Abstract
One embodiment of a transition-to-turbine seal () comprises a first, flattened section () adapted to be received in a peripheral axial slot () of a transition (), and a second, generally C-shaped section (). The generally C-shaped section () comprises a flattened portion () near the first, flattened section (), and a curved portion () extending to a free edge (). A fiber metal strip component () may be attached to the flattened portion () to define a first engagement surface adapted to engage an upstream side () of an outer vane seal rail (), and a second engagement surface, adjacent the free edge (), provides an opposed wear surface adapted to engage a downstream side () of the outer vane seal rail (). System embodiments also are described, in which such transition-to-turbine seal () is isolated from a hot gas path () by provision of a plurality of cooling apertures () in the transition ().
