Abstract: Until recently, it has become clear that unsteady mechanism, including high frequency flapping, is necessary for insects to produce enough lift and to keep themselves aloft. Imitating insects, the flapping mechanism is designed, which converts the rotational motion of motor into the two-degree-of- freedom flapping motion of wings. The lift of flapping wings is measured by the force-measuring device. Instantaneous aerodynamic forces are calculated under a set of kinematic parameters. The study can be used as a preparation for the design of micro air robot with flapping wings.
