Abstract
From a plurality of sabots, a sabot is provided for shrouding a sub-caliber projectile to form a launch package in a gun bore for acceleration by an actuator behind the projectile. The sabot includes a forecastle, an aft bulkhead and a waist. The forecastle separates the projectile from the gun bore. The aft bulkhead abuts against the actuator. The waist connects the forecastle and the bulkhead by a radial spar that supports inner and outer flanges. The inner flange mechanically engages the projectile, and in preferred embodiments is concave. The gun bore is optimized as a pair of electromagnetic rails.
Claims6
A sabot of a plurality of angularly distributed segments for shrouding a sub-caliber projectile to form a launch package in a gun bore for acceleration by an actuator behind said projectile, said projectile having a nose tip, each segment of said sabot comprising:
- a forecastle that separates the nose tip of the projectile from the gun bore at a radially bow protrusion;
- an aft bulkhead that abuts against the actuator;
- and
- a waist that longitudinally connects said forecastle and said bulkhead by a radial spar that extends between inner and outer flanges to form an I-beam cross-section, with said inner flange mechanically engaging the projectile and said outer flange radially extending within said bow protrusion, and
- wherein said outer flange is concave in relation to said spar.
