Abstract
A turbine engine component, such as a turbine blade, has an airfoil portion having a pressure side wall and a suction side wall, a first cooling circuit embedded within the pressure side wall, which first cooling circuit has at least two passageways embedded within the pressure side wall, a second cooling circuit embedded within the suction side wall, which second cooling circuit has at least two passageways embedded within the suction side wall, at least one cooling fluid supply cavity located between the pressure and suction side walls, each cooling fluid supply cavity having at least one projecting portion extending between adjacent ones of the embedded passageways in the first cooling circuit or adjacent ones of the embedded passageways in the second cooling circuit, and each projecting portion communicating with at least one film cooling hole. A method for forming the turbine blade component is also described.
