Abstract: A heat exchanger assembly for a gas turbine engine that includes an outer engine case. The heat exchanger assembly includes at least one cooling channel, the at least one cooling channel is configured to receive a flow of fluid to be cooled. At least one first coolant flow duct that is configured to receive a flow of a first coolant, wherein the at least one cooling channel is disposed between a first inlet and a first outlet. The heat exchanger assembly further include at least one second coolant flow duct that is configured to receive a flow of a second coolant, wherein the at least one cooling channel is disposed between a second inlet and a second outlet.

Abstract: A method, apparatus, and program for additive manufacturing. The additive manufacturing device includes a positioning mechanism configured to provide independent movement of at least one build unit in at least two dimensions. The build unit may further include a gasflow device for providing a flow zone along a first direction with relation to the build unit. The build unit may further include a powder delivery mechanism and an irradiation beam directing unit. The irradiation bean unit may follow a first irradiation path, wherein the first irradiation path forms at least a first solidification line and at least a second solidification line formed at an angle other than 0° and 180° with respect to the first solidification line. During the formation of the first solidification line, the build unit may be positioned in a first orientation such that the first direction of the flow zone is substantially perpendicular to the first solidification line. During the formation of the second solidification line, the build unit may be positioned in a second orientation such that the flow zone along the first direction is substantially perpendicular to the second solidification line.

Abstract: The additive manufacturing device includes a positioning mechanism configured to provide independent movement of a build unit in at least two dimensions. The build unit may include a gasflow device for providing a flow zone and an irradiation beam directing unit. The irradiation beam directing unit may form a first solidification line and form a second solidification line at an angle other than 0° and 180° with respect to the first solidification line. During the formation of the first solidification line, the build unit may be positioned in a first orientation such that the first direction of the flow zone is substantially perpendicular to the first solidification line. During the formation of the second solidification line, the build unit may be positioned in a second orientation such that the flow zone along the first direction is substantially perpendicular to the second solidification line.
