The wind system consists of a horizontal-axis, two-bladed, down-wind rotor, which is free in yaw and is supported by a cantilevered free standing tower. Control of blade pitch is provided by a passive system consisting of pendulums which are sensitive to centrifugal forces created by rotor rotation. Rotor speed control in high winds is achieved by blade stall and the system is designed to withstand gusts up to 56 m/s. The design of the electrical system, head assembly, and nacelle and the tower design and erection are described briefly. Also discussed is the system analysis, consisting of predicted power output and annual energy capture, cost of energy, analysis of loads and stresses, availability, and safety. Experimental tests were performed in support of the design in the areas of materials evaluation and component testing. (LEW)
