To provide a compound helicopter including side propellers which can be operated in highly efficient conditions during hovering and flying forward.SOLUTION: A compound helicopter according to the present technique includes a fuselage, a pair of main wing parts, a main rotor, a first side propeller, and a second side propeller. The main wing parts are provided so as to extend in a lateral direction of the fuselage. The main rotor is provided at an upper part of the fuselage. The first side propeller includes multiple first propeller blades having a first code length distribution and is provided at the main wing part, which is located at the side where the main rotor moves forward, of the pair of main wing parts. The second side propeller includes multiple second propeller blades having a second code length distribution different from the first code length distribution and is provided at the main wing part, which is located at the side where the main rotor moves rearward, of the pair of main wing parts.SELECTED DRAWING: Figure 3

    【課題】ホバリング時及び前進飛行時のいずれにおいても効率が高い条件で運転が可能なサイドプロペラを含むコンパウンドヘリコプタを提供すること。【解決手段】本技術に係るコンパウンドヘリコプタは、胴体と、一対の主翼部と、メインロータと、第1のサイドプロペラと、第2のサイドプロペラとを具備する。前記主翼部は、前記胴体の左右方向に延びるように設けられる。前記メインロータは、前記胴体の上部に設けられる。前記第1のサイドプロペラは、第1のコード長分布を有する複数の第1のプロペラブレードを含み、前記一対の主翼部のうち、前記メインロータが前方に運動する側の主翼部に設けられる。前記第2のサイドプロペラは、前記第1のコード長分布とは異なる第2のコード長分布を有する複数の第2のプロペラブレードを含み、前記一対の主翼部のうち、前記メインロータが後方に運動する側の主翼部に設けられる。【選択図】図3
