Red Bull RB9 Renault

Hey guys, so good to be back on track again (even though the off-season didn't feel too long this time). Nevertheless some of you seem to be so that you start to discuss the 2012 parts.

The RB9 is the 4th evolution of the RB5 and is just refined. No surprise considering the new regs not until 2014. There are just small (visible) changes which they surely would have done in 2012 had there not been the consequence of a new homologation process (narrower sidepods, Sauberian nose slit).

The tunnel thing is pretty much the same thing as last year and was well elaborated:

"The larger forward ducts simply vent either side of the gearbox"

"The smaller ducts feed back into the diffuser’s boat tail to blow the starter motor hole"

Thx 2 Scarbs' blog

As mentioned there are few changes such as the Sauberian slit behind the nose and the thinner radiator cooling inlets. This should be a solution as good as Sauber's, because the air flow is well ducted around the round sidepods.

We can be sure there will be further updates at the second or third test sessions as Red Bull have never shown their hands at this early stage and they surely first collect data in order to compare them to the ones of the RB8.

So calm down, people!

Nothing to do with anything, but 'sauberian'... most..awesome.. word.. ever.. haha!

Although they haven't blown the starter motor hole directly for a while. And as such we don't fully know whether the tunnel splits anymore.

Not neccessarily. Yes it is designed to be in the centre of the car, but if the rear springing is softer than the front, the attitude of the car will alter as the weight decreases.

but isnt is desirable to run the rear softer for better acceleration? and practically every type of race cars run that way?

Different cars run with different softness. It is totally possible that Red Bull run softer than others, knowing the effect it wil have on rake as the fuel load lightens

I think that much of the reason for the tunnel is to trim away turbulence ahead of the exhaust pattern to the floor. This would vastly help the exhaust flow to be consistent. The RB is the only car I have seen to put down a distinct exhaust pattern on it's bodywork and floor ..

Tacky to reply to my own post but I would like to hear what you guys think about this ..

Quick question about the front wing, what are the funny looking attachments to the top of the wing, look like a small tube with a brass ring, trying to post images but an only new at this.

Is it possible (Legally) they are dumping hot air from the radiators into the larger tunnel?

After carefully looking at all the RBR pictures, I think RBR has some sort of DRD system on board and working since day one in Jerez. The blow off holes are exactly the same than last year, but now it's somehow passively triggert via their swan neck mounting. At the attached picture you can clearly see the blow off hole (red circle). Flow viz on left side of beam wing also is bend inwards which imho indicates that the DRD is already working. What do you think?



/edit

This could be the DRD intake/trigger

[BreezyRacer]

Well Grandharva, that flo viz pic certainly shows a much different pattern than earlier pics, which had the flo viz nicely even across the beam wing underside. You might be onto something there .. where do you think the charge is coming from? Perhaps inside the airbox? That way the method that Lotus is using would produce a similar response as airbox pressure builds during closed exhausts.

So you saying that DRS + DRD give Red Bull maximum of 290 km/h in speed trap in Jerez. I would be very concerned if I was a fan of this team how much would they have without DRS use in Jerez, 270? If they come in Barcelona with that speed they can say goodbye and salute for 2014.

Hey,

at first I'm new to this board. Was reading it for two years now and finaly decided to join in. So hello everyone!

In this pic you can see that the beamwing just has a slit through it. it's the same position as in the flowviz picture



But at all, i think this could be a great idea to use the drd. would it be legal?
