LOW SPIN SABOT

摘要

A discardable sabot includes first and second supports (50, 52) dimensioned to cooperate with an inner surface of a weapon barrel. At least one of the supports is a sealing support (52), configured to provide a substantially gas-tight seal with the barrel (12) and effective to allow the sabot and the projectile (28) to be propelled forward through the barrel by expansion of propellant gas behind the sealing support. The sabot includes surfaces (100) for permitting a flow of a portion of the gas through the sabot while redirecting such portion at least partially transverse to the longitudinal barrel 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 (14) and muzzle (16).
