Recently, various studies of Micro Air Vehicle (MAV) and Unmanned Air Vehicle (UAV) have been reported from wide range points of view. The aim of this study is to research the aerodynamic improvement of flapping wing in low Reynolds number region to develop applicative these air vehicles. The six kinds of elliptical wings made of stainless steel are used in the flapping wing. The effects of flapping amplitude and wing configuration regarding the aerodynamic characteristics are investigated in detail. The fluid force measurement by six-component load cell and PIV analysis are performed as the experimental method. In the flapping wing experiment, we tried to relate the force measurement and PIV data at the same timing by means of encoder signal from the flapping motion. The relations between the aerodynamic superiority and the vortex behavior around the models are demonstrated.
