MUNITION COMPORTANT UNE CHARGE PROPULSIVE ET UN PROJECTILE STABILISE PAR AILETTES

MUNITION COMPORTANT UNE CHARGE PROPULSIVE ET UN PROJECTILE STABILISE PAR AILETTES.LA SURFACE DE PROPULSION EST CONSTITUEE DES SEGMENTS 21 DESTINES A SE DISLOQUER. LA SURFACE SOUMISE A LA PRESSION DES GAZ A UN PROFIL CONTINU EN PARTANT DU REBORD EXTERNE 23 ET SE RAPPROCHANT DE LA ZONE PERIPHERIQUE 18 DU PROJECTILE 10.APPLICATIONS: AUX PROJECTILES PERFORANTS. A munitions round for a subcaliber projectile to be fired from a barrel-type weapon has a casing, of a uniform outer cross section substantially over its entire length, receiving the projectile which is at least partially surrounded by the gas-generating propellant charge. A drive body is mounted at the forward end of the projectile and has a rearward pressure-receiving surface which droops inwardly toward the projectile from an outer edge of the body which is engaged by the casing. The body is formed from a plurality of segments which form-fittingly hug the projectile and have confronting angularly spaced separating surfaces bridged by a sealing member. The forward end of the body, formed by the segments, is concave forwardly and has a leading edge which is disposed outwardly and axially ahead of the rearward inner edge of this surface which forms a pocket engaging the air upon propulsion of the projectile from the barrel to effect separation of the segments and dislodgment of the body.
