Abstract:
A damper-seal assembly for a gas turbine engine includes an additively manufactured seal and an additively manufactured damper inseparably assembled with the additively manufactured seal.
Abstract:
A fuel/oil manifold includes first and second manifold flanges and a manifold tube. The first and second manifold flanges are located in non-parallel planes with respect to one another. The manifold tube is connected at a first end to the first manifold flange and at a second end to the second manifold flange and includes at least one turn between the first and the second end that includes a non-zero tube bend radius defined as the ratio of a turn radius to a diameter of the manifold tube.
Abstract:
A heat exchanger assembly for a gas turbine engine including a frame, including a non-planar outer wall, a non-planar inner wall spaced radially inward from the non-planar outer wall to form a frame cavity therebetween, an inlet side extending between the non-planar outer wall and the non-planar inner wall, an inlet passage extending through the inlet side, an outlet side extending between the non-planar outer wall and the non-planar inner wall opposite the inlet side; an outlet passage extending through the outlet side, and a continuous non-planar core disposed within the frame cavity and in flow communication with the inlet passage and the outlet passage.
Abstract:
A process is provided involving an agitator. This process includes steps of: (a) disposing an object with the agitator, which object includes an aperture therein; (b) disposing abrasive material within the aperture; and (c) agitating the abrasive material by moving the object using the agitator.
Abstract:
A component includes an additively manufactured component with an internal passage and an additively manufactured elongated member within the internal passage. A method of additively manufacturing a component including additively manufacturing a component with an internal passage; and additively manufacturing an elongated member within the internal passage concurrent with additively manufacturing the component.
Abstract:

Abstract:
A septum-tied tube pack is provided that includes a first outer wall formed by a multiple of first connected radiuses. A second outer wall is formed by a multiple of second connected radiuses. A first end radius connects the first outer wall and the second outer wall. A second end radius connects the first outer wall and the second outer wall. A multiple of septum elements extend between the first outer wall and the second outer wall. A gas turbine engine is also provided that includes an engine case structure and a fluid conduit mounted to the engine case structure. The fluid conduit includes a septum-tied tube pack section.
Abstract:
A duct includes an upstream segment and a downstream segment mounted to the upstream segment. A heat shield extends from one of the upstream and downstream segments. A sealing land extends from the other of the upstream and downstream segments, and is configured to engage with the heat shield. The heat shield protects the interface between the upstream and downstream segments of the ducts.
Abstract:
Components may be manufactured by co-extruding a polymer filament and a fiber filament from a nozzle. The polymer filament and the fiber filament may be heated within the nozzle, which may couple the polymer filament to the fiber filament. The co-extruded filament may result in long reinforcing fibers which provide strength to the components.
