The Experimental Clean Combustor Program is described. The program objectives include the generation and demonstration of technology for development of advanced commercial CTOL aircraft engines with lower exhaust emissions than current aircraft and the demonstration of this technology in full scale engines in 1976. The program is being conducted in three phases: (1) the screening of low pollutant combustors; (2) refinement of the best combustors; (3) and engine demonstration of the best combustors. Pollution goals are emission index values of 20 and 4 for carbon monoxide and unburned hydrocarbons, respectively, at engine idle conditions and an oxide of nitrogen emission index level of 10 at engine takeoff conditions. Pollution reduction approaches which are being investigated include multiple burning zone combustors, investigations of improved fuel distribution, and preparation and staging of combustor airflow. Phase I of the program is approximately 50 percent completed, and preliminary test results indicate that all combustor designs, with sufficient additional effort, appear capable of achieving the idle pollutant goals. Reduction of NO/sub x/ by 50 percent are presently possible, though further reductions are at the expense of increased combustion inefficiencies at both low and high power conditions.
