<P>PROBLEM TO BE SOLVED: To provide a pegless secondary fuel nozzle. <P>SOLUTION: A unitary fuel injection manifold for the secondary fuel nozzle improves fuel-air mixing and offers flexibility to alter the mixing profile through adaptability to a variety of number, types, and orientation of discharge outlets to the combustion air mixing space around the secondary fuel nozzle. An aerodynamic surface with reduced extension into the mixing space reduces pressures drop and interference with design airflow. Manifold integrity is enhanced by elimination of fillet welds to mount external pegs. <P>COPYRIGHT: (C)2012,JPO&INPIT |
