We measured unsteady aerodynamic forces of a 3D flapping wing in hovering and forward flight using a dynamically scaled mechanical model in a water tunnel, and investigated effects of motion kinematics of a flapping wing on the aerodynamic characteristics. Two simple motion types were used for comparison; trapezoidal and sinusoidal types, whose time histories of angular velocities are represented as trapezoidal and sinusoidal functions, respectively. The results show that the trapezoidal type of flapping motion and the trapezoidal type of feathering motion with the shorter rotational time should be selected in order to obtain higher efficiency in both hovering and forward flight. In order to obtain larger lift, the sinusoidal type of flapping motion and the trapezoidal type of feathering motion should be selected in hovering and slower forward flight; and the sinusoidal type of flapping motion and the sinusoidal type of feathering motion should be selected in faster forward flight.
