Shroud for variable vane structure in a gas turbine engine

摘要

A shroud (30) for supporting a variable vane (26) in a compressor section (18) for a gas turbine engine includes a pair of components (40, 42) which are secured together by a threaded fastener (62) extending into a blind hole (60) in one of the two components (40, 42). Additional material (54) forms on the component (42) which includes the blind hole (60) extends beyond a pivot axis for the vane (26) such that there is an increased length of engagement between the threaded fastener (62) and the blind hole (60). The blind hole (60) eliminates the need for multiple nuts and reduces the radial height of the shroud (30) to save additional weight.
