Braided wire damper for segmented stator/rotor and method

摘要

The segments of the vanes of a stator and the blades of a rotor for a gas turbine engine are dampened by utilizing braided wire cable that is affixed to adjacent segments such that each of the wire strands forming the cable is allowed to move relative to each other to dissipate the vibratory energy inflicted on the stator or rotor. The ends of the cable are welded or heated and then tapered to facilitate fitting into a sleeve or collar which in turn is affixed to the adjacent segments by braze, weld or the like.
