Ferrari F2012

What would the team be adjusting with this setup? Are they just verifying that the splitter would pass the test if required?

Yeah that' what it looks like.

Indeed it is. Having half or 1/3rd the turns cuts time and the thicker threads would tend to be less susceptible to cross threading...Macca could learn something in this.

This seems like a well developed area for any type of racing that requires single nut wheel changes. We are talking about a number of decades and something the is very easy to model. I find it odd that baring the introduction of new materials, that there is much new in this area of the car.

I would put it down to a different mix of benefits verses risks.

That was a good observation by Scarbs. Are the wheels homoligated at the start of the season? This looks like something the other teams would be able to easily jump on.

Well done Crucial--as always.

Elegant, and also a little funny; so simple a solution that nobody noticed yet. I associate to the thanks list for Crucial.

as I understand you are obliged to have a nut securing the wheel .But who said it needs to be a thread? having less thread is putting more load on what is still there.
I think the wheel securing should be done differently ,the wheeel nut just providing a means of input but the clamping provided by a means of hydraulics .
also it is clear to see that a nut is not a failsafe means of attachment. time to do something better.

Today in Bahrain
...

What's going on at the trailing edge of the DRS flap? I see the very obvious gurney, but what about all the other steps?

[hardingfv32]

Just as a side note: The Gurney on the flap adds around 20% extra downforce to the second element.

Do you have any source for that?

[hardingfv32]

Do you have any source for that?

I remember that I was impressed by the number. I believe it is in this report:

GOFAST-1 Final Report

AER E 462: Design of Aerospace Systems

Professor: Dr. Steve Holland
Advisor: Dr. Dale Chimenti

Client: Mr. Matthew Orris, Lockheed Martin Corporation

I think is new:

[alogoc]

yes it is!

That was fascinating thankyou. One calculation showed a 20% increase in DF with 8% increase in drag which was pretty beneficial.

Note how the downforce numbers of the second element are almost equal to the drag number. Nothing efficient about the RW second elements at high AoA.

I love those little details http://www.formula1.com/wi/0x0/sutton/2 ... brn410.jpg - the pneumatic air.
@hardingfv32 - that's to measure the splitter deflection.

James Allen reporting that their speed is also down to new jacks:

Here's a sensational stat from BBC Radio 5 live commentator James Allen. Ferrari are seven tenths of a second quicker than the next fastest team - which is McLaren - when it comes to doing pitstops. That's an incredible advantage. Allen puts it down to a couple of fancy new jacks. "The team have some work on the front and rear jacks," he said. "They are a work of art in themselves. The detailing that goes in the hydraulic rams is incredible."

And a bit more about the mid wing:

BBC F1 Technical Analyst Gary Anderson
"If you look at Fernando Alonso's car, he's got a mid wing mounted above the crash box. You're allowed 150mm of width there. What they're trying to do is get the flow of the upper wing to talk to flow of mid wing which talks to flow of the diffuser. It makes the diffuser work more efficently. They have one of those on Alonso's car but not on Massa's car so that's why they've got the flo-viz paint on both cars - to compare results."

[amouzouris]

new cascade wings?? they are much smaller where they meet the endplates:
Edit: they are not new..they've been like that since China


nice view of the starter motor hole and the space occupied by the acer ducts:
