Abstract

Hitherto known ignition transmission charges can be used to only a restricted extent because of their impact sensitivity to extreme loads such as occur as a result of acceleration processes during the feed of propellent-charge modules in high-calibre mortars, preferably guns. The new ignition transmission charge will withstand extreme impact loads and, furthermore, guarantee a likewise advantageous full ignition, and the supporting tube encasing the ignition charge will contribute to increasing the energy balance. …<??>For this purpose, the ignition transmission charge 1 for a propellent charge 16 arranged in a propellent-charge module 14 consists of a high-energy propellent-charge powder with a heat quantity of 3 kJ/g to 4.5 kJ/g and a supporting tube 2 encasing the ignition transmission charge and consisting of normal compression-moulded propellent-charge powder. The ignition transmission charge 1 and supporting tube 2 are coaxially arranged mirror-symmetrically and rotationally symmetrically inside the propellent-charge module 14 and form at least one free ignition channel 17. The ignition transmission charge 1 can, for example, be connected as an extruded tube 4 to the supporting tube 2 or be designed as a foil adhesively bondable to the inner face of the supporting tube or, for example, be injected directly onto the inner face of the supporting tube 2. To achieve a higher ignition sensitivity, the inner face of the ignition transmission charge 1 is provided, for example, with longitudinal or transverse grooves. By means of this connection together with the supporting tube 2, the ignition transmission charge, in a layer thickness s of between 1 mm and 10 mm set in relation to the diameter and length of the ignition channel 17, withstands extreme impact loads during the feed of propellent-charge modules. …<IMAGE>…

Description

Die Erfindung betrifft eine Anzündübertragungsladung für eine Treibladung nach demn Oberbegriff des Patent­anspruches 1.The invention relates to an ignition transfer charge for a propellant charge according to the preamble of claim 1.

Eine derartige vorzugsweise für Treibladungsmodule ein­setzbare Anzündübertragungsladung ist aus der DE-34 32 291 A 1 bekannt. Diese Anzündübertragungsladung kann dabei in einer Ausführungsvariante aus gestapelten Einzelringen hergestellt sein, welche durch ein ver­brennbares Rohr zentriert werden und beispielsweise aus Borkaliumnitratpulver oder in einer weiteren Aus­führungsvariante, beispielsweise aus rohrartig strangge­preßter poröser Nitrozellulose bestehen kann. Die aus den vorgenannten oder vergleichbaren Stoffen bestehende Anzündübertragungsladung ist spiegel- und rotations­symmetrisch am Treibladungsmodul angeordnet, wodurch das Treibladungsmodul in axialer Richtung beliebig von jeweils einer Stirnseite anzündbar ist und sich deshalb vorzüg­lich für automatische Ladevorgänge eignet. Unter extremen Belastungen, wie sie beispielsweise bei schlagartigen Beschleunigungsvorgängen auftreten, können jedoch z. B. stoßempfindliche Anzündübertragungsladungen in ihrer Stabilität aufgrund ihrer vergleichsweise geringen me­chanischen Festigkeit beeinträchtigt werden.Such an ignition transfer charge, which can preferably be used for propellant charge modules, is known from DE-34 32 291 A1. This kind of ignition transfer charge can be produced in one embodiment from stacked individual rings which are centered by a combustible tube and can consist, for example, of boron potassium nitrate powder or in a further embodiment, for example from tubular extruded porous nitrocellulose. The ignition transfer charge consisting of the aforementioned or comparable substances is arranged in a mirror-symmetrical and rotationally symmetrical manner on the propellant charge module, as a result of which the propellant charge module can be ignited from any end face in the axial direction and is therefore particularly suitable for automatic charging processes. Under extreme loads, such as occur during sudden acceleration processes, however, z. B. shock-sensitive ignition transmission charges are impaired in their stability due to their comparatively low mechanical strength.

Aufgabe der Erfindung ist es, eine Anzündübertragungsla­dung zu schaffen, die extremen Stoßbelastungen Stand hält und desweiteren eine ebenfalls günstige Durchzün­dung gewährleistet sowie bei der das Stützrohr zur Erhöhung der Energiebilanz der Treibladung beiträgt.The object of the invention is to provide an ignition transfer charge which withstands extreme shock loads and furthermore also ensures a favorable ignition and also in which the support tube contributes to increasing the energy balance of the propellant charge.

Durch den Einsatz von rohrförmig formgepreßtem Treibla­dungspulver als Anzündübertragungsladung und als Stütz­rohr der Anzündübertragungsladung wird vorzugsweise bei automatisch dem Ladungsraum einer großkalibrigen Rohrwaf­fe zugeführten Treibladungsmodulen die Möglichkeit er­öffnet, eine vergleichsweise hochenergetische Anzünd­übertragungsladung mit einer Wärmemenge von 3 kJ/g bis 4,5 kJ/g zur Anzündung der im Treibladungsmodul befind­lichen Treibladung zu verwenden und ein Stützrohr aus stranggepreßtem Treibladungspulver zur Erhöhung der Ener­giebilanz einzusetzen. In vorteilhafter Weise ermöglicht dabei die Zusammensetzung der hochenergetischen Anzündüber­tragungsladung von Nitrozellulose mit 20 % bis 50 % Nitroglyzerin eine günstige Voraussetzung einerseits für eine hohe Abbrandgeschwindigkeit und andererseits für eine fertigungstechnisch einfach, präzise und stabil herstellbare Anordnung an der Innenseite eines rohrartigen Trägers aus an sich gebräuchlichem und in gepreßter Form eine vergleichsweise hohe Elastizität aufweisenden Treib­ladungspulver.The use of tubular compression molded propellant charge as an ignition transfer charge and as a support tube for the ignition transfer charge preferably opens up the possibility of a comparatively high-energy ignition transfer charge with a heat quantity of 3 kJ / g to 4.5 kJ / g for ignition when the propellant charge modules are automatically supplied to the cargo space of a large-caliber barrel weapon to use the propellant charge located in the propellant charge module and to use a support tube made of extruded propellant charge powder to increase the energy balance. Advantageously, the composition of the high-energy ignition transfer charge of nitrocellulose with 20% to 50% nitroglycerin provides a favorable prerequisite on the one hand for a high burning rate and on the other hand for a technically simple, precise and stable arrangement on the inside of a tube-like carrier made of and in compressed form a propellant powder with a comparatively high elasticity.

Der Träger besteht dabei nicht aus spröden Übertragungs­ladungen, beispielsweise in Form von gepreßten Anzünd­treibladungskörnern wie NSP (Nitrozellulose-Schwarzpulver), das beispielsweise bei schlagartiger mechanischer Bela­stung während des Handlings unter Umständen bruchanfällig reagieren kann, sondern in vorteilhafter Weise aus einem ein- oder mehrbasigem Treibladungspulver ohne Lösungsmit­tel, das in gepreßter Form insbesondere auch schlagartigen Belastungen Stand hält. Eine besonders gleichmäßige Durch­zündung ist dann gewährleistet, wenn als Trägermaterial das gleiche Material verwendet wird, wie es bei der an­zuzündenden Treibladung selbst verwandt wird.The carrier does not consist of brittle transfer charges, for example in the form of compressed igniter propellant grains such as NSP (nitrocellulose black powder), which can react to breakage, for example in the event of sudden mechanical stress during handling, but advantageously from a single- or multi-base propellant powder without Solvent that can withstand even sudden loads when pressed. A particularly uniform ignition is ensured if the same material is used as the carrier material as it is used for the propellant charge itself.

Durch die Anzündübertragungsladung aus hochenergetischem Treibladungspulver lassen sich stranggepreßte Rohre und Zylinder mit hoher Präzision herstellen und durch ein Klebemittel mit der Innenwand des Trägerrohres verbin­den.The ignition transfer charge from high-energy propellant powder enables extruded tubes and cylinders to be manufactured with great precision and by Connect the adhesive to the inner wall of the carrier tube.

Desweiteren ist durch das Strangpreßverfahren die Her­stellung eines aus unterschiedlichen Treibladungspulvern bestehenden mehrschichtigen Rohres möglich, wobei die von der Treibladungspulverträgerschicht umhüllte hoch­energetische Treibladungspulveranzündübertragungsladung wenigstens einen freien Anzündkanal bildet. Der Preßvor­gang eines derartigen mehrschichtigen Rohres gestattet desweiteren zur Erhöhung der Anzündempfindlichkeit und somit zu einer besseren Anzündübertragung die gleichzei­tige Anordnung oberflächenvergrößernder Längsrillen in einem Arbeitsgang, wobei in einfacher Weise auch Querril­len zusätzlich eingewalzt werden können. Dadurch wird ein Einsatz spezieller Anzündmittel entbehrlich.Furthermore, the extrusion process enables the production of a multilayer tube consisting of different propellant powders, the high-energy propellant powder ignition charge encased by the propellant powder carrier layer forming at least one free ignition channel. The pressing process of such a multilayer pipe furthermore permits the simultaneous arrangement of surface-enlarging longitudinal grooves in one operation in order to increase the sensitivity to ignition and thus for better ignition transmission, wherein transverse grooves can also be rolled in in a simple manner. As a result, the use of special igniters is not necessary.

Der Einsatz des vergleichsweise stoßunempfindlichen Trä­gers ermöglicht die Anwendung weiterer Herstellverfahren zur Bildung einer Anzündübertragungsladung, beispielswei­se durch Einkleben einer vergleichsweise dünnwandigen rohrartigen Folie auf die Innenwand des Stützrohres oder durch Aufspritzen eines aus der Anzündübertragungsladung bestehenden Belages auf die Stützrohrinnenwand.The use of the comparatively shock-insensitive carrier enables the use of further manufacturing methods for the formation of an ignition transfer charge, for example by gluing a comparatively thin-walled tubular film onto the inner wall of the support tube or by spraying a coating consisting of the ignition transfer charge onto the support tube inner wall.

In allen Fällen kann die gemeinsame Wanddicke einer aus der Anzündübertragungsladung und dem Stützrohr be­stehenden Schicht bzw. eines gebildeten Preßlings durch das Herstellverfahren in weiter vorteilhafter Weise vari­iert werden. Die gemeinsame Wanddicke liegt in Abhängig­kei von dem Durchmesser und der Länge des Anzündkanales zwischen 1 mm und 10 mm, vorzugsweise zwischen 1 mm und 7 mm, und gewährleistet beispielsweise bei einem Einsatz der Anzündübertragungsladung in einem Treibladungsmodul eine hohe Stabilität, wodurch das Treibladungsmodul sicher von einem automatischen Lader dem Ladungsraum einer beispielsweise großkalibrigen Rohrwaffe zugeführt werden kann.In all cases, the common wall thickness of a layer consisting of the ignition transfer charge and the support tube or of a compact formed can be varied in a further advantageous manner by the manufacturing process. The common wall thickness, depending on the diameter and the length of the ignition channel, is between 1 mm and 10 mm, preferably between 1 mm and 7 mm, and ensures high stability, for example, when the ignition transfer charge is used in a propellant charge module, so that the propellant charge module is safely separated from one automatic loader can be fed to the cargo space of, for example, a large-caliber barrel weapon.

Die Fig. 1 verdeutlicht die Anordnung eines in nicht dargestellten Rohrwaffen, vorzugsweise in Geschützen, einsetzbaren Treibladungsmoduls 14, welches einen aus der DE-34 32 291 A 1 bekannten und spiegel- sowie ro­tationssymmetrisch aufgebauten Behälter 15 zur Aufnahme von an sich bekanntem Treibladungspulver 16 enthält und für eine zentrale Anzündung einen auf der Symmetrieachse 18 befindlichen freien Anzündkanal 17 umfaßt, der zur Anzündübertragung eine den Anzündkanal 17 begren­zende Anzündübertragungsladung 1 aufweist.1 illustrates the arrangement of a propellant charge module 14 which can be used in guns, not shown, preferably in guns and which contains a container 15 known from DE-34 32 291 A 1 and constructed in a mirror-symmetrical and rotationally symmetrical manner for receiving propellant powder 16 known per se and for a central ignition comprises a free ignition channel 17 located on the axis of symmetry 18, which for ignition transmission has an ignition transmission charge 1 delimiting the ignition channel 17.

Die Anzündübertragungsladung 1 besteht aus einem hoch­energetischen Treibladungspulver mit einer Wärmemenge von 3 kJ/g bis 4,5 kJ/g. Vorzugsweise besteht dieses hochenergetische Treibladungspuzlver aus einer Mischung von Nitrozellulose mit 20 % bis 50% Nitroglyzerin. Die Anzündübertragungsladung kann in unterschiedlicher Art und Weise innerhalb eines die Anzündübertragungsla­dung 1 umhüllenden Stützrohres 2 angeordnet sein. Das Stützrohr 2 besteht aus einem üblicherweise gebräuchli­chen ein- oder mehrbasigem Treibladungspulver 16 ohne Lösungsmittel, wobei die Rohrform durch ein Preß­verfahren, vorzugsweise durch Strangpressen, erzeugt wird.The ignition transfer charge 1 consists of a high-energy propellant powder with a heat quantity of 3 kJ / g to 4.5 kJ / g. This high-energy propellant charge preferably consists of a mixture of nitrocellulose with 20% to 50% nitroglycerin. The ignition transmission charge can be arranged in different ways within a support tube 2 enveloping the ignition transmission charge 1. The support tube 2 consists of a commonly used single- or multi-base propellant powder 16 without solvent, the tube shape being produced by a pressing process, preferably by extrusion.

In der Fig. 1 ist die Anzündübertragungsladung ebenfalls wie das Stützrohr 2 als vorgeformtes Rohr 4 ausgebil­det und ist mit der Innenwand 3 (Fig. 2) des Stützroh­res 2 durch ein Klebemittel 9 (Fig. 3), das vorzugs­weise punktweise oder linienförmig gleichmäßig in Um­fangsrichtung (Fig.3) und in Längsrichtung (Fig.5) auf­getragen ist, verbunden. Die Anzündübertragungsladung 1 bzw. das Stützrohr 2 enthält innenseitig an den beiden Enden Zentrierungen 19 zur Befestigung an dem Behälter 15. Die Anzündübertragungsladung kann desweiteren innen­seitig mit oberflächenvergrößernden und eine Aufrauhtiefe von 0,5 mm bis 3 mm aufweisenden Längsrillen 11 (Fig.2) und/oder mit ähnlichen Querrillen 12 (Fig.5) versehen sein, wobei die Längsrillen bereits gleichzeitig mit dem Preßverfahren ausgebildet und die Querrillen anschließend eingewalzt werden können.In Fig. 1 the ignition transfer charge is also formed like the support tube 2 as a preformed tube 4 and is with the inner wall 3 (Fig. 2) of the support tube 2 by an adhesive 9 (Fig. 3), which is preferably punctiform or linear even in the circumferential direction (Fig.3) and in the longitudinal direction (Fig.5) is connected. The ignition transfer charge 1 or the support tube 2 contains on the inside at both ends centering 19 for attachment to the container 15. The ignition transfer charge can furthermore inside with surface-enlarging and a roughening depth of 0.5 mm to 3 mm having longitudinal grooves 11 (Fig. 2) and / or be provided with similar transverse grooves 12 (FIG. 5), the longitudinal grooves already being formed simultaneously with the pressing process and the transverse grooves subsequently being able to be rolled in.

Die Anzündübertragungsladung 1 kann auch, wie es die Fig. 2 zeigt, mit einer die Anzündübertragungsladung 1 rohrartig umhüllenden Treibladungspulverschicht 5 ein gemeinsam stranggepreßtes mehrschichtiges Rohr 6 bilden.The ignition transfer charge 1 can also, as shown in FIG. 2, with a propellant charge powder layer 5 that envelops the ignition transfer charge 1 in a tubular manner, a jointly extruded multilayer tube 6 form.

In der Fig. 3 ist in einer weiteren Ausführungsvariante die Anzündübertragungsladung 1 als ein mit der Innenwand 3 des Stützrohres 2 beispielsweise über Klebemittel 9 verbundener Zylinder 10 ausgebildet, der wenigstens zwei, bevorzugt 4, gleiche und symmetrisch angeordnete sowie parallel zur Längsachse 18 verlaufende freie Anzündkanä­le 13 enthält.3, in a further embodiment variant, the ignition transfer charge 1 is designed as a cylinder 10 connected to the inner wall 3 of the support tube 2, for example via adhesive 9, which has at least two, preferably 4, identical and symmetrically arranged free ignition channels that run parallel to the longitudinal axis 18 13 contains.

Die Fig. 4 verdeutlicht desweiteren einen auf der Innenwand 3 des stranggepreßten Stützrohres 2 rohrartig aus der Anzündübertragungsladung 1 bestehenden aufge­spritzten Belag 7. Durch eine durch das Aufspritzverfah­ren bedingte Oberflächenrauhigkeit kann deshalb die An­ordnung zusätzlicher Maßnahmen zur Vergrößerung der Anzündoberfläche entbehrlich sein.FIG. 4 furthermore illustrates a coating 7 that is sprayed on the inner wall 3 of the extruded support tube 2 from the ignition transfer charge 1 in a tube-like manner. Because of the surface roughness caused by the spraying process, the arrangement of additional measures for enlarging the ignition surface may therefore be unnecessary.

Die Anzündübertragungsladung 1 kann gemäß Fig. 5 auch als Folie 8, insbesondere auch als eine mit Rillen 11, 12 gekerbte Folie 8, ausgebildet sein und auf der Innensei­te des stranggepreßten Stützrohres 2 rohrartig aufge­klebt sein.5 can also be designed as a film 8, in particular also as a film 8 notched with grooves 11, 12, and can be glued to the inside of the extruded support tube 2 in the manner of a tube.

Bedingt durch den Durchmesser und die Länge des An­zündkanales 13 lassen sich in unterschiedlichen Herstell­verfahren Schichten in einer gemeinsamen durch die An­zündübertragungsladung 1 und das Stützrohr 2 gebildeten Wandstärke S formstabil zwischen 1 mm und 10 mm, vorzugs­weise zwischen 1 mm und 7 mm, herstellen.Due to the diameter and the length of the ignition channel 13, layers with a common wall thickness S formed by the ignition transfer charge 1 and the support tube 2 can be produced in a dimensionally stable manner between 1 mm and 10 mm, preferably between 1 mm and 7 mm, in different manufacturing processes.
