CGT303 is a two-shaft regenerative ceramic gas turbine with rotary heat exchangers for the purpose of mobile power generator. It is also widely adaptable for industrial machinery and construction machinery as well. The development program of CGT303 is funded by the New Energy and Industrial Technology Development Organization (NEDO). The maximum output power of 300 kW and thermal efficiency of 42 percent at TiT 1350°C are the objectives of this development. The high TiT requires all gas passage components to be made of ceramics that are designed appropriately to keep sufficient strength by using sophisticated computer analysis. Hot spin tests on ceramic turbine rotors and thermal shock tests on stationary ceramic components have been carried out to prove their strength. The paper covers the design concept of CGT303 and results of analysis.
