MOUNTING APPARATUS FOR LOW-DUCTILITY TURBINE NOZZLE

摘要

A turbine nozzle (10) includes: an arcuate inner band (12) having opposed flowpath and back sides, and an aft flange (22) extending outward from the back side; an arcuate outer band (14) having opposed flowpath and back sides; an airfoil-shaped turbine vane (16) extending between the flowpath sides of the inner and outer bands, wherein the inner and outer bands and the vane (16) comprise a ceramic low-ductility material; and a metallic collar (34) surrounding the aft flange (22).
