ABSTRACT:
An armor-piercing projectile comprises a penetrator core carried within a scarding segmented sabot equipped with a plastic spinner band. While the core-sabot assembly is traveling through a rifled gun barrel the plastic band interengages with the rifling to impart spin to the assembly. The rifling severs the spinner band so that when the assembly exits from the barrel the sabot segments are centrifugally slung off of the penetrator core. The core continues its flight toward the target. Improved separation of the segments from the core is achieved because the sabot is constructed so that the severable band is the initial mechanism for retaining the sabot segments on the core during feeding and chambering. The separation lines between the core and sabot segments are pre-established by molding alternate segments in two sequential steps. Also, the segments are mechanically locked together, providing a predictable separation mechanism. The sabot can be fabricated from a wide range of materials and with a minimum of process controls.
