Characteristics and ratings of the individual engine components are discussed as well as the assembled engine. The FT9 design incorporates the modular replacement concept. Modular replacement permits replacement of short-life components such as the hot-section without removing the engine from its mounts. The FT9 specification requires development of a condition monitoring system as an integral part of the engine development. Thus, provisions for sensor installations are incorporated in the design. Accelerometers are installed on the internal engine bearing housings to provide improved vibration signals. The engine life-limiting component is the hot- section because of the susceptibility of the blade and vane materials to sulfidation/oxidation at the temperatures encountered with the advanced engines. Sophisticated blade and vane cooling is used to allow high turbine inlet temperatures while keeping blade metal temperatures in a region where sulfidation/oxidation is only moderately active.
