Apparatus for damping vibrations of the stator vanes of a gas turbine engine

摘要

A stator vane assembly (60) for a gas turbine engine includes a plurality of stator vane sectors (62), each of the plurality of stator vane sectors including an equal number of circumferentially-spaced stator vanes (34) oriented such that a first circumferential spacing (S3) is defined between each pair of adjacent stator vanes within each sector. The plurality of stator vane sectors are coupled together such that a second circumferential spacing (S4) is defined between each pair of adjacent stator vanes coupled to adjacent sectors. The second circumferential spacing is different from the first circumferential spacing.
