Abstract
A method for making a cooled component for a turbine engine includes casting an airfoil assembly having an airfoil with an airfoil cooling passage and extending from a platform with at least one platform cooling passage, and forming a connecting passage between the airfoil cooling air passage and the platform cooling air passage via a tool inserted into a breakout opening in a slashface of the platform.
Claims22
A method of making a cooled airfoil assembly for a turbine engine, the method comprising:
- casting an airfoil assembly having an airfoil extending from a platform, an airfoil cooling air passage, and a platform cooling air passage having a breakout opening in a slashface of the platform;
- inserting a tool into the breakout opening and forming a connecting passage through a wall of the platform cooling air passage and into the airfoil cooling air passage via the tool, thereby fluidly coupling the airfoil cooling air passage and the platform cooling air passage;
- and
- closing the breakout opening.
