摘要

小型飛行器中是為了能夠在特殊環境從事勘查與聯繫的工作而設計的。小型飛行器以翅膀的運動模式可分類為固定翼、旋轉翼、以及拍撲翼等三大類。本研究目的在於設計與製作具有翅膀且近似鳥類飛行拍打之小型五桿七接頭拍撲飛行機構。
首先探討拍撲機構拓撲構造特性，根據此特性設計與製作一組五桿七接頭拍撲翼飛行機構，推導運動方程式，進而利用左右翅膀桿的角位置方程式設計上拍撲角60°及下拍撲角30°的機構運動尺寸，探討鳥類飛行原理後設計兩組翼展分別為44公分及57公分的翼型，最後以四個不同翼型面與水平面的夾角 ，進行飛行實驗並分析探討其拍撲飛行所產生的浮力與推力現象。實驗結果發現，翼展44cm，在翼型面與水平夾角分別為6°、8°、11°及13°於低頻率拍打時具有使飛行器上升的浮力，翼展57cm於高頻率拍打時，有較佳的拍撲飛行效果，這些具有升力的實驗結果證明本文所提理論與設計是可行的。

The small artificial vehicle was designed for investigating and communicating for some purposes. According the motion of small artificial vehicle’s wings, the vehicles were classified by fixed, rotational, and flapping wings.
By analyzing the topological structure of flapping-wing vehicles, the object of the work is to design a (5,7) linkage as a small flapping-wing vehicle flapping with 60 digs. Upstroke angle and 30 digs. Down stroke angle. In order to analyze the motion characteristics of designed device, we see up experimental device and designed two wing length (44cm and 57cm), and four angles (6°, 8°, 11°, and 13°) between the horizontal and wing planes. The results of the experiment shows a rising force acted on designed device with 44cm wing length under the lower flapping frequency and four angles (6°, 8°, 11°, and 13°), or with 57cm wing length under the higher flapping frequency. The results prove the provided theory of this work is feasible.
