PROBLEM TO BE SOLVED: To provide a control method for a pilotless aircraft which is designed to considerably reduce a risk of crash.SOLUTION: Upon detection of emergency, a compressed air tank 5 mounted in a drone 1 causes a nozzle 6 to inject compressed air 7 toward ground so as to ensure landing at a decreased drop velocity. A risk of crash can be considerably decreased even during abnormality, such as a breakdown, without imposing a limit to a flight area of the drone. An abnormality detection part, which monitors all the time together with a controller as to whether an abnormality state occurs, detects abnormality and determines the risk of crash, thus performing control to send an instruction to the compressed air tank so as to perform injection to the nozzle.SELECTED DRAWING: Figure 3
【課題】墜落の危険を大幅に減少させた無人航空機の制御方式を提供する。【解決手段】ドローン1に搭載した圧縮空気タンク5が非常時を検知してノズル6から圧縮空気7を地上に向けて噴射させ落下速度を落として着地させる。ドローンの飛行エリアに制限を与えることが無く、故障などの異常時でも墜落のリスクを大幅に減少させることができる。コントローラーと異常状態に陥ったかを常時監視している異常検知部で異常を検知して墜落の危険を判断し圧縮空気タンクにノズルへ噴射するように指示を出す制御をする。【選択図】図3
