A leaf seal for gas turbine stator shrouds and a nozzle band
A leaf seal assembly (80) is secured to the trailing edge of a shroud segment (68) for sealing between the shroud segment and the leading edge side wall of a nozzle outer band (90). The leaf seal includes a circumferentially elongated seal plate biased by a pair of spring clips (86) disposed in a gr...

| description | A leaf seal assembly (80) is secured to the trailing edge of a shroud segment (68) for sealing between the shroud segment and the leading edge side wall of a nozzle outer band (90). The leaf seal includes a circumferentially elongated seal plate biased by a pair of spring clips (86) disposed in a groove (82) along the trailing edge of the shroud segment to maintain the seal plate in engagement with the flange (88) on the leading edge side wall of the nozzle outer band. The leaf seal plate and spring clips receive pins (89) tack-welded to the shroud segment to secure the leaf seal assembly in place. |
