Abstract

Wind energy is seen as a viable alternative energy option for future energy demand. The blades of wind turbines are
generally regarded as the most critical component of the wind turbine system. Ultimately, the blades act as the prime
mover of the whole system which interacts with the wind flow during the production of energy. During wind turbine
operation the wind loading cause the deflection of the wind turbine blade which can be significant and affect the turbine efficiency. Such a deflection in wind blade not only will result in lower performance in electrical power generation but also increase of material degradation due high fatigue life and can significantly shorten the longevity for the wind turbine material. In harnessing stiffness of the blade will contribute massive weight factor and consequently excessive bending moment. To overcome this excessive deflection due to wind loading on the blade, it is feasible to use shape memory alloy (SMA) wires which has ability take the blade back to its optimal operational shape. This paper details analytical and experimental work being carried out to minimize blade flapping deflection using SMA.
