Aeroelasticity is like a kind of black hole ... the darkest source of infinite curiosity across Universe.
"Lies are like flies, they fly everywhere and pose where the sweet smell of curiosity is strongest" (Pio Rossi). And those who unscrupulously plagiarize are "vagrants of knowledge."
We continue studying and learning every day… thanks to a lot of people and colleagues who share their achievements and time, even during these hazardous times.
And, paraphrasing the discovers of Cygnus X-1… , “it might be galloping”.
Happy 2020 Easter to everyone!

Our Group (GIFD, Department of Energy, University of Oviedo) is developing a new method to calculate the structure of the Photovoltaic Solar Trackers against the effect of wind. Due to the lack of knowledge (there is only a little scientific knowledge because this is a very new and recent issue) we found in the national and international standard and codes, a few of laboratories and wind tunnels all over the world are trying to find out what is the aeroelastic mechanism which causes such a disaster called torsional galloping or 1DOF flutter.
We leave herein below one of our 2D CFD approaches, showing a real case of a single axis solar tracker placed at 30º of initial tilt angle panel and oscillating at 1,2 Hz and moderate amplitudes, under wind speed of 20 m/s.

I'm going to start to point out the work of my pupils. I think this is the reason of the work at University, I mean, the students. So, today I would like to mention the excellent TFG carried out by Pablo Canseco and Edgar Imaz.
The have been worked in the development of a new movable scaffolding system and the study of the reconstruction of the port of Cudillero, Asturias, Spain, after the heavy storms in 2013 and 2014.
Congratulations for your results.

I do not believe in QUALITY. I do not believe in surveys. I do not.
At least when this things are going together and are used by ignorants with the aim of pretending knowing.
So let me share this paper with you and you will see. Yo will become truly non believer like me. Or much better than that, you will only believe in real things, important things, reasonable things.

This is like a motto, something that you must keep in mind when you find in your way someone who never should have got power over others.

The first edition of this Competition took place last year at University of Oviedo (E.P.M. and E.P.I.G.). It was a nice experience, 50 students ran for the prize and we all learned a lot, I hope so.

A really interesting conference.

Some investigations have led experts to assess that G. Eiffel designed a steel truss bridge in Asturias: the "Parana" Viaduct in the railway from Lena to Pajares.

The story ended in 1954, when someone decided that the bridge was no longer available for the new convoyes...
