Description

Bei der insensitiven Artilleriemunition besteht zwischen dem insensitiven Sprengstoff (IHE) und der Geschosswand kein direkter Kontakt, um das Entstehen von thermischen Spannungen bedingt durch die unterschiedlichen Wärmeausdehnungen von IHE und Geschosshülle zu unterbinden. Daher wird zwischen beiden ein Liner, in der Regel ein Plastiksack, in die Geschosshülle eingebracht. Anschließend wird der IHE eingegossen und ausgehärtet.In the insensitive artillery ammunition there is no direct contact between the insensitive explosive (IHE) and the projectile wall in order to prevent the development of thermal stresses due to the different thermal expansions of the IHE and projectile shell. Therefore, a liner, usually a plastic bag, is inserted into the projectile casing between the two. Subsequently, the IHE is poured in and cured.

Ein Verfahren zur Herstellung eines großkalibrigen Sprenggeschosses und Sprenggeschoss, hergestellt nach diesem Verfahren wird mit der EP 1 338 860 B1 offenbart. Hier wird ein Liner aus einer Kunststoffhülle aus einem elastischen Material vorgeschlagen, damit das sich bei Temperaturschwankungen ändernde Volumen der Sprengladung durch die elastische Kunststoffhülle aufgenommen wird. Das Einbringen des Liners erfolgt durch ein Mundloch, welches normalerweise zur Aufnahme des Kopfzünders dient, in zusammengefalteter oder zusammengepresster Form. Im entfalteten Zustand entspricht diese sackförmig ausgebildete Kunststoffhülle den Abmessungen des Innenraumes des Sprenggeschosses.A method for producing a large-caliber explosive projectile and explosive projectile produced by this method is with the EP 1 338 860 B1 disclosed. Here, a liner made of a plastic sheath made of an elastic material is proposed, so that the temperature fluctuations fluctuating volume of the explosive charge is absorbed by the elastic plastic sheath. The introduction of the liner is made through a mouth hole, which normally serves to receive the head fuse, in a folded or compressed form. In the unfolded state, this bag-shaped plastic casing corresponds to the dimensions of the interior of the explosive projectile.

In einigen Fällen ist der Liner nicht so steif, die eigenen auftretenden Wärmeausdehnungen entsprechend der Ausdehnung der Sprengladung kompensieren zu können. Aufgrund der großen Wärmeausdehnung zieht dich die Sprengladung bei Abkühlung / Erwärmung um mehrere mm zusammen bzw. dehnt sich aus. Der Liner zieht sich mit der Sprengladung zusammen, dehnt sich aber nicht im gleichen Maß mit aus. Hierdurch kommt es zu einer Verschiebung des Liners auf der Sprengladung. Der Liner schiebt sich über viele Temperaturwechsel relativ zur Ladung nach hinten, so dass die Sprengladung teilweise freiliegen kann.In some cases, the liner is not so stiff as to be able to compensate its own thermal expansions according to the extent of the explosive charge. Due to the large thermal expansion, the explosive charge pulls you together when cooling / warming by several mm or expands. The liner contracts with the explosive charge, but does not expand to the same extent. This results in a shift of the liner on the explosive charge. The liner slides over many temperature changes relative to the charge backwards, so that the explosive charge can be partially exposed.

Die EP 1 376 047 A2 betrifft ein Geschoss mit einer splitterbildenden äußeren Hülle und ein Verfahren zu seiner Herstellung. Dabei befindet sich eine innenseitig an die äußere Hülle anschließende Kunststofffolie, in der eine Sprengladung angeordnet ist. Die Kunststofffolie selbst ist mit in einem strukturierten Bereich mit dachförmigen Einbuchtungen und mindestens einem sich diesem anschließenden an der Innenwand der äußeren Hülle formschlüssig anliegenden glatten Bereich versehen. Im strukturierten Bereich besteht die Kunststofffolie aus einem verformungssteifen Material, welches ein Eindrücken der dachförmigen Einbuchtungen verhindert, während im glatten Bereich sich die Kunststofffolie elastisch und formschlüssig gegen die Innenwand der äußeren Hülle drückt. Durch diese beiden Bereiche unterschiedlicher Festigkeitseigenschaften wird eine Rissbildung des kunststoffgebundenen Sprengstoffes während der Beschleunigungsphase des Geschosses verhindert. Die Sprengladung befindet sich hierbei in der Kunststofffolie, nicht zentral im Geschoss. Die Einbuchtungen haben hierbei die Aufgabe, ein Reißen der den Sprengstoff umhüllenden Kunststofffolie bei Beschleunigung des Geschosses zu verhindern.The EP 1 376 047 A2 relates to a projectile with a fragment-forming outer shell and a method for its production. In this case, there is an adjoining the outer shell plastic film, in which an explosive charge is arranged. The plastic film itself is provided with in a structured area with roof-shaped indentations and at least one adjoining this on the inner wall of the outer shell form-fitting smooth area. In the structured area, the plastic film consists of a deformation-resistant material, which prevents impressions of the roof-shaped indentations, while in the smooth area, the plastic film elastic and positive presses against the inner wall of the outer shell. These two areas of different strength properties prevent cracking of the plastic-bonded explosive during the acceleration phase of the projectile. The explosive charge is here in the plastic film, not centrally in the floor. The indentations here have the task of preventing cracking of the plastic film enveloping the explosive during acceleration of the projectile.

Hier stellt sich die Erfindung die Aufgabe, das sich Verschieben eines Liners auf der Sprengladung zu verhindern.Here, the invention has the object to prevent the displacement of a liner on the explosive charge.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.The problem is solved by the features of claim 1. Advantageous embodiments are listed in the subclaims.

Der Erfindung liegt die Idee zugrunde, eine Art Wulst oder Nocken in den Liner einzubinden bzw. einzuarbeiten, die einen Formschluss zur Ladungsvorderkante oder in der Ladung realisieren.The invention is based on the idea to incorporate or incorporate a kind of bead or cams in the liner, which realize a positive connection to the front cargo edge or in the charge.

Zwar ist aus der DE 1 812 462 A1 ein Geschoss mit Splittermantel bekannt, worin sich eine von einer Folie umgebene Sprengladung befindet und diese Folie, die aus Stahl, Kupfer oder Kunststoff bestehen kann, eine Anzahl längliche, sich in Längsrichtung des Geschosses erstreckende, in Reihe angeordnete Einbuchtungen aufweist, doch dienen diese zur Bildung kleiner Hohlladungen, die gegen einen zylindrischen Splittermantel gerichtet sind, welcher die Folie mit der Sprengladung umgibt. Bei der Detonation des Sprengstoffkörpers werden durch die kleinen Hohlladungen Kerben in den Splittermantel geschnitten und der Mantel entlang dieser Kerben in Splitter zerlegt. Die Größe der Splitter entspricht den Abständen zwischen den Einbuchtungen einer Reihe und den Abständen zwischen den Reihen. Eine Nutzung zur Fixierung der Folie gegenüber der Sprengladung ist nicht angedacht.Although is out of the DE 1 812 462 A1 a projectile with fragmentation shell, in which there is an explosive charge surrounded by a foil and this foil, which can be made of steel, copper or plastic, has a number of elongated, extending in the longitudinal direction of the projectile, arranged in series indentations, but these serve for Formation of small shaped charges, which are directed against a cylindrical fragment jacket, which surrounds the film with the explosive charge. During the detonation of the explosive body, notches are cut into the fragment shell by the small shaped charges and the shell is split into splinters along these notches. The size of the splitter corresponds to the distances between the indentations of a row and the distances between the rows. A use for fixing the film against the explosive charge is not considered.

Der Wulst kann dabei umlaufend ausgeführt sein. Wird der Liner in einer gefalteten Form in die Geschosshülle eingebracht, bietet sich eine Segmentierung der umlaufenden Wulst an. Die dabei entstehenden Nocken weisen gleichfalls eine sehr hohe Formsteifigkeit auf, die Zwischenräume ermöglichen ein einfaches Falten des Liners.The bead can be performed circumferentially. If the liner is introduced into the projectile casing in a folded form, a segmentation of the circumferential bead offers itself. The resulting cams also have a very high stiffness, the spaces allow easy folding of the liner.

Um die Formsteifigkeit der Nocken zu erhöhen empfiehlt es sich, die Steifigkeit der Nocken gezielt beispielsweise dadurch einzustellen, dass die Wandstärke / Materialdicke im Bereich der Nocken verstärkt wird. Eine Variation ist auch mittels der Breite und der Tiefe der Wulst möglich.In order to increase the stiffness of the cams, it is advisable to adjust the stiffness of the cams, for example, by increasing the wall thickness / material thickness in the region of the cams. A variation is also possible by means of the width and the depth of the bead.

Als vorteilhaft hat sich auch erwiesen, mehrere Reihen von Wülste oder Nocken in den Liner einzubringen.It has also proven advantageous to introduce several rows of beads or cams in the liner.

Die Nocken oder Wülste können durch eine einfache Modifikation des Linerwerkzeuges in den Liner bei seiner Herstellung eingearbeitet werden.The cams or beads may be incorporated into the liner during its manufacture by a simple modification of the liner tool.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt:

Fig. 1
eine Teilansicht eines Geschosse mit einem eine Wulst aufweisenden Liners,
Fig. a
eine leicht vergrößerte Darstellung der Wulst aus Fig. 1,
Fig. 2
eine Teilansicht des Geschosses mit einem wenigstens zwei Wülste aufweisenden Liners.
Reference to an embodiment with drawing, the invention will be explained in more detail. It shows:
Fig. 1
a partial view of a projectile with a beaded liner,
Fig. A
a slightly enlarged view of the bead Fig. 1 .
Fig. 2
a partial view of the projectile with a least two beads having liner.

Fig. 1 zeigt in einem Ausschnitt ein Geschoss 1, aufweisend eine Geschosshülle 2, einen Liner 3, der sich zwischen der Geschosshülle und eine Sprengladung 4 befindet. Um ein Rutschen des Liners 3 auf der Sprengladung 4 zu verhindern, ist der Liner 3 an einer zur Sprengstoffoberfläche definierten Stelle L1 mit einer nach innen geformten Wulst / Nocken 5 ausgeführt (Fig. 1 a). Die Wulst 5 ist so steif ausgeführt, dass der Liner 3 je nach Füllhöhe der Sprengladung 4 sofort oder nach wenigen Temperaturzyklen formschlüssig an der Vorderkante der Sprengladung 4 liegt. Fig. 1 shows in a section of a projectile 1, comprising a projectile casing 2, a liner 3, which is located between the projectile casing and an explosive charge 4. In order to prevent slippage of the liner 3 on the explosive charge 4, the liner 3 is designed at a location L1 defined for the explosive surface with an inwardly formed bead / cam 5 ( Fig. 1 a) , The bead 5 is designed so stiff that the liner 3 is depending on the filling level of the explosive charge 4 immediately or after a few temperature cycles form-fitting manner at the front edge of the explosive charge 4.

Fig. 2 zeigt das Geschoss 1 mit mehr als einer eingeformten Wulst bzw. Nocken 5 (Fig. 2a). Die weitere Wulst 6 ist hierbei bei einer zur Sprengstoffoberfläche definierten Länge L2 in den Liner 3 eingebracht und ermöglicht, dass der Liner 3 sich bereits formschlüssig beim Gießen mit der Sprengladung 4 verhaken kann und somit von Anfang an fixiert wird. Fig. 2 shows the projectile 1 with more than one molded bead or cam 5 Fig. 2a ). The further bead 6 is in this case introduced into the liner 3 at a length L2 defined for the surface of the explosive and allows the liner 3 to already interlock positively with the explosive charge 4 during casting and thus be fixed from the beginning.

Prinzipiell ist hier davon auszugehen, dass auch hier, wie bekannt, die insensitive Sprengladung 4 in das Artillerie- Sprenggeschossen 1 eingegossen wird. Um ein Anhaften der Sprengladung 4 an der Innenwand der Geschosshülle 2 zu vermeiden, wird der Liner 3, in Form einer elastischen gummiartigen Kunststoffhülle, eingesetzt. Das Einsetzen in die Geschosshülle 2 erfolgt durch ein Mundloch 7. Der insensitive Sprengstoff 4 besteht aus Sprengstoff und einem Kunststoffbindersystem mit weiteren Zusätzen. Dieser wird in den Liner 3 hineingegossen und härtet darin aus. Der ausgehärtete, geformte Sprengstoff bildet somit die kunststoffgebundene Sprengladung 4. Die Sprengladung 4 weist gegenüber der Geschosshülle 2 aus Stahl einen um Faktor 8 bis 12 größeren Temperaturausdehnungskoeffizienten auf.In principle, it can be assumed here that, as is known, the insensitive explosive charge 4 is poured into the artillery explosive projectile 1. In order to avoid adhesion of the explosive charge 4 to the inner wall of the projectile casing 2, the liner 3, in the form of an elastic rubber-like plastic casing, is used. The insertion into the projectile casing 2 takes place through a mouth hole 7. The insensitive explosive 4 consists of explosives and a plastic binder system with other additives. This is poured into the liner 3 and cures in it. The hardened, shaped explosive thus forms the plastic-bound explosive charge 4. The explosive charge 4 has over the projectile casing 2 made of steel by a factor of 8 to 12 greater temperature expansion coefficient.
