The MERMOSE project: characterization of particulates emissions of a commercial aircraft engine: from morphology to chemical composition

Abstract : During this project a field campaign has been permormed behing a complete SaM 146 aircraft engine at Snecma test bench. Together, ONERA, IRSN, Snecma and CNRS (CINaM, PhLAM) made gas and particles measurements with a single hall probe that allowed sampling at 5 cm behind the engine exit. Cartographies through 16 points at various engine thrust has been done, from 30% engine maximum take-off thrust to 100%. The experimental set-up has been composed of 4 lines, all connected to the same probe. The first one was dedicated to gas measurements following the certification guidelines (ICAO, 1993). One line dealt with sampling for laboratory characterizations, microscopy (TEM) and chemical analysis (EC/OC ratio, EDX, FTIR). Taking account SAE E-31 recommendations, two lines have been built to make on-line monitoring of size distributions (SMPS+C, SMPS+E, DMS 500), mass (MAAP, Pegasor, filters) and number (CPC, Pegasor, DMS 500) concentration densities and particle surface area density (NSAM).
