A fuel injector comprises a plurality of swirler vane passages defined between swirler vanes. Each vane is leant with respect to the true radius of the swirler. The pressure distribution through the swirler passages is improved and the flow of air over a prefilmer located at the radially outer edges of the swirl vanes is improved and consequently atomization of fuel is improved and levels of NOx is reduced. |
