To provide a radio-controlled rotary-wing aircraft capable of efficiently and surely inspection work without receiving restriction of an inspection object.SOLUTION: A pair of left and right rotors 16A and 16B is provided at both left and right sides of an airframe 12. A drive part 18 rotates the pair of left and right rotors 16A and 16B. A first swing part 20 and a second swing part 22 for swinging the pair of left and right rotors 16A and 16B are accommodated in an upper rear part 1204 through a connection arm 26. When a straight line connecting the pair of rotors 16A and 16B is defined as a pitch axis A, the first swing part 20 integrally swings the pair of rotors 16A and 16B around the pitch axis A at a first angle θ centering on the pitch axis A. When a straight line orthogonal to a middle point between the pair of rotors 16A and 16B on the pitch axis A to connect front to back directions of the airframe 12 is defined as a roll axis B, the second swing part 22 integrally swings the pair of rotors 16A and 16B around the roll axis B at a second angle φ centering on the roll axis B.SELECTED DRAWING: Figure 1

    【課題】検査対象物の制約を受けることなく点検作業を効率的にかつ確実に行う。【解決手段】左右一対のロータ16A、16Bは、機体12の左右両側に設けられている。駆動部18は、左右一対のロータ16A、16Bを回転させる。連結アーム26を介して左右一対のロータ16A、16Bを揺動させる第1の揺動部28と第2の揺動部30とが上後部1204に収容されている。第1の揺動部20は、一対のロータ16A、16Bを結ぶ直線をピッチ軸Aとしたとき、ピッチ軸Aを中心として一対のロータ16A、16Bをピッチ軸Aの回りに一体的に第1の角度θで揺動させる。第2の揺動部22は、ピッチ軸Aにおける一対のロータ16A、16Bの間の中点と直交し機体12の前後方向を結ぶ直線をロール軸Bとしたとき、ロール軸Bを中心として一対のロータ16A、16Bをロール軸Bの回りに一体的に第2の角度φで揺動させる。【選択図】図1
