Abstract : An analytical method for predicting the perturbed aerodynamic reactions of a harmonically oscillating flat plate airfoil with time dependent point of separation is presented. It is shown that this method in conjunction with an empirical knowledge of the time history of the separation point can predict stall flutter. Numerical results are presented and compared with existing theoretical and experimental results. (Author)
