Extract

The basis for the calculation of wing vibration has been laid by the work of Küssner (I). The present paper describes a comparatively simple and yet accurate method of solving the two-dimensional problem in a manner suitable for the aircraft designer. In addition some of the results obtained by the new method are discussed.

Vibrations of the type considered by these authors are mainly governed by breakaway of the flow and only occur at large angles of incidence of the wing. Breakaway phenomena also exert an influence when the amplitude of the wing vibrations has reached large values.Google Scholar
As Studer has treated vibrations of this type very fully, they will not be further considered by us.Google Scholar
