Yes. Starting in reverse gear would be surprising enough.Shrek wrote:To me it looks like USF1 is playing some poker, they're misleading the followers so when they do race, they'll surprise everybody
They dont need to build 60% scale models for wind-tunnel testing - everything will be built full size.cooper-climax wrote:Reading the article, it looks like the visit took place in September.
"When I visited the workshops in mid-September, I saw "six weeks worth of flat-out, gutting the building and slowly moving into the officers (sic.),"
Also, this line confused me. I can't think what a seven-post rig has to do with models?
"Thanks to CFD, the 7-post and 3-D imaging, no model shop is needed and one is not planned."
That confused me, I thought the cost cutting measures were that wind tunnel test models had to be 60% so teams using smaller tunnels didn't have the expense of building full sized tunnels?djos wrote:They dont need to build 60% scale models for wind-tunnel testing - everything will be built full size.
Yeah but cant the cost of the full size tunnels be offset against the wasted resources a 60% scale model uses (or are there any for sale on ebay? ).richard_leeds wrote:That confused me, I thought the cost cutting measures were that wind tunnel test models had to be 60% so teams using smaller tunnels didn't have the expense of building full sized tunnels?djos wrote:They dont need to build 60% scale models for wind-tunnel testing - everything will be built full size.
I think you are very much mistaken there. As the cross section goes with the square of the width you will find that building and power cost for tunnels will also go up by a higher than linear function.gibells wrote:The cost of a full scale wind tunnel cannot be that much greater than a 60% one.
Yup, its an embarrassingly nationalistic piece.cooper-climax wrote:The next instalment of Peter's blog is on the site. http://www.usgpe.com/blog.html
Quite interesting.
Firstly, it's clear that PW has given up on a world audience, and is writing for America. "Don't go to Europe, it's cold and the people are lazy"
I think its not just the cost of the tunnel, but also to diffuse a wind tunnel arms race. The teams operating at 100% will get richer data than those at 60%. That would have forced the other teams to abandon their 60% tunnels and build new 100% tunnels.WhiteBlue wrote:I think you are very much mistaken there.

Because it is an existing wind tunnel nearby that they have contracted to use during the season.richard_leeds wrote:The 60% rule allows teams to continue using existing tunnel facilities without disadvantage.
So why are USF1 talking of running the full car in a tunnel if there is a 60% rule?
Again, the FIA only allows for six days, at four hours each, of full-scale wind tunnel testing over the whole year.jddh1 wrote:If you already have a tunnel that can accommodate the full model, I don't see why not.
