Abstract: A transfer tube assembly includes an outer tube defining a first flow path and an inner tube positioned within the first flow path. The inner tube defines a second flow path in fluid isolation from the first flow path. A connecting segment is downstream from the inner tube and the outer tube. The connecting segment has a first bore in fluid communication with the first flow path and a second bore in fluid communication with the second flow path.

Abstract: A method of joining includes applying braze to a braze reservoir in a first component. A second component is engaged to the first component, wherein a joint location is defined between the first and second components. A wicking structure provides flow communication from the braze reservoir to the joint location. The method also includes joining the first and second components together at the joint location by applying heat to the braze to flow the braze from the reservoir through the wicking structure to the joint location to form a braze joint at the joint location.

Abstract: An injector includes a fuel distributor with a first fluid inlet and a first fluid outlet, with a first fluid circuit for fluid communication between the first fluid inlet and the first fluid outlet. The fuel distributor includes a second fluid inlet and a second fluid outlet, with a second fluid circuit for fluid communication between the second fluid inlet and outlet. The fuel distributor defines a spray axis. The first and second fluid outlets can be radially adjacent and/or can be substantially aligned axially relative to the spray axis, e.g., for issuing multiple different fuels from substantially the same outlet.

Abstract: A nozzle includes a nozzle body defining a longitudinal axis and including a primary distributor and a secondary distributor. The primary distributor has an inner air passage fed by a radial swirler; a first fuel circuit radially outboard from the inner air passage with respect to the longitudinal axis; a second fuel circuit radially outboard from the first fuel circuit with respect to the longitudinal axis, wherein each of the first fuel circuit and the second fuel circuit extends from a respective fuel circuit inlet to a respective annular fuel circuit outlet; and an outer air passage defined between a fuel circuit outer wall and an outer air passage wall, wherein the outer air passage is a converging non-swirling outer air passage. The secondary distributor similar to the primary distributor is downstream of the primary distributor with respect to the longitudinal axis.

Abstract: A method of issuing a spray cone from a nozzle includes modulating flow to two separate first and second fluid circuits, each connected to a common injection point orifice to vary spray angle on a substantially hollow spray cone over time to create a full spray cone. Modulating can include controlling first and second flow modulators, connected to the first and second fluid circuits, respectively, to coordinate oscillating flow rate modulation of both of the first and second fluid circuits. Controlling can include controlling the oscillating flow rate modulation for the first flow modulator to be out of phase with, to be in antiphase with, to be vertically shifted in magnitude relative to, and/or to have an amplitude that is equal to that of the second flow modulator.

Abstract: A nozzle includes a nozzle body defining longitudinal axis with a liquid circuit extending axially in a downstream direction from a liquid inlet to a spray orifice, and an air circuit, e.g. an inner air circuit, extending axially downstream from an upstream air inlet to an air outlet proximate the spray orifice. An air swirler, e.g., an inner air swirler is mounted in the air circuit, wherein at least a portion of the air swirler is flush with or protrudes axially upstream relative to the air inlet.

Abstract: A method of manufacturing includes depositing a braze filler adjacent to a void between a first component and a second component thus holding the components in position before brazing. The first and second components are heated to melt and flow the braze filler into the void. A braze joint is formed between the first and second components by cooling the braze filler. Depositing the braze filler can include laser cladding the braze filler to the first and/or second components adjacent the void. The method also optionally includes welding the first and second components in position with the braze filler adjacent to the void. The braze filler may be deposited as a powder, cold spray, melted brazed filament, spherical ball or any other suitable form.
