Abstract:
A heat exchanger includes a separator member that divides a first flow passage from a second flow passage. The heat exchanger also includes a plurality of first hollow members that extend across the first flow passage at respective non-orthogonal angles. The plurality of first hollow members are fluidly connected to the second flow passage. Moreover, the heat exchanger includes a plurality of second hollow members that extend across the second flow passage at respective non-orthogonal angles. The plurality of second hollow members are fluidly connected to the first flow passage.
Abstract:
An enhanced acoustic cell for use in acoustic panels is provided. The provided enhanced acoustic cell has a parabolic-shaped cell floor and a receiving object suspended at its focal point. Components of the enhanced acoustic cell may be easily replicated and installed into a face sheet comprising an array of a plurality of interconnected acoustic cells.

Abstract:
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.
Abstract:
A heat exchanger may include at least one fluid passageway adjacent a heat transfer plate and a plurality of heat transfer elements positioned in the at least one fluid passageway and joined with the heat transfer plate. The heat transfer elements may be positioned with first spacings therebetween at an inlet end of the at least one fluid passageway. The heat transfer elements may be positioned with second spacings therebetween at an outlet end of the at least one fluid passageway. The first spacings may be smaller than the second spacings.

Abstract:
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.
Abstract:
Thermal isolating service tubes and assemblies thereof for gas turbine engines are provided. The thermal isolating service tube comprises an inner tubular member defining a fluid passage and at least one outer tubular member disposed about the inner tubular member. A spacing volume is defined between at least the inner tubular member and an adjacent outer tubular member. The thermal isolating service tube comprises a unitary structure and has at least one portion with a curved configuration, a non-circular cross-sectional shape, or both.
