Document Type and Number:
WIPO Patent Application WO/2018/151516
Kind Code:
A1
Abstract:
An apparatus for suppressing vibration of a helicopter blade is disclosed. The apparatus for suppressing vibration of the helicopter blade according to the present invention comprises a blade fixing part for blades having different natural frequencies and coupled to a rotor system of a helicopter. According to the present invention, since only the blade fixing part is deformed to prevent vibration between blades, easy application to all helicopters is possible. In addition, since only the blade fixing part is deformed, a change in overall lift or weight balance can be almost ignored. As a result, vibration can be removed by 90% to the maximum by suppressing resonance between blade natural frequencies.
