Abstract
A swirler for a gas turbine engine fuel injector comprises a swirler body extending from an upstream end to a downstream end. A fuel injector extends into the body, and has a downstream end for injecting fuel in a downstream direction. A first flow path directs air in a first circumferential direction about a central axis of the swirler body. A second flow path directs air to intermix with the air in the first flow path, and then to mix with fuel injected by the fuel injector. The first and second flow paths are positioned to inject air upstream of the downstream end of the fuel injector where fuel is injected. The first flow path is provided in a greater volume than the volume provided in the second flow path. The second flow path directs air at a location downstream of the first flow path.
