Abstract
Official abstract text for this publication.
A flowpath assembly has a first conduit defining a flowpath radially inward, and a second conduit spaced radially outward from the first conduit. A void defined between the first and second conduits contains an insulating material that may have a greater porosity than the first and second conduits. The assembly may be additive manufactured generally as one unitary piece with the raw material of the conduits being melted and solidified on a slice-by-slice basis and the insulating material being selectively bypassed by an energy gun of an additive manufacturing system.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a flowpath assembly, comprising: electronically modeling the flowpath assembly having a first conduit co-extending along a centerline and radially surrounded by a second conduit with a void defined and radially between the first conduit and the second conduit; additive manufacturing simultaneously the first conduit, the second conduit and a support structure engaged between and connecting the first conduit and the second conduit; and depositing an insulating material in the void during the additive manufacturing of the first conduit, the second conduit and the support structure; wherein the additive manufacturing of the first conduit, the second conduit and the support structure and the depositing the insulating material all include depositing of a powder and the flowpath assembly is electronically modeled into a plurality of slices, each slice having a portion of the first conduit, the second conduit, the support structure and the insulating material, and a first slice of the plurality of slices is manufactured in-part through melting and solidification of the powder before proceeding to the manufacture of a next successive slice of the plurality of slices, and the insulating material is not melted. 2. The method of claim 1 , wherein the support structure and the insulating material are made of the same material composition.
