Zusammenfassung:	PREMIXED FUEL NOZZLE A fuel injector assembly (70) for a gas turbine engine (10) is generally provided. The first fuel injector (100) includes a first centerbody (110) surrounding a first walled fuel injection circuit (120). A first fuel injection port (130) is extended at least partially radially through the first centerbody (110) in fluid communication with the first walled fuel injection circuit (120). The first centerbody (110) defines a cooling circuit (140) surrounding the first walled fuel injection circuit (120). The first centerbody (110) defines a plurality of cooling openings (115) at a downstream end (98) of the first centerbody (110). The plurality of cooling openings (115) is in fluid communication with the cooling circuit (140). The first centerbody (110) defines an axially extended cooling outlet at the downstream end (98) of the first centerbody (110).
