More Information
Summary:The present invention generally relates to a vane (1) for a gas turbine, and more in particular it provides an innovative vane with improved flexibility leading to a reduction of stresses at the transition from the vane trailing edge (31) to the vane platform (2), without interfering into the cooling scheme of such component. The present invention teaches to increase flexibility of the vane platform (2) by introducing on the vane platform a material cutback (4, 5) confined in the proximity of the trailing edge portion of the vane airfoil.
