Abstract:	有別於傳統的拍翼機構為剛性的認定，本研究提議使用可撓式的碳纖維棒與聚對二甲苯薄膜，分別作為掌狀大小微飛行器之機翼骨架與機翼蒙皮。即便拍翼(齒輪連桿)傳動機構只是單自由度的四連桿(機構)設計，但上下拍翼的連動經由可撓性機翼的材質與外型設計，成功耦合到流向的前後振動，故使翼尖組合出三維的八字形拍翼軌跡。該八字形軌跡以高速攝影機成功拍攝驗證，且發生於接近或甚至超過18Hz 的拍翼頻率，本仿生機翼應用於全機重10gw 以下，翼展20cm 以下的拍翼微飛行器，已可持續飛行32 秒以上。飛行測試結果顯示，本仿生八字形拍翼軌跡可經由空氣彈性力學之本質而自動產生，無需藉助複雜精巧的三維機構設計。 Relaxing from the conventional regarding of the "rigid" flapping mechanism, in this work the authors proposed to use the "flexible" carbon-fibers and parylene films as the wing frames for palm-size micro aerial vehicles (MAVs). By combining the coupling streamwise vibration of the wing frame and the driving flapping motion with one degree of freedom only, a figure-eight stroke of wing tips trajectory is verified via a high speed camera with the flapping frequency beyond 18 Hz. The experiment results conclude that this biomimic figure-eight flapping is done by the very nature of the aero-elastic interaction rather than the delicate 3D motion formulated purposely from the mechanism design.
