S827 and S828 Airfoils; Period of Performance: 1994--1995

National Wind Technology Center

Research output: NREL › Subcontract Report

Abstract

A family of thick, natural-laminar-flow airfoils, the S827 and S828, for 40- to 50-meter, stall -regulated, horizontal-axis wind turbines has been designed and analyzed theoretically. The two primary objectives of restrained 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.
