Some New Airfoils for Rotorcraft

Abstract

Ten, natural-laminar-flow airfoils, the S406, S407, S409, S410, S411, S412, S413, S414, S415,and S418, intended for rotorcraft applications, have been designed and analyzed theoretically. Five of the airfoils, the S406, S407, S411, S414, and S415, have been experimentally verified. The measurements have been compared with predictions from two, widely used airfoil codes as well as from two, computational fluid dynamics codes.
