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!
