Brittle Materials Design High Temperature Gas Turbine Stator Vane Development and Static Rig Tests. Volume 2

Abstract

The three-piece design concept of a separate airfoil section confined within an inner and outer end cap to produce first stage stator vane assemblies for large industrial gas turbines from brittle ceramic materials was reduced to practice in three design iterations. All of the spring-loaded support structures (the insulator blocks, cushions, metal shoes, seals, pivots and plungers) required to adapt the ceramic vanes to the turbine configuration were developed, manufactured and tested. The Norton Company manufactured all stator vane assembly component parts from hot pressed silicon nitride (HS130/NC132) or hot pressed silicon carbide (NC203). Static rig tests were conducted under cyclic conditions, controlled to simulate a turbine environment in peaking power service at 2200 and 2500 F peak inlet temperature at 0.8 turbine simulation.
