摘要： A three-piece seal assembly is disclosed for sealing cooling air leakage between circumferentially spaced-apart flowpath segments in gas turbine engines. First and second seals are disposed in oppositely facing slots on adjacent flowpath segments, and extend between adjacent flowpath segments to restrict cooling flow between the segments. A third seal member having first and second leg portions in abutting engagement with the first and second seals restricts leakage flow between the gap between the first and second seals.

摘要： A turbine nozzle assembly includes a plurality of nozzle segments and a nozzle support for supporting the nozzle segments. Each nozzle segment includes an outer band, an inner band and at least two vanes disposed between the outer and inner bands. A retention flange extends radially inwardly from the inner band and has a first hole formed therein. The nozzle support includes a recess formed therein and a mounting flange extending therefrom. The mounting flange is disposed in contact with the retention flange and has a second hole formed therein. A pin is disposed in the first and second holes to position the flanges with respect to one another. A pin retainer is disposed in the recess and has a holding flange for retaining the pin in place. The nozzle support includes a substantially conical portion and an air seal integrally formed thereto.
