Abstract
A system () is provided for sealing a gap () between a transition exit frame () and a vane rail () at a turbine inlet (). The system includes a seal () with a compliant seal member having a generally u-shaped profile to provide a sealing function in an axial direction. The compliant seal member includes a U-shaped inner sheet () securely pressed within a U-shaped outer sheet (). The outer and inner sheets include spaced-apart segments () in a lateral direction which are spaced-apart by misaligned slots () to block passage of air there through. The system may also include wear resistant material () interposed between the seal and the vane rail. A lateral gap between adjacent exit frames may include a plurality of ribs defining valleys and tips, with crushable material disposed between the valleys and tips.
