Interesting Photos from Monaco Practice

[Carbon]

Hi Everyone, I've stumbled upon some very nice technical photos from Monaco's practice sessions, care of a Japanese website:

Notice Ferrari's chimney which was described in an earlier post, and the airbox winglets on the Renault.

Does anyone have an idea about the sensor on the Williams, vibration sensor perhaps?

wow i did not know, you can take pictures that close. Any way you have any thoughts on this grand prix, looks like a very interesting one to me. Was it jaguar that got third place a couple of years ago here? any way they are workin on this new aerodynamics design, lets see how it will work out

To me it seems a static pressure sensor....a very strange one.....but with does holes on the top and side.....it's a wild guess!

be it whatever it is,putting this cube on top of the wing and sticking a cable to the flaps with tape you could not assume the device itself would have some influence to the cars behaviour as everyone makes us believe this area is soo sensitive and influences the whole aero package.
Williams still fighting their generic setup in the first practise sessions with lots of frontend bouncingaround over the curbs and porpoising on the straights surely limiting their brake performance.
Ferrari in contrast going over the curbs almost without any disturbance of the car ..the tyres must be really great in soaking up those bumps as I could barely see any pushrod movement at the front in the slomos.

Definitely a sensor.Probably used to analyse how the front wing reacts to such high downforce....not sure.
Any body realised that teams like Ferrari and McLaren are cutting extra holes on their sidepod.Monaco isn't as hot as Malaysia...so why are they doing it???Is it because the heat cannot be dispersed from the circuit beacuse of its buildings???

Maybe because there never is a real straight and a low avr speed in general, it might all cause less air getting to the radiators. Above that it's a lot of accelerating from low speeds so it might all have extra heat as a result.

@Macrush: I believe it was somewhere at these forums where I read Ferrari brings only 3 types of damper settings to a circuit.. maybe they are really adavanced on that earia compared to the 'bouncing wheels teams' like williams..

Yes, it’s an accelerometer.

[Micky]

Why would they put it there. They usually have one on top of the nose. Could be a load sensor or to measure amount of flex in the wing.

[Reca]

They put it there probably to measure the vibratory response of the wing structure.

A few examples of accelerometers :

Well it seems that the tusks supporting the front wing are flexing....so they put the acelerometer there to see if it's true...and if so in which conditions. Probably they used it at monaco because it«s the circuit that has the highest front end downforce....

They can test the flexebility by placing wights on the wing.
If the wing would flexing than the wing would produce more downforce than calculated by the team.

Yes, of course, they can, but the best way to measure the flexibility (and any other parameter) is en working conditions (mounted and being in use in the car). By adding weights, they will have later to make heavy calculus to extrapolate the results to working conditions, so....why make it so difficult?.....just put a sentor whatever you want and measure it!
