S825 and S826 Airfoils: 1994--1995

S825 and S826 Airfoils: 1994--1995

National Wind Technology Center

Research output: NREL › Subcontract Report

Abstract

A family of airfoils, the S825 and S826, for 20- to 40-meter, variable-speed and variable-pitch (toward feather), horizontal-axis wind turbines has been designed and analyzed theoretically. The two primary objectives of high maximum lift, insensitive to roughness, and low profile drag have been achieved. The constraints on the pitching moments and the airfoil thicknesses have been satisfied. Theairfoils should exhibit docile stalls.
