Aerodynamics / Aerodynamic Cost / Aero parts

Crazy that they're unused considering what they must cost. Presumably they still work?

I assume everything would still work if you knew how to fire it up. The test cells all look fairly fresh so I think all 3 tunnels were in use.

So, what would it take to get those wind tunnels running and calibrated again?

Everything is disconnected and the control system, whatever that looks like, is missing. The motor is something like 500-1000hp so I can’t just plug it into the mains and bang the power on one lunchtime!

Presumably the non-F1 tunnels were for aeronautical stuff?

Aviation originally, then it was mostly marine. After the race teams left, they were used by a company for aero testing buildings and urban layouts. They had a big workshop down the side and from time to time you’d see one of their models outside, which was like a miniature section of a town or city.

I have a feeling that's still a viable option for low speed fixed-pitch applications.

Yeah, there’s no reason why not. As long as it’s tested and still in date, it’s probably better to have a wooden prop explode than something like an aluminium blade flying through the side of the tunnel!
