Justification for the allocation of major resources to develop the ceramic gas turbine engine requires a reasonable prospect of obtaining significant improvements in engine performance, durability, reduction in critical materials use, and cost savings on a comparative basis to current-art metal gas turbine engines. Improved engine durability at existing operating conditions is the Navys top priority for materials development. Ceramics have much greater resistance to hot-corrosion than metal alloys. Hot-corrosion of hot-section components is life-limiting engines. Ceramic hot-section components would be much more able to withstand hot-streaking, i.e., carbon burning on the vane air foil surface. These corrosion and thermal properties of ceramics would provide a much expanded tolerance for fuel impurities or with the synthetic fuels anticipated in the 1980s.
