Cumulative Windtunnel and CFD Allocations from 2022 to 2024

Post

I decided to calculate the total number of windtunnel runs and CFD items that the top 4 teams were permitted to run by virtue of their WCC positions since 2022. What impact if any do you think this has had?

Of course it has affected the Championship, how much? We'll never know. But if the playing field was level, it would make the Mclaren come back so much harder. The gaps to the midfield and bottom teams would be much bigger too, and perhaps those teams being close is perhaps the best part about it. I think the periods should be shorterned by a lot, like every 2 months or 3 months there should be a revision. MCLs slow starts in the 1st seasons also partly helped them get favourable ATR for 6 months at a stretch.

My other issue with it is how much the general public is unaware of this fact, they think it's a fully merit based sport but it isn't fully. The narrative the media like to portray of MCL resurgence and RB downfall don't so appealing with the caveat of ATR. Ideally this graphic should be shown every so often, I don't think we've seen ever the cumulative windtunnel runs and CFD items ever published by any media.

What is the equivalent of "1 WT run" to spent time in the tunnel?

There's no set conversion factor as it depends on what the objective is for the WT run. The WT run just moves the model through a series of "set points" which are defined by a unique setting of ride height, yaw, and roll. A group of set points is called a "ride map". You can have different ride maps that have more or less set points of the model so the WT runs will take different amounts of time depending on the ride map that is being used for the WT run. With that said, majority of the development runs will use the same ride map. There are other types of studies and baselining that can take place that will take longer than the normal development runs. I can't tell you what that time length is. It's specific to each team.

There's a 2nd parameter in the Wind Tunnel allocation which is the "Wind on Time" which is time when windtunnel is above 5m/s. That wind on time limit can be divided up however which way you like when using your WT run allotment.

Very good. Now add one for wind-on time.

Thank you!
A bit of a shame RBR's new WT is not ready yet. McLaren more or less had the perfect timing.

On the other hand we don't know if a new tunnel has that much of an impact.
