Abstract
Official abstract text for this publication.
A flexible, thermal-isolating tube includes a first fluid flow channel portion having a dual-walled configuration, a second fluid flow channel portion having a dual-walled configuration, and a bellows disposed between and coupled to each of the first and second fluid flow channel portions. The flexible, thermal-isolating tube, including each of the first and second fluid flow channel portions, and the bellows, is configured as a unitary structure. The flexible, thermal-isolating tube is manufactured using an additive manufacturing process. The flexible, thermal-isolating tube is disposed within a gas turbine engine.
First claim
Opening claim text (preview).
What is claimed is: 1. A flexible, thermal-isolating tube, comprising: a first fluid flow channel portion having a dual-walled configuration; a second fluid flow channel portion having a dual-walled configuration; and a bellows disposed between and adjacent to each of the first and second fluid flow channel portions, wherein the flexible, thermal-isolating tube, including each of the first and second fluid flow channel portions, and the bellows, is configured as a unitary metallic structure comprising a one-piece configuration such that the unitary structure excludes brazing, fasteners, or fastening means for maintaining parts in a fixed relationship as a single unit, wherein the bellows forms a section of a single-walled configuration between the first and second fluid flow channel portions and extends from an inner wall of the dual-walled configuration of both the first and second fluid flow channels portions. 2. The flexible, thermal-isolating tube of claim 1 , wherein the first and second fluid flow channels each independently comprise an end portion chosen from: a cylindrical end portion or a flange end portion. 3. The flexible, thermal-isolating tube of claim 1 , wherein either or both of the first and second fluid flow channels comprise a curved configuration. 4. The flexible, thermal-isolating tube of claim 1 , configured for carrying oil from a first location to a second location. 5. The flexible, thermal-isolating tube of claim 1 , configured for carrying compressor air from a first location to a second location. 6. The flexible, thermal-isolating tube of claim 1 , comprising a metal super-alloy material.
