Wind Tunnel calibration; Could it be that simple?

Honda designed and has developed its disastrous RA107 single seater with an incompetent wind tunnel, according to team driver and formula one veteran Rubens Barrichello.
Just prior to the recent Hungarian grand prix, where the Brazilian and his teammate Jenson Button embarrassingly languished as backmarkers, Barrichello travelled to the Japanese team's Brackley base in the UK.
He said he wanted to meet Honda's two new aerodynamic acquisitions; Williams' Loic Bigois and John Owen, who came from BMW.
"We had a very long talk and they made a great impression," Barrichello, who is 35, said.
"I heard from them exactly what I expected to.
"They believe that our wind tunnel's calibration is wrong and because of that everything that has been developed has not been effective.
"We will have to change many things -- even parts of the structure inside the tunnel. It will be about a month until we are able to see changes."


This would be good news for Honda if it was problems with the Wind tunnel...much easier to fix than unknown problems with a dud car concept, and it would bode well then for dramatic improvements in next years car design if it does turn out to be the case <thumbsup>

It's definitely not engine-related as Aguri have done well with the same engine. It will either be a hit or miss situation if they can manage to adjust this - they will either start improving, or if it's nothing to do with the wind tunnel then they are in deep trouble because they will be at a loss

I hope they can fix it. We want to see as much teams fighting at the front as possible

It's a shame they found no benefit with those elephant wings, had they been on the car for a race, they would have been an even bigger laughing stock.

Wind tunnel miscalibrations can result in abberant designs and ineffectual constructions, no doubt about it. I just wonder how this can happen.

Given time, you put an old shape in the tunnel and use that as the standard from which to calibrate the tunnel. You have real data and you have calculated data. You compare the results from the real data to your tunnel data. The comparison should rveal the differencs between your actual quantitative analysis and the abstract analysis you expect from computation.

Given enough actual data inputs to the standard calibration, the abstract tunnel data should be reliable.

However, if you have a new shape and a new tunnel, you have no standard to base the results on. Two variables in an exercise invalidate the exercise and produce unreliable results.

Honda - Guilty!

Didn't Renault blame their poor performance at least partly on this?

Is this the same wind tunnel Honda put out of action earlier in the season by forgetting to tie the car down?
