Abstract
A combustor assembly for a gas turbine engine includes a dome and a deflector positioned adjacent to the dome. One or both of the dome and the deflector define an opening, a component axis extending through the opening, and a radial direction relative to the component axis. The combustor assembly also includes a retainer having an outer member contacting the dome, the deflector or both. The outer member of the retainer defines at least in part a retainer cavity inward of the outer member along the radial direction. The dome, the deflector, or both define a plurality of cooling holes for providing a cooling airflow from the retainer cavity to the opening.
Claims20
A combustor assembly for a gas turbine engine, the combustor assembly comprising:
- a dome comprising a perimeter flange, the perimeter flange having a forward end;
- a deflector positioned adjacent to the dome and also comprising a perimeter flange defining a forward end, one or both of the dome and the deflector defining an opening, a component axis extending through the opening, and a radial direction relative to the component axis;
- and
- a retainer comprising an outer member contacting the perimeter flange of the dome, the perimeter flange of the deflector or both, the outer member of the retainer defining at least in part a retainer cavity inward of the outer member along the radial direction;
- wherein the dome, the deflector, or both define a plurality of cooling holes for providing a cooling airflow from the retainer cavity to the opening;
- wherein the plurality of cooling holes each extend between an inlet defined in the forward end of the perimeter flange of the dome, in the forward end of the perimeter flange of the deflector, or in both, and an outlet at the opening;
- wherein the perimeter flange of the dome contacts the perimeter flange of the deflector at a surface, and at least one of the plurality of cooling holes extends through the surface.
A combustor assembly for a gas turbine engine, the combustor assembly comprising:
- a dome comprising a perimeter flange, the perimeter flange having a forward end;
- a deflector attached to the dome and defining an opening and also comprising a perimeter flange defining a forward end, a component axis extending through the opening, and a radial direction relative to the component axis;
- and
- a retainer comprising an inner member and an outer member along the radial direction of the deflector, the inner member contacting the dome, the deflector or both, and the outer member contacting the perimeter flange of the dome, the perimeter flange of the deflector, or both, the retainer defining a retainer cavity between the inner member and outer member;
- wherein the dome, the deflector, or both define a plurality of cooling holes for providing a cooling airflow from the retainer cavity to the opening;
- wherein the plurality of cooling holes each extend between an inlet defined in the forward end of the perimeter flange of the dome, in the forward end of the perimeter flange of the deflector, or in both, and an outlet at the opening;
- wherein the perimeter flange of the dome contacts the perimeter flange of the deflector at a surface, and at least one of the plurality of cooling holes extends through the surface.
A gas turbine engine defining an axial direction, the gas turbine engine comprising:
- a combustion section comprising a combustor assembly, the combustor assembly comprising:
- a dome comprising a perimeter flange, the perimeter flange having a forward end;
- a deflector positioned adjacent to the dome and also comprising a perimeter flange defining a forward end, one or both of the dome and the deflector defining an opening, a component axis extending through the opening, and a radial direction relative to the component axis;
- and
- a retainer comprising an outer member contacting the perimeter flange of the dome, the perimeter flange of the deflector or both, the outer member of the retainer defining at least in part a retainer cavity inward of the outer member along the radial direction;
- wherein the dome, the deflector, or both define a plurality of cooling holes for providing a cooling airflow from the retainer cavity to the opening;
- wherein the plurality of cooling holes each extend between an inlet defined in the forward end of the perimeter flange of the dome, in the forward end of the perimeter flange of the deflector, or in both, and an outlet at the opening;
- wherein the perimeter flange of the dome contacts the perimeter flange of the deflector at a surface, and at least one of the plurality of cooling holes extends through the surface.
