Abstract: A tube assembly (20) is additive manufactured as one unitary piece and has a first tube (56) that co-extends with and is surrounded by a second tube (58). An annular void (60) may be defined by and located between the first and second tubes (56, 58) for insulating a fluid flowing through the first tube (56). The void (60) may be sealed and under a negative atmospheric pressure for enhancing insulating properties.

Abstract: A tube assembly that may be for a fuel nozzle (20) of a fuel system of a gas turbine engine may have a first tube (56) defining a first flowpath (59) along a centerline (52), a second tube (58) generally spaced radially outward from the first tube (56) with a first void (60) located between and defined by the first and second tubes (56, 58), and a support structure (68) located in the first void (60) and extending between the first and second tubes (56, 58). The support structure (68) is constructed and arranged to minimize or eliminate thermal conduction between the tubes (56, 58). 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 (68) due to thermal stresses thereby further minimizing thermal conduction between tubes (56, 58).

Abstract: One embodiment includes a fuel injector. The fuel injector assembly comprises a conduit for conveying fuel from a fuel inlet to a nozzle. The conduit is located in a support, with the conduit, the nozzle, and the support being a single unitary piece. A thermally compliant feature is located at the nozzle which allows the fuel injector to adjust for differential thermal expansion.

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 flowpath assembly (20) has a first conduit (56) defining a flowpath radially inward, and a second conduit (58) spaced radially outward from the first conduit (56). A void (60) defined between the first and second conduits (56, 58) contains an insulating material (61) that may have a greater porosity than the first and second conduits (56, 58). The assembly (20) may be additive manufactured generally as one unitary piece with the raw material of the conduits (56, 58) being melted and solidified on a slice-by-slice basis and the insulating material (61) being selectively bypassed by an energy gun (108) of an additive manufacturing system (100).
