  現代飛行載具之應用當中,無人旋翼機之重要性與需求與日俱增。以及此一類型載具設計資料庫亦略有不足,故探討並設計一初步之概念原型。有鑒於傳統直昇機外型之先天不穩定性對於自主飛行之特性有所影響,本研究採取機體內藏風扇,與推力、昇力分離之概念,以茲增進旋翼機之性能,且減低可操縱之自由度以茲改進。此外,搭配輕量化聚苯乙烯泡沫塑料(Styrofoam)與聚氯乙烯(PVC)為機體,結合電動馬達之應用,以求簡化機身整體結構複雜度,達到精簡構造之目標。本研究詳列基礎設計方向、概念設計之結果、各作用力分析、原型機與各部元件設計構思,以探討此型無人旋翼機設計之可行性。
  It is in concern of the increasing importance and demands on the hovering unmanned rotary crafts, and the lack of prototypes in the design data base so that this study was delivered. In views of the instability of the conventional helicopter configuration will cause some troubles for autonomous rotary crafts, this study would start from the basic principal concept how a helicopter hovers, and with the still same force demand, using another way to deliver the required forces is the goal which should as well be capable of improving the drawbacks of the conventional helicopter like hazardous exposure of the blades, and heavy transmission mechanism. The final prototype combines the idea of the body imbued ducted fan, pendulum phenomenon, electrical driving force, reduction of degrees of freedom in main rotor system, and the replacement forward thrust. This study should state the test body design idea and the manufacturing process for the components, and with both force chart calculation and flight test to testify the practicability of the prototype.
