초록

The invention concerns a fin-stabilized projectile for employment from a rifled barrel and is particularly suitable for automatic cannons having calibers from 12.7 to 70 millimeters. The full rate of spin commensurate with the rifling twist of a specific barrel and the muzzle velocity is imparted to the projectile during launch using a rotating band which is fixed and an integral component of the discarding sabot. Subsequent to exit from the muzzle of the gun the rate of spin of the projectile is decelerated rapidly by aerodynamic damping to avoid potent...

청구항

A fin-stabilized discarding sabot subcaliber projectile fired from a rifled cannon at full spin commensurate with the rifling twist and muzzle velocity comprising a subcaliber long rod penetrator and a fixed fin assembly attached to the rear of the penetrator, the projectile having a predetermined nutation frequency, the fin assembly having an aerodynamic design providing the penetrator with a minimum longitudinal stability margin of 1.2 subcaliber projectile diameters, aerodynamic damping in roll to result in a spin half life of not more than 0.10 secon...
