Abstract
A turbine blade or vane for a gas turbine has successively along a radial direction of the gas turbine, a root for attaching the turbine blade or vane to a carrier, a platform, an aerodynamically shaped hollow airfoil with a suction side wall and a pressure side wall extending with respect to the direction of a hot gas flow from a common leading edge to common a trailing edge and extending transversely thereof from the platform to an airfoil tip. The airfoil has at least one cooling cavity extending in a cooling fluid flow direction from a platform level to the airfoil tip, the cooling cavity in fluid connection with a number of cooling fluid outlets distributed along the trailing edge through an array of impingement cooling features located therebetween. The array extends into a region which is located radially outside the airfoil within the platform having impingement cooling features.
