Zusammenfassung:	PURPOSE: To provide a combustor dome for a gas-turbine engine combustor, which has cooling air apertures and can be easily manufactured without the need for complicated machining. CONSTITUTION: An annular dome plate 24 included in a combustor dome 22 has a plurality of circumferentially spaced apertures in a central portion thereof for receiving a plurality of carburetors 28 therein. The dome plate also includes outer and inner support portions for joining the dome plate to combustion liners 16 and 18. Each of the support portions includes a first leg extending from the central portion of the dome plate, a second leg, and an arcuate apex joining the first and second legs. The apex has a uniform thickness and includes a plurality of circumferentially spaced coolant apertures for channeling cooling air therethrough.
