BMW new front Wings?

[Crabbia]

That front wing is busy man, and i think those flaps on the front wing cause a vortices at the edges besides their best efforts to reduce them.

reason why i say this is the ferrari is the only team running front end flaps over the front end filaments and they are the ony ones that havent bothered with little winglets just above the front suspension all season. this, i feel, may be that they do not have to worry about wing tip vortices comming off these flaps as they are attached to the nose.

Ferrari run a different philosophy on their front end design. It all revolves around Shu, and what he does or doesn't want. Coming from a karting background, he wants a front end that grips well, and turns in quickly. With almost all no-keel designs having trouble with front end grip, Shu has probably told the engineers to stick with what works, and to keeep refining the single keel concept they have found successful for these many years.
The BMW rabbit ears are forward of the center of aerodynamic pressure, and thus have a destabilizing effect. But since they are fixed, they actually resist front end turn, rather than contribute.
I don't see much problem with driver visibility. The driver already is sitting low, with his sight line barely above the nose section. In front are antennae and probes. The bunny ears block very little, they just look comical.

It could be just Rory Burne choosing to stay with a concept he pioneered not necessarily MS's influence.

They even got the mid-wing like Mclaren's going on

Haven't Ferrari always ran with this Philosophy? Wait for others to perfect something before spending your money on it?

"We tested these vertical nose wings at our Jerez test. The combination of these and the new side wings on the engine cover have improved the air stream to the rear of the car and, therefore, increased downforce. As well as this they improve stability in the corners and under braking. Robert's results are very helpful in terms of the tyre decision, which will be a key factor for our race strategy."

[Crabbia]

well i hope max lets this one ride and doesn't ban it like jordans side pod wings. It's not completely disgusting aesthetically, which was what he banned them for if you read between the lines. although these 'bunny ears car be considered to bemore of a saftey issue than jordan's side pod x-wing extravaganza. those wings could pottentially come off in an accident and land up in the drivers lap.
after all it happened to jenson, but that time it was an unfortunate, and far less rigid, poor little pigeon.
It doesn't look all that aweful and lake jaslfc says it's good to see radical steps being taken by engineers. not to say they don't make radical steps every day to the engine transmission and 'hidden components'. But wings like this and aero packages in general i guess is visaul evidence of that, and shows people how unique these cars really are.

[mini696]

I agree, I like seeing these kinds of obvious upgrades.

I would hardly call it radical though.

I can't really criticise the front wings, they work (apparantly), they are within the regulations, so thumbs up to them.

The horns are a bit nicked off the McLaren for my liking, but they still look good.

[Sodder]

At least it dosnt look as bad as the Arrows at Monaco practice in 2001. The big wing on the nose. That was kinda ugly. It defiently did not fly with Bernie and the team was not allowed to run it buring the race.




Jordan also practiced with a nose wing, they too were denied use during the race. Couldn't find a pic, sorry.

When turning a corner, both vertical fins will induce wakes, but the inner fin wake will be most important due to its travel path over the rear wing.

The wingtip vortex it produces will induce a downwash component over the rear wing centre, increasing downforce, while towards the rear wing endplate [on the inside] it will induce a upwash => less downforce = less drag.

Indeed, the outer fins vortex will also induce upwash on opposite side of the rear wing.



It results in a better overall lift distribution [approaching elliptical] for reduced drag.

I think Michael's influence will be very strong - he does drive the car after all and he WILL be asking for particular things. He may not make the technical decisions, but I'm sure he sits down with designers and makes it very clear what he needs (mechanical grip/aero grip how much and when) - from that they will know how to prioritise. Seems like Ferrari veer towards good mechanical grip at the front (don't doubt the aero is good too )

The BMW - I don't suppose these horrid things have much to do with the front wing, I can imagine that they do a lot to direct air cleanly to the rear wing. Surely, the better you can get the rear wing working, the less drag you have for a given amount of downforce. There is a lot of disturbance around the open wheels, perhaps this is a way to steady to flow heading towards the rear wing. The effect of the air leaving those tabs will be felt a long way behind them, maybe creating a "barrier" from the air moving around the side of the nose and into/onto the sidepods.

Do you think the vortex would be stable all the way to the rear wing?

The horns will undoubtedly re-energise it.

edit: It doesn't have to be that strong, just a few m/s will make a difference to the effective AoA - for example a vertical velocity of 5 m/s [11 mph] will induce a 4.3 deg change in AoA at 150 mph - that is quite alot. That could be a variation in AoA of 8+ degrees from wing-centre to wingtip.

Obviously it will never work as "cleanly" in real life as a theoretical idea but you get the drift.
