| 摘要 |
The invention relates to an swirler vane (10a) for providing fuel, particularly liquid fuel, to a swirling zone (3) of a burner assembly, comprising at least one injection hole (11) for injecting the fuel to the swirling zone (3) of the burner (1) and an injection feed hole passage (12) connecting the at least one injection hole (11) with a main fuel feed (4), which is characterized in that the swirler vane (10a) or a tip (20a) of the swirler vane (10a), where the at least one injection hole (11) is arranged, is being manufactured by pulsed laser physical vacuum deposition or comprises at least a surface being manufactured by pulsed laser vacuum deposition. The invention relates further to a swirler (2), comprising a plurality of such swirler vanes (10) and to a burner assembly, in particular of a gas turbine engine, comprising a swirler (2) with such swirler vanes.
