Gas-path leakage seal for a gas turbine

A gas-path leakage seal for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a gas turbine, said seal comprising:

• a) a generally imperforate foil-layer assemblage consisting essentially of material selected from the group consisting of metals, ceramics, and polymers, generally impervious to gas, disposed in said gas-path leakage-gap, spaced apart from said first member, having a foil-assemblage edge and generally opposing first and second foil-assemblage outer surfaces extending to said foil-assemblage edge, and having a first foil layer wherein said first foil layer has a lengthwise direction and wherein a cross section of said first foil layer normal to said lengthwise direction does not itself completely enclose other structure;
• and
• b) a woven, non-impregnated, cloth-layer assemblage generally pervious to gas, contacting said first member, and having a first cloth layer covering and contacting generally the entire first foil-assemblage outer surface, and covering and contacting generally the entire second foil-assemblage outer surface, wherein said foil-layer assemblage consists essentially of material selected from the group consisting of metals, ceramics, and polymers, and wherein said first cloth layer covers generally the entire foil-assembly edge.
