Abstract
This paper is concerned with the basic characteristic properties of three airfoils that are used on wind turbine rotors. The three airfoils are NACA 63-415, NREL S827, and Risø-FFA-W3-241. The information about the airfoils came from wind tunnel test results, research papers, and papers from large organizations whose primary purpose is given to wind energy research. This research paper is a summary of the information found. Results about the NACA 63-415 include that has a high lift to drag ratio, double stall, has sensitivity to leading edge contamination, and responds well to vortex generators. Results for the NREL S827 is that is an airfoil specifically deigned to for wind turbines, less sensitivity to leading edge contamination when compared to the NACA 63 series, and is designed for extra large wind turbines. Results for the Risø-FFA-W3-241 is that it is an airfoil that is designed for the mid-span sections, is 25%-30% thick airfoil, and has high lift to drag ratio is high, relative insensitivity to roughness.
