Renault R31

[Blackout]

What do you think of this ?

[Mandrake]

I guess the Beam wing is stabilised on the crash structure, nothing more than that. Or do you talk about the heat stickers?

[The Thorn]

Not only the stickers there, but also at the outside of the rearwing-endplate. Maybe they have re-routed the exhausts like Red-Bull?

The temp stickers have been discussed for a while now, even with the FEE there will be exhaust gases flowing through the ebd area. That's measured with the temp stickers.

I imagine that the temp stickers that are highlighted are measuring heat dissipation from the diff. As for the other locations, why not stick probe here and there, it's testing. Just because they stuck some temp sensors there doesn't mean they have a problem, just that they have reason to be curious ..

[netoperek]

I wouldn't be suprised if some of these wouldn't be just temp stickers. MFC patches are about the same size and can give some valuable real time info on strains. Check top-left sticker and green spot to its right on blackouts image - could be where dc cables go

[segedunum]

The exhaust gases from an F1 engine will certainly be hot enough, and a deal more concentrated, for the same effect to happen but to an even more marked degree.

Not really. You can't just blow hot gas into more than a force 9 gale and expect that gas to heat up the environment and maintain its temperature itself. We don't know enough yet about what Renault are trying to achieve with it.

[Blackout]

I wanted to ask why are the stickers I highlighted, partly black/showing a different value unlike all the others ?

[segedunum]

I have to say, I've been very, very impressed with Renault.

The front wing is very well developed and has clearly carried on from last season. You compare their wing to something like that from Mercedes and it looks like it's come from another planet. Not sure what their exhausts are doing, but the fact that they've turned up to the tests with them and kept them on is a good sign. Their packaging is also very well done. They have a very clear and unimpeded path over their sidepods and engine cover.

And the exhausts are not the only mystery in this R31. The sidepods outlets are the second mystery

The Williams has the same mystery outlets. Damn hard to figure out how they are venting the radiators .. maybe all the heat sensors give a clue. I've been speculating as to whether they are mixing free flow air from the radiator entry with radiator exhaust to keep the airspeed up and then dumping in a low vent over the diffuser box to charge the airflow over the diffuser. I have no evidence but those radiators have to vent somewhere and these two cars a "non obvious" in how they accomplish that. One thing's for certain .. It's not for no reason ..

[segedunum]

I love the little details as well. Look at the outer part of the sidepod and how it's curved inwards to channel air there.

The sidepod outlets are a mystery. They could be channeling that heat somewhere somehow. We can probably make an assumption that if it's not being vented it's being used somewhere......

[dren]

The side pod exits are low and wide across the back.

[Blackout]

We know where the outlets are, we started discussing about them on page 42 with this post:
viewtopic.php?p=223595#p223595

but they remain quite misterious...
AbbaleRacing77, Lindz and I think these outlets are designed to blow the hot air just above the diffuser, an air accelerated inside the sidepods thanks to a Venturi effect.

Temperature stickers are available in widely different ranges, unless you can see the numbers it's not always correct to assume they are all from the same range.

If you want accuracy, you'd put a high range sticker in the very hot bits, and a lower range in the cooler bits ... in early running, if you are not sure what temp to expect and don't want to waste laps only to see a full-scale black, or an under-scale unchanged sensor, you may choose to use a couple of stickers from overlapping or contiguous ranges placed right beside each other.
