本研究以實驗法探討Ce-71系列無人機設置高升力裝置的可行性評估，本研究針對幾種可行的設計，製作模型利用吸入式低速風洞進行，並以高壓煙流觀測法，控制主翼攻角與襟翼施打角度、改變控制面面積大小及雷諾數等獲得不同的效應。實驗驗證步驟由風洞實驗對模型機翼的流場觀測實驗開始，完成後將裝置於更改主翼後的老虎II訓練機上進行實際飛行測試，由對地高度及飛行速度的相對變化量進行評估，其結果除可瞭解各個控制因素間的相互關係外，並可提供於Ce-71系列裝置高升力裝置的控制及裝置建議來改善飛行性能。

The feasibility design and evaluation of high-lift devices on Ce-71 series UAV is performed by experimental method. With precision model fabrication, the experiments of high-pressure smoke flow visualization is carried out in a suction type low-speed wind tunnel. The controlling factors on AoA of main wing, the flap deflection, the area of control surface and Reynolds number are changed to obtain visualization results. This research starts from wing design and manufacture as the wind tunnel experiment model for wing flow visualization experiment. The high-lift wings are then set on the Tiger II trainer for flight test verifications. Flight test records on relative variation of height and speed are collected for verification. The relationship between control surface to UAV lift provides further development guideline for better flight performance in Ce-71 series.
