To reduce a battery capacity for ensuring safety and reduce weight at a low cost in a hybrid rotary wing aircraft of which a rotary wing is driven by chiefly an internal combustion engine.SOLUTION: A hybrid rotary wing aircraft comprises: a first internal combustion engine (31) and a second internal combustion engine (32); three or more rotary wings (21q, 22q, 23q, 24q, 21r, 22r, 23r, 24r) which can be connected via one-way clutches (51q, 52q, 53q, 54q, 51r, 52r, 53r, 54r) and are respectively arranged linearly; and motor generators (41q, 42q, 43q, 44q, 41r, 42r, 43r, 44r) respectively connected to the same. A differential mechanism (38) is interposed between at least two rotary wings (21q, 24q, 21r, 24r) located at both ends of the three or more rotary wings, and the first internal combustion engine (31) and the second internal combustion engine (32).SELECTED DRAWING: Figure 2

    【課題】主として内燃機関で回転翼を駆動するハイブリッド回転翼航空機において、安全確保のためのバッテリを小容量で済ませて、低コストで重量を軽くすること。【解決手段】第1内燃機関(31)及び第2内燃機関(32)と、ワンウエイクラッチ(51q、52q、53q、54q、51r、52r、53r、54r)を介して連結可能な、それぞれ直線状に並んだ3つ以上の回転翼(21q、22q、23q、24q、21r、22r、23r、24r)と、これらとそれぞれ連結したモータ・ジェネレータ(41q、42q、42q、44q、41r、42r、43r、44r)と、を備え、3つ以上のうちの両端に配置した、少なくとも2つの回転翼(21q、24q、21r、24r)と、第1内燃機関(31)及び第2内燃機関(32)との間に、それぞれ差動機構(38)を介在させた。【選択図】図2
