Stator anti-rotation device

摘要

A stator vane assembly for a gas turbine engine is disclosed and includes a plurality of vanes received within channels defined within a case. An anti-rotation plate extends from a flange of the case between adjacent ones of the plurality of vanes for preventing rotation of the plurality of vanes relative to the case.

主权项

1. A compressor section of a gas turbine engine comprising:
a case including a first flange attached to a second flange parallel to an engine axis; a stator vane assembly including a plurality of vanes received within channels defined within the case, wherein each of the plurality of vanes includes a platform section including a side parallel with the engine axis and hooks mounted within the channels; and an anti-rotation plate extending from one of the first flange and the second flange between adjacent ones of the plurality of vanes and abutting the side parallel with the engine axis for preventing rotation of the stator vane assembly, the anti-rotation plate including a mount portion disposed within a recess within one of the first flange and the second flange and a key portion extending radially inward between adjacent ones of the plurality of vanes, wherein the mount portion includes a width greater than the key portion with the anti-rotation plate abutting a side of the hooks within the channels.
