摘要 |
A method of increasing low cycle fatigue life of a turbine nozzle (10) comprising a plurality of stationary airfoils (12) extending between radially inner and outer ring segments (16, 14) comprising a) providing at least one radial passage (22) in each of the plurality of airfoils; b) installing a rod in the radial passage extending between the radially inner and outer ring segments and fixing one end of the rod to one of the inner and outer rings; and c) preloading the rod (56) to compress the airfoil between the inner and outer ring segments. <IMAGE> |
