Abstract
One embodiment of a transition-to-turbine seal () comprises a transition exit seal () adapted for fixed attachment to an exit rail () of a transition (), and a stage-1 seal (). The stage-1 seal () comprises an axial seal slot () comprising parallel walls () adapted to slidingly engage a first male member () of the transition exit seal (). The stage-1 seal () also comprises a radial seal slot () comprising parallel walls () adapted to slidingly engage a plate () of a row 1 vane segment (). The transition-to-turbine seal () thus provides both axial and radial freedom of movement. Materials and coatings for the transition exit seal () and the stage-1 seal () are selected to promote preferential wear of these components relative to wear of the surface of the row 1 vane segment (). Wear of the exit rail () is reduced or eliminated due to the noted fixed attachment.
