New Wind Tunnel (Cincinnati)

[cfg83]

metcalfmj -

Would your tunnel work with a 1:18 scale car model ? Think die-cast :



If yes, and if I mailed you the model, how much would it cost to do a test? You can PM me if you want. I would also pay to have the model shipped back to me.

Bill, you are correct -- the MIT Wright Brothers Wind Tunnel is the largest civilian pressurized wind tunnel. I think they can go up to 2 atmospheres? And the testing section is a 7' x 10' oval:

I would love to test CarBEN EV there but they are busy until late summer. This is why I was inquiring about this new wind tunnel.

That seems like a pretty big test section. Cool.

A relevant quote for the Carben
"For example, the Reynolds number of 1/4-scale models tested at flight velocities at atmospheric pressure would be too low by a factor of 4. Because the Reynolds number is also proportional to air density, a solution to the problem could be to test 1/4-scale models at a pressure of 4 atmospheres. The Reynolds number would then be the same in the wind tunnel tests and actual full-scale flights."

Looks like the gubmint gots one that goes to 10 atm...
Low-Turbulence Pressure Tunnel
The Langley Low-Turbulence Pressure Tunnel (LTPT) is a single return, closed-circuit tunnel that can operate from 1 to 10 atmospheres. The LTPT has been used for tests of high-lift airfoils, basic research, and theory validation. LTPT's capabilities of low disturbance, variable density tests and high-lift, multielement airfoil tests at Mach numbers from 0.05 to 0.5 and Reynolds numbers from 0.4 x 106 to 15 x 106 per foot are unique in the world. This tunnel is ideal for preliminary aerodynamic configuration screening because of low operational cost and relatively inexpensive models.

Interesting stuff.
