Abstract

A cooling segment (11) includes a segment body (342) and a cooling flow path (344) provided in the segment body, so that a cooling medium is movable in the cooling flow path. The cooling flow path comprises a first twist flow path (344a) helically extending around a preset reference line, and a second twist flow path (344b) helically extending around the reference line collectively with the first twist flow path. A gas turbine (10) includes a compressor (100) configured to suck in and compress air; a combustor (200) configured to mix the air, which is compressed by the compressor, with fuel and combust an air-fuel mixture, and a turbine (300). The turbine includes a turbine casing (310), a turbine vane (330) provided on an inner surface of the turbine casing, a turbine blade (320) rotatably provided in the turbine casing, and the cooling segment (11) provided on the inner surface of the turbine casing and configured to be exposed to combustion gas discharged from the combustor.
