Abstract
A turbine nozzle has a metal inner shroud that is joined to a metal outer shroud by a limited number of metal blades for structural purposes, and includes a plurality of air flow guidance vanes made of ceramic material and connected to the shrouds by spring clips. The composite structure allows the turbine nozzle to operate at higher temperatures with less cooling.
