In 2003 for 16races they had something like 18different race spec car.tomazy wrote:if my count is korect, this is allready williamss 5th difirent rear wing this year1-australia, malaysia, bahrain, spain, 2-monaco gp, 3-canadian gp, 4-us gp, 5- 2nd and 3th day at silverstone testing
it realy does look like thay are developing track-specific wings all year long
I agree the Ferrari are venting to the inside of the wheel on the rear by using the rim shields, but why is the front rim shield a more rounded profile than the rear one (which is perfectly flat)? And why does it stay in place instead of rotate with the wheel?Well, for the rear wheel rims it improved aero as it channels the hot expelled air flow from the brakes to the rear wing increasing its efficiency.
Obviously there are no wings to channel the air around immediately behind the front wheels, so what benefit can you get out of using them? Because we've already proven they don't help braking performance. Is there some other aerodynamic benefit from them?
Ben, great pics by the way
what if it was another way of "Bending" the rules? If that thing doesnt rotates with the wheel, then it is not moving! whether it was an airo device or not, right?ginsu wrote:I agree the Ferrari are venting to the inside of the wheel on the rear by using the rim shields, but why is the front rim shield a more rounded profile than the rear one (which is perfectly flat)?

Well, I'm guessing it's for purely aerodynamic reasons. The ideal aerodynamic device on a rotating wheel would probably not rotate (causes a lot of drag), and you would want to make it a bit rounded as it would fill in some of the low pressure area on the side of the wheel. So, the optimal aerodynamic shape has been found, but it must really screw up brake cooling, so I would not expect to see these solutions on every race track unless they can do something about the cooling airflow. Possibly, they will vent to the inside of the wheel at some point, if not already. After all, they already have wings mounted to the inside of the hub.
The suspension arms also move, dont they?modbaraban wrote:How about moving/rotating sideways while steering?allan wrote:what if it was another way of "Bending" the rules? If that thing doesnt rotates with the wheel, then it is not moving! whether it was an airo device or not, right?
the same applies for those small wings inside the wheels, which ferrari started using way back in the 2005 season...
Exactly, if its a "part of the rim" it needs to be homogeneous, but if its "part of the brake cooling system" it can be made of almost anything.Tp wrote:Allan, the grey area with the wheel rims, is that being part of the wheel it needs to be integrated as part of the wheel out of an homogeneous metallic material, which clearly it isn't, but Ferrari justified it to be part of the braking system instaed, allowing Ferrari to continue to use it.
