    Gas turbine power generation systems are clean and economical power generation facilities and have become more important because they are power generation facilities that can not only meet the base load but also follow fluctuation of electric power demand under a background in recent years where use of natural energy have expanded. Mitsubishi Heavy Industries, Ltd. (MHI) is currently developing elemental technologies for 1700°C-class gas turbines as a project subsidized by the New Energy and Industrial Technology Development Organization (NEDO) with the aim of further enhancement in the efficiency of gas turbines. For improvement in the efficiency of the gas turbine cycle of axial flow compressors for 1700°C-class gas turbines, it is necessary to increase the pressure ratio, enhance the performance and extend the stable application range. For the verification of compressor performance, eight-stage compressor model test equipment was developed. This paper describes the developed test facility in the subsidized project and the development progress of a measurement technology to which a 3D metal printer is applied.
