Kinetic energy ring projectile

Abstract

A rotatable airfoil non-lethal sting projectile comprising a hollow closed circular ring wing surrounding a central open area. The projectile consists of an aerodynamic lifting body of a thick ring wing geometry which uses spin imparted to it from a launching means for its gyroscopic stability. The combination of aerodynamic stability characteristics and high spin rate (i.e. above 2,000 rpm) results in a flat trajectory and extended range capability. The projectile is intended as a riot control weapon. Impact is non-lethal, but may be painful. The subsonic launch velocity, the non-metallic light weight structure, the soft resilience, and relatively large size of the projectile avoids serious bodily harm due to impact with a person even at point-blank range.
