An interesting solution of the front wheels Williams

The tests in Barcelona, which was first presented to the new Williams FW35, the specialists ' attention was attracted by the unusual design of the front wheels. It turned out that the engineers managed to find an interesting solution in the area of the airflow around the front wheels.
The whole system is similar to the host Red Bull Racing, presents Grand Prix of Canada last year. The air entering the cooling system brakes through special channels in the wheel hub, with the outer side of the disk. This solution significantly reduces the aerodynamic resistance in this problem for designers area.
However, Red Bull had to abandon this design, because the FIA deemed it inappropriate regulations. Weekend openings, rotating together with the wheel, was interpreted as forbidden by the rules "moveable aerodynamic elements.
Constructors Williams has considered this problem by proposing another implementation. On the FW35 the air is not through the disk, and fixed through a special channel in the hub of the wheel, and then, naturally, goes into the holes of the wheel. Thus, all the elements that are used for flow direction, motionless, but the effect is almost the same as on the machine Red Bull in Canada.

However, the Williams engineers had to completely redo the mounting structure of the wheel, in order to meet the standards of the FIA (the wheel should stay on the axis even if the mounting nut is not tight). However, they managed to cope with this task.
They reviewed the entire design of the site. The locking pins were mounted directly in the nut, and unlocked when the impact wrench. Of course, this resulted in the need to create a special wrench.
