Abstract

Stiffeners between sabot petals resist bending of a kinetic energy projece, and thereby reduce aiming dispersion. The stiffeners compensate for material removed during the separation of an annular sabot into individual sabot petals, thereby eliminating the need for post-assembly machining to restore a circular perimeter. The stiffeners may extend radially from the surface of the kinetic energy projectile to the gun bore, for direct force carry-through, to reduce flexure and whip. In one embodiment, a thick portion on each stiffener fits into a notch in the abutting sabot petals to strengthen the sabot in a manner similar to an "I" beam.
