Abstract
A turbine vane is provided which includes a radial outer platform, a radial inner platform and an airfoil extending between the outer platform and the inner platform. Each platform has a gas washed surface facing towards the respective other platform, a non gas washed surface facing away from the respective other platform and a peripheral surface extending from the gas washed surface to the non gas washed surface. The peripheral surface includes an upstream section that is designed to be directed towards the gas flow washing the gas washed surface. Cooling fluid channels each include an opening in the peripheral surface or in the gas washed surface and are located in at least a section of the outer platform and/or in at least a section of the inner platform. The respective section directly adjoins the upstream section of the peripheral surface of the respective platform.
