To scatter materials without frequently landing and taking off.SOLUTION: A manned aircraft 10 having 4 or more rotors 31 to 34 that have pitch adjustment mechanisms 21 to 24 has: a motor 11 outputting a rotary force; a branch part 14 branching the rotary force outputted by the motor and transmitting the rotary force to each of the 4 or more rotors; a cut-off mechanism (a cut-off part 12) which is arranged between the motor and the branch part, cuts the rotors off the motor when no rotary force is supplied by the motor, and rotates the 4 or more rotors at the same angular speed; and a control part 15 controlling flight postures by controlling the pitch adjustment mechanisms in accordance with an instruction from an operator. The control part performs auto-rotation descension by controlling the pitch adjustment mechanisms of the rotors when defect occurs to the power system.SELECTED DRAWING: Figure 2

    【課題】頻繁に離着陸することなく、資材を散布すること。【解決手段】ピッチ調整機構21〜24を有する4以上のロータ31〜34を有する有人航空機10において、回転力を出力する原動機11と、原動機から出力される回転力を分岐し、4以上のロータのそれぞれに回転力を伝達する分岐部14と、原動機と分岐部の間に配置され、原動機から回転力が供給されない場合にはロータを原動機から切り離すとともに4以上のロータを同じ角速度で回転させる切り離し機構(切り離し部12)と、操縦者からの指示に応じてピッチ調整機構を制御することで飛行姿勢を制御する制御部15と、を有し、制御部は、動力系に故障が生じた場合には、ロータのピッチ調整機構を制御することでオートローテーション降下を実行させることを特徴とする。【選択図】図2
