Abstract
A two-shaft gas turbine includes a compressor, a high-pressure turbine including a first shaft connected to a rotation shaft of the compressor, a low-pressure turbine including a second shaft separate from the first shaft, and is provided coaxially to the high-pressure turbine with an interval in an axis direction between the low-pressure turbine and the high-pressure turbine, an intermediate flow path provided between a final stage rotor blade of the high-pressure turbine and a first stage rotor blade of the low-pressure turbine in the axis direction, the intermediate flow path being configured to supply a combustion gas from the high-pressure turbine to the low-pressure turbine, and a strut disposed inside the intermediate flow path. The strut concurrently functions as a first stage stator blade of the low-pressure turbine.
