FUEL INJECTOR ASSEMBLY FOR GAS TURBINE ENGINE

FUEL INJECTOR ASSEMBLY FOR GAS TURBINE ENGINE

A turbine engine assembly includes a fuel injector assembly (62) having an inner air swirler (124) and a fuel swirler (126). The inner air swirler (124) is configured to swirl inner air in a direction about an axis (72) to provide inner swirled air. The fuel injector assembly (62) is configured to i...

Zusammenfassung:A turbine engine assembly includes a fuel injector assembly (62) having an inner air swirler (124) and a fuel swirler (126). The inner air swirler (124) is configured to swirl inner air in a direction about an axis (72) to provide inner swirled air. The fuel injector assembly (62) is configured to inject the inner swirled air as an inner air flow along an inner air flow trajectory (172) parallel with the axis (72). The fuel swirler (126) is configured to swirl fuel in the 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 a fuel flow trajectory (174) parallel with the axis (72). The annular fuel flow is adjacent and circumscribes the inner air flow.
