Abstract
The research proposes a flagmill,which is a new wind power generator utilizing the flutter of a flexible sheet.The sheet is simply supported at the leading edge by a supporting pole which rotates around its axis.The flutter of sheet causes the rotational oscillation of the supporting pole around its axis.The rotational oscillation of the generator axis connected to the supporting pole induces the electric power.In the present research,the experiment and the two-dimensional stability analysis were performed.The flutter behaviors and power generation characteristic were investigated experimentally and analytically.Flutter flow speeds,modes,frequencies were investigated by varying uniform flow speeds,sheet lengths,and compared with the analytical results.The results mdicated that the angular amplitudes are the most important for the power generation and accordingly the first mode can generate the larger power than the second one.
