%X In order to investigate the effect of camber wing with wing-blade located beneath the wing surface on the aerodynamic characteristics of flapping-wing micro air vehicle, wind tunnel test of flapping-wing MAV(Micro Air Vehicle) was performed in a special micro air vehicle wind tunnel of NPU(Northwestern Polytechnical University). Wing with wing-blade and wing without wing-blade were employed for wind tunnel tests at different attack angle. Experimental results indicate that the lift coefficient of wing with wing-blade is larger than that of wing without wing-blade. So it is proved that wing-blade can prevent spanwise airflow beneath wing surface and increase wing lift. At small attack angles, wing with wing-blade can increase effectively aerodynamic efficiency of flapping-wing air vehicle and improve flight performance. Results of wind tunnel test provide technology support for application of wing with wing-blade in flapping-wing micro air vehicle.
