Gas-path leakage seal for a turbine

A turbine seal assembly comprising:

• a) a first turbine member having a first surface with a first slot;
• b) a second turbine member spaced-apart from said first turbine member so as to define a gas-path leakage-gap therebetween, said second turbine member having a second surface with a second slot generally opposing said first slot;
• and
• c) a gas-path leakage seal for generally sealing said gas-path leakage-gap, wherein said seal is disposed partially in said first slot and partially in said second slot, and wherein said seal includes:
• (1) a flexible and generally imperforate metal sheet assemblage having opposing first and second surfaces and having two opposing raised edge regions and two opposing unraised edges, said unraised edges connecting together said first and second surfaces, and said raised edge regions and said unraised edges defining generally the perimeter of said metal sheet assemblage, wherein each of said raised edge regions extends a generally identical distance above said first surface, wherein each of said raised edge regions extends generally said identical distance below said second surface, wherein one of said raised edge regions is disposed entirely within said first slot, and wherein the other of said raised edge regions is disposed entirely within said second slot;
• (2) a first cloth layer assemblage having a thickness generally equal to said identical distance and superimposed on said first surface between said raised edge regions;
• and
• (3) a second cloth layer assemblage generally identical to, and a separate piece from, said first cloth layer assemblage and superimposed on said second surface between said raised edge regions.
