Abstract: The use of eigenvectors to assign eigenvalues to modes for the p-k formulation of the flutter equation is described. The procedure has the potential to overcome some of the problems of the determinant iteration procedure to solve the flutter equation. Advantages of the proposed procedure include the possibility of using a general eigenvalue routine capable of solving repeated eigenvalues, effective distinguishing of eigenvalues, initial frequency values requirement used only for the first calculation of reduced frequency at each speed, and reduced computation time.
