But if they want to use it in a race then it should perhaps be testet if theres changes to the internal crash structure of the nose with this new design.

And i dont believe the plough will come back with this nose. I believe the same of some others here who said that this will add some balance rearwards so that they can start adding a bit to the FW again.


No the rules for this year is that you must have everything crash tested before you test stuff. You didnt follow pre testing? Marussia failed crash test and missed their one test.

IF this is the hot setup, why did they not spend more time with it during the test? They are only marginally better using/understanding the current tire vs. the competition.

Maybe because it is east to asses. Not much to see buy down-force and drag numbers on that track :-k Balance issues for one driver might not be for another I guess.

McLaren can adjust the brake ducts?
In addition to the nose could still see something interesting in Mugello. Both Paffett and Turvey came during their long runs every now and again briefly in the box, parked parallel to the garage and drove to a few seconds further back. During the brief stops were not as commonly changed tires or temperatures measured. They could see only two mechanics here who feigned on both sides of the airbox with a little crank spins. The only question is what?

Without a glance at the Carbon Dress we have no definitive answer - but a hot suspect: Even before the Mugello test there were already some rumors that McLaren is said to have developed a new revolutionary ventilation of the brakes, during a race can be adjusted. Initially there was speculation that the system will only work on the rear axle. The competition but now believed that it is both front and back tested.

Temperature regulation for tires
The benefit is easily explained: The system is not about the temperature of the brakes but the heat output can be controlled from inside the rim of the tire. The first Grand Prix of the year have shown there: Who can race Sunday to respond to temperature fluctuations, has a big advantage. The new Pirelli rubber of the 2012 vintage will only work in a small window.

It would be a real coup if the engineers had found a way out of Woking, adjust the temperature in the tires during the race. Since it is the brake ducts to aerodynamic parts, the driver from the cockpit itself is nothing to adjust active. If there is no other trick would have to make the mechanics during a pit stop, the necessary settings.

At the pit stop to get but not ran directly to the brakes without taking the tire change in the length. There must be another solution be found. Have the necessary screws will therefore be moving into the central part of the car? Perhaps we are in Barcelona a little smarter. Auto Motor und Sport is tuned but definitely on topic.

Did they come to the box during their long runs in Barcelona (test), didn't they?

Is this true?

3.15 states that for any part of the car influencing its aerodynamic performance must be secured to a sprung part of the car. Does this mean then by definition that brake ducks do not provide aerodynamic performance?

So what would prevent the use of a driver 'on track' adjustable duct system?

2) Goal of changing the temperature of the wheel/tire:

A) Change the gas pressure in the tire
B) Change the temperature of the tire itself... effect the tread compound, etc.

I think the issue with a driver adjustable one is asking, is a brake duct an aerodynamic device, if it is, then its not allowed, if it isn't an aerodynamic device, your fine.

there is more problems though, if it is deemed not an aerodynamic device, then people will start taking the mickey with the brake duct fins and making them active aswell, which means it has gone from being adjustable duct to a whole adjustable rim/ brake assembly, so I think it should stay as being controlled by the mechanics in the pitstops :)

I believe this device is an answer to the tape issue that Mclaren had with lewis' pitstop, well thats my opinion.

respect to gary anderson, also it's definitely a improvement, it's still a low nose but i think they have take this approach to help the rear tyres maybe by improving the aerodynamics underneath the car helping the diffuser, or it could be simply for tracks like barcelona
but all teams should do that and make the bump dissapear and have a smooth curve

Funny that Gary Anderson gets the last laugh that you mention it. The old bumbling Geezer's (I still can't understand him when he talks!) is actually pretty sharp after all. :P

Gazzetta reports McLaren did pass a new crash test for the new nose and says McLaren will test it Friday in Montmelo. And that the new nose will allow more aggressive aerodynamic solutions.

Even McLaren goes to the stepped nose? (almost)
At Mugello the Woking team has
surprised everyone with a nose much higher off the ground,
but especially with the wavy pattern in the
upper part (circle to the right). It was an
experiment, but also on Friday at the
practice of the Spanish Grand Prix at Montmelo we will see this
solution that resulted in a new crash tests. The
Corrugated high nose allows greater passage
air in the lower part and then more aggressive aerodynamic solutions.
Finally McLaren would
follow the Mercedes GP in an attempt to
introduce the f duct on the front. In the circle to
left the nose used in the first 4 races.

You mean the grill in front of the rear tyre? It's just a grid-like device used to measure the path of the exhaust flow, and maybe the velocity of the flow from that region of the bodywork.

No i mean the thin silver tube on the left side (right for us)of the rear wing!
Not the devise that is sitting near the exhaust flow!

Loom for the sensor array.
