To provide a vibration inhibition system in a compound helicopter capable of effectively inhibiting vibration caused by rotation of rotors in the compound helicopter comprising rotors and fixed wings.SOLUTION: In the vibration inhibition system in a compound helicopter 1 having rotors 3 and fixed wings 4, the fixed wing 4 has a movable wing piece 41 at a trailing edge portion. The movable wing piece 41 is periodically operated to periodically change lift generated on the fixed wing 4, so as to aerodynamically generate vibration having a phase opposite to that of vibration generated by rotation of the rotors 3.SELECTED DRAWING: Figure 1

    【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回転翼の回転により生じる振動を効果的に抑制することが可能な複合ヘリコプタにおける振動抑制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における振動抑制システムにおいて、固定翼4は、後縁部分に可動翼片41を備え、可動翼片41を周期的に動作させて固定翼4に生じる揚力を周期的に変化させることで、回転翼3の回転により生じる振動とは逆位相の振動を空力的に生じさせるように構成されている。【選択図】図1
