A vibration attenuator (117) for an aircraft (101) has first and second coaxial spinners (121, 133) configured for rotation about a mast axis (115) and relative to a rotor (109). Upper and lower weights of each spinner (121, 133) are spaced radially from the axis (115) and positioned 180 degrees from each other about the axis (115). The weights of each spinner (121, 133) are spaced from each other a distance parallel to the mast axis (115), each weight rotating about the mast axis (115) in a different plane. The spinners (121, 133) rotate together relative to the rotor (109) at a selected angular rate and are selectively rotatable relative to each other between a minimum-moment configuration, in which the upper weight of each spinner (121, 133) is angularly aligned with the lower weight of the other spinner (121, 133), and a maximum-moment configuration, in which the upper weights are angularly aligned and the lower weights are angularly aligned, producing a whirling moment about the mast axis (115) as the spinners rotate(121, 133).
