Red Bull RB8 Renault

[beelsebob]

Hello at all

I' m new to this forum and i have a question please , where can i get somthing lik this?? (technical draw) for the Red Bull RB8

i will be very thankful for help

This drawing is almost certainly simply traced from a side view image of Lotus's car. Simply grab a vector graphics app and trace the RB8, and you're there.

i try all the time to draw it but the result is unconvincing

It would SEEM completely legitimate to have a duct that cools the wheel bearings. This would not be a brake duct. Cooling the wheel bearings would be a valid 'primary' use for such flow. To say aero is the 'primary' use seems like a stretch. Do we have anything to demonstrate how it would be an aero benefit.

We are missing some detail in this story.

This post was back June 9, when the Red Bull wheel bearing holes were discussed. The comment "We are missing some detail in this story." has stuck in my mind for all this time, and I have a theory on another intended use.

We are all aware that all the different tire compounds have different optimum temperatures, and getting tires up to their proper operating temperatures has been a major issue all season. The McLaren solution was to have a system where during pit stops a mechanic could adjust an opening inside the brake ducts to suit the required operating temperatures of the different compounds. But it was complex, it required action during a pit stop and added extra complexity and mass to the car.

But for the Red Bull for that period of time, they attempted to use the size of the wheel spoke openings to regulate temperatures? The center has holes to cool the bearings, but further outward, if you had different sized openings in the spokes, you could tailor (restrict) the airflow to optimize brake temperatures to suit the different tire compounds?

If this was true, it was an elegant and simple solution. No need for a mechanic to adjust anything during a pit stop, no hydraulic lines, you just matched the tire compound to a wheel with specific-sized holes.

Wont that depend on using different wheel specs. Because that isn't allowed.

I was wondering about that to, but did not find anything restricting difference in opening sizes in Article 12, which deals with wheels and tires.

I had considered that a possibility but did not think the openings near the center were up to the task. Maybe that is an incorrect assumption.

I can see where one could might consider the manner in which the mounting surface of the wheel is machined as not being controlled by the rules.

From the latest edition of Autosport magazine:

There was another crucial regulation clarification behind the scenes on the eve of the season that further foiled the plans of Adrian Newey and his design team. The dimensional cone, aft of the exhaust, prescribing where no bodywork was permitted, extended as far as the rear-wheel centre line. Red Bull interpreted this as allowing ducts behind that point that would capture the exhaust flow and re-direct it to the exact point around the diffuser it was needed. The RB8 was conceived around this feature – which simulation had shown would have been highly effective in clawing back a big chunk of the 2011-style exhaust’s aero benefit. The FIA outlawed it a month before the car was due to appear.

Mid-way through the season I did actually wonder whether this sort of system could be introduced. In my head I envisaged attaching some sort of duct similar to that the Nissan NSX Super GT 'snorkel intake' to the edges of the brake ducts to route exhaust gases directly to the floor. Clearly I wasn't the only one!

Great minds think alike obviously

[raymondu999]

It was already clarified by mid-season though

If anyone is interested i have some close up pics of the RB8 from the Autosport show, and a shot of inside the tunnel on sidepods, if you would like me to share then just let me know. Im not gonna upload them now because i know there from an earlier spec car and maybe useless.

[wesley123]

Why wouldnt you upload them?

dont troll, if you have something to show, show. if you dont, dont post anything. You wont get nothing for collecting unnecessary post, it's not that is some reward in it.

Go ahead. Old spec or no, folks are most likely going to at least recognize which spec it was and then trace it back to the race(s) it was used in and try to get a better understanding behind the pace of the RB8 at those GPs. This would be particularly nice for the early part of the season when new RB8 specs were being rolled out nearly every other race weekend (and sometimes fresh from race to race).

Upload them however you wish. If they're hi-res and many, I would suggest just linking to the album itself rather than posting each photo, individually.
