Abstract
The segmented inner case supporting the stator vanes of the compressor is tied to an axially split outer case of a gas turbine engine by utilizing a segmented ring-like element forming a rail with bosses at either end and intermediate the ends and having a relatively thin resilient body between bosses capable of flexing in response to thermal loads. Bolts extending through the outer case are threaded into the bosses. This arrangement facilitates the assembly and disassembly of the compressor section.
