摘要 |
A method for casting an airfoil for a turbine engine is provided. The method includes forming a casting core to define a hollow portion in the airfoil and forming a print out region at one end of the casting core. The method also includes coupling the casting core to the print out region with at least one frusto-conical member to facilitate structurally supporting the casting core.
