Abstract: The rotor comprises a pendular vibration suppressor with at least two pendulums each having at least one pendular body connected by at least one rigid arm to a support that rotates as one with the rotor hub, and on which the pendulum oscillates via a pivoting connection about an axis of pendular movement spaced away from the center of inertia of the pendulum and from the axis of the rotor, and substantially perpendicular to a radial plane passing through the axis of the rotor and through the center of inertia of the pendulum, which preferably oscillates between two adjacent rotor blades. At least some of the pendulums are tuned to (nb−1)&OHgr; or (nb+1)&OHgr;, so as to attenuate coplanar moments, and other pendulums may be tuned to nb&OHgr;, to filter out forces along the axis of the rotor.
