Abstract (en)
[origin: EP0475771A1] The last stages of a compressor section of a gas turbine engine that utilizes a drum rotor (12) and segmented stator supported to an axially split outer case (20) suspends the segmented stator case (120) to a full hoop outer case (34) in such a way that the segmented stator may displace axially and thermally grow circumferentially while being constrained radially. A method of assembly and disassembly of the full hoop outer case is provided. A hook (126) on the inner case engages with a groove provided in a support member (120) on the outer case (34). Lugs (127) engage on either side of the hook (126) to prevent rotation. A spool and bolt assembly (50,62) attaches the outer case (34) to the inner case (22). In a method of assembly, a slidable support fixture is temporarily attached to the engine and slides the outer case into position, after which the fixture may be removed. <IMAGE>
