Zusammenfassung:	A combustor dome assembly includes a dome plate (34) with upstream and downstream faces (31,33) and an aperture (36) therein; a deflector (38) with body (42) and a tube section (54), the deflector fixedly attached to the dome plate adjacent the downstream face with the tube section (54) in the aperture (36); a retainer (39) having an annular body with a central opening therein, an annular flange, and at least one hook (72) defining a slot, the retainer (39) being fixedly attached to the dome plate (34) adjacent the upstream face of the dome plate with the flange received in the aperture; and an annular mixer (40) with a radial array of swirl vanes (86) and an annular mounting flange (88), with a retention tab (94) extending radially outward from the mounting flange. The mixer is disposed adjacent the upstream face with the mounting flange against the retainer. The retention tab is engaged in the slot defined by the hook to prevent axial withdrawal of the mixer from the retainer.
