A flapping wing machine comprises a fuselage and a flapping wing. The fuselage and the flapping wing (2) are connected. The flapping wing (2) is consisted of a wing rod (21) and a wing membrane (23). The wing membrane (23) is attached on the wing rod (21). The flapping wing machine also includes a vibrator (25) set on the fuselage to swing or vibrate the flapping wing (2). A solution for improving efficiency of a flapping wing aircraft or a high-efficiency flapping wing aircraft is also provided. The aircraft comprises a fuselage, a flapping wing (2), a pressure sensor or an acceleration sensor, a drive mechanism (A) for the flapping wing, a mechanism for adjusting the rigidity of the flapping wing and quality and an electronic control system. Utilizing the dynamic performance of the flapping wing and the fluid, the structure of the flapping wing is simplified, and the flapping wing is uniformly forced; therefore, the mass of the flapping wing is sharply reduced, structural strength thereof is enhanced, and the stress thereon is uniform. Thus, large scale and practical application of the flapping wing can be realized. Utilizing the inherent frequency of the flapping wing and the fluid, the flapping wing can maintain vibration only by supplementing energy equivalent to the energy dissipating for external power to the flapping wing in each period of vibration in the present invention; therefore, the energy consumption of the system can be greatly reduced and the energy efficiency of flapping wing navigation is improved. |
