In spring three years ago, in the middle of the first lockdown of the Covid-19 pandemic in Switzerland, we packed up our measurement system (SMARTEMIS) and drove to Zurich Airport to record unique air quality data near the airport area. At this time, aircraft movements had dropped by more than 90% compared to the previous … Read more
As most of our active followers know, our research group is responsible for the operation, maintenance and optimization of the Swiss Mobile Aircraft Emission Measurement System (SMARTEMIS). Typically, the system is installed in test cell 1 at SR Technics, located at Zurich Airport. In 2022 however, the SR Technics management decided to reactivate their second … Read more

“Achieving sustainability in commercial aviation is difficult, but not impossible. Naturally, engineers try not to create new problems, yet it is important for them to be aware about all factors and influences and not just to focus on solving one issue.” – By D. Romang and C. Waltenspül. As part of their project in AV.PM4, … Read more
Exactly one year after the first measurements at the Gas Turbine Research Centre (GTRC) in Wales, the second measurement campaign was due there. And just like last year, the situation with the COVID pandemic started to deteriorate dramatically just before our departure. After numerous meetings, discussions and clarifications, including the development of strict COVID protection … Read more
Particle emissions of small turbine engines are unknown and unregulated Jet engines for commercial airliners in production now and in the future are certified for particle emissions from a virtual landing and take-off cycle. However, one potentially large group of engines is left out. Small jet engines (<26.7 kN rated thrust), found on business jets, … Read more
