ABSTRACT:
A gas turbine engine combustor is provided with a combustor dome plate film cooling means having an annular slotted ring to provide a film starting means upstream of a multi-hole film cooled single wall metal dome plate which is annular in shape. One particular embodiment provides a starting slot in the form of a plurality of rings surrounding the edges of the air/fuel nozzle inlet apertures in the dome plate. The cooling holes are disposed in concentric circles about the apertures and angled along radii emanating from the center of the apertures. This produces a cooling film emanating radially from the ring like circular slots around each air/fuel nozzle inlet aperture in the dome plate. Another embodiment provides a starting slot in the form of circumferential rails circumferentially disposed about the inner and outer circumferential edges of dome plate. The cooling holes are arranged in two section, the first to feed a radially inward directed cooling film that is initiated from an outer starting slot on a radially outer circumferential edge of the plate. The second sections has film cooling holes angled radially outward to feed a radially outward directed cooling film emanating an inner starting slot on a radially inward circumferential edge of the plate.
