Disclosed is an axial swirler (14b) for a gas turbine burner including a vane ring with a plurality of swirler vanes (19b) circumferentially distributed around a swirler axis (11); and each said swirler vane (19b) having a trailing edge (22). In order to achieve a controlled distribution of a discharge flow velocity profile and/or a fuel equivalence ratio in a radial direction, said trailing edge (22) is discontinuous and has a discontinuity at a predetermined radius.;COPYRIGHT KIPO 2014
