Abstract

The gas-path leakage seal is provided for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a turbine. The seal includes an elongated seal member (10) having an elongated, imperforate, and flexible first portion (16), and a rigid second portion (18) that defines a mounting bracket (22). The first portion has first and second surfaces (28) and raised longitudinal edges (32, 132) that extend a generally identical distance above the first surface and generally the aforesaid identical distance below the second surface. A cloth layer (40) having a thickness generally equal to or slightly greater than the aforesaid identical distance is superimposed on the second surface between the raised edges (32, 132).
