FIA: Ride height devices would be illegal
By Simon Strang Wednesday, April 7th 2010, 15:24 GMT
The FIA has told Formula 1's teams that any self-levelling damper system used to regulate the ride height of a car between qualifying and the race during a grand prix weekend would be deemed illegal.
An FIA spokesman confirmed to AUTOSPORT that the sport's governing body made its position on the matter clear by faxing the teams last Sunday night with a clarification on the use of suspension in Formula 1.
"Any system device or procedure, the purpose and/or effect of which is to change the set-up of the suspension, while the car is under parc ferme conditions will be deemed to contravene art 34.5* of the sporting regulations," read the communication.
The move follows Red Bull Racing's stringent denial during the Malaysian Grand Prix weekend that it was using a clever system that lowered its cars in order to maxmise their potential during qualifying - with team boss Christian Horner insisting that not only did Red Bull not have such a device, but that it would protest any team that ran one.
The FIA gave the RB6 the all-clear after a thorough inspection during the weekend, but rival teams have suggested that Red Bull may have found a way to achieve the affect without the use of a mechanical system.
But another line in the communication suggests that any such solution may also be outlawed: "Furthermore we believe that any self levelling damper system is likely to contravene 3.15** of the technical regulations."
McLaren indicated last weekend that it intends to develop a system of its own that would allow it to exploit its car's low-fuel potential, while Mercedes' Ross Brawn has called for a clarification of the rules.
*Article 34.5 states: If a competitor modifies any part on the car or makes changes to the set up of the suspension whilst the car is being held under parc fermé conditions the relevant driver must start the race from the pit lane and follow the procedures laid out in Article 38.2.
** Article 3.15 states: Aerodynamic influence :
With the exception of the cover described in Article 6.5.2 (when used in the pit lane), the driver adjustable bodywork described in Article 3.18 and the ducts described in Article 11.4, any specific part of the car influencing its aerodynamic performance:
- must comply with the rules relating to bodywork
- must be rigidly secured to the entirely sprung part of the car (rigidly secured means not having any degree of freedom) ;
- must remain immobile in relation to the sprung part of the car.
Any device or construction that is designed to bridge the gap between the sprung part of the car and the ground is prohibited under all circumstances.
No part having an aerodynamic influence and no part of the bodywork, with the exception of the skid block in 3.13 above, may under any circumstances be located below the reference plane.

Renault add revolutionary double floor
On Renault R30 At GP Malaysia
Now that the diffusers have become so much more important, the whole floor of the car has a much increased importance towards the efficiency of the whole car. Renault haven't missed out on that aspect and have added a double floor to its R30.
The team introduced a huge aerodynamic step at Sepang, including new sidepod panels, barge boards, a modified diffuser and a double splitter. Apart from its normal function of splitting air from in between the front wheels to the left and right sidepod, the new device also marks the beginning of a double floor. Right above the reference plane is now an open area of about 3cm high. Looking closely at the image you can also see that this floor space is extending under the side impact crash structures and under the whole width of the sidepod. While it is not perfectly clear yet how this air channel is used, the diffuser update that came with it suggests that this is used to feed on of the upper channels of the rear diffuser.
Just as with the underbody airflow, the stream in this channel will be accelerated due to the expansion that happens in the diffuser. As such, air is sucked from the front of the channel, reducing drag at the front while increasing downforce at the rear end of the car.

En ce moment, la voiture évolue a grands pas, on peut dire qu'elle a terminé la phase 'rattrapage du retard' et qu'elle est entrée dans la phase 'innovation' au niveau des évolutions aero. Elle est même en passe de devenir une des monoplaces les plus sophistiquées du plateau (Valence est très loin), mais je je ne sais pas si les perfs suivent vraiment et s'ils sont conformes aux attentes... Peut-être que la monoplace attend ce 'truc' qui fera fonctionner toutes les nouveautés ensemble et révèlera leur vrai niveau, un peu comme l'aileron avant de la R28 apparu a Singapour et qui a transfiguré la monoplace en quelque sorte.
On verra si cette monoplace a encore une grande marge de progression ou si elle va atteindre ses limites très vite et faire du sur-place. Les deux éventualités sont très possibles.

c'est ce que j'ai trouvé, mais mon anglais par contre m'empêche de capter le coté technique
