With the aid of a perturbation technique, a formula is derived for the purpose of determining the exact value of the critical flutter load Q sub d of a non-gyroscopic system of two degrees of freedom, subjected to a non-conservative force, in the limit as the value of the internal damping parameter becomes vanishingly small. The principal results of the general theory are applied to obtain an expression for Q sub d for a double pendulum, which has viscoelastic hinges, rotating at constant angular velocity, carrying a tip mass, and subjected to a tangential force at its free end.
