摘要： In a gas turbine having a chordal hinge seal between an inner rail (52) of each nozzle segment and an annular axially facing sealing surface (54) of a nozzle support ring (44), a supplemental seal (70) is disposed between the support ring and inner rail of the nozzle segment on a high pressure side of the chordal hinge seal. The supplemental seal includes a sheet metal seal supported by a bracket secured to the back side and radial inner surfaces (79, 80) of the inner rail. The sheet metal seal has a flexible margin (86) which is preloaded and bears against the annular sealing surface of the nozzle support ring. The bracket is bolted (96) or welded to the inner rail with the sheet metal seal therebetween inhibiting or precluding leakage past the back side of the supplemental seal.

摘要： A brush seal assembly (10) for use between two stationary turbine components (38,48) includes a plurality of arcuate carrier segments, each having a front plate (12) and a back plate (14) having substantially equal radial length dimensions, and a bristle pack (26) sandwiched therebetween. The front plate and the back plate define a hook portion (16) adapted to be received in an annular slot in a first radially inner turbine component, the bristle pack extending substantially radially outwardly beyond the front and back plates and supported by the back plate (14) along the entire radial length dimension and by the front plate along a minor portion (30) of the radial length dimension, thereby leaving an axial gap (34) between the bristle pack (26) and the front plate (12) along a major portion of the radial length dimension. The bristle pack (26) is fixedly secured to the back plate (14) and the front plate along the minor portion (30) of the length dimension, and the bristle pack (26) is slanted in a circumferential clockwise or counterclockwise direction and adapted to sealingly contact a second radially outward turbine component (48).
