Ground-based In-situ PM Emissions Characterization during NASA's ND-MAX Campaign Using SAE Aerospace Recommended Practice.
Abstract
Ground-based in-situ measurements, of the non-volatile PM emissions from V2500 engines of the DLR ATRA research platform burning specially selected baseline jet fuels and sustainable alternative jet fuel blends, will be reported. These measurements have been made as a part of the NASA DLR FAA NRC sponsored ND-MAX, ECLIF2 campaign. These measurements were obtained using the North American Reference System (NARS) a regulatory tool developed to determine the number and mass characteristics of commercial jet engine emissions. The NARS was enhanced to provide concomitant size distributions additional mass measurements using an Aerodyne CAPS and composition analysis using a time of flight aerosol mass spectrometer (cTOF AMS). Associated with the enhanced NARS measurements were data sets acquired by groups from NASA and the NRC using similar measurement techniques but not configured to explicitly mimic the recommended practice. In the case of the NASA ground-based system it was configured to emulate the PM mass, number and size measurement systems deployed by NASA in the flight component of ND-MAX. Therefore along with the NARS fuel specific data, comparisons will be made between the NARS results and those reported by the NASA and NRC measurement groups.
