To provide an unmanned aircraft that can collect data for determining a propriety of rotation control of propellers of an unmanned aircraft that is performed in accordance with variation in a flight status of the unmanned aircraft.SOLUTION: An unmanned aircraft 2 is provided with a first sensing mechanism 13 for sensing a direction and a speed of airflow generated by respective rotation of a plurality of propellers, and a second sensing mechanism 14 for sensing a direction and a speed of airflow generated due to movement of the unmanned aircraft 2 and disturbance. The first sensing mechanism 13 for sensing a direction and a speed of airflow generated due to rotation of one propeller is arranged at a position where the mechanism is not influenced by airflow due to rotation of the other propeller, and the second sensing mechanism 14 is arranged at a position where the mechanism is not influenced by airflow due to rotation of the plurality of propellers. A data processing part 17 calculates the direction and the speed of airflow generated by respective rotation of the plurality of propellers, on the basis of sensed results by the first sensing mechanism 13 and the second sensing mechanism 14 during flight of the unmanned aircraft 2.SELECTED DRAWING: Figure 1

    【課題】無人航空機の飛行状態の変動に応じて行われる無人航空機のプロペラの回転制御の適否を判断するためのデータを収集することが可能な無人航空機を提供する。【解決手段】無人航空機2は、複数のプロペラのそれぞれの回転によって発生する気流の向きおよび速さを検知するための第1検知機構13と、無人航空機2の移動および外乱に起因する気流の向きおよび速さを検知するための第2検知機構14を備え、1個のプロペラの回転に起因する気流の向きおよび速さを検知するための第1検知機構13は、他のプロペラの回転に起因する気流の影響を受けない位置に設置され、第2検知機構14は、複数のプロペラの回転に起因する気流の影響を受けない位置に設置されている。データ処理部17は、無人航空機2の飛行時の第1検知機構13および第2検知機構14の検知結果に基づいて複数のプロペラのそれぞれの回転によって発生する気流の向きおよび速さを算出する。【選択図】図1
