The focus of this thesis is to investigate alternative approaches to measure temperature and strain in the gas turbine engines. Within the hot section of gas turbine engines most components are made of nickel based superalloys however, next generation gas turbine engines will utilize ceramic matrix composites (CMCs) in the hot section. The CMCs consist of ceramic strand bundled into fibers and the fibers are then woven and embedded in a continuous ceramic matrix. Traditionally ceramic materials were not used for engine components because they were not lack ductility which is important with the shear and tensile forces that the engine components experience. Due to their superior thermomechanical properties, CMCs will soon replace nickel superalloys. The ability to instrument the CMC components with conventional wire based instrumentation including flame spray and thermal spray instrumentation is not an option for CMCs.
