2023 Mercedes-AMG | Petronas F1 Team

Im just confused with the timeline of this supposed event. When did they catch this? Was it before preseason testing began, after the last race or in between ? Its just not clear. Because all the talk of them seeing major gains in the wind tunnel recently is meaningless if they found the problem after that.

I can honestly imagine Italian media getting some info about a small issue with WT models and blowing it completely out of proportion just for the fun of it... So don't take it too much into account. Everybody in Mercedes F1 is certainly more motivated than ever since 2014, so can anyone honestly imagine any person making such an amateurish mistake - no matter the pressure to get everything finished asap? The geometrical model correlation is in the back of the head 110% of the time for the WT team, geometry mismatch just doesn't happen...

Yeah, you’re right, but I did have to smile to myself when I saw this job ad.

Seems to tie in pretty well with the rumours.

25 days holiday seems very low for U.K. working.

No, it’s normal. I think I only have 24 + bank holidays

4.8 weeks is your normal allowance.

I get 21 days plus the bank holiday. So I think it works out at 28 days in total including the bank holidays.

If the advert is 25 days plus bank holidays that’s good, but if it includes then it’s under the allowance

Of all the people in the wind tunnel team, did they fire a graduate/junior model designer?

I don’t think it includes bank holidays.
I wonder how it works with the summer shut down.

How is this even a discussion?

Taking it on face value that this story about incorrectly scaled wind tunnel parts has some merit, and obviously I’ve no idea whether it has or not. But assuming it has, my understanding is that parts have been scaled incorrectly for the wind tunnel models and therefore they are not representative of the full size car?
Presumably no such scaling occurs in the cfd models they use? Does that mean that the results of the wind tunnel tests are fed as inputs into the cfd models so even though the model is “full size” it’s using some incorrect source data and therefore will produce inaccurate results? Effectively masking the wind tunnel error?

Its not the scale that is problem. The scale is a given. The tolerances werw the issue they said.

If this is a whole department that screwed up, knew they screwed up and said nothing? Then you'd expect all those directly involved to be fired. Mercedes have other job adverts up, including one for a senior structural analysis engineer.

Are wind tunnel models of the underfloor scaled down linearly?

Since underfloor downforce is non-linear with ride height, I can imagine that you need to account for this when scaling down the floor, and have some modifiers there for the road to floor distance of the various elements. That would make the scaling itself a complex task, and getting it right not straightforward.

[PlatinumZealot]

Yes the entire car is built to scale. All parts are scaled the same.

This problem has nothing to do with scaling. All teams use as big a scale as they can legally use. 60%.

You could have a badly manufactured wind tunnel part that is the right scale but the fit and finish, and perhaps the flexibilty too is bad. Now that will impact the aerodyamics!

[PhillipM]

I don't think that's right at all, many parts aren't built to scale, or they didn't used to be when I used to have access to Manor, a lot of scaled parts are modified to account for predicted differences at wind tunnel scale vs car scale. Things don't work the same just because you made everything scaled the same.
It's part of why correlation between not just the wind tunnel and the CFD work, but also the full scale results at the track, are so tricky.
