Wind Tunnel

[roboticsguy1988]

Well, so there is one at Purdue, but it is broken from what i understand????

Well you can do what the guys from spaceship one did and mount the thing onto the front of a suv.

LOL, some how that doesn't sound........oh whats the word, um...............efficient. lol.

How fast does the air need to be traveling for you to collect the data you need?
I built a small scale wind tunnel using a house fan, its max speed is about 20-25 mph. But you probably need something with some more power.

I think 25mph would be pretty slow , although it could work. IDK, what do you think Wayne???

that means you need a couple more fans. but lotsa small fans will proly not make a smooth flow. itll have so much turbulence. cheapest way is prolly

except we all know suvs have bad aerodynamics so you want a loooong pole or sumthing to keep it away from the car or. get a ferrari or sumthing

wire up all the included muffin fans in series~ and you can blow your robot to your regional in 1.5335 nanoseconds

LOL, hey theres an idea, everyone charge the batterys , LOL.

There is one at Rose-Hulman in Terre Haute (or at least there was still one the last time I was on campus a couple years ago), but that's probably farther than you want to have to go.

How big a test sample and what wind speed is required will have a major bearing on finding a tunnel. You can test a scale model, it just will require an appropriate increase in wind speed.

Maybe it wasn't an SUV but all I know is that these guys went into space using a car as a windtunnel so it has to work.

If i remember correctly the SpaceShipOne team mounted the model to the front of a truck to test its drag. Id be pretty nervous to compete against a FIRST team that had to test the drag of their bot.

[Cyberguy34000]

I think that they need a wind tunnel because they're trying to actually build a wall-bot

yea that was the 1st thign that poped into my mind. i still jsut abotu died seeing a thread with this name

yes there are rules aginst hovercrafts

but how would you get it to fly antway

[Whiteviper]

wonder if this is just to scare people, it kinda made me wonder what was possible but after reading the rules again I'm not that worried any more.
