Abstract:

A family of airfoils, the S407, S409, and S410, intended for a high-altitude, tandem-rotor helicopter 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 constraints on the pitching moments and airfoil thickness have been satisfied.
