Abstract: A projectile arrangement including a subcaliber projectile body and a segmented, discardable propelling cage sabot provided with a common form locking zone for the transmission of the acceleration forces. To reduce the notch effect on the projectile body, and thus the danger of breakage, due to the conventional thread grooves in the form locking zone, particularly in long, slender penetrators made of a breakage susceptible tungsten heavy metal, a novel form locking connection for the inner form locking region between the propelling cage and the projectile body is provided. This novel form locking connection is characterized in that in the region of the form locking zone beneath the exterior gas pressure receiving surface of the sabot, only the exterior surface of the projectile body is provided with preferably annular microgrooves and the surrounding inner surface of the sabot is smooth.

Abstract: A segmented, discardable sabot for a slender sub-caliber kinetic energy projectile. At least two sabot segments are provided having adjacent plane parallel segment separating faces and presenting at least one caliber-sized gas sealing pressure flange member and a non-caliber sized partial region along the longitudinal extent of the sabot. The overall cross section of the sabot, at least in the partial region, has an essentially polygonal cross-sectional shape, and a tangent placed at any point of the periphery of the sabot does not pass through the cross-sectional area of the sabot, thereby providing increased bending stiffness in the non-caliber-sized region of the sabot.
