Payload delivering ring airfoil projectile

A ring airfoil projectile comprising:

• a ring airfoil comprising a nose section and a tail section, said nose and tail sections being selectively connectable to and disconnectable from one another, said nose section defining a nose of the ring airfoil and the tail section defining a tail of the ring airfoil, the ring airfoil having a passage therethrough, said passage having a central longitudinal axis, said nose section defining a first portion of said passage and said tail section defining a second portion of said passage, said first portion of said passage and second portion of said passage collectively forming said passage through said airfoil when said nose and tail sections are connected, said nose section having a rear face and said tail section having a front face, said rear face of said nose section and said front face of said tail section meeting in a plane extending substantially perpendicular to said central longitudinal axis through of said passage when said tail section is connected to said nose section, said nose section having an outer surface and a plurality of payload accepting cavities inset into said outer surface, said ring airfoil further comprising a payload associated with said payload accepting cavities, said nose section constructed of at least one material having a first density and said tail section constructed of at least one material having a second density, the first and second densities of said materials selected so a center of gravity of said ring airfoil projectile dependent upon a mass of said nose section, a mass of said tail section and a mas of said payload, is substantially coincident with a center of pressure thereof.
