Velocity-component aerodynamic-strip theory is used with quasi-steady and unsteady Theodorsen-function representations; exact solutions of differential equation are obtained, thereby eliminating problems of modal convergence; effects of structural damping and below-flutter response are also examined; below certain critical values of mass-density ratio, flutter does not occur; at low values of mass-density ratio increasing sweep-back of given wing lowers flutter speed significantly until critical angle is reached, beyond which flutter speed rises sharply to infinity.
