Ferrari 150° Italia

[Richard]

Ringo is talking about the geometry relative to a plane along the centre line of the car. That fin is at a camber to the direction of travel.

could be an amplifier for a strain gauge

According to my bro, it is a tyre temp sensor. It measures it through the hole.

This car is useless. Surely, it would be fast on track with anormaly high temperature like at Valencia.

I dont believe that. It cant see the tyre from that position.

I don't think the wing's on the car, Holm...

EDIT : I totally misunderstood your post, Ray Sorry for this spam!

[Holm86]

Doesnt make any diffirence ... It would still be blocked by the winglets at the rear of the wing. It cant see the tyre from that position. And by "It" i mean the sensor not me....

There's a small cutout behind it where you can see daylight.

yes but this blends downwards so seeing the tire from that point is impossible

[raymondu999]

Maybe they're measuring to the extent which rivals are using hot blowing then, by their exhaust temps?

[Lurk]

You can see the undercut from below in this picture.
Maybe it is only an optical illusion but I'm pretty sure that the bottom is curved and not flat and the hole is near the lowest point. So you should be able to see what is behind.

It would be easer if we had a picture of this sensor from behind to see if there was an IR cell or not.

[marcush.]

where is the logic for an IR sensor? the view angle is bad from that position and tbh there are better areas to put the sensor to view the front tyre temp and distribution.

funny that Sauber had something similar on the front wing at least a lot of tape going towards and on the endplate (hiding cables and equipment).

I would say tyre temp is a usual feature so you would not need to improvise the installation.

My guess is it is something out of the ordinary and you would even sacrifice aero performance to get this information.

An accelerometer seems just too heavy and of course this would spoil your result just by having that mass in that area ...

So whats left ? something to measure distance -IR or sonar or what have you -
a small camera to observe a feature under real world conditions
or a amplifier box for a strain gauge

airspeed measurement -but : doesn´t the presence of the bit disturb the airflow not too much to give a good read?

Sure the teams evaluate their test setups first under controlled conditions (windtunnel,straight line )to get a baseline before using up valuable free practise time ,so you get at least an idea of the offset you are creating by having the equipment in place.

I´m still rather surprised that teams not have more sampling equipment on their cars on fridays.I sure would collect as much data from as many sensors and device as possible to create a data base for work at home .

It´s September now ..almost a year on from pirelli tyre introduction and suddenly Teams find out how to use them -RedBull,Mclaren ,Force India ,Toro Rosso....took too long ..

the only logical sensor that could be is an accelerometer, to measure the behavior of the wing due to vibrations induced through the suspension.

Possibly to enhance their CFD model with transient vibration modes to see how this effects the air flow around the car.

[Lorenzo_Bandini]

Q. (Fabrizio Corniati – 422Race.com) Mr Domenicali, correct me if I'm wrong but it seems that in this race you are again using the old suspension which you were using again in Spa and not the new one which you used at Silverstone for example and which seemed to reduce the problems of getting tyres up to temperature, which had been a problem for you throughout the season. Could you explain the reasons for this choice?

SD: It's true, we are also not using that new… well, that different suspension but the reason is different. For sure our engineers believed that with these track conditions, that kind of suspension is not helping to improve the car otherwise we would be stupid not to use it, so that's the reason why we chose the other solution.

I found this very strange.

You would not put that big block in that area to measure vibration ....it affects the outcome of your measurements too much.There are really tiny accelerometers for this sort of testing available or you measure on optical/laser basis.
