Abstract
A process for casting a turbine engine component is provided. The process comprises the steps of placing a refractory metal core assembly comprising two intersecting plates in a die, encapsulating the refractory metal core assembly in a wax pattern having the form of the turbine engine component, forming a ceramic shell mold about the wax pattern, removing the wax pattern, and pouring molten material into the ceramic shell mold to form the turbine engine component.
