In March 1999,R & D of 300 kW class ceramic gas turbine (CGT) project under the New Sun Shine program was finished. At the end of the project, thermal coefficient of higher than 42% was attained for the first time. The coefficient is twice higher than that would be obtained by the metal gas turbines of the same power size. After the project, however, the ceramic gas turbines have never been successful in their commercial use due to lack of durability. Since reliability of ceramic elements tends to increase as the volume of them decrease, for much smaller power class of several 10s kW, we try to establish a more durable ceramic gas turbine. In this report, we will give an outline of R & D of a micro-ceramic gas turbine. The gas turbine system is under construction based on J-850 jet engine, Sophia Precision Co. Ltd.
