摘要: A method for making a brush seal includes weaving a single-layer bristle assemblage having two spaced-apart cloth segments joined together by an unwoven section wherein the two cloth segments and the unwoven section share a common first group of warp bristles and wherein the two cloth segments have different groups of weft bristles. The method further includes the step of cutting generally across the unwoven section of the first group of bristles to create free ends. The brush seal so made is useful, for example, to generally seal a leakage gap in a gas path of a gas turbine.

摘要: A gas-path leakage seal for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a gas turbine (such as first and second segments of a gas turbine combustor casing). The seal includes a generally imperforate foil-layer assemblage which is generally impervious to gas, is located in the leakage-gap, is spaced apart from the first member, and has a first foil layer. The seal also includes a cloth-layer assemblage contacting the first member and having a first cloth layer generally enclosing and generally enclosingly-contacting the foil-layer assemblage. The first foil layer is made from a metal, ceramic, and/or polymer. The first cloth layer is made from metal, ceramic, and/or polymer fibers. The foil assemblage provides for sealing and flexibility, and the cloth assemblage provides for wear resistance and flexibility. The seal accommodates different surface shapes, assembly misalignment, vibration, and differential thermal growth of the gas turbine members.
