Case tying means for gas turbine engine

For a gas turbine engine having a compressor section including an axially split outer engine case rotably supporting a drum rotor having axially spaced rows of circumferentially mounted compressor blades, comprising a plurality of axially spaced stator vanes, each stator vane including an outer shroud and a concentrically disposed inner shroud, defining therewith a gas path for the engine's working medium, a plurality of circumferentially spaced vanes disposed between said outer shroud and said inner shroud in said gas path and being disposed between adjacent rows of said compressor blades, hook-like elements extending radially outward from adjacent outer shrouds and spaced from said gas path, a segmented ring-like element defining a rail engaging each of said hook-like elements of adjacent outer shrouds spaced radially from said gas path and said outer engine case, each of said segments of said rail having a first boss and a second boss mounted at either end of said segment and a third boss mounted between said first boss and said second boss, and bolt means extending through openings in said outer engine case threadably engaging said first boss, said second boss and said third boss, whereby said bolt means and said rail support said stator vanes to said outer engine case and said ring-like element being sufficiently flexible in response to engine thermal condition to have virtually no effect on said engine outer case.
