Abstract
A turbine blade includes a platform and an airfoil having a plurality of trailing edge slots separated by land areas larger than the slots. The slots have an exit diffusion half angle of about two degrees. Cooling air flows through the slots and over a trailing edge of the airfoil. The platform includes a plurality of openings extending through the platform at an angle. The openings are positioned between a suction side of the blade and a second end of the platform. The openings transport disk post cooling air to a surface of the platform and provide cooling for the platform.
