ABSTRACT:
A turbine engine component has an airfoil portion with a pressure side and a suction side. The turbine engine component further has a first cooling microcircuit for cooling the suction side of the airfoil portion. The first cooling microcircuit is embedded within a first wall forming the suction side. The first cooling microcircuit has a circuit for allowing a cooling fluid in the first cooling microcircuit to exit at a tip of the airfoil portion. The turbine engine component also has a second cooling microcircuit embedded within a second wall forming the pressure side of the airfoil portion.
