N2 - A 10% backward sweep is added to the NREL wind turbine blade and its aerodynamic performance is studied using a hybrid Navier-Stokes/Vortex-Panel solver. A modified twist distribution for the swept blade obtained with an optimization vortex code is tested and a higher power gain is achieved in the low wind speed case of compared to the NREL Phase VI rotor. However the backward sweep increased the bending moment. For more relevant comparison with the aerodynamic performance of the straight blade, adjustment of the blade setting angle is done to achieve the same bending moment. It is observed that the backward sweep will improve the stability of the blade for gust control while keeping other aerodynamic performances at or above that of the NREL rotor.
