ABSTRACT:
A gas turbine combustor (10) comprises a main swirler assembly (400) comprising an annulus casting (410) itself comprising a modified downstream end (418) fitted into an reversed-edge base plate (450) that comprises an opening (453) defined by a lip (452) oriented upstream. The lip (452) comprises an upstream surface (457), an outboard surface (458) and an inboard surface (459). In certain embodiments the modified downstream end (418) has a shape to fit against the upstream surface (457) and the outboard surface (458) so as to increase the natural frequency of the main swirler assembly (400) to above the natural frequency of the combustion in the gas turbine combustor (10).
