Engine fuel injectors with common fuel target location

An apparatus for an engine, comprising:

• a first fuel injector extending axially along a first axis to a distal end of the first fuel injector, the first fuel injector including a first injector flange, a liquid fuel nozzle, a plurality of gaseous fuel passages and an inner air circuit, and the inner air circuit comprises a plurality of air passages and an inner air annulus;
• the first injector flange projecting radially out to an outer rim of the first fuel injector, and the first injector flange circumscribing the liquid fuel nozzle;
• the plurality of gaseous fuel passages arranged circumferentially about the first axis, each of the plurality of gaseous fuel passages extending in the first fuel injector to a respective gaseous fuel passage outlet at the outer rim of the first fuel injector, and a trajectory of each of the plurality of gaseous fuel passages at the respective gaseous fuel passage outlet pointing radially away from the first axis;
• the plurality of air passages arranged circumferentially about the first axis, each of the plurality of air passages extending through the first injector flange to an upstream end of the inner air annulus, and a trajectory of each of the plurality of air passages extending to the inner air annulus pointing radially towards the first axis;
• and
• the inner air annulus extending axially within first fuel injector to an air passage outlet at the distal end of the first fuel injector, a downstream section of the inner air annulus adjacent and upstream of the air passage outlet radially tapering as the inner air annulus extends axially to the air passage outlet.

An apparatus for an engine, comprising:

• a combustor comprising an annular combustion chamber extending circumferentially about an engine axis;
• a first fuel injector disposed at a first injector location, the first fuel injector configured to direct a first stream of gaseous fuel into the annular combustion chamber along a first trajectory towards a target location;
• a second fuel injector disposed at a second injector location, the second fuel injector configured to direct a second stream of the gaseous fuel into the annular combustion chamber along a second trajectory towards the target location, and the second injector location circumferentially spaced from the first injector location about a centerline of the annular combustion chamber;
• wherein the target location is located a first radial distance from the engine axis;
• wherein a first gaseous outlet of the first fuel injector and a second gaseous outlet of the second fuel injector are each located a second radial distance from the engine axis;
• and
• wherein the first radial distance is equal to the second radial distance.
