Wind Tunnel

[ultramrw21]

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

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

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.
