摘要：1,148,590. Stator blade fixing. GENERAL ELECTRIC CO. July 28, 1966 [Dec. 6, 1965], No. 33870/66. Heading F1T. Stator blades 21 in an axial flow compressor or gas turbine are inter-connected by an arcuate spring member 70 frictionally engaging dovetail grooves 66 in the individual base portions 46 of the blades so as to maintain adjacent bases in abutment and assist vibration damping. The blades are mounted in the stator casing 11 by engagement of flanges 50, 51 on the bases with annular grooves 54, 56 in flanges 53, 55 extending inwardly from the casing. The spring member 70 may engage the inner surface 59 of the casing 11 to urge the flanges 50, 51 inwardly in their mounting grooves 54, 56.
