Abstract

L'invention concerne un système d'arme (1) pourvu d'un canon (2) et d'un projectile (3) pouvant être chargé séparément d'une charge propulsive dans le canon (2) et comprenant un culot (22), le canon (2) présentant du côté arrière une chambre de chargement à laquelle se raccorde du côté avant, vu dans le sens de tir, une partie de trajet de projectile (6) par l'intermédiaire d'un cône de passage (5). Pour obtenir que dans un tel système d'arme (1), le projectile (3) puisse de nouveau être déchargé sans gros efforts, l'invention propose que, quand il est chargé, le projectile (3) soit relié au canon (2) par au moins un élément de retenue (9) disposé sur le projectile (3). Cet élément de retenue est monté de manière radialement mobile par rapport au sens de tir et peut, dans la position chargée du projectile (3), s'engager dans au moins une rainure (8) circulaire située dans le canon (2) et fixe le projectile dans cette position. Lors d'un changement de munition, la liaison entre projectile (3) et canon (2) peut être rompue simplement du fait que selon l'invention, un élément axialement déplaçable (12) sur le culot (22) agit par l'intermédiaire d'un contour de commande (16) sur l'élément de retenue (9) radialement déplaçable de telle sorte que par un déplacement axial de l'élément déplaçable (12), la fixation par l'élément de retenue (9) est éliminée et le projectile (3) peut de nouveau être déchargé.
