  • Publication number: 20160003556
    Abstract: A tube assembly that may be for a fuel nozzle of a fuel system of a gas turbine engine may have a first tube defining a first flowpath along a centerline, a second tube generally spaced radially outward from the first tube with a first void located between and defined by the first and second tubes, and a support structure located in the first void and extending between the first and second tubes. The support structure is constructed and arranged to minimize or eliminate thermal conduction between the tubes. The entire assembly may be additive manufactured as one unitary piece. One example of a method of operation may include designed-for breakage of the structural support due to then al stresses thereby further minimizing thermal conduction between tubes.

  • Publication number: 20160003157
    Abstract: A tube assembly is additive manufactured as one unitary piece and has a first tube that co-extends with and is surrounded by a second tube. An annular void may be defined by and located between the first and second tubes for insulating a fluid flowing through the first tube. The void may be sealed and under a negative atmospheric pressure for enhancing insulating properties.

  • Publication number: 20160003380
    Abstract: A flowpath assembly has a first conduit defining a flowpath radially inward, and a second conduit spaced radially outward from the first conduit. A void defined between the first and second conduits contains an insulating material that may have a greater porosity than the first and second conduits. The assembly may be additive manufactured generally as one unitary piece with the raw material of the conduits being melted and solidified on a slice-by-slice basis and the insulating material being selectively bypassed by an energy gun of an additive manufacturing system.

  • Publication number: 20160003158
    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.

  • Publication number: 20150336233
    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.

  • Publication number: 20150323183
    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.

  • Publication number: 20150322806
    Abstract: A ceramic component retention system includes a metallic component, a ceramic component, and at least one spring element arranged between the metallic component and the ceramic component. The metallic component has a first coefficient of thermal expansion, and the ceramic component has a second coefficient of thermal expansion. The at least one spring element is configured to mechanically couple the ceramic component to the metallic component.

  • Publication number: 20150165666
    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.

  • Publication number: 20140186098
    Abstract: A powder-derived, non-finished work piece 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.
