This paper describes the development of annular-type combustion using reflunet flow for ultra-micro gas turbine. As the definition of an ultra-micro gas turbine, we considered it as the type that applied to the condition of less than 20mm for the impeller diameter. Recently, commercialization of portable power generation system that is composed of an ultra-micro gas turbine engine is expected. As background, the ultra-micro gas turbine power generation system has also some benefits as availabilities for a power generation in an emergency such as a disaster, or for a power source that can support a wide variety of fuel. In this study, the subject is to development of an ultra-micro gas turbine engine characterized by palm size. Design concept of the combustor and flame characteristics using micro-nozzle are discussed in this paper. As a result, we obtained the steady-flame conditions by fuel flow rate, and also a flow-simulation result as a design guideline.
