Title:
VIBRATION INHIBITION SYSTEM IN COMPOUND HELICOPTER
Document Type and Number:
Japanese Patent JP2021187327
Kind Code:
A
Abstract:
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
