Dragonfly wings have excellent aerodynamic performance and damping capacity, which is driving people's attention. The existing researches on it are mainly from the vein structure and focusing on the static performance demonstration of dragonfly wings. Flutter analysis is very important during the process of aircraft design. With the inspiration of internal flow of dragonfly wings, the Coriolis force on the pipe wall while vibrating is discussed. By establishing a two-dimensional wing model, using quasi-steady aerodynamic equation, the aerodynamic force and the Coriolis force generated while fluttering were calculated. Theoretical calculation and numerical method are used to find critical velocity with and without internal flow. Coriolis force is proved effective on reducing two-dimensional wing flutter.
