Red Bull RB6

[Remote_Access]

I posted this pic from a video from the China race, a few pages back, before Monaco last week. It looks to me that there are (might be) inlets in the area below the lower control arm mounts and above the center splitter area. Visually I'm speaking of the area below the control arm pivots and above the ride height sensor. They appear to branch into the radiator inlet areas, 1 per side. I'm not talking about the barge boards though these inlets could have been fabricated as add ons to the chassis, thus not requiring any crash testing. What if this is the location where they are going to drive the blown wing?

Certainly we can debate whether there are inlets there but it looks pretty much like that to me and this part of the car is almost never seen .. it's sure to be a high pressure area though and perhaps ideal for routing back via the side pods to the engine cover .. just speculation on my part though .. can you "overblow" the wing with too much pressure or would, as I suspect, higher pressure provide a better effect?

Interesting but I think what you'll find is that is a flat surface on the underside of the tub. The area above that is clearly rounded, and it then flattens after the rear control arm mounting point. It looks dark as most of the light it reflects is from directly beneath the car, ie shadow.

Its emerging that changes to the the Red Bull diffuser were successfully protested at Monaco. I will try to get more tech info on the issue

"We had to run a version without those [diffuser] wings and found that it was even better than before," said Horner.

Somehow I think it was another drawing off the attention or even a mean trick. RBR says "look what we've got here" and though MCL kept an eye on the diffusor they could not see what's REALLY going on there, because they were razzle-dazzled by that silly winglets.

Hamilton already knows that: "it just takes the Mickey"

Anyways, The buoyancy of the hot gas delays the transition to turbulence in the diffuser and this can enable RB6 to have higher expansion. I got this idea from a video
I came across some ancient videos which proved interesting.

watch the turbulence video.almost towards the end there is a part where in a channel they demonstrate if the hotter fluid is made to flow above the colder fluid it delays turbulence.

I think this is the most crucial part of the RB6 performance.

That seems to be a pretty good explanation. What I think about is: can they use this principle in 2011 when the DD is banned?

Red Bull just announced that Vettel had a dodgy chassis and that's why he couldn't keep up with Webber. The car was so imbalanced. Or so they say.

if it is possible to create a slit and channel the exhaust gas into the main diffuser it could be applied next year too. But, Im not too sure about the regulation regarding if it is allowable to have a slit.
But hope other teams catch up and get this on their cars too . It will need a total revamp of the rear end... and like last year brawn i guess this is next big thing ev1 will have to impliment and fast if they hav a hope of catching RB6.

I don't think that diffuser slot is the RedBull's secret to speed, it's easy, too easy.. I even think the Renault uses something similar but it's hard to see because of all the blackness at the back of the Renault.

The secret to the RedBull is the whole shape of the car tuned to perfection from all angles. Little appendages here and there by other teas are not enough; the basic shape of the Redbull along with it's suspension tuning is just perfection.

Then why is STR slow and -with a similar shape- why is Virgin? sorry

Did anyone get to the bottom of the possible pivoting of the rear wing assembly at speed? I found it very interesting how there were obvious radial joints at the base and on the fin but from what I've seen it wasn't really explained.

The shape of the Torro rosso's body is pretty good as you say. Maybe their diffuser and Front splitter just sucks in terms of DF, and maybe even the mechanicals are nowhere as good.

Working with the body, the redbull front wing is also something worth noting. Not just in terms of downforce but in the way the front wing influences the air flow over and under the body because judging by the simplicity of the Ferrari wing, we can deduce that the front wing definitely is not the limiting factor for downforce in these present cars. I think the front wing is one of those parts it is easy to get down-force from it if you want it, but the secondary function of the front wing as a flow conditioner for the parts downstream is the tricky part. All these things seem to be working in perfect harmony around the RedBull body.

hey, Im new to F1technical. my 1st post.
I think im late on the discussion on the exhaust gas being used in the diffuser.

Thanks for the interesting link, f1ssk...

Do you not think that RBR exhaust layout might be an application of the Coanda effect? (See, for an example, the start of the film "Pressure Fluids & Fluid Acceleration".)

howdy guy's can we have some pic's of the rear gearbox with the pull rod setup please

Oh and while you're at it some pics of the diffuser inlets would be quite timely as well ..
