<P>PROBLEM TO BE SOLVED: To provide a gas turbine reliable in operation by surely cooling the heat of a stator blade and a moving blade and lessening thermal stress and thermal deformation. <P>SOLUTION: This gas turbine is provided with a cooling passage 2 provided inside of the moving blade 1 and having cooling air flow and a discharge passage 3 connecting to the cooling passage in the moving blade 1 and discharging cooling air out of the moving blade. The discharge passage 3 is installed to discharge cooling air to at least an inner side 121 of an outer side 123 and/or the inner side 121 of a curved surface of a platform 12 of the moving blade 1, and cooling air discharged from the inside of the curved surface of the moving blade 1 in the exhaust passage 3 flows along a surface 122 of a platform 12. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
