THE DESIGN OF WOOD EPOXY WIND TURBINE BLADES

摘要

This paper reviews the design of wood epoxy wind turbine blades for horizontal axis wind turbines. Attention is drawn to establishing the most relevant kind of input wind data, the necessary materials data, and the tolerances on blade geometry that must be achieved to ensure good mass and aerodynamic balance of the rotor, thereby minimising yaw system fatigue. Fatigue design is crucial for system survival, and the development of new methods for the fatigue design of stall regulated and tip controlled rotors is outlined.
