Low emissions combustor for a gas turbine engine

A combustor for a turbine engine, comprising:

• an outer liner having exactly one row of circumferentially distributed outer combustion air holes penetrating therethrough, the outer holes comprising larger size major outer holes and smaller size minor outer holes circumferentially intermediate neighboring pairs of major outer holes;
• an inner liner circumscribed by the outer liner and having exactly one row of circumferentially distributed inner combustion air holes penetrating therethrough, the inner row of holes being substantially axially aligned with the outer row of holes, the inner holes comprising larger size major inner holes, circumferentially offset from the major outer holes, and smaller size minor inner holes circumferentially intermediate neighboring pairs of major inner holes;
• and
• an array of fuel injectors, each injector being substantially circumferentially aligned with a major outer combustion air hole.

A combustor for a turbine engine, comprising:

• an outer liner having exactly one row of circumferentially distributed outer dilution air holes penetrating therethrough, the outer dilution air holes comprising larger size major outer holes and smaller size minor outer holes circumferentially intermediate neighboring pairs of major outer holes;
• an inner liner circumscribed by the outer liner and cooperating therewith to define an annular combustion chamber, the inner liner having exactly one row of circumferentially distributed inner dilution air holes penetrating therethrough, the inner row of holes being substantially axially aligned with the outer row of holes, and the holes of the inner row being circumferentially offset from the major outer holes;
• and
• a combustor front end assembly serving as the exclusive vehicle for introducing primary combustion air into the combustion chamber.
