Abstract: A fluid dispensing apparatus that may be additive manufactured as one unitary piece and may be a fuel injector for a gas turbine engine includes a radial displacement bellows having an outer surface that faces and may be exposed to a surrounding environment and an interior surface that faces and may define at least in-part a flowpath extending along a centerline. The radial displacement bellows is constructed and arranged to move between an expanded state when a pressure differential between the environment and the flowpath is low to a restricted state when the pressure differential is high.

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.

Abstract: A method of monitoring the residual stress in surface and near surface regions of a component includes identifying predetermined locations on the surface of a component that are expected to experience high stress during normal operating conditions of the component. Marker particles are introduced into the component during additive manufacture of the component at the predetermined locations. Then, the residual stress of the component is measured at a location corresponding with the marker material using x-ray techniques.

Abstract: A machine for fabricating a fiber-reinforced component by additive manufacturing is disclosed. The machine may have a surface, a matrix feed configured to deposit a plurality of matrix layers on the surface, and a fiber feed configured to deposit a fiber layer on at least one of the plurality of matrix layers. The deposition of the plurality of matrix layers and the fiber layer may be controlled by a computer.

Abstract: A structure includes a first body section that has a wall that spans in a vertical direction. The wall has a relatively thin thickness with respect to a length and a width of the wall. A second body section is arranged next to, but spaced apart from, the first body section. A gusset connects the first body section and the second body section. The gusset extends obliquely from the wall of the first body section with respect to the vertical direction such that the gusset is self-supporting. The first body section has a geometry that corresponds to an end-use component exclusive of the gusset.
