1)

McLaren can adjust the brake ducts...Since it is the brake ducts to aerodynamic parts, the driver from the cockpit itself is nothing to adjust active.

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.

maybe they need it for their ddrs

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

[PlatinumZealot]

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.

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.

What is that silver thing on mclaren rear wing?

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.

Nothing special.

What about this and this

It seams to me that they are trying something...

The device on the tip of the nose cone maybe a laser measuring device to measure any pitch and changes in ride height when the car is in motion.

Oh just wait until Ringo see's this new McLaren nose. He's been on about the low nose from day one.

I don't think it's a big deal. Why not switch to something that works better if the team determines it is in fact better. The low nose can't be attributed directly to any poor performances.

The benefit of the new nose comes not only from the added height, but primarily from the more elliptical tip

There was some chat on twitter that said it was likely a track specific modification. I guess we'll find out in due course.

Entirely plausable that they'd bring it for high rear downforce dependant tracks, and drop it for tracks needing a pointy front end.
