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 sealing bands for arrow-type munitions. The sealing band (5) according to the invention is arranged in an annular groove (9) of a sabot (2) of an arrow-type projectile, and is characterized in that it comprises a substantially annular rear zone (8) on which, when the band (5) is positioned in the groove, comes into contact a seal (6) joined to the sabot, and in that it comprises means (12, 13, 17) ensuring its mechanical joining, due to similarity of shape, with the material forming the seal (6). Application to the field of large-caliber munitions.

Sealing band for an arrow-type 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.
