In research, results are usually shared through papers, posters, or presentations. What often remains unseen is the extensive preparation behind an emissions measurement campaign. For our current project ADVISAR (ADdressing feasibility studies toward cleaner aVIation and environmental impacts research with SAf on unRegulated engines), we conducted emissions measurements with two different fuels at Stans Airport […]
During the Silvester fireworks in and around Zürich, many of you probably noticed that the air became foggy at some point. This can be explained by particles, emitted from the fireworks, accumulating in the boundary layer and acting as condensation nuclei for water droplets, which together with the air moisture and temperature led to fog […]
Summary: A research team from the National Institute for Environmental Studies, Zurich University of Applied Sciences, Tokyo Metropolitan University, and other institutions (hereinafter referred to as “our research team”) conducted emission tests on aircraft engines and examined the shapes and internal structures of the exhaust particles with high-resolution transmission electron microscopy. Our research team identified […]
On April 2, the Swiss Power-to-X Innovation Network SPIN celebrated a very special anniversary at its General Assembly: 100 years of Fischer-Tropsch synthesis. In 1925, chemists Franz Fischer and Hans Tropsch developed a process for converting carbon monoxide and hydrogen (synthesis gas) into long-chain hydrocarbons – an important step that today plays a central role […]
If you’re a frequent reader of our blog, you already know that we’re deeply invested in air quality — particularly when it comes to the impact of transportation. Whether it’s engine emissions, field measurements, lab studies, or targeted campaigns, we’ve done it all. If you’re new here, you’ve arrived at an exciting time! We’re taking […]
If you have ever owned a car, you are probably familiar with the mandatory (bi-) annual emissions test, which were introduced to ensure that wear and tear on the engines do not have a negative impact on the exhaust gas quality. And even if you have never owned a car, chances are that this connection […]
Overview Airborne pollutants can have negative physiological impacts on passengers and crew members in the short- and long-term, hence aircraft cabin air quality is very important to human wellbeing. Due to their detrimental effects on human health, volatile and semi-volatile organic compounds, also known as VOCs and SVOCs, must be eliminated from the cabin air. […]
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 […]
The International Civil Aviation Organization (ICAO) requires that engines of maximum rated thrust greater than 26.7kN be certified for their emission performance[1]. For certification, ICAO defined four power modes in an aircraft’s landing-take-off (LTO) cycle as emission test points. These modes include idle/taxi at 7% of the maximum rated thrust (Foo), approach at 30% Foo, […]
Written by: Thomas Rötger On 7 October 2022, at the end of 2 weeks of negotiations during the 41st ICAO Assembly, the 193 ICAO Member States took the historic decision to adopt a collective long-term global aspirational goal (LTAG) of net-zero carbon emissions of international aviation by 2050. This resolution was based upon a report on the […]
