A cartridge assembly (10) for firearms or weapons, said cartridge assembly including a support body (11) having a central longitudinal channel (16) housing a plurality of projectiles (20, 22, 24) in end-to-end orientation and having a plurality of circumferential chambers (14), wherein each chamber houses (14a, 14b, 14c) at least one propellant charge (12a, 12b, 12c) and is located adjacent to a respective projectile; fluid communication means (18) included in the support body for communicating the products of a gaseous expansion of said propellant from a respective chamber (14) into said central longitudinal channel (16); whereby, upon initiation of a selected propellant charge (12a, 12b, 12c), the communicated products of gaseous expansion from a circumferential chamber force or eject a respective projectile (20, 22, 24) from the cartridge assembly (10). The propellant charges may comprise a volume of propellant material encased in a bag with an igniter.

L'invention concerne un système de cartouche (10) pour armes à feu ou armes, ledit système de cartouche comprenant un corps support (11) présentant un canal longitudinal central (16) logeant une pluralité de projectiles (20, 22, 24) en orientation bout-à-bout et présentant une pluralité de chambres circonférentielles (14). Chaque chambre loge (14a, 14b, 14c) au moins une charge propulsive (12a, 12b, 12c) et est adjacente au projectile respectif. Un élément de communication fluidique (18) est inclus dans le corps support pour faire passer les produits d'une détente gazeuse dudit propulseur d'une chambre respective (14), à l'intérieur du canal longitudinal central (16). Sur initiation d'une charge propulsive sélectionnée (12a, 12b, 12c), les produits dégagés de la détente gazeuse depuis une chambre circonférentielle poussent ou éjectent un projectile respectif (20, 22, 24) hors du système de cartouche (10). Les charges propulsives peuvent comprendre un volume de matériau propulseur logé dans un sac avec un amorceur.
