Abstract
A wind turbine system is presented. The wind turbine system includes a blade comprising an airfoil and a sensing device disposed on a surface of the airfoil, wherein the sensing device generates signals that are representative of pressure deflection on the surface of the airfoil. The wind turbine system further comprises a processing subsystem that receives location details of the sensing device and a transfer function corresponding to the airfoil, determines a location of a stagnation point on the surface of the airfoil based upon the signals and the location details, and determine an angle of attack (AOA) on the surface of the airfoil based upon the location of the stagnation point and the transfer function.
