Abstract
本文主要以實驗探討微飛行體（如昆蟲或微飛行器）在飛行時，不同轉翅時機與所產生升力之關係。由實驗的結果發現：不同的翼面轉動時機影響其升力甚鉅；當轉速加快時，平均升力值一般均會有所提昇，不同的轉翅時機有不同的增加倍率；另外，上、下拍的速率比不一樣時，平均升力值也會隨之改變。總體而言之：太晚的A轉動（連接下拍轉成上拍之轉動）是造成拍翅飛行物體升力降低最致命的禁忌，其次是太晚的B 轉動（連接上拍轉成下拍之轉動）。
Influence of rotation timing for flapping wing flight on the flying lift has been experimentally investigated in this study. The results reveal that rotation timing has significant influence on the flying lift. The averaged flying lift increases for high rotation wing velocity. Based on the comparisons of flying lift, too late A-rotation (connecting from wing downward motion to upward one) is the most serious taboo for the motion design of the micro air vehicles with flapping wings. Too late B-rotation (connection from upward motion to downward one) should also be avoided.
