Ceramic vanes significantly improve erosion resistance of small gas turbines. Methods of economically manufacturing ceramic vanes and associated metal shrouds were developed. Nozzle performance was verified for corrosion, thermal shock, and erosion. Detailed cost studies have shown a ceramic vane nozzle can be built for 150 percent of the cost of a metal vane nozzle. Production tooling has been ordered and engine qualification is planned.
