The major design concepts of the system are: (1) quasi-harmonic pitching oscillation up to frequency of 8 Hz via three electric motors controlled by the personal computer; and (2) the mean-angles of attack, the amplitude and the frequencies can be changed automatically. The system is used for the flow visualization in a low wind tunnel to view the unsteady flow patterns around an oscillating two-dimensional wing model., 資料番号: AA0001991000, レポート番号: NAL TR-1403}, title = {2次元翼模型加振装置の開発}, year = {2000} }
