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.

Abstract: The invention is a multi-shot launcher adapted to launch ring airfoil projectiles. Each ring airfoil projectile is coupled to a sabot, the ring airfoil projectile and sabot mounted to a housing in a cartridge form. The cartridge has a length which is less than its diameter. The launcher includes a receiver defining a cartridge receiving area and a tubular passage through which the ring airfoil is launched from a fired cartridge. The launcher includes a trigger mechanism for firing a cartridge. The launcher includes an ejector for ejecting the housing of a spent cartridge from the receiving area and a loader for loading a new cartridge into the receiving area. The cartridge may be loaded from a magazine connected to the receiver.
