Abstract

Die Erfindung betrifft ein Geschoß (1) mit einer splitterbildenden äußeren Hülle (2) und einer innenseitig sich an die äußere Hülle (2) anschließenden Kunststoff-Folie, in welcher eine Sprengladung angeordnet ist, wobei die Kunststoff-Folie (3) einen mit dachförmigen Einbuchtungen (4) versehenen strukturierten Bereich (5) und mindestens einen seitlichen, sich an den strukturierten Bereich (5) anschließenden und an der Innenwand (6) der äußeren Hülle (2) formschlüssig anliegenden glatten Bereich (7, 8) aufweist. Die Erfindung bezieht sich ferner auf Verfahren zur Herstellung eines derartigen Geschosses.The invention relates to a projectile (1) with a splinter-forming outer shell (2) and a plastic film adjoining the inside of the outer casing (2), in which an explosive charge is arranged, the plastic film (3) having a roof-shaped Indentations (4) provided structured area (5) and at least one lateral, adjoining the structured area (5) and on the inner wall (6) of the outer Envelope (2) has a form-fitting, smooth region (7, 8). The invention also relates to methods of manufacturing such a projectile.

Um zu erreichen, daß es bei Verwendung von kunststoffgebundenem Sprengstoff zu keiner Rißbildung des Sprengstoffes während der Beschleunigungsphase des Geschosses (1) kommt, schlägt die Erfindung vor, als Kunststoff-Folie (3) eine Folie zu verwenden, welche mindestens aus zwei Bereichen (5, 7, 8) unterschiedlicher Festigkeitseigenschaften besteht. In dem strukturierten Bereich (5) besteht die Kunststoff-Folie (3) aus einem verformungssteifen Material, welches ein Eindrücken der dachförmigen Einbuchtungen (4) während der Beschleunigungsphase des Geschosses (1) verhindert. In dem glatten Bereich (7, 8) besteht die Kunststoff-Folie (3) hingegen aus einem elastischen Kunststoffmaterial, so daß die Folie in diesem Bereich elastisch und formschlüssig gegen die Innenwand (6) der äußeren Hülle (2) gedrückt wird.

Figure 00000001
In order to ensure that there is no cracking of the explosive during the acceleration phase of the projectile (1) when using plastic-bound explosives, the invention proposes to use a film as plastic film (3) which consists of at least two areas (5 , 7, 8) there are different strength properties. In the structured area (5), the plastic film (3) consists of a deformation-resistant material, which prevents the roof-shaped indentations (4) from being pressed in during the acceleration phase of the projectile (1). In the smooth area (7, 8), on the other hand, the plastic film (3) consists of an elastic plastic material, so that the film in this area is pressed elastically and positively against the inner wall (6) of the outer casing (2).
