[edit] Shocked this wasn't made earlier
I'm shocked this wasn't made earlier. *applauds* Vitriol 17:36, 28 February 2006 (UTC)
[edit] Falling out of the airstream?
"Outdoor vertical wind tunnels may also have walls around the wind column, to keep flyers from falling out of the wind."
I heard (not sure) that the "flyers" are actually held in the middle of the wind column (maybe by the Bernoulli Principle?), thus there would be no danger of them falling out. Does anyone have any information on this? I'll come back if I learn anything. Thanks. Kudos on an excellent article! :-) --64.110.250.80 03:55, 1 March 2006 (UTC)
Not really. You can "bodyfly" your way out of any vertical wind tunnel airstream. So that's why there are cushions or netting around any open-air windtunnel. You still need to have some bodyflight techniques to keep yourself centered in a vertical wind tunnel. Some of them even have laminar airflow so the speed is the same almost all the way to the edges of the airstream.
To illustrate the proof that a human can easily out-bodyfly the Bernoulli Principle.... As a novice skydiver myself (CSPA B-5386), I should add professional skydivers can accelerate up to approximately 100mph of horizontal motion in a "tracking" manoever, to make them look like they are falling at a 45 degree angle (Falling 100mph while moving horizontally 100mph, for example... This requires a trained body position: body acting as a very crude glider airfoil shape). Tracking is a manoevere that is also demonstrated in videos in the 400-way formation skydive at [1]. Near the end of the skydive in the video, people start to rapidly accelerate horizontally at breakneck speeds away from the falling formation to gain airspace to safely open their parachutes (canopies). As you can see in the videos, the human body can still massively out-bodyfly insignificant forces like Bernoulli Principle. Mdrejhon 17:21, 1 March 2006 (UTC)
Neat-o! That's pretty cool. As asker of the above question, thanks a million for the answer. (I searched all over and couldn't find anything.) A friend and I were wondering after we saw the Olympics performance. Thanks again for such a great answer! (These talk pages are just as useful as the actual article!) All the best in your future skydiving adventures. --Sboots 00:34, 6 March 2006 (UTC)
[edit] Please keep this article encyclopedia-like
Someone made several helpful corrections, while adding a lot of other errors. However, it forced me to have about 30+ minutes of corrections since run-on sentences, grammar errors, and some slang (exclamation marks, fully-capitalized words) which were were added. Can we please make this more of an encyclopedia entry and less of a marketing article. I moved the safety/marketing notes to a separate paragraph, since they seem relevant to the article. I've fixed all the problems that I know of. Thanks. Mdrejhon 17:20, 1 March 2006 (UTC)
[edit] Edit Wars to add commercial windtunnel links
I have talked to a Wiki volunteer and we agreed to leave out all the commercial links and just list the Bodyflight directory. I think it's consensus that a directory serves the purpose. Mdrejhon 2006
Addendum: Wind tunnel employees have started abusing this article again by tooting their tunnel. Sigh. Time to prune the "External Links" section yet again. On the other hand, SkyVenture probably merits its own link due to their leadership (i.e. they are the Microsoft of indoor skydiving right now -- biggest market share), but individual franchaises of SkyVenture should be deleted since they are multiplying like rabbits over the last few years.
