Abstract
This paper describes vibration characteristics of a cantilevered flexible sheet subjected to a periodic gust. In an experiment, active plates are set at the upstream part of a wind-tunnel and generate the periodic gust. Moreover, a theoretical model to calculate a gust response using the Doublet-point method based on the unsteady lifting surface theory is developed. The frequency response of the sheet is examined with changing the frequency of the gust and flow velocity. Finally, the results of simulated transfer functions of the gust induced by active plates to the sheet are presented in comparison to the experimental data derived by the wind-tunnel experiment.
