The system investigated is comprised of two elements whose shape and relative position create a beneficial interference effect similar to that achieved by swept wings. The particular geometry of the Compound System is investigated for the capability of recovering loss in LD resulting from the airfoil thickness without the favorable interference effect. Although the basic concept was conceived in terms of triangular shaped airfoils with interfering shock waves which interacted with the airfoil boundary layers, the information derived from this simplified analysis has been utilized to derive airfoil shapes to accomplish the desired effect without undesirable shock boundary layer interactions.
