Abstract
In this chapter, aerodynamics analysis of Vestas V47 wind turbine is implemented by the use of modified blade element momentum (BEM) theory to determine aerodynamics performances such as output power, axial, and tangential forces which can be coupled with structural analysis to predict aeroelastic behavior of wind turbine blade. Unlike most BEM analysis of a wind turbine blade, in this code effect of drag coefficient is considered to have more accuracy results. Also convenient critical axial induction factor in Glauert correction is determined. Another correction which is Prandtl tip loss factor is considered and the effect of these correction factors is obtained. To validate current analysis, the only available data is real field measurement that is done by Vestas Company and power and power coefficient are compared with these data.
