<P>PROBLEM TO BE SOLVED: To provide a gas turbine stator vane that includes partition members which prevent film cooling air from being leaked to adjacent sections and are applicable to a three-dimensionally designed vane, and enhances the sealing performance of the partition members. <P>SOLUTION: The gas turbine stator vane includes: a hollow airfoil 20 having film cooling holes 25 communicating with the outside; inserts 23 having a plurality of through-holes on the surface and inserted into cavities 21 of the airfoil 20; and each of the partition members 30 that partitions a space defined by hollow inner wall surfaces 21a of the airfoil 20 and outer surfaces of the inserts 23 into two or more parts. The partition members 30 are at least partially composed of elastic bodies. <P>COPYRIGHT: (C)2013,JPO&INPIT |
