Brake Ducts, Tire Cooling, and beyond

[SB15]

Really? What have they told you?

They don't need to tell me or anyone anything. The whole reason they designed the tyre cooling was to keep the brakes in working order. Unless the brakes are in better control of their temperature by itself next year, this will be a headache for them.

More than likely, after Red Bull pitched all of those tyre cooling solutions to the FIA, 5 if I recall rightly, 4 were categorically rebuffed, 1 idea was left slightly ajar so the FIA have felt the need to completely close off any ambiguity.

Mclaren will just carry on cooling their tyres and breaks down with the airflow created by driving the car. I just know it.

I don’t think they will or maybe they might who knows. Judging by the way the race reported it, it looks like the FIA is cracking down on whatever the McLaren is doing to the tyres and brakes.

Which is a shame because it is a very creative idea that extremely minimized overheating of the brakes and that also has a profound effect on tyre temperature.

So I feel the FIA just gave away their secret, and no one seems to notice?

"new wording ensures suspension fairings must now be internally sealed to prevent airflow manipulation"

This line right here! Or is this related to one of Red Bulls inquiries? If it's not, then could this be the silver bullet? If so, would other teams be in time to develop it for this season? Would it even be worth to so?

I don't think any lever can supply or remove the required volume of air given its size. Plus, the loads that the suspension endures are large enough that someone decided to make holes in them.

I guess they dont have to be physically strong enough. There is a chance that the suspension fairings are just 'covers' for stronger components rather than being fully carbon fibre. Teams were already using fairings to direct airflow around the front of the car so allowing air to travel through them should be easy enough.

Could also use things like hollow driveshafts to direct air into the centre of the hub/drive flanges.

Quick google search led me back to this forum with quality pics of some suspension arms.

These photos clearly show that the main body of the lever has no void, and the pads around it serve as a cover for the wires. I seriously doubt that such a small space can be used for anything else.

Vanja was a little curious iirc about the suspension arms being used for cooling too I think based a little on some Stella comments.

I'm not sure if you understand that these are more than 10 years old, and not the Mclaren suspension arms?

[Rikhart]

Has anyone mentioned before that the trick could be some air is getting rammed via the suspension fairings, entering the brake tin, and exiting via those carbon fibre openings they have?

Something like this:

The rear suspension on most now have one arm "coincidental" if that's the right descriptor, with the drive shaft itself. The two components are then covered with a unitary sheath such that we don't see the drive shaft, that running in a void of the sheath. There's most definitely the possibility of space within that arrangement for unimpeded flow.

The drive shaft itself, in conventional terms of hollow/flow possibility, much less likely. At inner and outer end its attenuated with CV joints to produce angulation over suspension movement. Usually that will produce no real through path to facilitate any flow capacity. There's ordinarily drive through arc and ball "tracks" to provide that "constant" part of the CV component rather than shaft speed variables across the drive coupling and not produce a wave form oscillation during changes.
