Abstract
An annular combustor for a gas turbine engine is constructed to include a sector that has a reduced airflow distribution than the remainder of the circumference by supplying a reduced airflow in a judiciously located portion of the fuel nozzles and the single stage of radially ingested combustion airflow. This single stage circumferential zoned annular combustor serves to accommodate higher fuel/air ratios.
