Through work in two U.S. Department of Energy cooperative programs with industry, the confidence level for utilization of ceramic composite SiC/SiC combustor liners has risen from a prototype curiosity to serious planning and addressing of hurdles for commercialization. One of the most significant hurdles for true commercialization is affordability of the ceramic composite combustor liners. To study the manufacturing costs for CFCC liners, a study was conducted to identify cost items and relationships. This report describes the effort, identifies the high impact areas of manufacturing costs, and recommends potential approaches to reducing the manufacturing costs.
