Title (EN) A CARTRIDGE ASSEMBLY
(FR) ENSEMBLE DE CARTOUCHE
Abstract:
(EN) A cartridge assembly is provided, in one embodiment, comprising a combustible casing (101) with an open forward end (103) and an open breach end (104), enclosed at the breach end by a thin metal stub casing (106), a projectile assembly (120) mounted in the forward end (103), an igniter assembly (130), a resilient obturator (150) pop riveted to the casing, an annular sabot (122), and a plurality of flexible combustible priming tubes (190) immersed in a propellant charge (180) and extending the length of the casing. In another embodiment, the combustible casing comprises two separate casings (201, 301) joined together with fasteners (402), each casing having a set of flexible combustible priming tubes (291, 391), an interface portion (401) defined between the two where respective ends (292, 393) of combustible priming tubes abut. In both embodiments, the priming tubes combust rapidly producing complete spontaneous ignition of the propellant charge and resultant stable projectile flight.
(FR) Dans un mode de réalisation, l'ensemble de cartouche comprend une douille combustible (101) possédant une extrémité avant ouverte (103) et une extrémité de brèche ouverte (104), celle-ci étant enfermée par un étui terminal métallique mince (106), un ensemble projectile (120) monté dans l'extrémité avant (103), un ensemble allumeur (130), un obturateur élastique (150) riveté à la douille, un sabot annulaire (122), et une pluralité de tubes d'amorçage combustibles et souples (190) immergés dans un propergol solide (180) et s'étendant sur toute la longueur de la douille. Dans un autre mode de réalisation, la douille combustible comprend deux douilles séparées (201, 301) reliées par des attaches (402), chaque douille possédant un ensemble de tubes d'amorçage combustibles et souples (291, 391), une partie d'interface (401) définie par les deux douilles là où les extrémités respectives (292, 393) des tubes d'amorçage combustibles se touchent. Dans les deux modes de réalisation, les tubes d'amorçage brûlent rapidement et mènent à un allumage spontané et total du propergol solide et donc à un vol stable du projectile.
