Abstract
A combustor dome assembly is provided with a single continuous annular dome plate having at least one circumferential row of spaced openings therethrough, a swirl cup assembly attached to each of the dome plate openings, and inner and outer cowls connected to the radially inner and outer ends of the dome plate. A ferrule located immediately upstream of the swirl cup assembly acts as an interface between a fuel nozzle and the swirl cup assembly. An integral cowl plate/ferrule retainer is located immediately upstream of and connected to the swirl cup assembly, where the ferrule retainer portion retains the ferrule while allowing it to float radially therewithin and the cowl plate portion includes flanges which extend beyond the outer diameter of the swirl cup to provide blockage in addition to that provided by the inner and outer cowls.
