多重シートに励起される空力連成フラッタ （シート枚数の影響）

抄録

This paper describes characteristics of coupled flutter generated on multiple sheets in uniform flow. A fluid-structure interaction model considering aerodynamic interaction among the sheets is developed. Moreover, wind-tunnel experiments are performed. Various flutter modes are generated according to the sheet number due to aerodynamic interaction among the sheets. In addition, it is found that anti-phase mode becomes unstable at the lowest velocity regardless of sheet number.
