Wind Tunnel for Birds
bgood writes "'What, a swallow, carrying a coconut? ...' The Department of Animal Ecology at the University of Lund in Sweden uses a modern low-speed wind tunnel specially crafted for bird experiments. The birds are trained to fly in the 'test-section' and the tunnel can be tilted up or down to simulate ascent and descent. This link contains plenty of detail, complete with bird pictures. For those of you who yearn to build your own (non-bird-compliant) wind tunnel, you can find instructions in this Scientific American article."
I'd imagine that the birds would eventually figure out that they can just glide and not have to flap their wings? I mean isn't that what airplanes do?
we want more Heather
Imagine a Beowulf cluster of these shoved up your ass sideways
BSD Daemons rule!
I don't find animal cruelty that cool.
What would I use it for?
I suppose if anything it would be cool to see how paper airplanes and mini-kites work before building larger versions of them, and I could model my own planes, I could see how those work too.
Sounds like a fun project, if I had the time and resources.
I have 3656.9 Bogomips. How many Bogomips do you have?
Well, It seems like a bunch of scientists have got drunk and high, and decided a new way to have fun watching birds trying to fly at high speed winds. In the meanwhile making it look like scientific research. Most major science discoveries were caused by scientists being high. The names of the subatomic particles for instance so the may actually be on to something, or they are just having fun.
When other guys are domesticated and get assigned to put the birdhouse in the backyard it's a 20-minute trip to Home Depot and 5 minutes hammering the thing to a tree.
Is this truly the only Earth I can live on?
This could prove to be very useful in figuring out how to build a flying robot that mimics a real bird. You could fly one of these things behind enemy lines, undetected, and spy on damn near anything you want as close as you want. Pretty far off in the future yet but a definate possibility.
It would be fun to crank the sucker up and watch the birds struggle and eventually give up and get blown and smashed into the back of the tube, quacking or chirping frantically.
Or, even better, turn the fan on in reverse and watch them try to waddle and hop against the suction.. slowly getting stronger.. and stronger.. the bird finally can hold no more and WOOSH BZZZZZZZT SPLUT bird guts EVERYWHERE! Whoopsie!
I'm going to vomit before I go to bed now.
Thank you Slashdot!
What, a swallow, carrying a coconut?
Now as long as we don't run into the Knights that say Ni.
Shh.
I'm sure there would be at least some scientific use for these experiments.
I can understand wanting different angles of flight, but why do you have to tilt the whole aparatus? It would seem that being able to tilt the whole wind tunnel would be a rather difficult (ie expensive) engineering constraint.
Is there a good reason you couldn't work out some sort of flexible tubing or other solution so that part of the tunnel could be bent appropriately without moving the whole thing? Would the effect on the air flow be so disruptive that you couldn't correct for it?
...this thing is for the birds!

One of the most interesting things I ever saw in a nature flick was a clip of an eagle grabing a big fish out of a lake. The fish was so big that the eagle was only able to gain altitude very slowly.
But the interesting thing was the way the eagle handled the fish. It came up from the water with the fish turned sideways in its two feet, but over a period of several seconds it shuffled its grip on the fish and turned it pointing forwards, the way a fish swims in the water -- presumably to reduce the aerodynamic drag on it.
Sheesh, evil *and* a jerk. -- Jade
... using the phrase "window(s) on the world" in an article talking about flying stuff.
I have no idea why someone would want one, but just imagine...
Well, *my* wind tunnel is 100% OpenSwallow 2001 compliant, and supports remote control through /dev/windtunnel. :-)
This site is fucking gay.
A bird treadmill! I love it!
Wrists killing you? Not in 2 weeks. Learn Dvorak.
This method only displays the surface information.
If they could fix up an MRI (Magnetic Resonance Imaging) machine they could also get information on muscle use and blood flow.
Now that would be neat.

Interesting story over at CCN. Seems that the young Ms. Clinton is over in the UK at Oxford University. Shes having a bit of a hard time with anti-american feeling, and only wants to be around yanks.
The final bit:
>Chelsea Clinton is studying for a Masters degree in international relations.
made me piss myself. As a side note, I hate the yanks, I much prefer a long, slow wank.
Now I can finally test my penis in a wind tunnel and find out how to maximize its fucking potential.
i think most everyone figured this out serveral years ago.
Can anyone here help? I feel so incomplete without a one.
THE OFFICIAL TACO-SNOTTING FAQ

What is "Taco-snotting?"
Have you ever been Taco-Snotted? Why am I always receiving emails from CmdrTaco asking me if I would allow him to Taco-snot me? I can't stop receiving these emails from CmdrTaco!? What is a "Circle-snot"? Does Jon Katz get involved in this? I thought he was a paedophile, not a homosexual.$Id: tacosnotting.txt,v 1.4 2001/11/11 02:00:45 wipo Exp $

I wonder if people racing pigeons will buy these for pigeon training.
A man goes to visit his doctor,
"Doc, I've got a rather embarassing problem, my farts just don't sound right,"
"Well how do they sound?" enquires the doctor.
"They make a HONDA sound"
The doctor looks puzzled, "Hmm, is there anything else I should know?"
"Well I also have a terrible boil on my arse," replies the man
The doctor looks pleased, "Thats it then. We'll lance that boil and you'll see a difference immediately,"
"Why's that then, Doc?" asks the man
"It's well known," laughs the Doctor, "Abscess makes the fart go Honda."
I dare you to bloat your goat!
Whats interesting for me tho, is what can be learned about wing design from these birds. I don't know if a wing that really "flaps" could ever be used, but surely there must be some good "science" in the flow patterns which can be observed from a large wing in a "glide" setting. Although I doubt the tunnel is big enough for an albatross...
Anyways, interesting science from the Swedes.
I was wonder what was the best way to drive up your guy's asses? If you'd tell me I'd really appreciate it.
I mean whats the deal here, hundreds and hundreds of thousands of geeks here talking about birds and windtunnels. Could it really get more pathetic. I hope you all choke on a fucking bottlecap or get hit by a fucking bus on your way home from where ever it is your geeks work. That is if you geeks have ever even seen the outside of your house since you were drove home from the hospital when you were born. Unless your mother was a whore and you were born in the toilet of a lesbian bar somewhere in Kentucky.
Thanks people, its great that I have a way to express myself.

What is "Taco-snotting?"
:)
:) :)
:) Join me in a WIPO-snot? I promise I won't try and rape you, chain you up in my basement, and make you my pony for the rest of your life. I'm not like CmdrTaco; I only enjoy snotting on willing partners.
...So, join me in a WIPO-snot?
"Taco-snotting" is a term used by Rob Malda of Slashdot, otherwise known as CmdrTaco, to refer to the practice of sucking off a homosexual man (or unwilling heterosexual) and blowing the semen back out his nose onto the other man's face or body. Usually a long stream of semen is left on CmdrTaco's face, dribbling out of his nose: hence the term, "Taco-snotting."
Have you ever been Taco-Snotted?
Unfortunately, yes. I met CmdrTaco at an Open Source convention and he invited me back to his room for a game of Quake. When I got to his room, he jumped me and tied me to his bed, naked. He Taco-snotted me three times over the next two hours, sucking me to orgasm then snotting my semen onto my face, in my mouth, then again on my belly.
CmdrTaco invited several of his Open Source convention (or rather, Open Sauce convention -- man sauce) buddies over to continue the snotfest. Linux Torvalds raped my ass with his monolithic kernel, and Anal Cox used his network stack in various unspeakable ways on every orifice in my body.
How did I finally escape? After about 16 hours of nonstop homosexual atrocities, they all went to sleep. I was left there, covered in jizz-snot, chained to the bed. Fortunately the cum worked wonderfully as a lubricant and I was able to squirm my way out of the handcuffs and slip out the back door. I'm just glad I survived the ordeal. These geeks had a lot of built-up spunk in their wads, I could've easily been drowned.
Why am I always receiving emails from CmdrTaco asking me if I would allow him to Taco-snot me?
You may have recently received an email similar to the following:
From: malda@slashdot.org
To: wipotroll@hotmail.com
Subject: Hey, baby - jion me in a taco-snott!
Hey, baby!
Ever done a Taco-snotting with anothar fellow geek? Its more fun then trolling Slashdot, trust me! All that talk you troll with about homasexual incest and stuff got me all horny and hot for you! Is it serius? Please tell me that itt is! If you want to get with me and my Slashdot bois, drop me an emale!
ps- Please replie to me at horny_rob_6969@hotmail.com. I'd rather the guys at VA Linux are not seen this.

CmdrTaco (malda@slashdot.org)
You most likely forgot to uncheck the "Willing to Taco-snot" checkbox in your preferences. Whenever CmdrTaco gets bored, he roams through the Slashdot database, penis in hand, looking for people who might enjoy being Taco-snotted. And this time, he found you. Lucky you.
CmdrTaco has probably already got the hots for your wad, and there's no escaping a geek in heat, so it's probably too late... but you can possibly rectify this situation. To remove yourself from the listings, log into your Slashdot account, go to your user page, click on Messages, and uncheck the box next to "Willing to Taco-snot."
I can't stop receiving these emails from CmdrTaco!?
Probably not. If you indulge him in a Taco-snot or two, he might leave you alone. You might also want to look into mail filtering, or purchasing a heavy, blunt object to ward off rampaging homosexual geeks in heat. Trust me, when they charge... oh, the humanity. If he gets you, and you let him Taco-snot you, he might chain you up in his basement and use you as his sex slave for the rest of your life -- or until he accidentally drowns you in spunk while using you as his sex pony in a "circle-snot." It very nearly happened to me.
What is a "Circle-snot"?
A "circle-snot" is a Taco-snotting circle-jerk: When CmdrTaco, CowboiKneel, and Homos get together and Taco-snot each other with their gooey, hot and sticky cum, spooging all over each other's faces and bodies until they're covered with their sticky, sweet man juice. Roblowme usually provides extra lubricant; he owns a limo service and has ample supplies of motor oil and axle grease.
To complete the circle, Michael, Timothy, and Jamie sometimes join in, dressed in Nazi Gestapo uniforms, jack boots, and leather gloves. They all then proceed to snot each other's cum and whip each other's asses with riding crops and cattleprods until their pasty, white geek bodies are exhausted from all the passionate, homosexual revelry.
Does Jon Katz get involved in this? I thought he was a paedophile, not a homosexual.
Actually, he's a homosexual paedophile. He's also a coprophiliac, and a zoophile. Jon Katz is somewhat of a loner and doesn't involve himself in circle-snots. Mr. Katz usually engages in a game called "Katz juicy-douching" with his harem of little boys, which involves administering an enema to himself of little-boy urine, spooging the vile muck from his ass back into the enema bag, then slathering the goo all over himself, and the little boy's chained up and naked bodies. Unwilling boys are tortured with pliers until they comply and allow Mr. Katz to juicy-douche them for the rest of their lives.
As I already said, Mr. Katz is also a zoophile. As if the sexual escapades with the helpless little boys aren't enough, Jon usually enjoys his juicy-douches best when his penis is firmly planted in a goat's anus. He is also rumoured to get off on watching his little boys eat the goat's small, bean-like turds.
...Are you getting hard writing this?
Why, yes.
What's that screaming I hear coming from your basement?
Oh, that's just my sister; I got her chained up in the basement. In fact, I just finished snotting all over her body. You should see her squirm when I spooge on her belly, lick it up, and snot it all over her face. She's such a feisty little 14 year-old bitch. Of course she's my sex slave, she's my sister. What else would she be good for?
No, thanks. I'm already CmdrTaco's boi toi.
ain't that right cmrdtaco. you call yourself taco cause your a hooded wrap and micheal fucks you constantly. don't think i dont know whats going on. i am on to you......and i want in buddy. how bout and tacosnort!
Loughborough University Physics Department received a grant of £250K (about $400K) to investigate the aerodynamics of Toast, and to find out why toast lands butter side down no matter what height you drop it from. Hey investigating bird flight with a wind tunnel sounds quite good.
Modern definition of an expert: Someone who comes from far away with a powerpoint presentation.
Given that this machine recycles its
airflow, it provides a good training
for these birds not to shit during flight.

This is kind of cruel if you think about it, birds pretending to fly, this is kind of like putting a dog on a treadmill and making it walk itself. Maybe it's me but i think that maybe this experiment would work better in the birds natural habitat, because numerous studies have proven time and time again that animals act really funny when placed in captivity. So any data collected would be most likely completely useless.
I hate sigs.
Something else my bird will want for christmass! Everyear fancier toys, and new ways to advertise it. . . .

Don't be fooled! This is all weapon research to be used on the "War against Terrorism". The bird cannon will devastate millions!
Can anyone let me know how exactly a bird in a wind tunnel is considered "new and exciting technology" or "something nerds will like hearing about"? What, have some birds lost the ability to fly and we need to figure out why? I've submitted far more interesting stories than this and they got rejected.
Wind tunnels are really loud no matter the size or speed. Back in my fluid mechanics lab I hated the damn thing because it was nearly impossible to talk to each other, and we ended up wearining hearing protection thru most of the time we spent in there. Don't you think that noise would be dangerous to the animals?

Sir, I have a proposal here for some experiments in our bird wind tunnel. Experiments on top speed, stall speed, and acrobatics.
Sounds interesting. Who's the request from?

I don't see how tilting the tunnel is valid for investigating ascending or descending flight. A little bit, maybe, but it takes more energy to increase your altitude and less to decrease your altitude and that's different than maintaining the same altitude in an air flow that happens to be pointed up or down. But I'm no researcher so maybe it's completely valid.
I was surprised how well-behaved the birds seem to be. When I throw bread out my back door the locals won't even come close to it until I'm well inside with the door shut! I would expect birds to get completely freaked out by this contraption. Pretty cool, wish they had more pics.
Funny he should mention wind tunnels -- for those who are attending Comdex this week, note that there's a vertical wind tunnel only 1000 feet from the Las Vegas convention center.
The wind tunnel is powered by a 1,000 HP electric motor attached to a DC-3 propeller.
It's used to practice sky diving. If you're curious, you can see their website.
I just went Saturday with 4 others. For $45, you get flight instruction, plus about 3 minutes of "air" time. It was a total blast! My sister pocketed wind and ended up shooting up about 15 feet!
Some people never do get the blatent, dry sense of humor that is often quite comical....
Sometimes the caffiene simply doesnt help.
Regarding an earlier post and replies back...
Animal cruelty, by it's plain definition, is when an animal is used for experimentation where the animal is made to suffer some sort of test and physical experiments. I would like to call this experiment on those lines. While it is not traditional animal cruelty, and the birds probably can't tell the difference...that is where the problem really is. I hate the fact that we use animals for any sort of study. Yes the study of birds and other animals have given us such abilities as flight (yeah, humans were MEANT to fly). While that has made communication easier, it has bought on other problems. Let me get back to the main point. The use of animals for any matter of study is a cruel act. They are kept in captivity. After a while they are used to this captivity, and will not be able to return to normal freedom even if set free. Migrating birds, might migrate, but they will return to the lab during their return flight. A lab is no place for a bird or any animal to live. There is no kind moral issue in any type of animal study and experimentation. It is just plain cruel.
These are my morals and opinions. If you have a problem with it...then speak so, oh, and do so in english, because I hate it when some sends flamebait to me that is completely incoherant.
