F1 » Loss of wind tunnel not ideal, admits Ferrari


Ferrari says that it is focussing on aerodynamic developments for its new car, despite currently being without a wind tunnel at its F1 headquarters in Maranello.

I wish they would ban full size wind tunnels, and use perhaps 1/5th scale models at a common wind tunnel that all teams must use.
This would reduce costs greatly and allow low budget teams, the chance to be closer to the front.

*There are also restrictions on wind tunnel testing. The scale models used may be no larger than 60% & speeds are limited to 50 m/s. However teams are permitted to substitute one of their one day aerodynamic tests for four hours of wind-on testing in a full scale wind tunnel to be carried out in a single twenty four hour period.*
50m/s = 180km/h

Full sized wind tunnels are very expensive, both to build, and to operate. A much smaller one would be much much cheaper, and any exhaust effects would be almost impossible to factor into the design.

Any idea what problems they're having with the tunnel? I presume it's related to the age / declining accuracy of the data aquisition equipment and not the physical structure or air-moving machinery...yes?

Also, does anyone know if the 180 kph speed restriction is on the scale speed or actual air speed in the tunnel?

Thanks.

One other question for you, RobG - I believe that a full-scale tunnel is quite expensive to build given equipment cost differences and to operate from a power standpoint, but is it really that significantly more expensive than a 60% scale tunnel?

It would seem a majority of the cost is going to be tied up in aquiring the engineers to calibrate / operate / maintain the equipment, run the tests and interpret the data. You'd still need this same technical expertise for a scale tunnel.

Sounds from your posts like you might have some experience with these matters.
