Abstract

A national wind energy program has been established to develop the technology required to make wind energy systems cost-competitive with conventional power generation systems and suitable for rapid commercial expansion to produce significant quantities of electrical power. The nominal 1500-kW Mod-2 Wind Turbine Generator being developed will require a rotor diameter of 300 ft (Fig. 1). Because of the considerable extension of technology that is required to produce the 150-ft blades, Structural Composites Industries and Kaman Aerospace Corporation have been awarded a contract by the Department of Energy through NASA-Lewis Research Center to design, fabricate, test, and evaluate a 150-ft composite blade. The primary structural element of the blade is a one-piece 20,000-lb spar fabricated using a new filament winding process, low-cost materials, and minimum labor.
