structure of closing to estate and support for an orderly disposal part segmented shovels to drive a mtore in gas turbine

摘要

The guide vanes 16 are fixedly supported at their tip portions to an outer shroud 12 while the root portion 20 of each vane is connected to a segment 32 of a radially inner, segmented shroud. Each segment 20 is, in turn, connected via a slip fit interconnection permitting thermal expansion to an L-shaped radially inner ring support structure 40. A spring 70 extends between the segment 20 and the base 42 of the L-shaped support to form a flexible coupling, while the remaining portion of the L-shaped support defines a pressure dam to reduce leakage through the flexible coupling.
