Can a wind turbine rotor blade operate within the fatigue limit?
It is possible to produce a wind turbine blade capable of operating within the fatigue limit of its materials. However, such a design would require excessive amounts of structural material resulting in a heavy, large, expensive and inefficient blade. Fatigue loading conditions are therefore unavoidable in efficient rotor blade design.
How can a wind turbine design improve its performance?
More efficient blade designs may produce more energy and redistributing critical loads equally may boost turbine robustness by changing airfoil and blade design. Aerodynamics, aero-acoustics, and structural design can improve wind turbine performance, energy production, asset life, and environmental effects.
