GP Week : Issue 49
Technical Update: Round Here in Turkey all the teams introduced many changes on the cars. Among them, Ferrari brought an F60 deeply modified in many details aiming to improve the balance of the car on this technical track. Williams on the other hand concentrated its efforts on a new front wing following the same principle of the BrawnGP’s version, while the championship leading team adopted a completely new movable flap for its front wing. 1 – F60 revised front wing As part of a complete package of changes on the F 60, Ferrari have modified their Brawn-style front wing endplates, introduced in Spain. The second vertical element, placed on the edge of an arch shaped knife-edge profile to manage in a better way the airflow around the front wheels, has been increased in its height, compared to the version seen in Spain (inset). In this way the turbulence generated by the front wheels is further reduced, so improving the efficiency of the front wing at slow speed. This, understandably is particularly useful here. 2 – F60 wheel fairings Ferrari, as mentioned, introduced an array of small changes, with the most significant ones represented by modified front wheels fairings, and the revised front wing endplates. The first change features a lip extending forward, partially covering the sidewall of the tyre, and then connecting with the central section of the fairing, sporting a big round slit with a ‘thorus’ shape. The function of this element is to provide both a better diversion of the turbulence generated by the air coming from the front wing and impacting the rotating front tyres – but even more it helps in terms of dissipating and diverting the hot air flow generated under braking outside and towards the rear. This of course helps in general terms of brake cooling, but also aerodynamically, in terms of improving the quality of the 14 airflow passing underneath the car, close to the front section of the sidepods. 3 – Ferrari F60 new diffuser Ferrari also introduced a further evolution of its double decker diffuser. Apart from reflecting the same details as the previous version seen in Spain and Monaco, that features two wide holes in the side walls of the central channel; the main difference is related to its weight. Ferrari introduced a lighter version of this element, to improve t e weight distribution of the car, as much as possible, while making a small gain in over-all weight. 4 –F60 rear wing The rear wing of Ferrari has been deeply revised not just in its main profile, but also the endplates now sport a sort of upper triangular cut (slit) in their rearmost edge, so as to reduce the turbulence generated by the airflow exiting the main profile. 5 – Williams FW31 front wing The Grove-based team introduced a completely new front wing, that features an assembly deeply inspired by the one of the Brawn BGP 001 The endplates are not a single element any more; instead the foremost part is also the outermost one, diverting the airflow outwards, so to reduce turbulence. As well, they sport an additional double profile on top so to increase the downforce generated at the front. The wing main profile, on the other hand, features a slightly sinuous profile, raising at the extremities, close to the endplates 6 – BrawnGP front wing development The front wing of the BGP 001 underwent a revision of the movable flap that in the previous races sported a flat squared upper edge. It now features an inclined exit profile, bending downwards in its central section. This change provides an improved sharpness of the front end of the car, particularly important in this track that features multiple radius corners. 2
