2012 Red Bull RB8

[Hampus Andersson]

Notice they are back with the high rake now.. and that probably means the flexing wing will be back in it´s most extreme form.

Found an answer to my question, i think the starter hole is here:

That where they are trying to aim some of the extra airflow, the rest is gonna hit the top of the diffuser. amirite?

 

[Hampus Andersson]

They are trying to seal of the diffuser as best they can, how exactly they go about i have no idea.

 

[Hampus Andersson]

They are trying to get some of the gases under the car,

You can see the hole here, rectangle shaped.

That hole exits here, below yellow stripe.

Some gases will pass over and on to the sides of the diffuser, and some will trickle into that hole.

 

[Kennett Ylitalo]

That is a real loophole.

 

[GAIAjohan]

Would it be hard for other teams to implement?
Just asking cuz I'm tired of RBR and Vettel leading the pack..

 

[Kennett Ylitalo]

It might be, it all depends what happens before the air gets to that point, if the car is shaped very differently then i think it's gonna be very hard. But if the overall concept is closer to RBR, i wouldn't be surprised if it gets copied soon.

[Hampus Andersson]

Started melting a tiny bit and we can now see that some of the gases appears to be trickle down on the side,

 

[Hampus Andersson]

Illegal wing they say at F1Technical,

Looks like it´s broken..

 

[Eric Parker]

not all things going to plan?

 

[Hampus Andersson]

Not sure really. It could be that the car with the new exhaust has been over engineered so that full aero pack does not work as well as the clean cut one before.

It´s all guesses now, i think they have the quickest car with or without these updates,

Looks weird as hell,

ESPN writer Chris Medland reports: it was on his return to the pits after something fell off down the pit straight. RBR mechanic recovered it late​

12:30 Now we know why the Red Bull-wing was in the morning so wrong and why Vettel was so long in the box. The world champion had made a small ride off the track, team boss Christian Horner told us. The car had to be checked only after complete, which took time.​

@ScarbsF1 Red Bull, there's something very odd about the failure mode of this front wing ​

for it to fail tail up & not nose down?​

Something fishy for sure. So what if Vettel went off, something inside the wing has just failed it seems.

[James Maskell]

If you pause at 0:13 you can see how they code the wheels

 

[Hampus Andersson]

My prediction was a bit wrong regarding how the exhausts flow, this seems to be a much better illustration on how the exhaust gases move.

 

[Kennett Ylitalo]

So it "sucks" the exhaust gases to the proper airchannel. It could be, seems logical.

 

[Hampus Andersson]

Some good info here, from F1technical.
I think instead of sucking the exhaust gases downwards it sucks the exhaust gases in that direction.

This happens at cornering speeds:​

The bridge allows the red air (exhaust) and the green air to trade places, and also guides the exhaust to where it is needed to help seal the sides of the diffuser so the RB8 can run at greater rake angles and generate more downforce.​

This happens at straightaway speeds:​

The exhaust is blown more straight aft (aided by the naca duct), reducing the sealing of the diffuser, therefore the downforce, and therefore the drag.​

He´s not an aerodynamicist but seems to have a pretty good idea of how aero works.

I´m just amazed at Newey, he just seems to operate at another level compared to other guys.

 

[Kennett Ylitalo]

How i pictured is that it doesn't spread to out, towards the rear tire but attaches it to the airflow around the cokebottle "neck" (rear of the car). I can't see that the airflow under the sidepod will create anything to spread the exhaust gases outwards. Unless the actual sidepod creates underpressure.. I'll make a sketch tomorrow, if i'm still so interested. Same stuff, just move the redlines in the top picture to be between the green lines and enginecover. Just speculation but that's how it flows in my eyes.

 

[Hampus Andersson]

According to F1T some guy says it´s been rumored that they will not run this exhaust layout in Oz.

Perhaps it´s so delicate and advanced that they need more time with it to fully understand it.
I´m sure it will find it´s way on to the car at some point during the season though.

EDIT:
Seems according to "reports" that RBR can´t get the exhaust gases to where they want them.
Bit odd hearing that from such a front runner in aero but i guess it´s just too little testing with it.

It is not about being front runner......
They probably got the theory right on the wind-tunnel but can't get it to work IRL. But this could also be a cover up so they can develop it even more. We haven't gotten into round one yet so we should take everything that teams say to serious.
