Performance and Structural Design Aspects of a One-Bladed Electric-Power-Generating Windmill

Design approaches to electric-power-generating windmills that may achieve economically attractive cost of energy are discussed. Innovative approaches to the design of the three highest cost components; rotor, gearbox, and tower are presented. Advantages of the one-bladed rotor are shown. The importance of rotor hub articulation is discussed. Sizing of the windmill so that there can be an adequate market to justify production is also considered. The need for standardization in assumptions made in the accounting aspects of cost analyses, and the requirements for wind prospecting to determine with assurance the geographic areas that have sufficient wind are shown.
