Definitions

  • the present invention relates to a novel method for providing K-E ammunition, such as sub-calibre arro - type projectiles provided with sabots, with plastics driving bands of a type which is known per se, which plastics driving bands, upon firing from specifically designed barrels, seal against the inner side of the barrel and skid into a specifically matched groove in the sabot of the projectile.
  • the invention also includes the plastics driving band which is configured in accordance therewith.
  • plastics driving bands at all as barrel seals in respect of different types of ammuni- tion dates back a long way, although it was primarily full-calibre projectiles with plastics driving bands which were originally in mind.
  • a variant of such a plastics driving band for full-calibre projectiles is described, for example, in Swedish patent 7506856-9.
  • skidding plastics driving bands are generally used in respect of K-E ammunition as a powder- gas seal between the sabot and the inner side of the barrel.
  • these plastics driving bands have been fitted in place by making use of the natural elasticity of the driving band material and by forcing them over the rear guide bead of the sabot and down into the specifi ⁇ cally designed grooves in the sabot.
  • the driving band is opened by virtue of a suitably configured parting cut running transversely across its casing surface, so that it can easily be forced apart and drawn over the guide bead in question, whilst, at the same time, the latter can be fully dimensioned.
  • the driving band is able to recover its original shape. It is also conceivable, following assem ⁇ bly, to glue or weld the driving band together along the parting cut, but, rather surprisingly, this has been shown to be unnecessary.
  • the driving band is therefore divided, including during firing, there has been shown to be no risk whatsoever of the driving band collapsing.
  • the parting cut may be variously configured, but obliquely placed cuts would probably be preferable, although purely axial, straight cuts might also be con ⁇
  • Pig. 1 shows a side projection of an arrow-type projec ⁇ tile prepared for fitting of the driving band, and a driving band which is ready to be fitted
  • Fig. 2 shows an oblique projection of a driving band according to the invention
  • Fig. 3 shows the finished projectile.
  • the complete projectile 1 shown in the figures comprises the arrow-type projectile 2 itself, which has a front tip 3 and a rear fin tail unit 4. It is sur ⁇ rounded, in turn, by a sabot 5, which is divided along the cut 6.
  • the various parts of the sabot 5, which are preferably not less than 3 in number, are held together by a front breaking band 7.
  • a driving band groove 8 In the rear part of the sabot there is a driving band groove 8, which is surrounded on each side by a front guide bead 9 and a rear guide bead 10.
  • the driving band 11 is prepared for fitting by means of its casing wall being cut through along at least one cut 13, which is preferably inclined relative to its width and which therefore opens the driving band in such a way that, in the manner indicated in Fig. 1, it can be forced apart and drawn over the rear guide bead 10 and down into the specifically designed groove 8, after which the two sectional surfaces 13a and 13b respectively, by virtue of the elasticity of the material, are brought back into contact with each other, guided as they are by the edges of the driving band groove 8.
  • a check is made to ensure that it is able to rotate freely within its groove, after which the projec ⁇ tile is ready for delivery.

Abstract

Procédé permettant d'équiper des munitions à énergie cinétique telles que des projectiles sous-calibrés de type flèche (2), de ceintures de forcement glissantes en matière plastique (11) jouant le rôle de joints d'étanchéité dans le tube-canon. A cet effet, les ceintures de forcement sont équipées, avant leur mise en place, d'au moins une fente (13) traversant la surface de leur enveloppe et facilitant l'emboîtement de la ceinture de forcement dans une gorge (8) de conception particulière. L'invention concerne également la ceinture de forcement finie.
