Korean GP 2010 - Yeongam

[Shrieker]

Higher speeds = greater load = more flexing = wing ends closer to the ground = less disrupted air flow = high speed.

That's my thinking and I'm sticking to it (unless I am wrong of course!)

Higher speed = greater load = more flexing = more downfoce = more drag = less straight line speed

Just to annoy you


Talking about predictions... It's crunch time for McLaren.Hamilton will be fiercer than ever, going all out for a win. The championship contenders would do well to avoid him, and that might give him a little bit more chance

[spinmastermic]

for Sh@#$3 and giggles...

1. Schumi
2. Sutil
3. trulli...

I love it

[RAF]

THe first three to DNF?

my wish list.

1. Hamilton
2. kubica
3. Button
DNF Vettel
DNF Alonso
DNF Webber

Now that's a result I would like to see... Although I'm not sure, I'm struggling with my support for Webbo. I like the guy, I'd like to see him WDC (and a new WDC), but I don't like his driving and I don't care much for red bull. Part of me wants him to win it. Part of me wants them to take each other out at the next race.

Alonso I can deal with just about, but I can't stand Vettel.

No annoyance at all. I don't pretend to know a whole lot about aerodynamics and appreciate all input. Cheers.

the bending has been used to reduce drag as well ...but I don´t hink the front wing bending is used in this ways as well by RedBull?

I think in this case the Red Bull is using the lower front wing to scavange more air before the front wheel and control more of the air. Leave it to the experts in this area, however I think it has more to do with increasing downforce, not necessarily on the front wing, and explains why we don't see as much flexing on the higher speed circuits.
RBR to get the front row in qualifying, only to be swamped on the straight by the McLarens.
RBR chance for victory will be determined by the advantage of the undercut of the new tyre at the tyre change, and whether they can stay out for longer and put in the faster laps.

[djos]

Im hoping for the following:

1: Webber
2: Jensen
3: Hamilton
4: Nando
5: Vettel

Btw, Redbull have a new more advanced F-Duct for Korea to improve straight line speed.

surprising

on the F1 2010 game which they say they got all data for the track, the pitlane exit is on the exit of T2...

I can run 1:35's in the game..... whatever that is worth!

I don't have the F1 game to try to make driving comparisons. Perhaps, Sean you could provide some driving feel comparisons to Malaysia, China, & Turkey. I think this Korean track layout & length (5.6km-18 turns) is most comparable to these 3 tracks.

2010 Quali pole times for these races (except for Malaysia) are:

Malaysia 5.54km – 15 turns = 1:37.0 (fastest lap in 2010 race) and (1:35.2 in 2009 Q3)

China - 5.45km – 16 turns = 1:34.6

Turkey 5.34km – 14 turns = 1:26.3

Japan 5.81km – 18 turns = 1:30.8

Something doesn't jive with the Malaysia-Japan & China-Japan comparison. Malaysia & China are shorter in length & in no. of turns, yet Japan Q3 is faster. During this yr., have the cars performance increased that much? I realize the average speed of the tracks may differ slightly, but still...is the avg. speed around Japan that much faster to create a Q3 time difference of approx. 4 sec. faster to China? Korean track is 200m shorter with same no. of turns as Japan. Thus, at that rate, I would have to guesstimate pole in Korea will be sub 1:30.

the battle i am looking forward is with the redbull and the Mclaren... so basically all the cars will be running a low downforce setup...

and Ferrari?

[marcush.]

I think RedBull has by design of his car a rake angle steeper than all their opponents as their tubbottom is not flat essentially -is exploiting the the +/-5mm tolerance to create a rake in their attitude in this (effectively having a kink in the bottom surface just in front of the drivers bottom...This ways they will not be able to run the car as low at the rear as others at maximum speed ...which is in effect contributing to not decreasing their downforce on the straighjts as much as others can do ..and this adds up to a drag penalty .. causing them to be a tad slower than others.
If they chose to lift the carfront on the straights to kill the downforce ..this si contradicting with their flexy front wing design..so they live with it and complain about a weak engine ..

[Shrieker]

@marcush,

Interesting explanation. Sounds plausible though.

[wesley123]

I have to disagree with that. As marcush said they cannot run the rear as low which is wrong, as then they would lose alot of downforce(and thus reducing their strength), so imo that is not true.

What my idea is is that as they have the movable splitter and fornt wing is that it flexes under speed, allowing way lower front ride heights, also explaining why even the center is that much lower to the ground compared to other cars.

[PlatinumZealot]

If you run the rear higher you get more down force. At least you run it high enough so that the boundary layer does not interfere with your main flow and not so much that you have turbulence. A rake also gives your car body a more wedge shape so you get some DF from that too.

After some deliberation on the flexi wings and soft front suspension I think the RedBull has no tricks, its just better. I mean some websites selectively show the pictures of the wings touching the ground but there are also images of the mercedez and renault wings touching the ground as well.

[wesley123]

and what about the diffuser then? I am pretty sure that just loses downforce

[godlameroso]

maybe at ride height difference of over 10mm would let you notice loss of downforce, as it is a slight amount of extra rear ride height does more to change the balance of the car than the downforce. Although you will run more downforce by running the rear lower, you have to compromise, if the rear was lower than the front the driver would not be a happy camper.
