Abstract: A heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a plurality of fluid passageways that are formed by additive manufacturing methods which enable the formation of fluid passageways that are smaller in size, that have thinner walls, and that have complex and intricate heat exchanger features that were not possible using prior manufacturing methods. For example, the fluid passageways may be curvilinear and may include heat exchanging fins that are less than 0.01 inches thick and formed at a fin density of more than four heat exchanging fins per centimeter. In addition, the heat exchanging fins may be angled with respect to the walls of the fluid passageways and adjacent fins may be offset relative to each other.

Abstract: A method and system for an air management system (AMS) is provided. The AMS includes a jet pump assembly including a motive air inlet, a plurality of suction inlets, and a single outlet. The AMS also includes a supply piping arrangement including a conduit configured to channel relatively higher pressure air from a compressor to the motive air inlet, a conduit configured to channel relatively higher pressure air from the compressor to at least one of the plurality of suction inlets through a shutoff valve, and a conduit configured to channel relatively lower pressure air from the compressor to at least one of the plurality of suction inlets. The AMS further includes an outlet piping arrangement configured to channel outlet air from said jet pump assembly to a distribution system. A pressure regulation strategy of the motive jet pump flow allows optimization of engine fuel burn and/or thrust, depending on which is most important to the aircraft during any flight phase.

Abstract: A method and system for a jet pump is provided. The jet pump system includes a pre-mixing bowl includes a nozzle, a mixing section at least partially surrounding the nozzle, and a first inlet opening configured to receive a first flow of fluid and direct the first flow of fluid to an inlet of the nozzle. The pre-mixing bowl further includes a second inlet opening configured to receive a second flow of fluid and to direct the second flow of fluid to the mixing section. The second inlet opening includes a first inlet opening area. The second inlet opening includes an entry angle into the pre-mixing bowl that is oblique with respect to the central axis. The pre-mixing bowl further includes a third inlet opening configured to receive a third flow of fluid to direct the third flow of fluid to the mixing section.
