Project APEX (Aircraft Particle Emissions eXperiment) was a multi-agency commercial aircraft emission characterization and technology demonstration experiment. Its objective was to characterize particle and trace gas precursor species in the emissions from a NASA DC-8 aircraft with General Electric CFM56-2C1 engines at the engine exit plane as well as selected down stream locations. This was to advance the understanding of particle emissions and their evolution in the atmosphere from a current in-service turbofan engine. The test was conducted at the NASA Dryden Flight Research Center at Edwards Air Force Base California during April 15-30, 2004. Participants included the National Aeronautics and Space Administration, Environmental Protection Agency, Federal Aviation Administration, Department of Defense, the aviation industry (General Electric, Pratt and Whitney, and Boeing), and the research community (Aerodyne Research Inc., Massachusetts Institute of Technology, Process Metrix, University of California-Riverside, and University of Missouri-Rolla).
