I am studying the deflection failure on the wind turbine blades. I have done some analysis using ANSYS and matlab programans in order to calculate the blade deflection. FAST is a powerfull tool used in wind turbine calculation, so I want to compare the results with FAST results.
But I have a problem with airfoil data. I have all airfoil data correct except one. I need S818_30 airfoil data and I have S818_27 one. I know that the drag and lift coefficients are not the same. I haven't found it, so I would greatly appreciate if you could provide me or help me.
Thank you very much in advance,
