In Japan, research and development of a 100kw Automotive Ceramic Gas Turbine (CGT) has been carried out in the Petroleum Energy Center (PEC) with active cooperation of petro-leum, automobile, ceramics and other related industries. We take charge of the research and development of a centrifugal compressor with variable inlet guide vanes for CGT engines. It is demanded that the compressor has a high efficiency and a wide flow range. The compressor performance goals are an adiabatic efficiency of 81% and a surge margin of 8% under maximum power operating condition. This paper describes the methods for designing an impeller, a diffuser, and variable inlet guide vanes, and presents the results of compressor performance test. The test results show that the surge margin and compressor efficiency at partial load are improved by means of inlet guide vanes.
