OUTER VANE SUPPORT RING INCLUDING A STRONG BACK PLATE 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) for providing structural support for the row of vanes in the engine section, an aft hook (38), a forward wall (48), and a strong back plate (64). The aft hook extends from an aft side of the main body portion and is coupled to an outer engine casing (22) for structurally supporting the support ring in the engine section. The forward wall extends generally radially outwardly from a forward side of the main body portion. The strong back plate spans between the forward wall and the aft hook and effects a reduction in dynamic displacement between the forward wall and the aft hook during operation of the engine.
