Sauber C31 Ferrari

Ah. I took your use of the word setup as in car setup/tuning/optimizations

[MIKEY_!]

Fair enough really, I wasn't being very clear.

That air outlet could be taking air from somewhere on the front wing to maintain laminar flow there. Entirely conjection by me.

[MIKEY_!]

That could be allowed. I think it is more likely an exit for the cooling usually located in the nose. However they are 'oversupplying' the cooling system to get enough air behind that broken nose to prevent separation.

Shakedown days are like tests, its filming days which have restrictions.

[raymondu999]

not the same restrictions though

[horse]

I think we could have three things here or combination:

1. drag reduction. higher pressure Air from under the nose or from the cockpit will fill the low pressure gap.

2. The signal hole for the front wing f-duct.

3. Just a simple device to create air circulation to cool the driver.

Personally, I think these two combined and it's very clever too, a much better concept that the RB8's CD slot.

So the wake of the kink will provide a nice little pull to bring the air through the cockpit, whilst that same air will reduce the impact of that wake. It will also cause a little lift, where I said it would cause DF before, as there will be a positive circulation set up through and above the cockpit.

New exhaust layout for testing day 3 (via Auto-Motor-und-Sport.de):

[shelly]

Interesting features:
-exhaust position
-sidepod not undercut but touching the external edge of the floor instead
-large use of spread tow carbon

Question re:

large use of spread tow carbon

. Is 'spread tow carbon' stronger than 'regular'* carbon?

*regular carbon being of finer strands.

(Sorry, not technical)

[KevlarUSA]

I believe I've read on this forum that spread tow isn't as strong but it's easier to form into complex shapes.

If you are referring to the chequer board carbon, it is simply a hybrid if ud carbon running at 0 degrees and 90 degrees, often used on bodywork as it is stiff and light but its not very strong. Oh it is definitely not easier to form in to complex shapes regular ud, 2x2t or a 5h material would be much nicer.

It's lighter for the same strength in most cases as well and is ideal for a "skin".

Yes, but there are different weaves of 0/90 carbon. I'm no expert, but spread tow carbon seems to have a larger checker pattern than the rest of the 0/90 used throughout the car.
