Abstract (en)
A stator vane assembly for a compressor of a gas turbine engine, including a stator vane (34) having an inner portion (42) and an outer portion (40), a platform (47) attached to the outer portion (40) of the stator vane (34), a casing (26) for the gas turbine engine, wherein the outer platform (47) of the stator vane (34) is attached to the casing (26) in a manner so that an open area (38) is defined therebetween, and a member (36) positioned within the defined open area (38) for damping vibrations transmitted from the casing (26) to the outer platform (47). The casing (26) may have a split-line configuration so that first and second circumferential flanges (28,30) are mated together, wherein the outer platform (47) is attached to the casing (26) by means of a flange (50) extending therefrom which is positioned between and connected to the first and second circumferential flanges (28,30). 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. <IMAGE>
