Looks like some flexural loading of the rigid body rules going on there...

That's what I was thinking as well with that slot.

So, to get back on Topic:

The McLaren Updates in Malaysia by AMuS.

This also shows the lower mount for the turning vane has been moved forward and closer to the sidepod.

Vortex Generators push the front wheel wake over the rear wing, as a ambulant air flow creates less down force at the rear. good idea to have 3.

You want the front wheel wake as far away from everything as possible. In fact you want to reduce the front wheel wake as much as possible. That is where the idea for having so much out wash on the front wings came from. The blown wheel nuts. And generating a vortex around the front wheel though the use of the out was front wing and the turning vanes under the nose push air into the low pressure, twisting mass of air. By reducing this twisting and tumbling of air you reduce the negative effect it has on aerodynamic parts further down the car. By reducing the size of the low pressure region and reducing the low pressure gradient behind the tyre you are reducing the drag created by that wheel. Therefore controlling flow around the front wheels is critical to both reducing drag and creating downforce at the back of the car.

Speaking of blown wheel nuts... do you notice that only the brave teams are trying to learn it? Mclaren, Red Bull, Ferrari... The benefits of it must be worth all the trouble. I think Ferrari have got a good handle it now though.

This article confuses me.

I thought that the McLaren Honda would be more competitive in the cooler temperatures. And judging by the Buttons comments they were running more downforce compared to other midfielders, that is why they could enjoy better cornering speeds. Well lets see what they will bring to China, but it does not look promising.

Yes I noticed that. I think part of the decision if to use it actually comes in terms of pit stops. As we saw with Williams it does increase the chance that teams will mess up the pit stops somewhat getting the wheelnut drill onto the nut. Maybe some of the lower budget teams can't afford to take this chance.

Structurally I think this part may not be so simple to design and manufacture, further pushing teams with a lower budget to not pursue it.

On terms of it aerodynamically I am sure some people have thought that pushing more air through the rim itself will do the same thing and probably they are right. However to do that you have to push more air through the brakes themselves. This changes the very sensitive characteristics when it comes to transferring heat from the brakes to the wheel rim. Keeping the tyre temperature within range is far more important than the little bit of aero benefit by having more air flowing through the rim. Here is where the blown wheel nut comes in (BWN?). It allows teams to control how much airflow they want going through their brakes to control tyre temperature while at the same time it allows them to push more air through wheel nut to help control tyre wake.

Interesting comment from Button,saying China cool temperatures will hurt Mclaren aero advantage over others.

I glade someone has posted this, thanks. I read this earlier and I just do not understand at all, why would cooler temps hurt aero in general, and why would it hurt McLaren more?

Cooler temperatures allow other teams to close up their rear bodywork more allowing for greater diffuser performance and rear end downforce. It can actually make quite a large difference. McLaren aren't in a place to close up their bodywork because a. It is already very right and b. They are still having temp problems, closing up the bodywork will just make exacerbate their problems.

The difference is likely to do with the fact that cooler air is more dense.

Found it on Autosport forums, it's from the Malaysian race.

I bet Button was referring to low temps hurting McLaren wrt tyre usage

All ratings

Does anyone know how those ratings work?

[RicME85]

Its just a ranking of each driver between 1 and 10 for those categories isnt it?
