碩士 === 國立成功大學 === 航空太空工程學系碩博士班 === 93 === 　　Human beings flying with the help of aircraft of various kinds have been able to fly for about one century. Although the flapping wings of animals served as an inspiration to pioneers of human flight, we don’t really understand how they work. In this thesis, we employ the concept of four- bar linkage to design a flapping mechanism which simulates the flapping motion of a bird. The upstroke angle and downward angle can be varied in the design. This experiment focuses on aerodynamic characters including the lift and thrust. The effects of frequency, wind velocity and angle of attack on the left and thrust were investigated. This research provides some preliminary understanding to the flapping wing, which could give some information for the following research.
