The development of 100kW ceramic gas turbine components has entered the final stage of the seven-year project and is making satisfactory progress toward the goals. We have attained the interim targets of the aerodynamic performances and have been carrying out tests to improve efficiency further. As for ceramic parts, we have changed the material of the turbine rotor to a new one that is excellent in long-sustained and high-temperature strength properties, and have confirmed the strength at high temperature through hot-spin tests. After evaluating blade-vibration stress through analyses and experiments, we completed an endurance evaluation at 1,200℃ TIT (1,473K) and a rated speed of 100,000rpm. We are now carrying out endurance tests at 1,350℃ (1,623K) TIT. In a full-assembly test, together with other components, we confirmed that the turbine rotor caused no functional problem in tests performed at 1,200℃ TIT level, up to the rated speed (lO0,000rpm).
