Ferrari SF-26

Conclusions from studies where they cant even draw a legal wing should be taken with handfuls of salt.

Positive value is downforce. Negative value is lift. Disclaimer: these are models, not the real thing (which is why they have different aero loads when the wing is closed). I believe we can still take the general behaviour associated with the rotation direction.

On the RB version, you see a reduction of downforce when closing. So perhaps it is a small lie that their wing is failing with properly closing, but if the driver closes it a tiny bit late, can experience too much of downforce loss when trying to break and or turn, hence loosing the rear end like Verstappen did...

Sadly I would agree somewhat of the banning these systems, as it relies on (based on rumours) the driver to close them manually, before breaking, hence the smallest of timing error can lead to crashes...
Remember, Ferrari had problems with it in the beginning as drivers complained, so it was delayed several weeks.

1) Both wings experience lift generation during the closing phase. Everything below the yellow line is lift (opposite of downforce).

Max would beg to disagree?

But the conclusions from the study depend on the real world designs replicating the motions from simulation. Red Bull for the moment have an unreliable actuation mechanism, so the theory of having faster pressure recovery is ironically voided if the mechanics fail to close the wing fully: viewtopic.php?p=1349167#p1349167

Kyle also seems to believe you're wrong.

It is not my opinion. It is a CFD simulation. You are free to disagree with it.

True, but my argument was about what caused the crash. Drivers have to manually close these wings, hence small delays can cause huge problems.

The wing physically did not close fully. It was not a delay. It was not an aerodynamic phenomenon. The driver stated this in Silverstone. A mechanical failure.

Viaplay: So what happened there?
Max: "Same as in Austria, rear wing didn't close entirely."

The footage from Austria demonstrated this. viewtopic.php?p=1349167#p1349167

There are several entities producing aero engagement bait (Vanja, Gary Andersen, Kyle Engineers, others) because producing content and followers is valued more than being meticulous and correct. Kyle is reliable/credible, but he missed the simple explanation in this case. The others are not reliable.

To be clear, the only two methods for SLM deactivation are manual button press or automatic with braking, correct? Is there anything stopping the teams from automatically controlling SLM through GPS track position? I assume that's how they coordinate the power mapping and recharge timing for the MGUK system, but don't actually know.

This would allow them to close SLM automatically well ahead of any braking and turning on certain more dangerous corners, but would put another aspect of the vehicle out of the driver's control. Just an idea.

I'm wondering if this mechanical failure is due to the conditions present when closing "late" into a high-speed corner. Aero loads can shift pretty dramatically when under yaw conditions, so maybe closing SLM early on certain corners would solve RBR's problems?
