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.

Devices (herein 'powder spreadability inspection tools') and methods are provided for evaluating the spreadability of powders utilized in additive manufacturing (AM) processes. In embodiments, the powder spreadability inspection tool includes a powder support surface on which a visual inspection area is provided, a spreader system including a spreader implement, and a powder dispenser. The spreader implement is movable relative to the powder support surface along a path, which extends or passes over the visual inspection area. The powder dispenser is operable to dispense a premeasured or metered volume of an AM powder sample onto the powder support surface ahead of the spreader implement. As the spreader implement moves along the path relative to the powder support surface, the spreader implement spreads a layer of the metered powder sample across the visual inspection area to allow a visual evaluation of the spreadability of the AM powder.

Additive Manufacturing Quality Management (AMQM) systems and methods are provided, which enhance quality control across Additive Manufacturing (AM) supply chains from which AM components are obtained. In various embodiments, the AMQM system includes an AM machine utilized to produce AM components in accordance with AM design data. A first sensor is coupled to the AM machine and, during fabrication of AM components by the AM machine, captures sensor readings pertaining to the AM fabrication process. When executed by a processor, computer-executable code causes the AMQM system to: (i) compile part-specific sensor profiles from sensor readings captured by the first sensor during fabrication of the AM components, and (ii) generate user notifications indicating whether remedial action should be performed for any of the AM components based, at least in part, on conformance of the part-specific sensor profiles with a baseline sensor profile corresponding to the AM design data.

A method for manufacturing a metallic article includes providing or obtaining a metallic material in powder form, using an additive manufacturing process, building the metallic article from the powder-form metallic material, layer-by-layer, in a build direction, wherein as a result of the additive manufacturing process, the metallic article comprises columnar grain structures oriented in the build direction, and conveying the metallic article through a gradient furnace in a direction of conveyance from a first area of the gradient furnace to a second area of the gradient furnace to increase a size of the columnar grain structures in the metallic article. The metallic article is conveyed through the gradient furnace in an orientation such that the columnar structures oriented in the build direction are substantially parallel to the direction of conveyance.

Fire- and electromagnetic interference (EMI)-resistant aircraft components and methods for manufacturing the same are provided. A thermally and electrically conductive coating material layer is formed on at least a portion of an intermediate article comprised of a non-metallic material. The thermally and electrically conductive coating material layer is comprised of a metal. A fire-retardant material layer is cold sprayed on the thermally and electrically conductive coating material layer. At least one continuous electrically conductive element may be integrated with the non-metallic material of the intermediate article.

A coupling apparatus for use in sealingly connecting a first fluid flow path to a second fluid flow path. The coupling apparatus includes a rigid fluid flow channel having a first end and a second end, wherein the fluid flow channel is substantially rigid in an axial direction and a radial direction, a first sealing terminus that is rigidly connected to the first end and that is configured for sealing with the first fluid flow path, and a second sealing terminus that is slidingly disposed about the second end such that the second sealing terminus is configured for relative movement with respect to the second end, and wherein the second sealing terminus is further configured for sealing with the second fluid flow path. The coupling apparatus further includes a flexible coupler connected to both the first sealing terminus and the second sealing terminus and surrounding the fluid flow channel, wherein the coupler is relatively more flexible in the axial direction and the radial direction as compared to the fluid flow channel.

A sealing system includes two fittings, a compliant member, and a spring. The first fitting has two ends, a first cavity, and a first channel. The first channel extends from the first end to the first cavity, which is formed in the second end radially inwardly from an outer surface of the first fitting. The second fitting is disposed in the first cavity and has two ends, a second cavity, and a second channel. The first end is disposed in the first cavity, the second cavity is formed in the first end of the second fitting, and the second channel extends from the second cavity to the second end. The compliant member is disposed in the second cavity. The spring is disposed in the second cavity against the compliant member.
