what the stupidly high ariel fin on the Ferrari F1 car?

Hope that just for testing.

 

Glad to see those nasty wheel covers have gone :)

 

It's a pitot static tube, and yes it's there just for testing. ;)

 

What was wrong with the wheel covers? They were a technical advancement....

I have to say best looking car so far goes to virgin Racing. I hope its faster then they expect, coz it looks like it should be and I like Timo Glock.

 

Those wheels covers were horrible even if they did smooth the air past the wheels

 

though looking at the front wing on the virgin it doesnt appear to have all the gubbens and additional wings on it like the other teams...hmmm

and looks to have a short wheels base in the picture

McLaren insist there is no need for "alarm bells" after the team's MP4-25 was spotted with a rather unusual device attached at Jerez on Wednesday morning.

 

Concerns were raised about McLaren's 2010 challenger at the first pre-season test at Valencia last week when the MP4-25 was splashed with 'fluminescent' paint.

 

Apparently it's used for measuring aerodynamic flow structures.

 

 

Any comments Tony? :)

that device will be seeing what the wing and wheels have done to the air and how disturbed it is or whether its smoothed back out.

 

It could be that Mclaren are just collecting as much data as possible because testing is so limited they can then put these peices of data and get their simulator programs to try and match the changes or alter their design programs to work more accurately to real life behaviour.?!?

That's exactly what it is.

Yup just some pitot static arrays, nothing trick.

They had similar devices festooned around the defuser of last years car during the tests. It's stuff that all teams do in one way or another, usually during one of the dedicated straightline aero tests that we're allowed each year. They're also quite fond of flow vis-ing the car which is when you spray the bodywork with a parafin based luminescent dye. You then send the car out and as the parafin evaporates and the dye effectively dries in a 'streaked' condition you can see how the air is flowing around the bodywork or whether any flow has become un-attached.

 

You're kind of right with the device invalidating it's own data, but that's where the skill of pitot static design comes into play. Things like making sure the static port is 12 x the diameter if the port downstream from the total port (IIRC!!).

No doubt they would have run it in CFD as well to ensure that the array as a whole doesn't effect the results too much as well.
