Design, Build, and Testing of a Swept Back Free-Wing Aircraft

This paper describes the concept of a radio-controlled free-wing aircraft involving a wing sweep to retain sufficient control without sacrificing airfoil aerodynamic characteristics. The topics include the design process, fabrication, and wind tunnel testing. The free-wing concept allows the wings to freely rotate about a spanwise axis, independent of the fuselage. Previous attempts at free-wing design involved full-span control surfaces which...
