INVENTOR: RUDOLF ROSSMANN INVENTION: PROJECTILE CONTAINING A FLARE COMPOSITION SLEEVE AND METHOD FOR SECURING THE FLARE COMPOSITION SLEEVE IN A BORE AT THE TAIL OF A PROJECTILE BODY ABSTRACT OF THE DISCLOSURE For the attachment of a flare composition sleeve in a bore at the tail of a projectile body it was heretofore necessary to maintain very exact fabrication tolerances in ordec to provide a reliable sealing action against the propellant gases. To avoid this drawback the invention contemplates, in a ficst method step, pressing the flare composition sleeve, with the aid of a pressing plug or pin, into the bore at the tail or rear portion of the projectile body and, during a second method step, a ring-shaped edge of the flare composition sleeve is enlarged by means of an elastically deformable, such as a plastic or rubber plug until the ring-shaped edge bears against a ring-shaped groove of the bore wall of the projectile body. The flare composition s1eeve possesses at the aforementioned end confronting the projectile body a smaller or at most the same wall thickness as at the remaining region.
