Investigation of Faceted Wing Sections for Low Reynolds Number Applications 2013-01-2097

This paper documents the numerical and experimental investigation of a new type of wing section being developed at West Virginia University that shows good potential for use in wings in low Reynolds number flows. These wing sections have been designed with a minimum number of flat sides, or facets, which are arranged in such a way as to promote flow over the surface similar to traditional smooth airfoil shapes, but without the complexity of the typically highly contoured airfoil form. 2D numerical techniques have been employed to determine appropriate geometric limitations of the wing section facets, and finite span wings comprised of these faceted wing sections have been tested in wind tunnels in wing-only and wing-plus-body configurations to determine their basic aerodynamic performance. The latest results of these efforts, as well as some speculation as to the mechanisms at work are presented.
