Williams FW32 Cosworth

[tomazy]

It's weird that picture, which day was that photo taken? I can't find a similar picture. There is this one:

I found one particulary interesting picture from Jerez testing. The rear wing on this picture has a white stip acros, and what looks like a gap in the middle of that strip? This is strange, becouse 3 part rear wings aren't legal?

What do you guys think?

Regarding the big picture, it looks more like a long main element with a white strip, followed by a short second element. My feeling is, that if you could see daylight through it then it couldn't be a blown flap. I think you can definitely see daylight through the small, high, slit. Also, note that you can see the normal williams 'slot' in the flap element above the jack man's head. So I'd be surprised if this was a blowing slot in addition to the normal slot.

So I reckon, not blown flap but long main element with stripe. High downforce setup perhaps?

EDIT: Although, if you at the end plate it looks like there is light coming through what I thought was a white stripe. However, I reckon this is just a reflection of the white paint rather than light getting through.

Yes, it is strange. It might be a narrow whiter strip on the not so white strip, but if you look closer at the bottom edge of the narrow strip, there is something that seems to be the edge of the wing element. But you are right, if it is day light comeing through it cant be the same principle as BMW or mclaren.

I also didnt come across any other similar pictures

Tomazy,

Scarbs agrees with you;

And gives you the credit for noticing

Scarbs has just posted that the FW32 featured sidepod intake restricters at Jerez as they possibly feel that the Cosworth is taking less to cool.

I saw this in the first tests in Jerez.

Isn't it the same tool McLaren is using to prevent flow separation in the upper element?

Scarbs has a photo from today of restricted cooling for the cosworth, it looks like it is cooler than they first thought!



Would anyone know why they have routed more air under the side pods, by blocking the bottom of the air inlet rather than the top or side? Can they better utilise the additonal flow at the back of the car?

WOW!

this looks interesting..... is it really?? then why the Lotus was having glowing exhausts at last test and was on fire? maybe not enough cooling arrangement by the team themselves???

[axle]

They would indeed block off the lower section to force more air around the sidepods to the back of the car. This will reduce drag and potentially improve the performance of the diffuser.

Lotus's issue doesn't have to be engine related directly...the exhausts will glow on all the cars...setting fire to the car could have been an installation issue, small oil leak etc.

i think the fire was due to a fuel pump issue with the cosworth engine not anything to do with lotus themselves?

New sidepod inlets for chassis02

Wow, they've really closed them off. Cosworth runs pretty cold then, I guess. This is backed up by the rear of the car where the slots and openings of the Mercedes or Renault are not so apparent. What does this mean in performance terms? Is a cooler engine more efficient?

I believe a cooler engine allows slighty more dense fuel/air mixture which carries more oxygen and more fuel to the combustion chamber than a warm mixture would. Thus more power.

[Blackout]

Yes
And heat is energy. So a cooler engine looses less energy

[King Six]

Also less drag if the pods don't need to open so much

side pod inlets now resemble Mclaren and Virgin rectangular inlets.
