CGT301 ceramic gas turbine is being developed under a contract from NEDO as a part of the New Sunshine Program of MITI to improve the performance of gas turbine for co-generation through the replacement of the hot section components with ceramic parts.

CGT301 is a recuperated, single-shaft ceramic gas turbine. We have been developing some unique technologies, such as the “hybrid” rotor, composed of a metal disk and inserted ceramic blades, considering the future applicability to larger gas turbines.

We could attain the good engine performance with the primary type CGT at a TIT of 1,200°C. The reliability of the hybrid rotor was confirmed at a TIT of 1,350°C on the test rig.

We conducted preliminary tests using the primary type CGT to extract the possible problems derived from the higher TIT. Some modifications were made and the engine operation at a TIT of 1,280°C was conducted successfully.

On the basis of those experiences we finished the design and fabrication of the pilot CGT.

This paper presents the progress in the development of CGT301.
