  • Device for reducing the vibrations generated by a lift rotor of a rotary-wing aircraft
    Patent number: 6045090
    Abstract: The present invention relates to a device for reducing the vibrations of the rotor of a rotary-wing aircraft, having an oscillating mass (M1), elastically held radially on the hub (4) of the rotor in the vicinity of its axis (X-X) and fixed to an articulated rod (10) substantially longitudinal to said axis (X-X).According to the invention, said device includes:an adjustment oscillating mass (M2), mounted so that it can move on the rod (10) and having an adjustment position for which the frequency of the resonator formed by said oscillating masses (M1, M2) is matched to the frequency of said vibrations; anddrive means (18) for bringing the adjustment oscillating mass (M2) into said adjustment position.
