Abstract
A system and methods for reducing vibration in a rotatable member are provided. The system includes a blade tracking sensor, a rotatable member comprising an adjustable aspect, and a control computer. The control computer is configured to determine an axial position of each blade, 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.
