Abstract
A discardable sabot includes a first support and a second support, aft of the first support. The first and second supports are dimensioned to cooperate with an inner surface of a weapon barrel so as to maintain the saboted projectile substantially centered along the longitudinal axis of the barrel during travel of the projectile from the weapon's chamber to the muzzle. At least one of the supports is a sealing support, configured to provide a substantially gas-tight seal with the barrel and effective to allow the sabot and the projectile to be propelled forward through the barrel by expansion of propellant gas behind the sealing support. The sabot includes surfaces for permitting a flow of a portion of the gas through the sabot while redirecting such portion at least partially transverse to the axis so that the flow applies a torque to the projectile about the axis during travel of the sabot and the projectile between the chamber and muzzle.
