ABSTRACT:
The invention discloses an improved method and apparatus to statically equalize the span wise and chord wise moments of a detached plurality of radial projections. These detached radial projections are associated with a rotating assembly and constitute the majority of its rotating mass. When installed on the rotating assembly, the balanced radial projections will necessarily produce a center of rotating mass approximately concentric with its axis of rotation, thereby minimizing vibrations associated with its rotation. The method to statically equalize the span wise moments of the radial projections comprises first determining the span wise moment by finding the center of gravity and multiplying the distance from the center of gravity to the plane of attachment of the radial projection to the rotating assembly by its total weight.
