System and method for designing airfoils

摘要

The present invention relates to a system and a method for designing an airfoil by means of an analytical airfoil profile, said method comprising the step of applying a conformal mapping to a near circle in a near circle plane, wherein the near circle is at least partly expressed by means of an analytical function, said conformal mapping transforming the near circle in the near circle plane to the airfoil profile in an airfoil plane. The invention further relates to design optimization of airfoils, in particular airfoils of rotor blades for wind turbines. The invention further relates to specific airfoil profiles.
