Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a combustor dome assembly that is simple to assemble, which reliably retains a mixer and a deflector.SOLUTION: The combustor dome assembly 32 includes: a dome plate 34; a deflector 38 with a body and a tube section, the deflector fixedly attached to the dome plate adjacent the downstream face with the tube section in the aperture; a retainer 39 having an annular body with a central opening therein, an annular flange, and at least one hook defining a slot, the retainer being fixedly attached to the dome plate adjacent the upstream face of the dome plate with the flange received in the aperture; and an annular mixer with a radial array of swirl vanes and an annular mounting flange. The mixer is disposed adjacent the upstream face with the mounting flange against the retainer. A retention tab is engaged in the slot to prevent axial withdrawal of the mixer from the retainer.
