This paper describes a performance analysis and test result of a small gas turbine engine for mini-cogeneration system. Recently turbocharger technology for small gasoline and diesel engines progressed significantly. The compressors and the turbines whose diameter is nearly 35mm are applied to the small turbochargers. The aerodynamic performance of these compressors and turbines becomes high and the reliability and durability are guaranteed. We tried to develop small gas turbine using these small turbochargers. In order to apply turbochargers without any change of construction, we apply two shaft exhaust-heated gas turbine cycle. In this cycle the combustion chamber and recuperator are the key technology. The gas generator turbine is the most small turbocharger with its compressor diameter 36mm, and turbine diameter 35mm. And the generator is planned to attach to the power turbine with its diameter 52mm. The target of electric power is 3kW. And we made a test apparatus to confirm the fundamental operational function.
