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: An injection system includes an inner nozzle body defining a first air path along a longitudinal axis. The first air path defines a converging-diverging section between an upstream portion of the first air path and an outlet orifice of the first air path. A main orifice is defined at a narrowest portion of the converging-diverging section. A fuel circuit wall is outboard of the inner nozzle body. A fuel path is defined between the fuel circuit wall and the inner nozzle body. An outer nozzle body outboard of the fuel circuit wall has a second air path defined through the inner nozzle body for communication of air from the outer nozzle body into the first air path, wherein the second air path meets the first air path at a second orifice in the first air path downstream of the main orifice of the inner nozzle body.

Abstract: A nozzle includes a nozzle body defining a liquid circuit extending from a liquid inlet to a liquid outlet. The liquid circuit includes a plurality of spiral liquid passages spiraling radially inward relative to a spray axis. The spiral liquid passages all lie in a plane normal to the spray axis. A manifold assembly includes a plurality of such nozzles. A manifold ring is in fluid communication with the liquid inlet of each of the nozzles to deliver liquid to the nozzles. The nozzles are circumferentially spaced apart around the manifold ring.

Abstract: A system includes an air manifold, a fuel manifold, and a plurality of fuel injectors. At least one of the fuel injectors includes a heat exchanger portion for supplying compressed, cooled air form the heat exchanger portion to the air manifold. An air valve is operatively connected to an outlet of the air manifold for controlling release of air from the air manifold. A controller is operatively connected to the air valve, wherein the controller includes machine readable instructions configured to control the air valve to regulate flow of air through the air valve based on fuel temperatures in the fuel channel. The machine readable instructions can be configured to cause the controller to flow air through the air valve in a heat exchange mode if a fuel temperature in the fuel injectors is below a predetermined fuel temperature.

Abstract: In accordance with at least one aspect of this disclosure, a nozzle for a fuel injector includes, a nozzle body defining a central axis from a nozzle inlet to a nozzle outlet. A first fuel circuit is defined in the nozzle body configured to issue a first fuel flow from a first outlet orifice into a combustor. A second fuel circuit is defined in the nozzle body radially outward from the first fuel circuit configured to issue a second fuel flow from a second outlet orifice at a prefilmer surface of the nozzle body. A third fuel circuit is defined in the nozzle body radially outward from the second fuel circuit configured to issue a third fuel flow from a third outlet orifice at the prefilmer surface of the nozzle body. In embodiments, the first fuel circuit, the second fuel circuit, and the third fuel circuit can all be fluidly isolated from one another within the nozzle body.
