One embodiment of a transition-to-turbine seal (300) comprises a transition exit seal (302) adapted for fixed attachment to an exit rail (116) of a transition (109), and a stage-1 seal (340). The stage-1 seal (340) comprises an axial seal slot (348) comprising parallel walls (346, 347) adapted to slidingly engage a first male member (310) of the transition exit seal (302). The stage-1 seal (340) also comprises a radial seal slot (354) comprising parallel walls (351, 353) adapted to slidingly engage a plate (338) of a row 1 vane segment (330). The transition-to-turbine seal (300) thus provides both axial and radial freedom of movement. Materials and coatings for the transition exit seal (302) and the stage-1 seal (340) are selected to promote preferential wear of these components relative to wear of the surface of the row 1 vane segment (330). Wear of the exit rail (116) is reduced or eliminated due to the noted fixed attachment.
A transition-to-turbine seal for sealing a gap between an outlet of a gas turbine engine transition and a row 1 vane segment, the transition-to-turbine seal comprising:
A seal kit for a gas turbine engine, the seal kit comprising:
A transition-to-turbine seal for a gas turbine engine comprising a hot gas path passing through a transition to a turbine row 1 vane, the transition comprising an exit rail at its downstream end, and the turbine row 1 vane comprising a radially disposed leading edge rail, the transition-to-turbine seal comprising:
A transition-to-turbine seal for sealing a gap between an outlet of a transition and a row 1 vane segment of a gas turbine engine, the transition-to-turbine seal comprising:
