ABSTRACT:
The flowpath assembly includes inner and outer circular bands 16 and 18, respectively, and a plurality of stator blades 20 extending between the bands. The tip portions 26 of the stator blades and the openings 30 in the outer bands are at least as large as the footprints F of the blades in a radial direction. Thus, the airfoil portions 22 of the blades, which are bowed, tapered and twisted, are receivable through the openings 30 in the outer band 18 during assembly. The tip and root portions 24 and 26, respectively, of the blades are secured in the openings by welding.
