DLRmagazine 173 (October 2023)

Winds of change

This wind turbine on the cover of DLRmagazine 173 is far from conventional: it is equipped with numerous sensors right up to the blade tips, and it is part of the new DLR Wind Energy Research Park WiValdi. Here, experts from science and industry can conduct research with an unprecedented level of detail under real environmental conditions. The DLR camera HRSC on board ESA's Mars Express probe also achieves an extraordinary level of detail: It has been delivering high-resolution images of our neighbouring planet for 20 years. This issue shows the highlights of this special mission. DLRmagazine 173 also talks about less plastic in waters, a method for analysing synthetic fuels, and much more.


In music, the term 'opus' is used to help identify the work of an artist. The wind turbine featured on the cover of issue 173 of DLRmagazine shares this name. It is more than a conventional wind turbine – from its foundations to the tips of its blades, it is equipped with numerous specialised sensors. DLR researchers will use the data acquired using these sensors to investigate how the noise generated by future wind turbines can be reduced or eliminated, among other things. That is why OPUS 1 is not alone. This facility is part of the new DLR Wind Energy Research Farm known as WiValdi, which is short for 'Wind Validation'. Here, experts from research and industry can conduct research at full scale with an unprecedented level of detail and under real environmental conditions. The goal is to better understand wind power as a whole, with all its influencing factors.

In addition to wind energy research, the latest 'opus' of the DLRmagazine contains many other interesting articles that, among other things, highlight the extensive topic of environmental compatibility from different perspectives. The article on prescreening describes a process that DLR experts use to analyse the components of synthetic kerosene alternatives. The article on the DLR Projektträger's 'Plastic Pirates' initiative discusses the protection of bodies of water from further pollution. Across Europe, schoolchildren are collecting litter from streams, lakes and rivers. The information they gather will expand the understanding of what types of waste enter the ecosystem and how they are distributed geographically. Doing more to protect the environment is also one of the core aspects of the sustainability concept that has become increasingly important within DLR in recent years. You can find out more about this in the interview with Anke Kaysser-Pyzalla, Chair of the DLR Executive Board, and her deputy, Klaus Hamacher.

For this issue, too, we have spared no effort – a literal meaning of the Latin word 'opus' – to ensure that the following pages are once again full of enjoyment and insight.
