Title: Performance of a steel spar wind turbine blade on the MOD-0 100 kW experimental wind turbine

Abstract

The performance and loading of a large wind turbine rotor, 38.4 m in diameter and composed of two-cost steel spar blades has been examined. Two blades were fabricated at Lewis Research Center and successfully operated on the Mod-0 wind turbine at Plum Brook. The blades were operated on a tower on which the natural bending frequency has been altered by placing the tower on a leaf-spring apparatus. It was found that neither blade performance nor loading were affected significantly by this tower softening technique. Rotor performance exceeded prediction while blade loads were found to be in reasonable agreement with those predicted. Seventy-five hours of operation over a five month period resulted in no deterioration in the blade.
