A stator vane assembly for a compressor of a gas turbine engine, including a stator vane having an inner portion and an outer portion, a platform attached to the outer portion of the stator vane, a casing for the gas turbine engine, wherein the outer platform of the stator vane is attached to the casing in a manner so that an open area is defined therebetween, and a member positioned within the defined open area for damping vibrations transmitted from the casing to the outer platform. The casing may have a split-line configuration so that first and second circumferential flanges are mated together, wherein the outer platform is attached to the casing by means of a flange extending therefrom which is positioned between and connected to the first and second circumferential flanges. Alternatively, the casing may have a clam shell configuration so that first and second axial flanges are mated together, wherein the outer platform is attached to the casing by means of a rail member incorporated into an inner surface of the casing.
A stator vane assembly for a compressor of a gas turbine engine, comprising:
A stator vane assembly for a compressor of a gas turbine engine, wherein said gas turbine engine includes a split-line casing having first and second circumferential flanges surrounding said compressor, said stator vane assembly comprising:
A stator vane assembly for a compressor of a gas turbine engine, wherein said gas turbine engine includes a casing surrounding said compressor having a plurality of rail members positioned along an inner surface thereof, said stator vane assembly comprising:
A method of damping vibrations from an engine casing to a stator vane of a compressor connected to said casing, comprising the following steps:
