Dr. Miake-Lye's work is directed toward understanding the environmental impact of airplanes, focusing on the physical and chemical evolution of exhaust flowing from propulsion systems. Field studies, such as APEX1-3, AAFEX, and several military engine tests, as well as sub-scale physical models, and numerical models have been pursued to assess problems related to system performance, engine emissions characterization, and contrail formation. A tunable diode measurement technique for trace gas emissions has been developed and is being applied in support of the emissions characterization effort. In addition, a new Aerodyne measurement technology, the Aerosol Mass Spectrometer, is being applied to characterizing the particle emissions from aircraft engines. Additional advanced techniques are being developed for both particle and gaseous species measurements in parallel with on-going improvements in related microphysical modeling. One major thrust of these efforts is to understand the effects of emissions from gas-turbine engines powering the commercial aviation fleet, both existing and planned, on the global atmosphere and as a contributor to regional air quality. In addition to these research efforts, Dr. Miake-Lye serves on the SAE E-31 committee, Aircraft Engine Emissions Measurement, and was committee chair for five years. This committee writes Aerospace Information Reports and Aerospace Recommended Practices specifying measurement procedures for characterizing emissions from aircraft engines. He is currently Research Focal Point for Local Air Quality to the International Civil Aviation Organization's (ICAO's) Committee on Aviation Environmental Protection (CAEP), and supports its working groups on environmental issues.
