Abstract
Abstract A sabot, having four quadrant sections, for use in testing of impact damage of metal fragment-type products. The quadrant sections include molded alignment guides and a depression which forms a central cavity for holding payloads. Recesses are provided in the quarter sections to reduce weight. An external gas plug flare is provided on the external surface of the sabot. The sabot has a conical recess at the forward end with a hole into the interior of the sabot to enhance separation of the quadrant sections after the sabot has left the gun barrel.

Claim 1
Independent Claim
197 words
A sabot for firing projectiles from smooth-bore gun barrels, comprising: four identical quadrant sections with each quadrant section including a depression adapted to form a central cavity together with the other quadrant sections wherein the central cavity is adapted for holding payloads; means on each quadrant section for aligning each quadrant section with adjacent quadrant sections; each of the quadrant sections having a portion of a conical surface, adapted to fit with corresponding conical surfaces of the other quadrant sections to form a conical recess at the forward end of the sabot; said quadrant sections including means for cooperating with the other quadrant sections to form a hole into the interior of the sabot; said quadrant sections including means, on the external surface, for preventing escape of propulsion gas past the sabot during launch; said depression in each quadrant section being shaped to form different size cavities in different portions of the sabot; a plurality of weight reducing depressions in each quadrant section; said aligning means including a plurality of projections and a plurality of grooves wherein the projections and grooves on each quadrant section are adapted to engage corresponding grooves and projections on adjacent quadrant sections.
