For the Tech Junkies

Thanks Joe.

 

WOW that Mclaren wing is clever.

 

Yeah, well it says around 3-4kph difference so if thats accurate then it's only around 2-2.5mph more in a straight line. Doesn't sound much but it might be a lot different actually being tested like in Monza for example.

 

Thats very interesting stuff, and very well written. I've been looking for something like this. Thanks for sharing it!

 

The problem for McLaren though, is that because it is such a simple piece of engineering, all the other teams will have a version of it in no time and then there goes their advantage. The hardest part is working out the correct air pressure required to stall the rear wing and I can't see that stumping the engineers for too long.

Also, unlike last years double diffusers, this concept is alot easier to incorporate into the car without a major overhaul of the aero balance.

In my opinion it's some smart thinking from McLaren but they've shot their bolt too early!. By the time we get to Spa and Monza, they wont be the only ones with it.

 

Hold the bus!! it may not be a easy as you think: This year the monocoque is also is subject to homologation and hence cannot be altered until the 2011 season.

 

Love lurking the F1Technical forums... The race-by race aero development threads are very interesting.

 

Whilst the homolagtion rules may prevent a direct copy of the McLaren design, trust Me, if the other teams decide the advantages are worth it, they will design their own version one way or another.

 

LOL trust you nah, I trust no-one..

The point is, it is not as easy as you think, it is not the copying that is the issue it is the fact that if they do change the tub it will be subject to FIA testing again, if that is allowed I don't really know.

I agree the other teams will have a work round I'm sure, like you say IF they think it is worth it personally I don't think it is.

 

that site's going on my favorites. Thanks.

 

Wow, all those little articles are interesting!

 

I doubt it is worth the effort. The size of that duct has a big impact on the overall shape of the bodywork (-> engine cover area) and requires a lot of aerodynamic tuning The question is if all the effort involved to redesign the cars would not lead to a bigger advantage if spent on other parts of the car.

 

Didn't Ferrari have some sort of hole in their front nose in 2008? Any ideas what that did?

Edit: There we go, parallel to the front wheels in the middle.

Thanks for the link, its awesome.

 

This hole was to relieve the high pressure underneath the nose and thus reduce the drag created from the difference in pressure.

The front splitter that Williams ran last year directly under the nose serves a similar purpose, to relieve the pressure. McLaren is running a similar idea this year.

This type of hole that Ferrari ran in 2008 though is banned under the new rules.

 

Thank you very mcuh for the excellent link!

A great sourcs of informatoin. Thanks for giving away my secrets

 

This was mentioned on a Ferrari forum a month or so back . . It's a bit older , but the info should be accurate . Scarbs usually is...

 

I have been a long time fan of F1technical, if you read through some of the threads you will see past discussions involving wing stalling ( currently being used by Mclearen ) and breather holes feeding the defuser. A brilliant site and always worth a look
