Stator vane assembly

摘要

A stator vane assembly for a compressor or turbine of a gas turbine engine. The stator vane assembly comprises a plurality of circumferentially-spaced stator vanes extending in a generally radial direction between radially spaced co-axial annular walls mounted co-axially on a rotor of the compressor or turbine. The vanes are flexible and are engaged at at least one position in the radial length thereof by an axially movable annular vane-deflecting member, whereby the vanes are deflectable in cross-sectional shape depending upon the axial position of the vane-deflecting member.
