Williams FW34 Renault

[Gridlock]

"Optimess" (and a laser warning symbol) on the yellow label: http://www.elag.com/

The tube visible in the rear of the floor will be the starter motor hole? Interesting rectangular slot surrounding it? Plenty of struts/braces around there for sure.

Is that laser somehow connected with wheel slip sensor, or what is its purpose?

There does appear to be a sensor mounted above the tea tray

[Mandrake]

The chassis just looks dusty, not burnt anywhere, just needs a good cleaning I suppose ^^

[MIKEY_!]

interesting slot on the rear wing endplate, never seen that sort of thing before. Whats the benefit? Seems to far from either the rear wing or the beam wing to be specifically for their benefit. Maybe it's to help stop air building up in front of the tires.

My thinking would be that it's directing some air flowing round the outside of the rear wing inwards, so that it'll be driven up by the rear wing, further increasing the speed under the wing, and improving its efficiency. But as we all know, armchair aero is generally a disaster.

You think there might be an armchair in the HRT design office??

I was wondering whether it could act like a slotted wing or leading edge flap like on an aircraft and reduce separation (if any occurs on the inside surface of the end plates), particularly at higher yaw angles.

So you are implying that the slot works in the corners then? Makes sense.

That's what I had in mind

My only query is how turbulent is the flow in this area? I imagine quite!

I was curious whether less turbulent flow from the outside of the wing flowing through the slot could encourage attached flow along the inside of the end plate and tidy up flow?

Williams have modified their exhaust to incorporate radiator cooling into the flow at the rear.

Good shot of the rear end, from @tgruener on Twitter:

It's very simple (I think), these slots add energy to the upper rearwing section. The idea is smart because, the high pressure area above the rear tyres (where the energy is related to drag directly)can be re-used, in a more effecient way.

I dont understand, if the new is the small image they didnt race that as stated, or rather they have never raced that is in the small picture, so what is gary on about?

The small image is the old exhaust. The large picture is the new style as it also functions as the radiator cooling exit.

Yes they have raced the small image



Edit: it's real old I know, but it's their first real technical piece on Williams so they're starting from the beginning all the way til now.

Jason: Firstly it's wrong that the exhaust solution is new, they only ran the oval outlets at Melbourne as far as I'm aware. However I do think they perhaps opened up the sidepod exits slightly. Secondly has Gary Anderson been reading my blog? http://somersf1.blogspot.co.uk/2012/05/ ... o-top.html almost word for word the comments I wrote just after the race on Monday LOL

'The FW34's side pods end quite abruptly with the exhausts exiting along with the airflow coming through the side pods in order to combine these flows energizing the latter. This allows for a much broader flow to exit toward the rear of the car much further forward than if it were to exit from an engine cover cooling slot.This flow enables the diffuser to work more effectively further forward on the car.'

If you check back over the smoking car of Pastor's from China they ran with the sidepod exits in the same place as the exhaust
