Turbine engine fuel injector assembly with annular fuel outlet

An apparatus for a turbine engine, comprising:

• a fuel injector nozzle extending axially along an axis to a nozzle tip, the fuel injector nozzle including an inner fuel passage, an outer fuel passage, an inner divergent surface and an outer divergent surface;
• the inner fuel passage extending axially within the fuel injector nozzle to an inner passage outlet, the inner divergent surface forming a divergent portion of the inner passage outlet at the nozzle tip, a downstream end of the inner divergent surface axially upstream of and contacting an upstream end of the outer divergent surface along the axis, and the inner divergent surface angularly offset from the axis between thirty-five degrees and forty-five degrees;
• a center body disposed within the inner fuel passage axially proximate the nozzle tip, the center body extending axially within the inner fuel passage from a center body upstream end to a center body downstream end, and the center body extending radially within the inner fuel passage to a center body outer side;
• and
• the outer fuel passage extending axially within the fuel injector nozzle to an annular outer passage outlet, and the outer divergent surface forming a divergent portion of the annular outer passage outlet at the nozzle tip;
• wherein the annular outer passage outlet extends through the outer divergent surface.

An apparatus for a turbine engine, comprising:

• a swirler assembly;
• a fuel injector nozzle projecting axially along an axis into a bore of the swirler assembly, the fuel injector nozzle including an inner fuel passage, an outer fuel passage, an inner divergent surface and an outer divergent surface;
• the inner fuel passage extending axially within the fuel injector nozzle to an inner passage outlet, a downstream portion of the inner fuel passage including an inner convergent surface extending circumferentially about a center body disposed within the inner fuel passage, the inner fuel passage circumscribing the center body, and the inner divergent surface forming a divergent portion of the inner passage outlet;
• the outer fuel passage extending axially within the fuel injector nozzle to an annular outer passage outlet, and the outer divergent surface forming a divergent portion of the annular outer passage outlet;
• and
• the inner divergent surface extending axially along the axis to the outer divergent surface, and the outer divergent surface projecting axially out from the inner divergent surface;
• and
• a nozzle guide mounting the fuel injector nozzle to the swirler assembly, the nozzle guide axially moveable along and radially engaged with an exterior surface of the fuel injector nozzle;
• wherein the annular outer passage outlet extends through the outer divergent surface.
