The ceramic vane effort seeks to determine structural issues, and the benefits arising from replacing conventional metallic vanes with Ceramic Matrix Composite (CMC) vanes. CMC vanes have increased temperature capabilities, and this can result in improved efficiency, and significant reductions in NOx pollution. A typical CMC vane is formed from a woven Silicon Carbide(SiC) fabric, and has lower strength in the direction normal to weave. Different High Pressure Turbine (HPT) vane configurations have been analyzed to determine stresses in all three directions. The results of these analyses point the way to designing CMC vanes with acceptable stresses for future engine applications.
