Red Bull RB9 Renault

[gandharva]

I think the most plausible explanation I've seen is that RBR have installed kers dump resistors in the t-tray.

Guys please stop this. The car simply was set up to low in ride height for FP1's first stint and therefore scraping the ground. If you scrape metal over the asphalt at ~300 km/h it's getting hot! Those thermal cameras show a yellow signature at about 100 C° (because it has to fit the tire temperature window), so nothing unusual here... Btw. those extreme yellow heat signatures have never been seen in the rest of the weekend. Why? RBR corrected the ride height after webbers first stint.

[hollus]

Why would we "stop this"? Learn to disagree, we are here to discuss things. Scraping the tarmac is a plausible source of heat. I for one think that it doesn't quite match. The very bottom is not the hottest part, and heat developed and dissapeared at times when it could fit some sort of electric resistance, under braking for example. But of course in either case, scraping, internal heating or something else, there would be a delay before the visible surfaces warm up. It is complicated.
If anyone has a lenghty thermal video and could post it, it would help a lot.

some news/tweets about MW's RB9 and the heat signature:

Ok, forgive tardy response (busy travel days), talked with Jon Wheatley (Red Bull TM) earlier to follow up on 2 things we saw in Korea. NT

Webber's RB9 monocoque will need changing for Japan as the oil fire damage was sufficiently severe to require a new top section.

The heat signature we noticed around the tea-tray/keel area of Webber's car (via the thermal camera) was from the legality plank front skid

While neither of these little factoids warrant their own hour long special, I always like to make good on my word to follow the story along.

Can they actually build and entirely new car in less than 1 week?

[Saribro]

Assemble an entire car from its component parts, sure. Actually have to start by building a new chassis, no. That's why they have spares.

[stefan_]

As far as I know, spare chassis have a percentage of parts already mounted, so it's not a 100% build-up.

[turbof1]

I always disliked that rule. It was introduced in an attempt to reduce costs, only to have the teams bringing a complete spare car anyway, just divided in hundreds of pieces. The FIA probably never heard of man hours costs, assembly costs and so on.

Any news about the engine actually? Were they able to salvage that?

[Juzh]

Don't they get a free engine when they loose it for reasons out of their control?

theWPTformula made an interesting blogpiece about the vertical vanes:

One of the vertical elements lies roughly in parallel with the endplate, the other (trailling element) is offset by quite an angle, around 45 degrees. I am not entirely sure what they are trying to achieve but I think the vane works in conjunction with the endplates and outboard elements of the wing to project flow around the front tyre more efficiently. Perhaps it does that by separating to the oncoming airflow out into two paths before converging creating a large vortex that helps the outwash of the wing. I am not entirely sure so do not quote me on it! I have not found another explanation, but if I do then I will edit this section.

The illustration isn't correct and therefore the complete analysis.

The drawing could have been more correct, but it has an angle of 45 degrees.

[gandharva]

No, the text says one element has an offset of 45 degrees to the other. While the other one is parallel to the endplate. Both is wrong.

Both elements are more or less parallel to the outwards bend endpart of the endplate and imho are there to push more air away from the front tire. The elements imho are only separated to reduce the higher drag a one piece solution would provide.

I'm pretty sure it's to direct the vortex that goes right over the tyre (the one we saw from the Ferrari pic).

Have we discussed this http://jalopnik.com/red-bull-may-have-i ... 1442585020 and the same but in simpler terms http://grandprix247.com/2013/10/09/are- ... n-control/ .

Is this a new theory as in the using KERS via suspension or is it just rehash of 2 week old news ?

No, they do not.
