In order to establish the design methodology of ultra micro centrifugal compressor, which is the most important component of ultra micro gas turbine unit, a 10 times size of the final target model was designed, prototyped and tested. A 2-dimensional impeller was chosen as the first model due to its productivity and the experiment was done by using a turbocharger for automobile. The performance characteristics were measured and compared with the prediction. The stress and the vibration analysis in the operating condition were also performed. Then, a 5 times and a 2.5 times model with a full 3-dimensional shape were designed and prototyped by a precise stereolithograhy method.
