Semi-Empirical Prediction of Airfoil Hysteresis

Semi-Empirical Prediction of Airfoil Hysteresis

A semi-empirical method is presented to estimate the angular excursion and the lift loss associated with static hysteresis on an airfoil. Wind tunnel data of various airfoils is used to define and validate the methodology. The resulting equation provides a relationship between the size of the hyster...
