Abstract : This report documents the results of a wind tunnel test conducted to determine the aerodynamic characteristics of unbanked wings from low to high angles of attack at subsonic and transonic speeds. Several wing models with differing planform geometry were tested. All wings were full-span with straight taper, zero trailing-edge sweep, constant bevel angle normal to all edges and constant thickness. The aerodynamic data obtained consisted of normal-force, axial-force, pitching-moment, yawing-moment, and semispan root bending-moment coefficients. Longitudinal, spanwise, and vertical aerodynamic centers of pressure were computed from the force and moment data.
