Red Bull RB9 Renault

I think that tape of solid prebend metal support on RB splitter is just very simple. No wires, no suspensions thingy and other to obvious and impossible systems. Joe Bauer, Charlie (FIA technical marshals) just doesn't falls from tree and teams either. I think those ideas really assault its cleverness. Sorry guys i respect your opinions just what is to much is just to much. NO hush and bad feelings. Just remember make thing ingenious is just art how make things looks very simple.

I bet this is just "abnormal" memory alloy witch react differed around static and frequent instant dynamic load.

I will just look or everyone else who had already experience with that type of alloys could post further infos. Cheers!

AMuS The Secret of the Y250 vortex

[oT v1]

I'm not really sure what is implied with 'riffle' but here are the tech regs, in case I've got this one right, being non-native English speaker:

It means grooves cut (in a slow spiral shape) into the exhaust. and of course the origin of the name comes from cutting the same spiral groove in a gun barrel to spin the bullet, making it more accurate.

Are then through the tunnel does not pass air, and to use it to create a vacuum which draws the flow of air to the car and thereby prevents the flow to break apart? Sorry for the translation but use üttülğ translator.

They had this engine cover vent in Austin (last time seen in YTD)

[aral]

As I said friday, they had new engine cover vent

That vent has been used many times this year and last year

Yes, you're right! "New" isn't the right word

I think the initial bend is an optical illusion caused by the camera lense, I would say the stay was perfectly straight and only bends when the car drops.

The pre-buckle is already there (images from different GP's showing it)...

yes i think its pre-buckle

It can be working as a tension leaf spring. Te pre-buckle just sets the clearence to ground on a static situation taking in consideration that the critical moment will occur under braking. While on acceleration and with speed increasing, aero forces will lower it, as the rear bottom and therefore maintaning a more or less constant clearance.

Joe Bauer, Charlie (FIA technical marshals) just doesn't falls from tree and teams either.

But Charlie rarely if ever proactively investigates these kinds of things. He runs the tests the FIA requires and if the car passes, then generally he's O.K. He usually only steps in if there is a formal complaint or a request for clarification, and even then his responses are limited to the scope of the question presented.

Interesting picture - first time vortices get some coverage. But iirc what we saw is not the y250 vortex, it is the flap vortex. The y 250 is the one that runs low close to the ground towards the t-tray.

The Y250 vortex is created at the tip of the wing, designed to drive airflow along the axis 250mm from the centerline.

All the flows along this axis either drive under the floor to the diffuser or via the undercut of the sidepod.

Anyone caught Webber´s stop with the camera pointed backwards?

Buckled as he´s coming in, they lift him up then drop him and the stay buckled quite severely.
It definitely looks like it´s connected to the suspension load rather then just the floor hitting the ground but i could be wrong.

I posted something similar back in 2010 on Scarbs' blog:

"I’ve been thinking about how Red Bull could have incorporated a flexing splitter with the RB6.

The connecting stay between the splitter and chassis is also connected to the front suspension internally. As the front suspension is deflected upwards under aero load of the chassis deflecting downwards, it pulls the stay and front tray up via some sort of internal mechanism, thereby acting a little like an active ride system.
Considering how Red bull have developed a front wing that has been designed to flex, it may not be so far fetched that they’ve done the same with the splitter and some internal mounts.
So perhaps the connecting stay and part of the front suspension is connected to an internal support that flexes."

The idea was that the internal carbon fibre mount connecting the suspension and stay would be flexible under load. I don't believe this is the case however.

Excepting for suspension and brakes and other systems. No mechanical motion parts are allowed on the body or chassis of the car. So it cannot be connected to the suspension.

[PlatinumZealot]

although some people on other forum speculated that they have riffled exhaust pipes in order to induce a vortex trajectory which is further amplified by fences or vanes arrangements on the floor at the back of the car.

I thought you weren't allowed to rifle the exhaust pipes?

I'm not really sure what is implied with 'riffle' but here are the tech regs, in case I've got this one right, being non-native English speaker:

5.8.3 The last 100mm of any tailpipe must in its entirety :
a) Form a thin-walled unobstructed right circular cylinder whose internal diameter is no
greater than 75mm with its axis at +/-10° to the car centre line when viewed from
above the car and between +10° and +30° (tail-up) to the reference plane when viewed
from the side of the car. The entire circumference of the exit should lie on a single plane
normal to the tailpipe axis and be located at the rearmost extremity of the last 100mm
of the tailpipe.
b) Be located between 250mm and 600mm above the reference plane.
c) Be located between 200mm and 500mm from the car centre line.
d) Be positioned in order that the entire circumference of the exit of the tailpipe lies
between two vertical planes normal to the car centre line and which lie 500mm and
1200mm forward of the rear wheel centre line.
5.8.4 Once the exhaust tailpipes, the bodywork required by Article 3.8.4 and any apertures
permitted by Article 3.8.5 have been fully defined there must be no bodywork lying within a
right circular truncated cone which :
a) Shares a common axis with that of the last 100mm of the tailpipe.
b) Has a forward diameter equal to that of each exhaust exit.
c) Starts at the exit of the tailpipe and extends rearwards as far as the rear wheel centre
line.
d) Has a half-cone angle of 3° such that the cone has its larger diameter at the rear wheel
centre line.
Furthermore, there must be a view from above, the side, or any intermediate angle
perpendicular to the car centre line, from which the truncated cone is not obscured by any
bodywork lying more than 50mm forward of the rear wheel centre line.

THe size rifling you need to get any meaningful vortex from hot turbulent open bore exhaust flow would have to be preeetty huge... I don't see it.. and then again, your exhaust has to be a CIRUCULAR cylinder. A rifled cylinder is not thin walled or circular.

It doesn't need to be, just needs to 'happen' to connect to the same piece of chassis that reacts the torsion bar/damper loads...
