<p>Recently, many researchers have been regarding as important to realize high flight performance such as an insect's and bird's flights adopting an idea of bio-mimetics for the sake of precise and prompt survey of situation of disaster, development of the Mars airplane. Additionally, various studies of micro air vehicle (MAV) and unmanned air vehicle (UAV) have been reported from wide range points of view. In general, important features of the aerodynamics of biological flapping flyers result from large flapping wing movement and rotation, small size and low flight speed. In this study, the flow around a flapping model at a lower Reynolds number of 2.18×10⁴ is investigated. Various wings made of ABS resin with different taper configurations along span and chord wise directions were manufactured by three-dimensional printer. The fluid force measurement by six-component load cell and PIV analysis are performed as the experimental method. We investigated that the relation between the aerodynamic characteristics and fluid phenomena such as the layout of the leading-edge, trailing-edge and wing-tip vortices through wind tunnel experiments and PIV analysis.</p>
