What is it about?
In the present model, the aerodynamic coefficients of airfoils in the entire range of angles of attack are expressed in terms of analytical relations. A modeling test has been made for the thick airfoil DU97-W-300 and the model captures its complex aerodynamic behavior within a relative error of less than 5% in the entire 360 degrees range.

Why is it important?
The knowledge of these values is important for aerodynamic modeling on wind turbines and aircraft in the high range of angles of attack. The design of wind turbines requires rapid and accurate evaluation of aerodynamic loads. The same requirement is encountered for flight simulation of aircraft in post-stall configuration.
