Abstract: A method for assembling a fuel distribution system for a turbomachine fuel injector includes inserting a liquid fuel distributor into an interior cavity of a shroud to create a liquid fuel distribution circuit between the liquid fuel distributor and the shroud and inserting a gas fuel distributor into the interior cavity of the shroud and into an interior cavity of the liquid fuel distributor to create a gas fuel distribution circuit between the gas fuel distributor and the liquid fuel distributor. The method includes inserting a fuel transfer tube into an outer diameter of the shroud. The method includes brazing or shrink fitting at least one of the fuel transfer tube, the gas fuel distributor, or the liquid fuel distributor to the shroud.

Abstract: A combustor dome system includes an annular combustor dome defining a main axis therethrough. The combustor dome includes opposed upstream and downstream faces, wherein the upstream face is configured to face upstream toward a compressor discharge space, wherein the downstream face is configured to face downstream toward a combustor space. The downstream face has a curved cross-sectional profile. A plurality of nozzles extends at least partially through the combustor dome from the upstream face to the downstream face for injection of fuel into the combustor space. A fuel manifold is in fluid communication with the plurality of nozzles.

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 combustor for a gas turbine engine includes an inner combustor wall and an outer combustor wall radially outboard of the inner combustor wall. The inner and outer combustor walls define a combustion space therebetween with an upstream inlet and a downstream outlet. A combustor dome connects between inner and outer combustor walls at the upstream inlet of the combustion space. The combustor dome includes a plurality of circumferentially spaced apart nozzles and a plurality of tiles mounted to the combustor dome to fluidly separate a downstream side of the combustor dome from an upstream side of the combustor dome.

Abstract: A swirl element for swirling fluid in a nozzle has a swirler body. The swirler body defines a feed channel including an axially oriented channel surface and a swirl chamber in fluid communication with the feed channel. The swirl chamber defines a radially oriented swirler surface substantially normal to the channel surface. The swirl chamber and the axially oriented channel are in fluid communication through a tangential slot for imparting swirl on fluids passing from the feed channel into the swirl chamber. The tangential slot includes a smoothly rounded surface transitioning from the channel surface to the swirler surface for providing a smooth, substantially separation free transition in fluid flow from the channel into the swirl chamber.

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.
