer layer 21 ', this is expediently mixed with a mixture of e.g. B. boron potassium nitrate or other aforementioned oxygen carriers.

Wenngleich die Erfindung vorstehend hauptsächlich anhand einer großkalibrigen Patronenmunition erläutet worden ist, läßt sie sich mit gleich gutem Erfolg und entsprechenden Einsparungsmögtichkeiten auch bei kleinkalibriger Munition und zur Umhüllung von Treibladungen für Artilleriegeschosse einsetzen.Although the invention has been explained above primarily on the basis of large-caliber cartridge ammunition, it can also be used with equally good success and corresponding savings possibilities also with small-caliber ammunition and to encase propellant charges for artillery shells.

Abgesehen von der stark vereinfachten Herstellung bietet die Erfindung auch noch weitere Vorteile, da durch Auswahl gas- und feuchtigkeitsdichter Folienmaterialien die Lagerfähigkeit laborierter Treibladungen gesteigert werden kann.In addition to the greatly simplified production, the invention also offers further advantages, since the selection of gas-tight and moisture-tight film materials increases the storability of propellant charges that have been laboratoryized can.

Bei Verwendung durchsichtiger Folien oder zumindest teilweise durchsichtiger Folien ist es zudem möglich, den Zustand der laborierten Treibladung ohne Zerstörung der Treibladungshülse zu überprüfen.If transparent foils or at least partially transparent foils are used, it is also possible to check the condition of the propellant charge in laboratory without destroying the propellant charge sleeve.

In einem Ausführungsbeispiel der Erfindung wird patronierte Munition (Fig. 1) mit der erfindungsgemäß als Folie 20 ausgestalteten Treibladungshülse 11 ausgestattet. Die Folie 20 liegt dazu in Form eines Schlauchs vor, der einerseits am Heck des Geschosses 12 und andererseits am Hülsenboden 13 befestigt ist. Diese Befestigungen können vorzugsweise durch Kleben oder Verschweißen, ggf. auch durch Verschrauben, Verspritzen oder durch einen Schrumpfsitz der Folie herbeigeführt werden. Ggf. läßt sich gleichzeitig mit der Befestigung der Folie 20 am Hülsenboden 13 die Liderung anbringen. Im Anschluß daran kann die Treibladung in die Treibladungshülse 11 eingebracht werden. Schüttpulver läßt sich zweckmäßig durch die im Hülsenboden 13 vorgesehene Öffnung für den Treibladungsanzünder einfüllen, während Röhrenpulver vor der Befestigung des Hülsenbodens 13 in die Treibladungshülse 11 einzufüllen ist. Anschließend wird die Treibladungshülse 11 geschrumpft bzw. evakuiert. Beim Evakuieren kann wiederum die Öffnung des Treibladungsanzünders zum Absaugen der Luft verwendet werden.In one embodiment of the invention, cartridge-type ammunition (FIG. 1) is equipped with the propellant charge sleeve 11, which is designed according to the invention as a film 20. For this purpose, the film 20 is in the form of a hose which is fastened on the one hand to the rear of the projectile 12 and on the other hand to the sleeve base 13. These fastenings can preferably be brought about by gluing or welding, possibly also by screwing, spraying or by shrink fit of the film. Possibly. the eyelid can be attached simultaneously with the fastening of the film 20 to the sleeve base 13. The propellant charge can then be introduced into the propellant charge sleeve 11. Bulk powder can advantageously be filled through the opening provided in the sleeve base 13 for the propellant charge lighter, while tube powder is to be filled into the propellant charge sleeve 11 before the sleeve base 13 is fastened. The propellant charge sleeve 11 is then shrunk or evacuated. When evacuating, the opening of the propellant lighter can be used to extract the air.

Im Vergleich zu herkömmlichen, aus Metall bestehenden Treibladungshülsen zeigt die durch Schrumpfen bzw. Evakuieren fertiggestellte Treibladungshülse 11 eine stark unregelmäßige äußere Form. Dies erweist sich jedoch innenballistisch als Vorteil, da hierdurch die Verbrennung der Folie 20 erleichtert wird.In comparison to conventional propellant charge sleeves made of metal, the propellant charge sleeve 11, which is completed by shrinking or evacuating, has a highly irregular external shape. However, this proves to be an advantage from the inside ballistic point of view, since this facilitates the combustion of the film 20.

Ein weiteres Ausführungsbeispiel der Erfindung wird anhand von Fig. 4 erläutert. Hierbei handelt es sich um eine modulartig aufgebaute Treibladung 40, bei der Treibladungsanteile 43 portionsweise voneinander getrennt in einem Schrumpfschlauch 42 angeordnet sind. Die Treibladungsportionen 43 sind wiederum in einer ebenfalls aus Kunststoffolie bestehenden äußeren Hülle 41 untergebracht.Another exemplary embodiment of the invention is explained with reference to FIG. 4. This is a propellant charge 40 of modular construction, in which propellant charge portions 43 are arranged in portions in a shrink tube 42 separated from one another. The propellant charge portions 43 are in turn housed in an outer shell 41, which is also made of plastic film.

Je nach Bedarf sind alle in einer Hülle 41 angeordneten Treibladungen 43 gleichzeitig zu verwenden oder nur teilweise. Dazu ist die äußere Hülle 41 leicht aufreißbar ausgebildet, so daß eine beliebige Anzahl nicht benötigter Treibladungen 43 herausgenommen werden kann. Um die Trennung voneinander zu erleichtern, sind die Verbindungsstücke 44 zwischen den die Treibladungen 43 einhüllenden Folienhüllen perforiert und damit leicht abtrennbar.Depending on requirements, all propellant charges 43 arranged in a shell 41 can be used simultaneously or only partially. For this purpose, the outer shell 41 is designed to be easy to tear open, so that any number of propellant charges 43 that are not required can be removed. In order to facilitate the separation from one another, the connecting pieces 44 are perforated between the foil casings enveloping the propellant charges 43 and are therefore easily detachable.

Um die Handhabbarkeit derartiger Treibladungen, insbesondere im Hinblick auf die auszuwählende Treibladungsmenge zu erleichtern, können die die Treibladungen 43 einhüllenden Schlauchstücke 42 zweckmäßig mit unterschiedlichen Farben und/oder einem Aufdruck, z. B. einer Zahlenangabe gekennzeichnet sein.In order to facilitate the handling of such propellant charges, in particular with regard to the amount of propellant charge to be selected, the hose pieces 42 enveloping the propellant charges 43 can expediently be provided with different colors and / or an imprint, e.g. B. be marked with a number.

Selbstverständlich ist es - analog zu der in Fig. 1 beschriebenen patronierten Munition - auch bei getrennten Ladungen möglich, eine besondere, etwa einem Treibladungsraum angepaßte Formgebung der aus Folie bestehenden Treibladungshülse zu erreichen. Auf einfachste Weise gelingt dies dadurch, daß man die Folie für den Abfüllvorgang in eine dem Ladungsraum angepaßte Form einbringt.Of course, analogous to the cartridge ammunition described in FIG. 1, it is also possible with separate loads to achieve a special shape of the propellant charge sleeve, which is adapted to a propellant charge space. The simplest way to do this is to place the film for the filling process in a shape adapted to the cargo space.
