Description

Die Erfindung betrifft einen Treibladungsbehälter bzw. eine Treibladungshülse gemäß den Merkmalen des Oberbegriffs des Anspruchs 1. Sowie ein Verfahren zu dessen Herstellung gemäß Oberbegriff des Anspruchs 4.The invention relates to a propellant charge container or a propellant charge sleeve according to the features of the preamble of claim 1. As well as a method for its production according to the preamble of claim 4.

Aus der DE-A-35 44 927 ist eine übliche Metallkartusche mit eingeklebter Additivmanschette, bestehend aus beschichtetem Leinengewebe, Polyäthylenfolie und Kunstseide bekannt. Das Leinengewebe ist mit einer Mischung aus Wachs und Titandioxid TiO₂ beschichtet und zur Innenseite zum Schutz gegen Abrieb durch Treibladungs-Pulverkörner mit der Kunststoffolie und der weiteren Textilschicht abgedeckt. Mit dieser besonderen Ausbildung der mehrschichtigen Additivmanschette soll bei einer mechanischen Beanspruchung bei hohen Temperaturen eine Phlegmatisierung des Pulvers durch Wachsabrieb verhindert werden. Die Treibladungsteilchen können danach an der Kunstseide entlanggleiten, ohne die Manschette zu beschädigen. Nachteilig bei dieser bekannten Additivmanschette ist, daß Probleme bei der Umsetzung der aus mehreren Schichten bestehenden Additivmanschette auftreten und nicht zulässige Rückstände im Rohr verbleiben können.
Die auf die Additivmanschette aufgetragene Mischung aus Wachs und Titandioxid wirkt auf die Innenseite der nichtverbrennbaren Metallhülse, eine besondere Wirkung auf das Waffenrohr ist kaum zu erwarten. Verbrennungsrückstände treten insbesondere dadurch auf, daß in der Außenseite der Manschette keine ausreichend hohen Zündtemperaturen erreicht werden, da die Wärme hier von der Metallhülse aufgenommen und abgeführt wird (Kühleffekt der Metallhülse).From DE-A-35 44 927 a conventional metal cartridge with a glued-in additive sleeve is known, consisting of coated linen fabric, polyethylene film and synthetic silk. The linen fabric is coated with a mixture of wax and titanium dioxide TiO₂ and is covered on the inside with plastic film and the other textile layer to protect it from abrasion by propellant powder grains. This special design of the multi-layer additive sleeve is intended to prevent the powder from being desensitized by wax abrasion when subjected to mechanical stress at high temperatures. The propellant particles can then slide along the artificial silk without damaging the cuff. A disadvantage of this known additive sleeve is that problems arise in the implementation of the additive sleeve consisting of several layers and unacceptable residues can remain in the tube.
The mixture of wax and titanium dioxide applied to the additive sleeve acts on the inside of the non-combustible metal sleeve, a special effect on the weapon barrel is hardly to be expected. Combustion residues occur in particular in that in the outside of the Cuff cannot reach sufficiently high ignition temperatures because the heat is absorbed and dissipated by the metal sleeve (cooling effect of the metal sleeve).

Aus der den nächsten Stand der Technik bildenden US-A-3148620 sind Treibladungshülsen, insbesondere aus Metall, bekannt, bei denen auf die Innenseite der Hülse als Additiv eine Beschichtung bzw. Mischung aus Wachs und Titandioxid TiO₂ direkt durch Spachteln, Streichen, Spritzen oder ähnlichem ohne zusätzliche Trägermaterialien aufgetragen wird. Nachteilig ist bei Verwendung derartiger Additive, daß bei hohen Temperaturen eine ungewünschte Phlegmatisierung des an das Additiv angrenzenden Treibladungspulvers erfolgt, die eine stark ungleichmäßige Innen- und Außenballistik verursacht. Außerdem macht sich auch bei diesen Treibladungshülsen der oben erwähnte Kühleffekt der Metallhülse störend bemerkbar.From the closest prior art US-A-3148620 propellant charge sleeves, in particular made of metal, are known in which a coating or mixture of wax and titanium dioxide TiO₂ directly by filling, brushing, spraying or the like on the inside of the sleeve as an additive is applied without additional carrier materials. A disadvantage of using such additives is that, at high temperatures, the propellant charge powder adjacent to the additive is undesirably phlegmatized, which causes a highly uneven interior and exterior ballistics. In addition, the above-mentioned cooling effect of the metal sleeve is also noticeable with these propellant charge cases.

Es ist Aufgabe der Erfindung, einen Treibladungsbehälter bzw. eine Treibladungshülse anzugeben, bei deren Umsetzung im Waffenrohr sowohl Verbrennungsrückstände als auch eine Phlegmatisierung des an das Additiv angrenzenden Pulvers vermieden wird. Die rohrschonende und erosionsmindernde Wirkung soll insbesondere bei großkalibrigen Artilleriewaffen und der Verwendung von modularen Treibladungen wesentlich erhöht werden. Bei Verwendung von modularen Treibladungsbehältern soll trotz höherem Ladungsgewicht keine höhere Erosion auftreten als bei eingeführten Ladungssystemen.It is an object of the invention to provide a propellant charge container or a propellant charge sleeve, the implementation of which in the gun barrel prevents both combustion residues and phlegmatization of the powder adjacent to the additive. The pipe-protecting and erosion-reducing effect is to be significantly increased, especially with large-caliber artillery weapons and the use of modular propellant charges. If modular propellant charge containers are used, no higher erosion should occur despite the higher charge weight than with imported charge systems.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine direkt auf ein verbrennbares Hülsenmaterial aufgetragene Beschichtung aus Wachs und TiO₂ zur Pulverseite hin mit einer dünnen Metallfolie abgedeckt ist. Die Metallfolie weist eine Stärke von kleiner 0,5 mm, vorzugsweise etwa 0,05 mm, auf und besteht aus einem Metall bzw. einer Metallegierung aus der Elementengruppe Blei, Zink, Aluminium, Magnesium, Eisen, Nickel, Silber, Molybdän oder einem entsprechend geeigneten Metall. Die Folie verhindert zum einen eine Phlegmatisierung bzw. Passivierung der anliegenden Treibladungskörner durch die Beschichtung, zum anderen wird eine unerwünschte Rohrverkupferung (z.B. aufgrund der Führungsbändern der Geschosse) verhindert bzw. vermindert.This object is achieved in that a directly applied to a combustible sleeve material coating of wax and TiO₂ to the powder side with a thin metal foil is covered. The metal foil has a thickness of less than 0.5 mm, preferably about 0.05 mm, and consists of a metal or a metal alloy from the element group lead, zinc, aluminum, magnesium, iron, nickel, silver, molybdenum or a corresponding one suitable metal. On the one hand, the film prevents phlegmatization or passivation of the adjacent propellant grains by the coating, and on the other hand prevents or reduces unwanted copper-plating (eg due to the guiding bands of the projectiles).

Die Erfindung wird nachfolgend anhand von zwei in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert und beschrieben.The invention is explained and described in more detail below with reference to two exemplary embodiments shown in the drawings.

  • Figur 2 einen vollständigen Treibladungsbehälter gemäß der Erfindung,
  • Figur 3 eine teilverbrennbare Treibladungshülse gemäß der Erfindung und
  • Figur 4 einen vergrößerten Ausschnitt X der Treibladungsbehälter - bzw. Hülsenwandung mit der erfindungsgemäßen Beschichtung.

In Figur 1 und Figur 2 ist mit der Bezugsziffer 10 ein modulares Treibladungsmodul für eine 155 mm Artilleriewaffe bezeichnet. Das Treibladungsmodul 10 besteht aus einer Oberschale 12 und einer Unterschale 14, z. B. aus verpreßtem und geformtem Nitrozellulosepapier. Die zylindrische Innenfläche 18 der Oberschale 12 und Unterschale 14 ist jeweils mit einer Beschichtung aus Wachs und Titandioxid TiO₂ versehen. In einem mittleren Verbindungsbereich 24 sind die Oberschale 12 und die Unterschale 14 miteinander verklebt. Der Schalenboden 20 der Unterschale 14 und der Schalendeckel 22 der Oberschale 12 weisen mittig jeweils einen nach innen weisenden Ringflansch 34 zur Fixierung eines als zentrales Anzündelement ausgebildeten Rohrstükkes 32 auf.In FIG. 1 and FIG. 2, reference number 10 denotes a modular propellant charge module for a 155 mm artillery weapon. The propellant charge module 10 consists of an upper shell 12 and a lower shell 14, for. B. from pressed and shaped nitrocellulose paper. The cylindrical inner surface 18 of the upper shell 12 and lower shell 14 is each provided with a coating of wax and titanium dioxide TiO₂. The upper shell 12 and the lower shell 14 are glued to one another in a central connecting region 24. The shell bottom 20 of the lower shell 14 and the shell cover 22 of the upper shell 12 each have an inwardly facing annular flange 34 for fixing a pipe piece 32 designed as a central ignition element.

Das Treibladungsmodul 10 ist mit einem pulver- oder granulatförmigen Treibladungsmittel 26 gefüllt. Zum Einfüllen des Treibladungsmittels 26 in das fertige Treibladungsmodul 10 weist der Schalendeckel 22 der Oberschale 12 z. B. eine dezentrale Einfüllöffnung 28 auf, die nach dem Einfüllen des Treibladungsmittels 26 mit einem angeklebten Verschlußdeckel 30 gegen Umwelteinflüsse gasdicht verschlossen wird.The propellant charge module 10 is filled with a powder or granular propellant 26. To fill the propellant 26 in the finished propellant module 10, the shell cover 22 of the upper shell 12 z. B. a decentralized filler opening 28, which is sealed gas-tight against environmental influences after the filling of the propellant 26 with a glued closure cover 30.

In Figur 3 ist eine verbrennbare Treibladungshülse 40 für ein unterkalibriges mit Leitwerk 52 ausgestattetes Wuchtgeschoß 50 dargestellt. Die Treibladungshülse 40 weist ein zylindrisches Hülsenteil 44, nach oben zur Geschoß- bzw. Treibkäfigabstützung einen kegelförmigen Deckel 42 und rückseitig bzw. bodenseitig eine nichtverbrennbare Stummelhülse 58, z. B. aus Metall oder Kunststoff, mit Primer 56 (Anzündröhrchen) auf. Im Verbindungsbereich 54 ist der kegelförmige Deckel 42 mit dem zylindrischen Hülsenteil 44 verklebt.FIG. 3 shows a combustible propellant charge sleeve 40 for a sub-caliber balancing projectile 50 equipped with an empennage 52. The propellant charge sleeve 40 has a cylindrical sleeve part 44, a conical cover 42 for projectile or sabot support and a non-combustible stub sleeve 58, e.g. B. made of metal or plastic, with primer 56 (igniter tube). In the connection area 54, the conical cover 42 is glued to the cylindrical sleeve part 44.

Die zylindrische Innenfläche 48 der Treibladungshülse 40, wie auch die Innenfläche des kegelförmigen Deckels 42 sind mit einer Beschichtung 46 aus Wachs und Titandioxid TiO₂ belegt. Die Beschichtung 46 kann die gesamte Innenfläche 48 der Treibladungshülse 40 bedecken oder, wie in Figur 3 dargestellt ist, auch nur zonen- oder bereichsweise vorgesehen sein. Die Treibladungshülse 40 ist vollständig mit Treibladungspulver gefüllt. Um einen direkten Kontakt von Treibladungspulverkörnern und der Beschichtung 46 zu vermeiden (Abrieb der Beschichtung und Passivierung der Pulverkörner), ist die Beschichtung 46 nach innen mit einer aufgeklebten oder aufgedrückten dünnen Metallfolie 38 abgedeckt, die in der vergrößerten Teildarstellung X in Figur 4 gezeigt ist. Die Metallfolie 38 weist eine Stärke von kleiner 0,5 mm, vorzugsweise etwa 0,05 mm, auf. Wachs dient bei der Zündung des Treibladungsmoduls bzw. der Treibladungshülse bei einer Relativbewegung der verbrennenden Treibladungshülsenwandung bzw. der einzelnen Pulverkörner als Gleitmittel; das Titandioxid senkt die Verbrennungsspitzentemperaturen des Treibladungspulvers im Bereich der Rohrwandung; dadurch wirken die Bestandteile der Beschichtung (16, 46) erosionsmindernd und verlängern die nutzbare Lebensdauer der Waffe. Die Metallfolie 38 verhindert eine unerwünschte Rohrverkupferung; die Kupferablagerungen können sich aus den Führungsbändern der Geschosse bilden. Die Metallfolie, vorzugsweise eine Bleifolie, könnte auch durch eine andere dünne Folie aus einer Metallegierung, z. B. aus Aluminiumlegierung mit Magnesiumbestandteilen oder anderen Leichtmetallen, ersetzt werden.The cylindrical inner surface 48 of the propellant charge sleeve 40, as well as the inner surface of the conical cover 42 are covered with a coating 46 of wax and titanium dioxide TiO₂. The coating 46 can cover the entire inner surface 48 of the propellant charge sleeve 40 or, as shown in FIG. 3, can also be provided only in zones or regions. The propellant charge sleeve 40 is completely filled with propellant charge powder. In order to avoid direct contact of propellant charge powder grains and the coating 46 (abrasion of the coating and passivation of the powder grains), the coating 46 is covered on the inside with a glued or pressed-on thin metal foil 38, which is shown in the enlarged partial view X in FIG. The metal foil 38 has a thickness of less than 0.5 mm, preferably about 0.05 mm. Wax serves as a lubricant in the ignition of the propellant charge module or the propellant charge sleeve during a relative movement of the burning propellant charge sleeve wall or the individual powder grains; the titanium dioxide lowers the combustion peak temperatures of the propellant powder in the area of the tube wall; As a result, the components of the coating (16, 46) reduce erosion and extend the usable life of the weapon. The metal foil 38 prevents unwanted copper plating; the copper deposits can come out of the guiding bands of the projectiles form. The metal foil, preferably a lead foil, could also be replaced by another thin foil made of a metal alloy, e.g. B. made of aluminum alloy with magnesium components or other light metals to be replaced.

Insgesamt wird mit der Erfindung also eine spürbare Schonung und Verlängerung der Lebensdauer des Waffenrohes erzielt.Overall, a noticeable protection and extension of the life of the gun barrel is achieved with the invention.
