  • Expanding competence in emissions measurements on various engine types
  • Continued investigation of emission characteristics (non-volatile particles and gaseous pollutants) of large aircraft turbofan engines and the effect of engine age on their emissions
  • Research & development for the improvements of the ICAO / SAE E-31 methodology for sampling and measurement of non-volatile PM (nvPM)
  • Emissions characterization of aircraft engine types which are unregulated in terms of emissions – turboprop, turboshaft, and small turbofan engines (e.g. business jets)
  • Funding: BAZL/FOCA
  • Partners: SR Technics
