Abstract
A segmented sabot utilizes a double ramp configuration and a centrally poioned obturating band in alignment with the center of gravity of an in-bore projectile to improve the uniformity of the shear traction forces at the interface between the sabot segments and a subcaliber projectile, to reduce propellant gas blow-by and to enhance projectile in-bore and trajectory stability. The increased uniformity of shear traction forces between sabot and projectile interfaces and propellant gas self-sealing design permits a reduction in sabot weight of sufficient magnitude to increase the velocity of the projectile at the muzzle exit.
