CA 2525724

An existing projectile (21) is modified by adding a tail piece (22) to enable axial stacking of multiple projectiles (20) in a common barrel. Propellant for each modified projectile (20) is contained in respective chambers located external to the barrel and connected to the bore of the barrel through associated ports. Tail piece (22) aligns with a respective port and provides a space between consecutive projectiles (20) into which the propellant gas expands after ignition. Separate claims are directed to tail assembly (22), modified projectile (20), the barrel assembly having a plurality of projectiles (20) stacked in end-to-end relation, and to an external initiation system for the barrel assembly (see Figures 4, 7).

L'invention concerne une modification d'un projectile (21) existant consistant à ajouter une queue (22) au projectile de manière à permettre l'empilement axial de projectiles (20) multiples dans un même tube. L'agent propulsif destiné à chaque projectile (20) modifié est contenu dans des chambres correspondantes placées à l'extérieur du tube et raccordées au conduit du tube par des passages correspondants. Cette queue (22) de projectile vient s'aligner avec un passage correspondant et ménage un espace entre deux projectiles (20) consécutifs, dans lequel le gaz propulsif se détend après sa mise à feu. Des revendications distinctes concernent un ensemble queue (22) de projectile, un projectile modifié (20), un ensemble tube contenant une pluralité de projectiles (20) empilés bout-à-bout, et un système de mise à feu externe pour cet ensemble tube (voir figures 4, 7).
