Cost reduction is indispensible to further strengthen the competitiveness of sustainable energy production. Blade inspection and repair of ageing wind turbines, for example, is usually time-consuming and cost-intensive. It offers high potential to reduce operating costs through more efficient maintenance procedures. Together with BIMAQ, we are currently exploring the possibility to monitor damage and contamination level of wind turbine blades using noninvasive remote detection of laminar-turbulent flow transition via infrared thermographie (IRT) [1, 2].more...

Quantum physics is becoming more and more attention from science and economy. Often alkali-metals evaporated in an ultra-high vacuum are used as source for quantum technologies. Recently we developed a filling facility for alkali-metal sources such as ovens or dispenser in our laboratories. The next step is to qualify existing ovens with a saturation spectroscopy unit for space based missions.more...

Quantum physics is becoming more and more attention from science and economy. Often alkali-metals evaporated in an ultra-high vacuum (UHV) are used as source for quantum technologies. Additionally, optical accesses are used to introduce light fields to the atoms. Due to high thermal and/or high vibrational loads on the UHV seals, build by indium wire, the window seals are degenerating. This causes unwanted leaks to the vacuum system.more...

Die Kontrolle von Schwappbewegungen von Flüssigkeiten ist in vielen Anwendungen eine große Herausforderung. Die Problematik erstreckt sich dabei von Tankschiffen, deren Flüssigladung von den Ozeanwellen in gefährliche Bewegungen versetzt werden können bis hin zu modernsten kryogenen Raketenantrieben bei denen das Schwappen sogar zur Zerstörung der Rakete führen kann.more...
