Abstract
A gas turbine engine combustor includes outer and inner liners joined together at an annular dome. Outer and inner air swirlers and cooperating fuel injectors are mounted in two rows in the combustor dome. The fuel injectors are joined to a common fuel manifold for simultaneously channeling fuel thereto over an operating range from idle to full power for reducing exhaust emissions.

A gas turbine engine combustor comprising:
- an annular outer liner spaced from an annular inner liner, and joined at forward ends to an annular dome;
- a plurality of outer and inner air swirlers, mounted at apertures in said dome in two radially spaced apart rows;
- a plurality of outer and inner fuel injectors, mounted in respective ones of said outer and inner swirlers;
- and
- means including a fuel manifold joined in flow communication with both said outer and inner fuel injectors for simultaneously channeling fuel thereto over an operating range from idle to substantially full power for producing combustion exhaust gases.
A gas turbine engine combustor comprising outer and inner liners joined together at an annular dome having two rows of radially outer and inner air swirlers, and means for simultaneously injecting fuel through both swirler rows without outer and inner fuel staging therein over an operating range from idle to substantially full power.
