摘要


無人飛行載具提供人類許多便利,如空中攝影、設備酬載、國土地形勘查、空汙調查、追颱探察等等,早已成為民間航空和軍事航空的重要潮流之一,目前UAV發展方向之一是改善推進系統(提升其續航力)達成長滯空低重量為重要目標。另橫流風扇因其性能會隨軸向長度及轉速的增加而上升、使用簡易結構裝置即形成穩定流場及送風方向可隨不同設計風道而改變等特性,用作飛行器的推進系統可提升推進效應及短程起降之能力,可改善前述無人飛行載具續航力的問題。 本研究目的旨要以實作方式研製一台應用橫流風扇為推進系統之創新型無線遙控之無人飛行載具,並以實驗方式來探討其推進效果、排氣流場分佈特性及飛行可行性。並與傳統軸流式無人飛行載具比較起飛之推進性能與耗電量。 研究結果顯示:(1)本研究完成一部以橫流扇為推進系統的無人遙控飛機,並驗證其可飛行;(2)其最大推力可達到0.65公斤及10公尺短場起降之能力;(3)與傳統重量、機身大小相同軸流式無人遙控飛行載具比較,在使用相同鋰聚電池之下,起飛所需動力為388.5瓦,節省耗能約25%。

Unmanned aerial vehicle (UAV) offers many conveniences for mankind, such as aerial photography, equipment payload, land terrain exploration, air pollution surveys, Typhoon exploratory chase, etc., has become one of the important trends of civil and military aviation. Currently, one of the UAV development directions is to improve propulsion system (i.e. to enhance the ability of flying endurance) and to reach the target of long endurance flight and low weight. In addition, due to the characteristics that the aerodynamic performances increase with increasing rotating speed and axial length, the stable flow field can be formed by using simple structure means and air blowing direction may be changed with different designs of the duct, the cross-flow fan can be used as aircraft propulsion systems, which may promote the propulsion effect and the short takeoffs/landings ability, and improve the aforementioned UAV flying endurance problems. The purpose of this study is to develop an innovative wireless remote unmanned aerial vehicle (UAV) with cross-flow fan (CFF) thrust system by implementation. Then, an experimental investigation is applied to explore the performance of thrust, the characteristic of the exhaust flow field distribution, and the feasibility of flight. Additionally, compared with traditional axial-flow UAV, the thrust performance and power consumption are discussed. The results show that (1) an wireless remote control UAV using the cross-flow fan as thrust system is completed and verified that it can fly; (2) the maximum thrust created by this CFF-UAV reach 0.65kgf and the shortest distance for taking off/landing is 10m; (3) comparing with traditional axial-flow UAV with similar weigh and body size, the present CCF-UAV only consumed 388.5W power during taking off and saved energy consumption of about 25%.
