Abstract
The mechanical damper is fabricated from a relatively thin metal spring stock and formed in cross-section to an E-shape that is arcuately bent into a ring that fits into the cavity defined between the inner diameter of the inner shroud and the outer diameter of the segmented back rings of the honeycomb sealing structure of the stator for the compressor of a gas turbine engine. The E-shaped damper is segmented and provides damping of the compressor stator of a gas turbine engine and is particularly adapted for stators that are formed from integrally cast stator vanes and shrouds.
