Aircraft emissions characterization. Final report, September 1986-August 1987

Technical Report ·
OSTI ID:6662235
Assessment of the environmental impact of aircraft operations is required by Air Force regulations. This program was undertaken to quantify gaseous and particulate emissions associated with three Air Force turbine engines (TF33-P3, TF33-P7, and J79 (smokeless). The emissions tests were carried out, using a test cell at Tinker AFB, Oklahoma City, OK. All tests employed JP-4 as the fuel, and fuel samples were characterized by standard tests and analyzed for composition. Emissions were measured at power settings of idle, 30%, 75%, and 100%. Measurements were made of detailed organic composition, CO, CO/sub 2/, NO, NOx, smoke number, particle concentration, and particle-size distribution. A multiport sampling rake was used to sample the exhaust, and heated Teflon tubing was used to transfer exhaust to the monitoring instrumentation. Measured and calculated fuel/air ratios were compared to assure representative sampling of the exhaust. The results have been used to calculate emission indices and emission rates for CO, CO/sub 2/, total hydrocarbons, NO, NO/sub 2/, and NOx. The distribution of organic compounds in the exhaust from the different engines and at various power settings was compared, and the distribution by compound class and by carbon number are reported. Smoke numbers and particle-size distributions were derived from the test data. The report also contains a review of the emissions of selected toxic chemicals, and a comparison with other emission sources.
