Videos or pics even of a fin flexing under load (in water)

I’m sure the big name fin comapanies must do some in water R&D … Or at least I’m hoping they do, and they don’t just give fins to people and say tell us how they ride… I mean i could think a fin is super flexy were as someone else may say too stiff.Even from wave to wave they may feel differently, day to day, board to board etc… There are a million variables.

Do they do control tests?

I’d like to see some video of a fin in a water tank with water flowing over it, and watch the fin actually flex. I’d like to see the cavitation, release etc… etc…

Why? Cuz I’m just like you guys and I think isht like that is cool.

 

But I can’t find any videos or pics of this. Has anyone seen anything like this and maybe point me to it? I’m just thinking now the one place I didn’t look in ON futures and fcs sites… But you know what, there sites are such crap compared to the rest of the internet I’m not expecting anything there… I mean fcs doesnt even have the fin chooser thing futures has… and dont get me started on scarfinins site. HAHAHA…

 

So uh yeah… I dont post much at all. I do read a lot though, and if someone has seen something as cool as this I like see too!

When Thrailkill was doing his seminar at FCS a few years ago I asked the FCS rep if they actually did water tunnel, hydrodynamic testing, he said,"yes" and then they would surf test them with their riders, with the lab results in mind for the big picture.  A few years ago on Sways there was an English university, academic, or commercial lab?, fin hydrodynamic testing set up that was reported pretty well in their write up on Sways, one of their conclusions was that, fins in general are much more limber than you'd think and that stiffer is better.  If you find it please put a link to it.

I think some of the links on that thread are now broken. 

Type fluid dynamics experiments and air foils etc. into utube and you get some interesting examples of fluids and air over foils and shapes plus angles of attack.
