Red Bull RB8 Renault

On the face of it, it's not. Unless they found a loophole. But thus far, it seems like only speculation teams are using this.

Yep! I've been saying that since the new exhaust came out.

Looking at this picture (again):

Image

You can see how the exhaust hits the vane and gets directed down into the notch and toward the tire, while the air coming from the outside of the vane (which includes up to half of the exhaust) goes up and over the vane, crossing over the lower exhaust flow. The combination of these two creates the vortex.

Odd one out: Only one of these has a cutout in the floor has the sole intent of re-ingesting the exhaust under the floor...
Could be the difference between a legal system and a non compliant one(at least within the intent of the rules).

The exhaust flow he has is what Mercedes is doing, not what Mclaren, Ferrari (initially), and Sauber are doing. nsmikle did computer simulation on the Mclaren flow and it most certainly is blowing the side skirts of the diffuser.

If you "enhance" the pictures of the Red Bull rear wing you can see they are reflections of the drive shaft and other rear components.
No Anderson is clearly talking about the rear wing.--> http://img545.imageshack.us/img545/3898 ... detail.jpg

As for the exhaust, maybe you haven't read this entire thread, or even last page, because I specifically said the exhaust was going to the floor at low speed just like McLaren.
I was also clearly talking about the rear wing. That's why I said rear wing when I was talking about the rear wing. They are not slots, they are reflections.


I wasn't refering to anything you were saying, I was talking about Gary Anderson's article you posted.

What's the chance of some of the or the majority of the exhaust being sucked through the underpass?

Not sure if that was discussed already or not. What are these 2 new slots for, that are located in the new design, just above the diffusor floor, part of the 2 new, black carbon material blocks, which are as well housing the exhaust slots further upfront and up.
You guys know which ones I mean?

As the 'cannon' ball exit is now a lot narrower in this layout version, does the hot air exit there onto the diffusor to blow the same? Maybe something to do as well with the mail box slot in the nose?

thanks,

Not very good. The exhaust wouldn't make that tight of a bend, especially at speed.

Has been discussed already. There are easier ways to manage that route.

Has been discussed already. If I correctly understand you mean the tunnel under the new exhaust path to route the air from the lower sidepods to the back center of the car where the engine starter hole waits for some food (see pictures with drawings above an pages before).

IMO chance = 100%. Majority.
More at higher speeds.

Most definetly reflections on the rear wing.

I'm quite amazed Autosport of all people have gone to the trouble of printing a sketch quite obviously based on here say.

I say very little exhaust flow makes it to the diffuser side/edge. Look how slow the flow is about 150 mm from the exhaust tip. At this point at about 30-40 m/s it is highly influenced by the direction of body flow which is say at 60 m/s on average. The body flow never gets slower than 30 m/s at most tracks. The effluence of the body flow is additive as the exhaust flows out form the tip.

Remember, in this illustration the exhaust is much closer to the diffuser than RB.

It´s the latest package, look at the bargeboard wing.
The latest RB8 doesnt have the extra layer of heat shield over the rear suspension arm In this photo you can clearly see that on the rear wishbone, unless it is something else..

Yeah, the bargeboard wing looks like the old one to me.
