Ferrari first introduced these at Imola, to help extract the heat generated by the rear brakes. The lip of the shield separates the hot airflow from the rim walls, helping to stabilise tyre pressure by limiting the effect of the brake heat. In Turkey the concept is pushed further, with a wider lip section reducing the size of the central air vent. This improves air extraction still further by decreasing turbulence generated by airflow close to the wheel. It also slightly improves aerodynamic efficiency in this area.

Ferrari certain wheel fairings are legal

By Jonathan Noble Saturday, August 26th 2006, 09:18 GMT

Ferrari's wheel fairings at the rear, during Friday practice in IstanbulFerrari have no concerns about the legality of the innovative rear wheel fairings seen again on their car this weekend for the Turkish Grand Prix.

The 248 F1 was fitted with the brake cooling devices at Turkey, having originally appeared in the season-opener at Bahrain.

As autosport.com reported earlier this year, a rule clarification issued over the winter allows teams to fit bodywork on the inside area of the wheels.

And despite Renault's mass damper system being outlawed mid-season, Ferrari technical director Ross Brawn has said he is adamant there will be no repeat scenario with Ferrari's design.

"That area of the car was very well defined in the regulation change that happened over the winter," explained Brawn.

"We've discussed it with the FIA. If someone comes along with a different opinion, then like with the mass damper the FIA could take a different view.

"To the best we can, we've kept the FIA informed of everything we are doing and asked if they are comfortable with the solutions we've found.

"That's only an opinion and, if a team chooses to object, there is a process to go through. At least today, the FIA are happy with the system, and unless there is a different perspective that someone has about the devices, it should be OK."

Brawn also insisted that there should be no suggestion that the devices fell under the 'movable aerodynamic device' banner, because they provided no more benefit in that area than normal brake ducts.

"I think that all brake ducts I would say have an aero benefit," he said. "You have to provide cooling at the minimum cost. They are all involved and part of the aero package.

"I don't think anyone is designing a brake duct that's not taking into account aerodynamics."

Technical updates

Wheel fairings

Ferrari have raced with carbon fibre fairings fitted to the outer rim of the rear wheels since the opening race in Bahrain. While the other teams' protests and media attention were focused on flexible wings, the equally questionable adoption of these fairing was ignored.

In fact, the fairings were allowed under a clarification to the brake duct rules agreed by the FIA and the teams' technical working group (TWG). Now Toyota have also adopted fairing over the rear wheels, in a solution that is bound to be adopted for the upcoming high speed and heavy braking circuits, such as Canada and Monza.

The rules allow an area on the inside face of the wheels for bodywork. This has been used for the scoops, which are used for brake cooling, but the rules also allow bodywork to sit within the wheel, and hence we've seen the barrel-shaped ducts sitting around the upright and brakes since 2001.

Ducts exceeding the dimensions allowed under the rules are subject to penalties, and several teams have been penalised for just such infringement over the years. Most recently, McLaren and Renault have sported small fin-like brake ducts below the larger ducts on their front wheels. Although these "ducts" did provide some cooling, their design was largely as a flow conditioner for the front wings wake.

Then, last year Ferrari and Toyota went a step further and produced bodywork on the inside face of the wheel in the allowable area for brake ducts, but the devices were not inlets and hence could not be used for any form of brake cooling.

The FIA demanded that these "ducts" must constitute some form of cooling duct and not simply be a closed aerodynamic profile. Both teams opened up a conciliatory inlet, but the primary function of the devices remained as an aerodynamic aid and not for cooling.

Over the winter, the TWG agreed that any bodywork within the area defined in the rules was freed up, and as such did not have to function as a cooling device.

Ferrari arrived in Bahrain with a novel take on the revised rule, using bodywork on the outside face of the wheel, but critically still within the boundaries set out by the FIA.

Initially, these were simple flat hoops, but these were subsequently updated in Imola, where the fairing now became three-dimensional and formed a tube going inside the wheel.

The flat fairing probably acted more as a streamlining solution for the wheel than for any form of cooling, but the revised "duct" would certainly have some effect on brake cooling. It works with the barrel and donut-shaped ducts inside the wheel, to route the heated air more effectively away from the brake and out into the dirty air, passing around the outside of the wheel.

Aanschouw de hedendaagse F1. Voorkomen door überchance, en een snellere achter je kunnen houden omdat de circuits zich slecht lenen tot inhalen tenzij het snelheidsverschil seconden per ronde bedraagt.

Ik walg. Alweer. Vuile hoeresjansaard.

och man daar kunde echt wel inhalen als het geen sec scheelt
maar idd alonso weel alle geluk da em kan hebben



hoeda als em een ronde langer bleef rijden was em meer plaatsen kwijt

zowat het hele veld heeft duidelijk bewezen dat inhalen goed te doen is op dat circuit

Ferrari had massa maar moeten buitenhouden en schumacher eerst binnen laten komen + dat schumacher 5-6 sec verloren heeft door van de baan te gaan. ze hebben het zelf gedaan
