Outward bristle brush seal design for gas turbine application

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...

Summary: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).
