Abstract
A gas turbine blade including a root for connecting to a rotor of a gas turbine, a platform attached to the root defining a side surface and a groove formed in the side surface, and an airfoil including a metallic substrate extending from a surface of the platform to a tip, the airfoil including a pressure side and a suction side meeting at a trailing edge and a leading edge, and a platform impingement plate. The platform impingement plate includes a circumferential edge surrounding a cavity, the edge positioned to contact the platform, a plate surface positioned to from the cavity between the first surface and the plate surface, and a flat member having a face attached to the plate surface and at least one end portion. A gas turbine blade including a platform sealing wire positioned in a groove of the platform is also provided.
