摘要:
L'invention concerne une munition, en particulier du type télescopé, comprenant un étui en matière plastique constitué d'une enveloppe cylindrique (2) et de deux bouchons respectivement avant (4a) et arrière (4b) situés aux deux extrémités de l'enveloppe, un projectile et un chargement propulsif logés à l'intérieur de l'étui, et un dispositif d'allumage du chargement propulsif, l'invention est caractérisé en ce que un au moins des bouchons (4a,4b) forme une seule pièce venue de moulage avec une partie cylindrique (3a,3b) de l'enveloppe (2) et des moyens de dilatation axiale intégrés sont situés au voisinage de la zone de transition entre la partie cylindrique (3a,3b) de l'enveloppe et le bouchon associé (4a,4b). L'invention s'applique notamment aux munitions de petit et moyen calibre.
摘要:
A high strength polymer-based cartridge comprising a first end (210), a neck (206) disposed at the first end, a shoulder (204) disposed below the neck forming a bottleneck cartridge, a second end (212) opposite the first end, an insert (400) engaged to the second end, a propellant chamber (340) formed between the shoulder and the insert and having a volume, an extension extending from the neck opposite the shoulder and a cap (244) formed on the extension, partially sealing the propellant chamber.
摘要:
The invention relates to a training projectile (1) for short-range use, in particular less than 100 meters, comprising a front region (2), which extends along a central axis (M) and which comprises a projectile tip (3), and comprising a tail region (4), which adjoins the front region (2) in the direction of the central axis (M) and which comprises a projectile end (5). The tail region (4) is designed for receiving the projectile (1) in a cartridge case (6). The projectile (1) comprises a projectile core (7) made of metal and a jacket (8) which surrounds the projectile core (7), determines the outer shape of the projectile (1), and is made of plastics.
摘要:
A high strength polymer-based cartridge casing includes an upper component of polymer having a first end with a mouth, at least a wall between the first end and a second end of the upper component opposite the first end, a sleeve extending longitudinally and radially about the wall, and at least one of an overlap portion and an underskirt portion extending from the wall near the second end. The lower component is molded from a polymer and includes at least one of a tapered portion and an outer tapered portion that engages at least one of the overlap portion and the underskirt portions, respectively, to join the upper and the lower components. Further, the sleeve reduces a volume of a propellant chamber formed by the wall. The reduced volume of the propellant chamber permits only enough propellant to propel a bullet engaged in the cartridge casing at subsonic speeds.
