Abstract
Obturator ring comprising two or more pieces each being a little larger than semicircle of the projectile obturator ring groove circumference. Each piece at natural position has equal or smaller radius than the radius of the obturator ring groove of a projectile; therefore, each piece expands to be in the projectile groove. Thickness and height of each piece is dependent on projectile's obturator ring groove geometry. The overlap and the radius ensures each piece performs its own grip function independent to the completion of the Segmented Obturator Ring (SOR). SOR seals the expanding propellant gases in the tube optimizing the effectiveness of the propellant while the projectile moves along the gun tube with SOR. After launch, the SOR is totally separated from the projectile minimizing drag effects on and maximizing stability of projectile to enhance dispersion impacts of the warhead.
