Abstract:
A combustor (16) for a gas turbine engine includes a combustion chamber (54) having a centerline axis (110) extending therethrough, an outer support (42), an inner support (46), and a dome assembly (48). The dome assembly includes a domeplate (72) that extends between the inner and outer supports, and couples an inner and an outer support to the dome assembly. The domeplate includes at least one cooling slot lip (202) and at least one filler projection (206), wherein the at least one cooling slot is spaced radially from the at least one filler projection such that a gap (210) is defined therebetween.
