Abstract
In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner rail of each nozzle segment radially inwardly of the chordal hinge seal. To minimize or prevent leakage flow across the chordal hinge seal, the seal is formed of flexible sheet metal which extends between the inner rail and a seat projecting from the annular sealing surface of the support ring radially inwardly of the chordal hinge seal. A first margin of the flexible seal engages in an arcuate groove carried by the inner rail. The opposite margin extends arcuately in sealing engagement along the seat carried by the nozzle support ring.
