Anyone any ideas what McLaren would be testing with this rear-wing apparatus - aero loads? Stresses? Flexing?:




And heres a nice photo of Ferrari's new innovative conical wheel nuts designed to help shave tenths of a pit-stops/tyre changes now there is no refuelling so tyre change speed gains extra importance - also as a side note - automated jacks are now banned as it was feared this could lead to a spending race by teams to develop the most innovative and fast jack equipment which is a shame for Williams for as far as I can recall in the recent past, they have always used motorised jacks in their stops! :

McLaren's device helps them get Freeview in the car.

As for Ferrari's wheelnuts, we all remember what happenned last time they tried to shave time off pitstops. I wonder if this will see a repeat of the traffic light fiasco?

Just a whole load of pressure taps on the McLaren. I've done the same thing at *******F1 (don't bother counting the *'s - just a random number!) on the front wing/flap a few years ago. Interesting data and a pain in the butt for the poor guy who has to plumb the whole thing up.

I guess the Ferrari idea is that the wheel gun doesn't need to be lined up as it is put on, which would save a couple of tenths I guess.

There's a good explanation of Ferrari's nuts here:

They can automatically trigger the wheel gun and a light to signal when the operation is complete.

Clever. Anyone like to place a bet as to who'll make the first wheel-related cock up of the new season? If they're trying to change tyres in under three seconds I can imagine we might see at least one car leave without all four properly attached. I mean, they had 16 years of refuelling and still messed that up from time to time..

Air flow over the top of the rear wing? Or maybe its linked with the new 'Pit Lights' they are testing?

thats a good wager. i see your view lol!!

THEY ARE PRESSURE TAPS. Measuring air speed from the underside of the wing.

Ah right fair enough.
I assumed as the teeth of the sensor was over the top and rear side of the wing, that was where was being measured. Very confusing stuff..

Underwing flow is just as important as overwing.

The device is measuring both, most likely, as one reading without the other is pretty much useless.

That makes sense.

[Vapepreab]

Of course it's confusing to you, it made the air go swish.

Fyi, Underwing flow is just as important as overwing.

Quite, if the underwing flow is not faster than the flow above, there is no negative pressure on the underside and hence - no downforce.

Perhaps they are looking to see if there are any points at which the wing 'stalls'.

Interesting to me is the fact they are measuring the left side. Is this to see if there is an effect from the small air intake on the left side of the nose not too far ahead of the cockpit?

Incidentally, air does not go swish. It's its intraction with an obstruction and the friction (drag) thus caused which produces the sound.

Thank god you're here to explain it to us mere mortals.

Ouch! About as subtle as a Ferrari press release.

Flow over the top surface of a wing is almost irrelevant. All the work is being done by the low pressure side. I've seen tunnel tests when something like a small tool or pen is left on the top surface by accident and it didn't show in the results didn't even move much. On the other hand I've seen flow separation on the underside caused by decals. You wouldn't believe me if I told you how fast the air exits off a high downforce wing t/e.

I'm sure very soon Tamb will inform you that he is an ex aerodynamicist for Benetton and doesn't need you telling him anything..

They needs their gadgets.

It could very well be so that they are not among the four front runners at the start.

Any straw .....

Eh? Did you not see the jerez lap times? That car is proper bo.

I'm surprised nobody has brought up the new Ferrari shark-fin solution yet:
