  • Patent number: 10508759
    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.

  • Patent number: 10486271
    Abstract: A welding apparatus having a welding tool and a weld cooling apparatus for forced cooling of the weld zone. The welding tool has a welding nozzle with a longitudinal axis, and the weld cooling apparatus uses a source of CO2 as the coolant. A coolant delivery conduit is arranged to move with the welding tool and has a first tube with a longitudinal axis that extends alongside the welding tool, and a second tube with a longitudinal axis extending downwardly and away from the welding tool. A coolant nozzle is located at the end of the second tube to eject coolant at the weld zone. The coolant nozzle outlet is spaced from the workpiece and arranged to direct a jet of coolant behind the welding tool onto the weld zone at least 10 mm from the longitudinal axis of the first tube.

  • Patent number: 10480868
    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 thermal stresses thereby further minimizing thermal conduction between tubes.

  • Patent number: 10208673
    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.
