By using a multitude of channels and platforms, we manage to address a diverse audience – at least in theory. In practice however, our audience tends […]

Urban Climate: Simulating the effect of building orientation on cold air streams

Due to climate change, cities will increasingly have to deal with extreme heat events during the summer season. After 2003 and 2015, 2018 was another year with a summer that brought above-average temperatures in Switzerland during which excess mortality was observed (2003: 6.9%, 2015: 5.4%, 2018: 3.4%, source: BAFU, 2019). Therefore, it becomes increasingly important […]

Project RAPTOR: Second test campaign at the Gas Turbine Research Centre in Wales

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 […]

Paper published: First reported nonvolatile particulate matter emissions of a business jet aircraft measured according to a new international emissions standard

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, […]
