Micromix fuel injection air nozzles

A fuel-injection manifold comprising:

• a main body that includes a plurality of air nozzles that each defines a flow path along a first axis and comprises an outlet, wherein the plurality of air nozzles are arranged in one or more rows along a second axis and one or more columns along a third axis that is orthogonal to the second axis;
• and
• for each of the one or more rows, a fuel supply that includes
• a fuel chamber that extends along the second axis, and
• for each of the plurality of air nozzles in that row, at least one fuel jet that provides fluid communication between the fuel chamber and the flow path defined by that air nozzle.

A gas turbine engine comprising:

• a compressor;
• a combustor downstream from the compressor, wherein the combustor includes one or more fuel injectors, and wherein each of the one or more fuel injectors includes a manifold that comprises a
• a main body that includes a plurality of air nozzles that each defines a flow path along a first axis and comprises an outlet, wherein the plurality of air nozzles are arranged in one or more rows along a second axis and one or more columns along a third axis that is orthogonal to the second axis, and
• for each of the one or more rows, a fuel supply that includes a fuel chamber that extends along the second axis, and for each of the plurality of air nozzles in that row, at least one fuel jet that provides fluid communication between the fuel chamber and the flow path defined by that air nozzle;
• and
• a turbine downstream from the combustor.
