Hi eveyone,

I am a PhD student and I am using XFOIL in order to get the pressure distribution along a blade. I want to know if it is completely necessary to normalize an airfoil before using XFOIL or not. What I want to mean is, do I need to first translate, rotate and normalized to [0,1] my airfoil? I have doubts because without normalising, I am able to get good results but I do not know if I am doing things correctly.

Thank you very much <span class="info"></span>
