An airblast fuel atomizer was developed to reduce smoke emission levels in FJR-710 engines. Rig tests were made to determine performance and pollutant emissions of the airblast annular combustor over a wide range of inlet pressures and temperatures with nonuniform airflow distributions. No significant problems were observed for flame instability nor for combustor durability. Smoke measurements showed considerably lower levels than conventional pressure-atomized combustors with similar liner configurations. Smoke level at full engine thrust was found to meet the 1984 EPA standard for T2-class engines. Nox-emission levels were below Lipfert correlation data available for existing aircraft engines.
