The description of experimental installation, parameters of experiment and results of research of non-stationary aerodynamic coefficients of a wing with generators of vortexes in the conditions of non-stationary flow is resulted. It is shown, that effects connected with longitudinal vortical structure which generate generators of vortexes are considerably shown at low Strouhal numbers. At increase in frequency of oscillations intensity of cross-section vortexes which are formed owing to circulation change round a wing at periodic change of an angle of attack increases and the vortical structure formed by generators of vortexes makes considerably smaller impact on the general flow round investigated model, on the foreground there are effects connected with non-stationary flow about the wing.
