Almost a year and a half between these two images:
And a lot of hard work, study, trial & error (and last but not least, so many beers at the "Taberna Irlandesa"). Carlos Rodríguez-Casado (#FORMULA WINDY - UO) has achieved a milestone by getting our Smoke Wind Tunnel blowing.
A powerful device for teaching and research on aeroelastic instabilities in bridges, buildings, solar trackers, etc. made in University of Oviedo, in collaboration with IDR-UPM and Princeton University (#ESOLIA #SOLTRACK project). Stay hungry, stay foolish!

ESOLIA & SOLTRACK Team attended the 2024 edition of GENERA in Madrid last week. We presented the DEMO-TRACK, the first portable device ever for teaching&learning&research on the aeroelastic instabilities of single axis solar trackers, particularly 1DOF flutter. General public and companies turned out to be really interested in the matter and the solution we proposed. We also held many meetings with constructors. Really grateful and proud of every one on board. We would like to acknowledge to this event´s sponsors: "Excmo. Ayuntamiento de Mieres" and Polytechnic School of Mieres and to our awesome host IMEnergy Power Plants, S.L. Looking forward to meeting you all again!
 Do not miss anything and learn how to deal with torsional instability (galloping or flutter of single-axis solar trackers) and go for understanding the "Stability Diagram of the Tracker" ("Diagrama de Estabilidad del Tracker").
CPP, one of the pioneer aerodynamic laboratories in the study of solar tracker galloping, says that not all the wind tunnels are the same... and it is true. Well, not all Stability Diagrams for the aeroelastic design of structures are the same either... or are they? Well, if you copy it, then it will match point for point... we usually call it plagiarism (we all should fight this stronger, seriously, I´ve noticed some cases - other disciplines - last month!). Let me explain crystal clear, by telling a tale. This is the original image, obtained two years ago by Dep. of Energy - Uniovi and given to a (hypothetical) company we used to work with. It was named "Diagrama de Estabilidad del Tracker" by the Authors (and it was depicted and properly published after months of huge work and dedication):  And guess what? That figure never reached its intended destination, a third-party (hypothetical, again) company. Now, this is the image that the (hypothetical) company presented in a live webinar (hypothetically speaking) some time ago, pretending it was their own...  And this is the "magic". The less detailed is the image you (well, they, hypothetically) pretend to present, the easier is to "fake" it. A simple geometrical retouching and cutting... and "voilà!", trick comes to the surface.  But beyond some unfortunate anecdotes on the sidelines, the science of civil aerodynamics unites many great engineers all over the globe since decades, each of them trying to do their bit to explain and master the terrible phenomenon of the one degree of freedom flutter. Blessed are the people of good will (the majority, btw)!!! We publish this poster as a tribute to all those who precede and accompany us in this exciting endeavor. By the way, we welcome all the "fake free" contributions that you want to share and include in!  http://openletter.euroscience.org/open-letter-spanish/
Scientists from different European countries describe in this letter that, despite marked heterogeneity in the situation of scientific research in their respective countries, there are strong similarities in the destructive policies being followed. This critical analysis, highlighted in Nature and simultaneously published in a number of newspapers across Europe, is a wake-up call to policy makers to correct their course, and to researchers and citizens to defend the essential role of science in society. The national policymakers of an increasing number of Member States, along with European leaders, have completely lost touch with the reality of research. They have chosen to ignore the crucial contribution of a strong research sector to the economy, particularly needed in the countries more severely hit by the economic crisis. They have chosen to ignore that research does not follow political cycles; that long-term, sustainable R&D investment is critical because science is a long-distance race. They have chosen to ignore that public investment in R&D is an attractor of private investment; that in an “innovation State” like the United States over half of its economic growth has come from innovation with roots in basic research funded by the federal government. They have chosen to ignore that time and resources are required to train researchers. They have chosen to ignore that applied research is no more than the application of basic research and is not limited to research with short-term market impact, as some policy makers seem to believe. They have chosen to ignore how the scientific process works; that research requires experimentation and that not all experiments will be successful; that "excellence" is the tip of an iceberg that floats only because of the body of work beneath They have chosen to ignore the critical synergy between research and education. And foremost, they have chosen to ignore that research does not only need to serve the economy but also increases knowledge and social welfare, including of those with no resources to pay the bill. They have chosen to ignore, but we are determined to remind them because their ignorance can cost us the future.
