An elastic retention ring for the combustible casing of a piece of ammunition with respect to a base, the ring including two concentric substantially ring-shaped portions, one internal the other one external. The portions are linked by radial arms, and are continuous or not and have different diameters. The external portion incorporates at least one plane part and the radial arms form an angle with respect to the plane of plane part.

Elastic retention ring for combustible casings

A device including a ring for linking a case and a projectile carrying a sealing band having a rear skirt providing low pressure sealing and a front rib lodged in a first groove in the projectile. The ring has a flared rear part connected with the case and a front part connected with the projectile by attachment means. The front part of the ring is lodged between the rear skirt of the band and the projectile and has a lip co-operating with the first groove or with a second groove in the projectile. A process for mounting the sealing band and ring to link the case and projectile includes sliding the sealing band and ring along the projectile in a single operation.

Device to link a case and a projectile and process to mount a band onto a projectile implementing such a linking device

A saboted projectile for ensuring gas tight sealing of a threaded penetrator with its sabot having a tapping. This sealing device is formed of an elastomer element applied on the rear portion of the sabot and comprises a lip in resilient abutment on the penetrator and is obtained by molding over the sabot having an insert engaged therein.

Sealing device for an arrow projectile

The technical sector of the invention is that of devices for stopping rotation between a rifled bar and a sabot of an arrow-type projectile. The device according to the invention is characterized in that it comprises at least one obstacle (6) disposed in a housing (7) made radially in the sabot (1), immobilized in translation in its housing by a locking means and one end (8) of which comes into contact with the bar (2) at the level of a bearing surface arranged at a distance from the axis (4) of the bar which is at least equal to the maximum diameter of the rifling of the bar. Application to large-caliber arrow-type munitions.

Device for stopping rotation between a bar and a sabot

A subcaliber projectile including a penetrator preferably made of tungsten eavy metal, and having a penetrator tip section and a section following thereafter and extending over the major portion of the penetrator length which is provided with an external thread (helical groove) or circumferential annular grooves to provide a form-locking connection with a discardable propelling cage sabot. To realize improved piercing power for the penetrator, the form-locking region is composed of annular grooves without a pitch, or of a fine metric thread having a thread valley, with a width of approximately one to three times the base width of the groove defining wall or of a thread peak. Preferably a more brittle material is employed in the front penetrator region than in the tail region, and a further indentation structure is incorporated in the first frontal thread turns or grooves of the form-locking region.
