Projectile (10) is for use with barrel assemblies of the type having a plurality of axially disposed projectiles within a bore and wherein discrete propellant charges are provided for propelling respective projectiles sequentially from the bore. Projectile (10) comprises expandable sleeve (11) encircling at least part of core (12). Sleeve (11) and core (12) have wedging surfaces (14) operable to deform trailing part (21) of sleeve (11) into sealing engagement with the bore in response to pressures exerted on projectile (10). When projectiles (10) are axially disposed in the bore, rear face (24) of the leading projectile cooperates with leading face (20) of the trailing projectile to define a discrete space about spine (23) for receipt of the propellant charge. Sleeve (11) is retained about core (12) during travel to the target.
L'invention concerne un projectile (10) pour barillets du type comportant plusieurs projectiles disposés axialement à l'intérieur d'un canon et dans lesquels des charges propulsives séparées permettent de propulser en séquence les projectiles respectifs hors du canon. Le projectile (10) comprend un manchon expansible (11) entourant au moins une partie du noyau (12). Le manchon (11) et le noyau (12) présentent des surfaces de calage (14) permettant de déformer la partie arrière (21) du manchon (11) avec formation d'un joint avec le canon en réponse aux pressions exercées sur le projectile (10). Lorsque les projectiles (10) sont disposés axialement dans le canon, la face arrière (24) du projectile de tête coopère avec la face avant (20) du projectile suivant de façon à définir un espacé séparé autour de la pointe (23) destiné à recevoir la charge propulsive. Le manchon (11) est retenu autour du noyau (12) lors du trajet vers la cible.
