PROBLEM TO BE SOLVED: To provide a multi-rotor helicopter that is mounted with a conventional electric rotor which is driven by an electric motor serving as main power for the mult-rotor helicopter and further mounted a main rotor which is driven by a fuel type reciprocal engine, which allows long-time and long-distance flight of the mult-rotor helicopter and security of a payload to be achieved, by making the two rotors undertake different roles respectively to further hybridize the rotors.SOLUTION: A mult-rotor helicopter 1 adopts the following means: an airframe having a hollow part 21 at a center thereof; a plurality of control rotors 43 and 63, which are driven by electric motors 44 and 64, arranged around the airframe with the rotary shafts of the rotors pointed in a vertical direction; and a main rotor 22 which is driven by a fuel type reciprocal engine 24 arranged at the hollow part 21 at the center, with the rotary shaft thereof pointed in the vertical direction.SELECTED DRAWING: Figure 3

    【課題】従来のマルチロータヘリコプタの主たる動力となる電動モータ駆動の電動ロータに加えて、燃料式レシプロエンジンにより駆動されるメインロータを搭載し、この2つの動力にそれぞれ異なる役割を持たせて動力のハイブリッド化を行い、マルチロータヘリコプタの長時間・長距離飛行とペイロードの確保の実現を可能とするマルチロータヘリコプタを提供する。【解決手段】マルチロータヘリコプタに次の手段を採用する。第1に、中央に中空部21を有する機体とする。第2に、該機体の周辺に電動モータ44,64により駆動される複数の制御ロータ43,63をその回転軸を垂直方向として配置したマルチロータヘリコプタ1とする。第3に、上記中央の中空部21に燃料式レシプロエンジン24で駆動されるメインロータ22をその回転軸を垂直方向として配置する。【選択図】図3
