Abstract: An internal fuel manifold for a turbomachine can include an outer ring defining one or more fuel supply channels configured to allow fuel flow around at least a portion of a circumference of the outer ring, and a plurality of branches extending radially inward from the outer ring. The branches include a high aspect ratio shape. The plurality of branches can include one or more branch fuel channels in fluid communication with at least one of the one or more fuel supply channels. The manifold includes one or more injector connectors extending axially aft from each branch, each injector connector in fluid communication with a branch fuel channel and configured to connect to a fuel injector. The manifold can include an inner ring extending from the plurality of branches. The inner ring and the outer ring are configured to receive a fuel injector and combustor assembly therebetween and to allow retaining of the fuel injector assembly and combustor assembly to the internal fuel manifold.

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: An injector for a multipoint combustor system includes an inner air swirler which defines an interior flow passage and a plurality of swirler inlet ports in an upstream portion thereof. The inlet ports are configured and adapted to impart swirl on flow in the interior flow passage. An outer air cap is mounted outboard of the inner swirler. A fuel passage is defined between the inner air swirler and the outer air cap, and includes a discharge outlet between downstream portions of the inner air swirler and the outer air cap for issuing fuel for combustion. The outer air cap defines an outer air circuit configured for substantially unswirled injection of compressor discharge air outboard of the interior flow passage.

Abstract: A fuel injector for a gas turbine engine includes a feed arm defining a conduit extending between an inlet end and an outlet end and a plunger. The plunger is disposed within the conduit and is movable between a plunger first position and a plunger second position. A flow area defined between the plunger and the feed arm is smaller in the plunger first position than in the plunger second position to bias fuel flow through the fuel injector. Fuel systems, gas turbine engines, and methods of controlling fuel flow in gas turbine engine fuel systems are also described.

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 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 multipoint fuel injection system includes a plurality of fuel manifolds. Each manifold is in fluid communication with a plurality of injectors arranged circumferentially about a longitudinal axis for multipoint fuel injection. The injectors of separate respective manifolds are spaced radially apart from one another for separate radial staging of fuel flow to each respective manifold.
