A system and methods for reducing vibration in a rotatable member are provided. The system includes a blade tracking sensor (62), a rotatable member comprising an adjustable aspect and a control computer (64). The control computer is configured to determine an axial position of each blade (40), determine a first blade that is displaced by a greatest distance along the axis in a first direction, modify an aspect of the first blade to facilitate reducing a vibration in the rotary blade system, determine if the vibration level in the rotary blade system is reduced, and select another rotatable member to modify such that a vibration in the rotary blade system is facilitated being further reduced.

L'invention concerne un système et des procédés pour réduire les vibrations dans un élément rotatif. Le système comprend un capteur de suivi de pale (62), un élément rotatif comprenant un aspect réglable et un ordinateur de commande (64). L'ordinateur de commande est configuré pour déterminer une position axiale de chaque pale (40), déterminer une première pale qui est déplacée sur une distance la plus longue le long de l'axe dans une première direction, modifier un aspect de la première pale, afin de faciliter la réduction des vibrations dans le système à pales tournantes, déterminer si le niveau de vibration dans le système à pales tournantes est réduit, et choisir un autre élément rotatif à modifier de sorte qu'une nouvelle réduction des vibrations dans le système à pales tournantes soit facilitée.
