Abstract

According to one aspect of the invention, a turbine airfoil (200) includes a platform (202) and a blade (204) extending from the platform (202). The airfoil (200) also includes a slot (208) formed in a slashface (210) of the platform (202), the slot (208) being configured to receive a pressurized fluid via passages (212) and configured to direct the pressurized fluid to a selected region of the turbine airfoil (200). The pressurized fluid forms a barrier to restrict the flow of hot gas accross the slashface (210), thus improving the airfoil life. And corresponding method for controlling the temperature of the airfoil.
