Abstract: A fuel injector for a turbomachine includes an inner heat shield having an air cavity wall defining an air cavity for allowing air to flow therethrough. The inner heat shield includes an integral air swirler forming a downstream end thereof. The integral air swirler extends in an axially downstream direction at least as far as a fuel distribution channel defined on or in a fuel distributor of the injector to direct airflow at an outlet of the fuel distributor.

Abstract: A fuel distributor system for a turbomachine fuel injector can include a plurality of helical fuel flow channels defined between a fuel distributor and a shroud that surrounds the fuel distributor. A wind axis of the helical flow channels is an axial axis of the fuel injector and each of the helical fuel flow channels include an upstream opening configured to be in fluid communication with a liquid fuel source and a downstream opening configured to effuse fuel therefrom. Each of the plurality of helical fuel flow channels can reduce in flow area from the upstream opening to the downstream opening.

Abstract: A fuel conduit for a fuel injector includes a coiled tube with a longitudinal segment arranged along a flow axis and a radial segment. The radial segment extends about the flow axis and is in fluid communication with the longitudinal segment. The wall one or more of the longitudinal and radial segments increases at a thickness transition location offset from a minimum radius of curvature location along the fuel conduit to limit stress within the fuel conduit. Fuel injectors and methods of making fuel injectors are also described.

Abstract: A swirler, such as for swirling air in a fuel injector of a gas turbine engine, includes a swirler body with opposed inlet and outlet ends with a swirler wall extending therebetween along a longitudinal axis. The inlet end of the swirler body defines an inlet opening. A plurality of swirl slots is defined through a portion of the swirler wall that converges toward the longitudinal axis in a direction from the inlet opening toward the outlet end of the swirler body. The swirl slots are radially off-set with respect to the longitudinal axis for imparting swirl on a flow passing from the inlet opening, through the swirl slots, and past the outlet end of the swirler body.

Abstract: A system for inspecting spray nozzles includes a nozzle operatively connected to a source of pressurized liquid for issuing a spray from the nozzle. The system also includes a sensor positioned to detect frequencies of resonant modes in the spray. The nozzle and sensor can each be mounted to a spray test booth. A method of inspecting a spray nozzle includes issuing a liquid from a spray nozzle as a spray and using a sensor to detect frequencies of resonant modes in the spray. The sensor can include a diaphragm and detecting frequencies can include impinging at least some of the spray on the diaphragm, and monitoring vibrations of the diaphragm.

Abstract: A flow directing apparatus for directing fluid flow includes a flow body defining a bore therethrough configured and adapted to direct fluid flowing therethrough. The bore includes an outlet and an opposed inlet with an enlargement, formed as a countersink and/or a chamfer using a suitable boring device. The enlargement is configured and adapted to reduce sensitivity to entrance-edge conditions for the bore.

Abstract: An atomizer includes an atomizer body with a plurality of air passages defined therethrough from an upstream end of the atomizer body to a downstream end thereof. The air passages together define an air circuit through the atomizer body. A fuel circuit is defined in the atomizer body extending from a fuel inlet to a respective fuel outlet opening into each air passage. The air passages can be arranged circumferentially about a central axis defined by the atomizer body. The fuel circuit can include a manifold extending circumferentially about the atomizer body in fluid communication with a fuel opening in each respective air passage.

Abstract: A nozzle for injecting liquid includes a nozzle body defining a flow channel and a swirl ante-chamber in fluid communication with the flow channel. An injection point orifice is defined in the swirl ante-chamber. The flow channel feeds into the swirl ante-chamber to impart a tangential flow component on fluids entering the swirl ante-chamber to generate swirl on a spray issuing from the injection point orifice. A second flow channel can be included in fluid communication with the swirl ante-chamber. The second flow channel feeds into the swirl ante-chamber in cooperation with or in opposition to the first flow channel. The first flow channel, second flow channel, and swirl ante-chamber are configured and adapted to adjust spray angle of a spray issuing from the injection point orifice by varying flow apportionment among the first and second flow channels.

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.
