To provide a flight efficiency improving system in a compound helicopter capable of improving flight efficiency during forward flight in the compound helicopter comprising rotors and fixed wings.SOLUTION: In a compound helicopter 1 having rotors 3 and fixed wings 4, the rotors 3 do not perform cyclic pitch operation during forward flight of the compound helicopter 1 so as to allow a difference to be generated in lift L3 between on a forward side 3A and on a backward side 3B, or perform the cyclic pitch operation so limitedly as to allow the difference to be generated in the lift L3 between on the forward side 3A and on the backward side 3B. The fixed wings 4 are provided on right and left sides of a fuselage 2, and right and left fixed wings 4A and 4B are arranged asymmetrically so as to reduce an impact of aerodynamic interference between the rotors 3 and the fixed wings 4.SELECTED DRAWING: Figure 2
【課題】回転翼と固定翼とを備える複合ヘリコプタにおいて前進飛行時における飛行の効率化を図ることが可能な複合ヘリコプタにおける飛行効率化システムを提供する。【解決手段】回転翼3と固定翼4とを備える複合ヘリコプタ1において、回転翼3では、複合ヘリコプタ1の前進飛行時にサイクリックピッチ操作を行わずに前進側3Aと後退側3Bとの間で発生する揚力L3に差が生じることを許容し、又は、前進側3Aと後退側3Bとの間で発生する揚力L3に差が生じることを許容する程度にしかサイクリックピッチ操作を行わず、固定翼4は、胴体2の左右に設けられており、回転翼3と固定翼4との空力干渉の影響を低減するように左右の固定翼4A、4Bが非対称化されている。【選択図】図2
