摘要： A combustion nozzle (2) discharges compressed air (PA) and fuel (F), to be combusted, into a combustion chamber (3) of a combustor (1) of a gas turbine. The combustion nozzle (2) includes an air inlet (4a), a nozzle orifice (2d), an air channel (2x), a fuel channel (2ϕ), and fuel outlets (2f). The air inlet (4a) receives the compressed air (PA). The nozzle orifice (2d) opens into the combustion chamber (3) and discharges the compressed air (PA). The air channel (2x) communicates between the air inlet (4a) and the nozzle orifice (2d). The fuel channel (2ϕ) receives the fuel (F), and discharges the fuel (F) from the fuel outlets (2f) toward a flow of the compressed air (PA) discharged from the nozzle orifice (2d). The air channel (2x) includes a Venturi section (2e) in which a channel cross-sectional area of the compressed air (PA) becomes relatively small. The fuel outlets (2f) are provided in the Venturi section (2e).

摘要： An assembly is provided for a gas turbine engine (20). This engine assembly includes a fuel injector assembly (62), and the fuel injector assembly (62) includes a fuel swirler (122) and an air swirler (88). The fuel swirler (122) is configured to swirl fuel in a direction about the axis (72) to provide swirled fuel. The fuel injector assembly (62) is configured to inject the swirled fuel as an annular fuel flow along an axis (72). The air swirler (88) is configured to swirl air in the direction about the axis (72) to provide swirled air. The fuel injector assembly (62) is configured to inject the swirled air as an annular air flow along the axis (72), adjacent and circumscribing the annular fuel flow.

摘要： A method (1100) for manufacturing a fuel spray nozzle (200, 1000) for a gas turbine engine (10) includes forming a first section (230, 1002) of the fuel spray nozzle (200, 1000) by additive layer manufacturing. The first section (230, 1002) includes a main chamber (206) and internal passageways (208, 1006). The method (1100) includes forming a second section (230, 1004) of the fuel spray nozzle (200, 1000) by additive layer manufacturing on the first section (230, 1002). The second section (230, 1004) includes a metering feature (242, 1008) disposed in fluid communication with one of the internal passageways (208, 1006) of the first section (230, 1002). The method (1100) includes modifying the metering feature (242, 1008) of the second section (230, 1004) by a first subtractive manufacturing process to obtain a desired diameter (D2) of the metering feature (242, 1008) and/or a desired surface roughness of the metering feature (242, 1008). The method (1100) includes forming a third section (250) of the fuel spray nozzle (200, 1000) by additive layer manufacturing on the second section (230, 1004). The third section (250) includes a deflector (220) and a spin chamber (222).
