Flutter is studied using velocity-component aerodynamic-strip theory; direct method is employed which incorporates exact expression of Theodorsen function and, therefore, yields exact eigenvalues of non-self-adjoint boundary value problem; it is shown that exact analysis predicts finite values for flutter speed at relatively low mass-density ratio; effect of structural damping is examined and it is shown that internal damping forces may have important influence on flutter speed of system.
