Abstract
A swirler is provided for mixing air from a compressor and fuel from a fuel injector for discharge into a dome of a gas turbine engine combustor. The swirler includes a tubular ferrule for coaxially receiving the fuel injector. A plurality of circumferentially spaced apart swirl vanes are fixedly joined coaxially with the ferrule. An outlet tube is fixedly joined coaxially with the swirl vanes in flow communication therewith for receiving air from the swirlers and fuel from the fuel injector. An annular collar is fixedly joined around the outlet tube and has a convex spherical outer surface. An annular mounting flange for mounting the swirler to the combustor dome has a concave spherical inner surface disposed coaxially around the collar outer surface in a sliding fit therewith to define a ball joint for allowing relative rotation therebetween for self-aligning the fuel injector with the swirler.
