Abstract: Disclosed is a compliant seal arrangement 50 for restricting leakage through a gap between a first 54 and second 56 component. A seal assembly 58 is formed by stacking leaf strips 70 flat and sandwiching the stacked leaf strips 70 between a back plate 76 and a side plate 78. The leaf strips 70 are secured to the plates at a joint 84 along an edge 86 of the strips 70 that are in contact with the plates 76, 78. The seal assembly 58 is installed across the gap 52 to form the seal arrangement 50. The strips 70 extend from the first component 54, bridge the gap 52 and contact the second component 56, thereby restricting the leakage of fluid through the gap. Because the strips 70 are compliant, relative motion between the components 54, 56 deflects the strips 70, not causing permanent deformation.

Abstract: Brush seals 30 are secured to segmented vane platforms 20. Inwardly extending bristles 42 seal against rotor 10. Outwardly extending bristles 46 seal against the vane platform 20, and also act as vibration dampers.
