Abstract
An assembly is provided for a turbine engine. This turbine engine assembly includes a fuel injector assembly, and the fuel injector assembly includes an inner air swirler and a fuel swirler. The inner air swirler is configured to swirl inner air in a direction about an axis to provide inner swirled air. The fuel injector assembly is configured to inject the inner swirled air as an inner air flow along an inner air flow trajectory parallel with the axis. The fuel swirler is configured to swirl fuel in the direction about the axis to provide swirled fuel. The fuel injector assembly is configured to inject the swirled fuel as an annular fuel flow along a fuel flow trajectory parallel with the axis. The annular fuel flow is adjacent and circumscribes the inner air flow.
