More Information
Summary:A gas turbine guide vane segment has a first guide vane part with an aerofoil and a first platform section and a second guide vane part with a second platform section. The first guide vane part and the second guide vane part are separately manufactured parts joined together such that the second platform section defines a leading edge of the gas turbine guide vane segment and such that the first platform section and the second platform section form an aligned common platform surface of the gas turbine guide vane segment. The first platform section includes slots in the first platform section for guiding cooling fluid along a surface of the first platform section for film cooling of the surface, the slots being provided at an upstream bend of the first platform section and the slots are provided on a side of the first platform section facing the working fluid.
