Abstract	The paper illustrates an aero-engine exhaust emission study, which involves successive simulation procedures for aircraft flight, engine, combustor operation and exhaust emissions. It reveals a generic approach to analyze the effect of changes in flight conditions, power settings and combustor parameters on exhaust gas composition. Using reference measurement data at given engine operating points, pollutant models can be tuned to predict absolute concentration values at altered conditions. Emission formation processes were analyzed in the study using multi-reactor combustor models. The so-called principal pollutants of NOx, UHC, CO and soot were modeled over a broad range of engine power settings at static sea-level conditions. Modeling results were benchmarked against and tuned to emission certification data for a large commercial turbofan. CFD methods were employed to cross-check solution procedures for the engine combustor at the design operating point. Pollutants were also simulated in cruse conditions. Different flight conditions were considered using cross-linked engine and aircraft performance models.
