To provide a compound helicopter capable of inhibiting aerodynamic interference between rotors and fixed wings during forward flight and allowing the rotors and fixed wings to exhibit their respective original aerodynamic properties or similar properties.SOLUTION: In a compound helicopter 1 including rotors 3 and fixed wings 4, barrier plates 6 are provided above the fixed wings 4 and between the rotors 3 and the fixed wings 4. The barrier plate 6 is configured not to generate lift during flight. Therefore, the compound helicopter 1 requires no additional power or very small additional power to compensate for deterioration of aerodynamic properties of the rotors 3 and the fixed wings 4, so as to enable improvement of flight efficiency of the entire aircraft.SELECTED DRAWING: Figure 1

    【課題】前進飛行時における回転翼と固定翼との空力干渉を抑制して回転翼及び固定翼にそれぞれ本来の空力性能あるいはそれに近い性能を発揮させることが可能な複合ヘリコプタを提供する。【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、固定翼4の上方で、回転翼3と固定翼4との間の部分に障壁板6が設けられており、障壁板6は、前進飛行時に、揚力を発生させないように構成されている。そのため、複合ヘリコプタ1では、回転翼3や固定翼4の空力性能の低下を補うための追加のパワーが不要になり、あるいは追加のパワーが非常に少なくて済むため、機体全体の飛行効率を向上させることが可能となる。【選択図】図1
