Abstract
There is provided by the present invention method and apparatus for damping vibrations or other unwanted motions of a brush seal, the apparatus including a damper having a plurality of individual plates that are bonded directly to the inlet rows of bristles of the seal. Methods for producing a damped brush seal in accord with the present invention contemplate brazing damping plates to the bristles, absorbing a melting point suppressor into the surface of the damping plates and then heating the damping plates until the treated surface melts and bonds with the bristles, or sintering a braze alloy to the bristles such that the braze alloy functions as a damping plate.
