During Project AAFEX, PM emissions measurements were conducted on a CFM56-2C1 gas turbine engine in January 2009 in Palmdale CA. The engine was mounted on a NASA DC-8 aircraft, which was parked on the runway, and emission samples were extracted at the engine exit plane (1m), in the near field (30m), and in the advected plume (145m). The engine was operated at several power levels, and burned several fuels: JP-8, a Fischer-Tropsch fuel derived from natural gas (FT1), and a second Fischer-Tropsch fuel derived from gasified coal (FT2). In addition to these fuels, 50:50 blends of the Fischer-Tropsch fuels and JP-8 were also studied. Wide variations in ambient temperature, especially between early morning and late afternoon were experienced during the campaign. This report summarizes and describes the results of AAFEX, in terms of the influence of ambient temperature on total PM emissions at the exit plane of a CFM56-2C1 engine.
