Abstract : The bending response of flexible rotating blades in an airflow is investigated when the input velocities are random functions of time. The spectral density and the mean square of the transverse displacement of the blade is computed, based on the spectral density of the input function. Results for both hinged and hingeless cases of root-end fixity are obtained and compared. (Author)
