隨著無人飛機近十年隨著在美軍在戰場上大量佈署使用的影響下,全球各國針對無人飛機於軍事領域投入大量研發及應用的投資,無人飛機技術的提升使得應用型態已經由傳統偵察演變至可進行對地面目標進行攻擊任務,而取代有人戰鬥機更是無人飛機技術的下一項重要目標。為達到此目的,具備自動化的機動飛行能力以應付[短]距離的空戰將是無人飛機必要發展的技術。本研究期望探討以傳統無人飛機自動飛行系統實現機動飛行能力,藉由追隨由一系列的導航點所構成的機動飛行軌跡而完成機動飛行動作;而軌跡的產生與追隨控制與飛機性能息息相關,本研究將透過一基於線性飛行控制系統的小型高機動性能無人飛機進行機動飛行軌跡與性能分析,並運用建立導航點方式產生機動飛行所需的軌跡。
With the massive deployment of unmanned aircraft in the battle fields by US military in this decade, large investment of research and application from countries around the world has been made for unmanned aircraft in the military domain. The technology advance has been turning the missions of unmanned aircraft from reconnaissance to surface attacking. The next significant objective for unmanned aircraft is to replace the manned fighters. To fullfill this,the autonomy for aerobatic flight to cope with the short-range dog-flight will be one of the critical technologies. This study is expected to explore the possibility of realizing aerobatic maneuvers by using conventional autopilot system for UAVs with the waypoint planning method. Then UAV can perform the aerobatic maneuvers by following the reference aerobatic trajectories constructed by a series of planned waypoints and perform the aerobatic flight. The tracking performance and resulted flight trajectories are seriously related to aircraft performance. To investigate such a innovative way of aerobatic trajectory flight,a small and agile unmanned aircraft with a linear flight control system is used. Then the aerobatic flight trajectories and vehicle performance will be analysed while the reference trajectories will be generated by the technique of waypoint assignment.
