Abstract: PROBLEM TO BE SOLVED: To provide a comparatively simple cooling flow passage for rear end area of a stator vane. SOLUTION: A platform for the stator vane includes a meandering flow passage 168 for cooling fluid including two paths 169, 170 provided in the rear end area of the vane. The meandering flow passage 168 extends to a side, folds back and makes flow flowing backward. An endmost part of the meandering flow passage 168 is adjacent to the rear end 134 so as to accept at least the half flow flowing into the flow passage 168 and to discharge the flow through a gas flow passage surface and the rear end 134 of the platform.

Abstract: A coolable stator vane 46 having a platform 48, 54 having internal cooling for the platform is disclosed. Various construction details are developed for cooling the interior of the platform in the trailing edge region 126, 146 of the platform. In one particular embodiment, the platform has a two-pass passage 168 in flow communication with the exterior of the platform, the rearmost pass 170 discharging more than half the cooling fluid entering the two pass passage.
