Firearm for self-propelling projectiles, self-propelling projectiles and their production.

摘要

The invention relates to a firearm for firing self-propelling projectiles, forming a chamber (1a) containing a powder charge and a primer (4), the case having in its front part a metal mass comprising at least one element (1). This projectile is intended to be fired in weapons comprising a barrel (48) equipped with a chamber (48a) for receiving the projectile, a breech (47) and means for putting the weapon into the firing position and for triggering the shot. At the moment of firing, the part of the projectile containing the primer (4) is in the vicinity of a cavity (471c) which is reserved in the breech (47) and which constitutes a chamber for the expansion of the combustion gases which bring about the propulsion of the projectile. <IMAGE>
