Red Bull RB8 Renault

[gerishnikov]

Brian if you really think that any team, let alone the defending champions are using a 2011 chassis then you have clearly gone full retard, and you never go full retard.

2011 chassis design of coarse, not reused parts.

Look at the RB8, except for the hole in the front bulkhead, why do you need a new chassis? The chassis is from the nose mounting area (front bulkhead) to the front of the engine, correct?

Brian

The reason for the stepped nose was due to teams wanting to reduce costs and use tubs from last year. If not, then why was the compromise agreed?
If a new tub was to be used, the teams could just as easily used a lower bulkhead, as per McLaren

not the case!
the compromise was reached so the majoroty of teams didnt have to change their total design philosophy of their cars. absoloutly nothing to do with cost cutting.

In the case of RB, what features have you seen that require a new chassis design other than the 'letter box' opening? Chassis = Tub (nose mounting front bulkhead to engine mounting rear bulkhead)

The car is quite good. I don't know how good the drivers are.
Webber had many fastest laps at malaysia. This car is not slow by any means.

To be knocking on the podium with only mclaren faster than you is definitely not a failure.

The car simply doesn't have the qualy pace it used to. It also seems last year's car spoiled the drivers. Vettel is saying it's not easy to drive for some reason.

China will show that the car is still good, though i think they need a better exhuast solution or a reversion.

The top speed is also interesting, as last year the car was quite good in a straight line if they race warranted such a setup. Monza was evidence of how well rounded the rb7 was.
I wonder if Newey has figured out the problem?

Well I guess that's a fair-ish assessment, considering Alonso and especially Perez were in a different league today

Agreed.

I'm not sure China's a very good benchmark though. I think Sepang (other than the searing heat) is a good test of aero in itself.

To the A-spec?

It never was. The car was always designed for the fastest average speed over a lap. In Monza it was the slowest in the speedtraps.

Did anyone notice adrian newey watching ferrari's new front wing before the race start he was looking closely as if he was interested in that design as if it was worth a look.I wish i had a screen cap of that.

[Lycoming]

well, that design does appear to have borrowed heavily from the RB7's front wing so that may have something to do with it too...

[MIKEY_!]

Maybe looking at why they have so many elements on that wing.

Well Ferrari had a pretty much identical front wing to the RB7 so any updates that Ferrari did to it will obviously be of great interest to RBR. Saves them a job.

yp...its probably the 5 element part that is very interesting..

Red Bull Exhaust comparison, Malaysia vs Australia



Red Bull reverted to the exhaust bodywork arrangement used during the final days of Barcelona testing rather than the revised one used in Australia(inset). This was after a back to back test Friday. The exhaust outlet of the one used appears to point further outboard, but without the same extent of surrounding walled bodywork to guide it.

Gary Anderson:

Red Bull is trying to get the airflow to come down to the lower corner of the bodywork and get involved with setting up a vortex to seal the floor. But simulating it with mass flow of exhaust, as well as mass flow of the whole car, is very difficult. You need to play with temperature sensors on the bodywork to see where the hot part of the flow is going before channelling it where you want. The Coke Bottle will not be as effective because of the blockage of the exhaust. Part of what the Coke Bottle does is drag airflow inward that would otherwise go under the floor, so with the exhaust in the way you need to help prevent that flow from going under the floor. The hole you see here creates a bigger low pressure area, allowing the flow to be pulled towards it rather than below the floor. To get the pulsing exhaust flow working(it's not just a constant flow) during simulation is very difficult. Circuit testing is really the only way to do it. This layout may be as a result of what Red Bull found from the heat sensors.

So are Red Bull paying the price of not putting this exhaust solution on their car from launch?

McLaren went with the outboard solution from day one and collected a LOT of data and tried a few positional adjustments before bringing their big refinement to the final test.

Red Bull tested a completely different solution, that by some accounts was illegal due to the amount of heat shielding, before trying to launch a completely different system in the final test. Be it arrogance, reacting to the other teams (they perhaps planned an alternate centrally mounted system that got the exhaust to the floor), or just the amount of time they took to design their solution; they simply just don't have enough miles on the car to fine tune exactly where the exhaust is going.

All that said this probably isn't their only problem. Their car overall doesn't seem to have any more down force than the McLaren's yet is much slower in a straight line. So sorting the exhaust may move them a bit closer but I think McLaren will still have the edge. And all the while they're spending time and money on fixing the exhausts McLaren will be bringing further refinements to their entire car.

I wonder just how much effect the exhausts are having? Is the McLaren solution vastly superior to the rest or is it simply a better overall car. Is it possible that no matter where the exhaust gases are channeled they really aren' that effective and the differences in performance are more prosaic?

The RB exhausts just seems to go against everything they have done so well with the rear of their car for several years. It'll be interesting to see if they persist with the bridge or opt for the more elegant McLaren style bulge.

Makes you wonder with the pace of the lotus how much of an effect the exhaust has now.

This is the correct summarization of the current state of F1 aero development. The team engineers accomplished their goal when developing these new exhaust rules.

It would appear that the EBD is a massive loss for only RB. The back end of the cars dont hold the road aswell as last year, thats obvious. So its clear RedBulls EBD was the best.

Getting the Front end to turn in is one thing, Its getting the rear to follow which is the hard part.
