Abstract: A mold assembly for use in forming a component having an internal passage defined therein is provided. The component is formed from a component material. The mold assembly includes a mold that defines a mold cavity therein. The mold assembly also includes a lattice structure selectively positioned at least partially within the mold cavity. The lattice structure is formed from a first material that has a selectively altered composition in at least one region of the lattice structure. A channel is defined through the lattice structure, and a core is positioned in the channel such that at least a portion of the core extends within the mold cavity and defines the internal passage when the component is formed in the mold assembly.

Abstract: A method of recovering heat energy from a cooling medium used to cool hot gas path components in a turbine engine includes cooling one or more hot gas path components with the cooling medium; supplying spent cooling medium used to cool the one or more hot gas path components to a heat exchanger; supplying air (e.g., compressor discharge air) to the heat exchanger so as to be in heat exchange relationship with the spent cooling medium and thereby add heat to the compressor discharge air; and supplying the air heated in the heat exchanger to at least one combustor.
