VANE OUTER SUPPORT RING WITH NO FORWARD HOOK IN A COMPRESSOR SECTION OF A GAS TURBINE ENGINE

摘要

A support ring (30) for a row of vanes (RV4) in an engine section of a gas turbine engine includes an annular main body portion (32) to which the row of vanes is affixed for providing structural support for the vanes in the engine section, a forward wall (48), and an aft hook (38) extending from an aft side of the main body portion with reference to a direction of air flow through the engine section. The aft hook is coupled to an outer engine casing (22) for structurally supporting the support ring in the engine section. The support ring does not include a forward hook having a flange that extends axially from a forward or aft side of the forward hook with reference to the direction of air flow through the engine section. A method for servicing a compressor section comprises removing select material from the outer compressor casing and installing a replacement support ring not having a forward hook.
