本研究以輕量化之鋁製連桿組搭配塑膠齒輪，組成拍翼式飛行器之傳動機構，並且，利用聚對苯二甲酸乙二醇脂薄膜及聚對二甲苯薄膜做為翼膜，彈性碳纖維棒做為機翼骨架，鋰電池為動力來源，構成全機重量為6公克左右之拍翼式飛行器。 本研究主要針對聚對苯二甲酸乙二醇脂翼膜及聚對二甲苯翼膜，進行拍翼式飛行器的升推力量測及能量消耗的探討，經由風洞實驗，發現本研究拍翼式飛行器之升推力足以供給實際飛行所需。 本研究亦利用高速攝影機拍攝拍翼式飛行器之翼尖軌跡，分析此翼尖軌跡的形狀，分析的結果顯示本研究拍翼式飛行器之翼尖軌跡為一8字型軌跡，此8字型是因為機翼本身具備撓性所形成。 本研究最後將拍翼式飛行器實際飛行於空中，飛行時間已可超過100秒，高度10公尺左右，飛行距離超過60公尺。 This research is about the aerodynamic experiments of the flexible wings on a flapping micro aerial vehicle(MAV). Flapping MAV is a kind of biomimetic mechanism. It gains the lift force and thrust force via the cyclic up and down motions of the wings like birds or insects. Because of the complicated motions, the aerodynamic characteristics of the flapping MAV are unsteady. In this research, first we use aluminum linkages, aluminum motor base, and plastic gears to assemble the gear transmission system of the MAV. Then we use the flexible carbon fiber as the wing spars, and use the PET and the parylene as the wing films. We choose the lithium battery as the power source. Finally, we make up a MAV which is only 6 grams in weight, 20 centimeters in width. After making up the MAV, we use PET films and the parylene films to do some aerodynamic experiments of it. From the experiment results, we know that the aerodynamic forces are sufficient to the MAV. Besides, we also use the high speed CCD to record the wing tip trajectory of the MAV. After analysis, we find that the wing tip trajectory is a figure-of-eight. And this figure-of-eight trajectory is produced by the flexible wing spars. Finally, we have some flying tests. The parameters of the flying MAV are the same to the experimental one. The endurance of the MAV is more than 100 seconds, the range is more than 60 meters, and the height is more than 10 meters.
