Verfahren zur Herstellung einer reparierten Leitschaufelanordnung einer Turbomaschine und reparierte Anordnung

摘要

A method is provided for making a repaired turbine engine stationary vane assembly (10) including at least one airfoil (16) bonded between spaced apart first and second platforms (12,14). The method comprises providing a first vane assembly member (28) including at least a portion of the first platform (12), the airfoil (16), and a first segment (34) of the second platform (14) bonded with the airfoil (16). Also provided is a second vane assembly member (30) including a second segment (40) of the second platform (14) with a recess (42) of a shape and size sufficient to receive the first segment (34) of the second platform (14). The first segment (34) is placed in the recess (42) after which the first and second segments (34,40) are bonded, for example by brazing or welding. Provided is a more structurally sound repaired turbine engine stationary vane assembly (10) including the first and second vane assembly members (28,30) bonded together.
