Abstract
A ring airfoil projectile is defined by an annular body which defines a central passage. The body is constructed so that a center of pressure is substantially coincident with a center of gravity thereof. The body is preferably constructed of a nose section and tail section, the nose section of a material having a higher density than the material forming the tail section. The ring airfoil projectile is configured to deliver a payload to a target. Cavities extend inwardly from the outer surface of the airfoil, preferably in the nose section. The cavities accept payload or a strip containing payload. The ring airfoil projectile is configured to travel with minimum path dispersion, and to deliver the payload upon impacting a target.
