A barrel assembly (10) for munitions and firearms, said barrel assembly including a barrel (12) having a muzzle with a plurality of tubular rounds (11) stacked axially within the barrel together with discrete selectively ignitable propellant charges (15). The rounds (11) suitably include tubular bodies (13a, 13b, 13c, 13d) and closure means (14a, 14b, 14c, 14d) interposed between the tubular rounds for effecting both an operative barrel closure between the tubular rounds (11) and operative sealing engagement with the barrel (12). The propellant charges (15) are contained within each round (11) and selectively ignitable (15a) for propelling an adjacent leading round (13a) and associated closure means (14a) through the muzzle of the barrel.
L'invention porte sur un ensemble canon (10) d'arme à feu/munitions consistant en un tube (12) s'ouvrant sur une bouche, contenant plusieurs coups (11) empilés axialement, et autant de charges propulsives (15) pouvant être mises à feu séparément. Les coups (11) ont des corps (13a, 13b, 13c, 13d) sensiblement cylindriques. Des bourres (14a, 14b, 14c, 14d) intercalées entre les coups servent à la fois d'obturateurs efficaces entre les coups (11) et de joints étanches avec le tube. Chaque coup (11) contient une charge propulsive à mise à feu sélective (15a) qui propulse le coup voisin précédent (13a) et la bourre correspondante par la bouche du canon.
