ABSTRACT	To investigate the unsteady flow characteristics of the oscillating 2D wing, we developed an innovative mechanism to drive 2D wing models. The major design concepts of the system are; 1)?uasi-harmonic pitching oscillation up to frequency of 8 Hz via 3 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 2D wing model.
