THE aim of this paper is to calculate the natural frequencies and to consider the influence of the damping parameter on a wing's natural flexural and torsional vibration. The author took into account only the elastic hysteresis of the material because the structural damping, depending on the type of the aeroplane, cannot be taken into account in a general consideration.
