Abstract
(EN)
This invention provides a projectile assembly (10) having a body part (14) including a trailing portion (19) which reduces in diameter rearwardly and supports a sealing band (16) having a substantially cylindrical outer face for engagement with the bore (21) of the barrel (11). The body part (14) may move rearwardly through the sealing band (16) to expand it outwardly into sealing engagement with the bore (21). Upon firing the body part (14) moves forwardly relative to the sealing band (16) to free it from the bore (21).
(FR)
L'invention concerne un ensemble à projectiles (10) comprenant une partie corps (14) dotée d'une partie de queue (19) qui présente un diamètre diminuant vers l'arrière et entourée d'une bande d'isolation (16) ayant une face extérieure sensiblement cylindrique destinée à venir en contact avec l'âme du canon (11). La partie corps (14) peut être déplacée vers l'arrière à travers la bande d'isolation (16) de sorte que cette dernière se dilate vers l'extérieur et qu'elle vienne en contact hermétique avec l'âme (21). Lors de la mise de feu, la partie corps (14) se déplace vers l'avant par rapport à la bande d'isolation (16) de sorte que cette dernière s'éloigne de l'âme (21).
