近年來，地球上自然災害頻傳，不管是地震、颱風、土石流、水患等問題，災害發生時第一現場的災情掌握，將影響救難人員能否進入第一現場，所以災情現況的即時掌握是一項重要的課題。在多次的救災行動情境當中，證明無人飛機的使用是一項有效的方法，常較衛星影像及載人飛機更能有效掌握災情現況。然而，目前多數的多旋翼無人飛行載具大多抗風能力較差，導致雨天時無法使用此載具進行偵蒐行動。本研究將介紹一種針對遙測系統具護罩式的四旋翼機無人飛行載具其開發設計與製作方式，並藉由抗風測試及模擬的降雨測試等方式，探討四旋翼飛機在抗風雨能力，驗證此開發的無人飛行載具在5級風及小雨情況也可執行任務。使未來對災害防治、監測、海洋或森林資料的收集探測與保護，以及監控多種災害現場能現場及廣播等工作，更能獲得即時回報及防救災效能的提升。

The news of disasters were reported frequently, including earth quake, typhoon, flooding, etc. The local situation at the disasters is the most important information to be known by the rescue personnel. It is proved as an effective method even better than satellite and manned aircraft to utilize unmanned vehicle to transfer images from the disaster area to collect more information before and during the action of salvage. However, most unmanned vehicle of multi-axis rotors can't sustain strong wind and raining weathers, which will be limited in its utilization during the investigation. This research is aimed to develop a shrouded quadrotor which may be used in a certain circumstance of wind and rain by proving its performance from the designed 5-grade wind and rain condition. This can be used in the future disaster prevention, monitoring, ocean/forest data collection and protection, and reconnaissance/broadcast from many disaster areas, and enhance the performance of rescuing action.
