The limit of surging in a multi-stage axial-flow compressor cannot be definitely determined merely from the overall characteristic curve alone. This is attributed to the reason that the internal inertance and capacitance play an important role in the multi-stage axial-flow compressor. In this report, the appearing point of surging in case of involving a system of duct is obtained on the basis of the static characteristics of an axial-flow compressor, by the following two methods. 1) An approximate estimation from the respective inertances and capacitances, when a multistage axial-flow compressor is regarded to be able to be divided into three parts. 2) A strict solution when a multi-stage axial-flow compressor is assumed to have a continuous capacitance distributed along the axial direction.
