Gas-path leakage seal for a gas turbine made from metallic mesh

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 combustor casing segments). The seal includes a cloth-layer assemblage positioned in the leakage-gap. The cloth-layer assemblage includes a metallic, woven cloth layer having a first group of generally equal-diameter warp wires and a second group of generally equal-diameter weft wires. Adjacent wires of one of the first and second groups of wires are spaced apart by a center-to-center distance equal to generally between four and ten times the diameter of the wires of the other of the first and second groups of wires.
