Abstract
Wind turbines, which are installed under the natural wind conditions, suffer complicated fluctuation of aerodynamic loads on the rotor blades due to the turbulent wind. The turbulence of the wind should be taken into account in design process of the wind turbines. In the present paper a numerical method of calculating the effects of turbulence on the aerodynamic loads is described, and the calculated results are shown. For the input to the aerodynamic load analysis, the turbulent wind field is simulated by using veers' model. This model is based on a Fourier synthesis method and capable of considering spatial cross-correlations between any two points in the rotor plane, where the turbulent wind is generated. For the calculation of aerodynamic loads on the rotor blades an inviscid aerodynamic model based on the asymptotic acceleration potential method is adopted.
