A family of airfoils, the S411, S412, and S413, intended for rotorcraft applications has been designed and analyzed theoretically. The two primary objectives of high maximum lift,relatively insensitive to roughness, and low profile drag have been achieved. The constraint on the pitching moment of the primary airfoil, the S411, has been exceeded; those of the outboard and tip airfoils, the S412 and S413, respectively, have been satisfied. The constraints on the airfoil thicknesses have been satisfied. The primary airfoil incorporates a 5-percent-chord tab.
