Sažetak
This paper deals with the investigation procedure and results of applying an adaptive airfoil for wind turbine blades. A flexible airfoil skin allows deformation in the elastic zone of the adaptive part of the airfoil. This skin is attached on the stiff airfoil core. The deformation of the flexible airfoil shape depends on forces caused by the pressure field of a given wind speed. This results in a change of airfoil aerodynamic characteristics and wind turbine power regulation. Flow and elastic deformation are investigated with CFD/FSI analysis. Simulation of working characteristics of wind turbine with adaptive airfoils results in a positive energy yield when compared to the stiff airfoil shape. Further numerical and experimental investigations are proposed and described.
