Abstract:
(EN) A launch system for ammunition which can be fired by a small, medium or large calibre weapon with a smooth bore or a bore having shallow or deep rifling, particularly a hunting weapon. The system comprises a launching ring (9) placed on the side of the head of the sub-projectile (6) and translationally fixed thereto, a movable launching ring (10) capable of being moved along the sub-projectile by the thrust from the propellant gases, and a sealing device (11) arranged between the ring fixed to the sub-projectile and the movable ring. The system is relevant for subcalibre ammunition of all calibres.
(FR) L'invention concerne un système de lancement pour munition tirable par une arme à âme lisse, faiblement ou fortement rayée de petit, moyen ou gros calibre et en particulier pour arme de chasse. Le système selon l'invention est constitué d'un anneau-lanceur (9) disposé du côté de la tête du sous-projectile (6) et solidaire en translation de ce dernier, un anneau-lanceur mobile (10) susceptible de se déplacer le long du sous-projectile sous l'effet de la poussée des gaz de propulsion, et un dispositif d'étanchéité (11) disposé entre l'anneau solidaire du sous-projectile et l'anneau mobile. Application en domaine des munitions sous calibrées de tous calibres.
