Ferrari F150o – Rear wing specs for Spanish race


  tested version

       A clever interpretation of the rules was seen on Ferrari’s new rear wing at Spain . In details the wing featured an oversized slotted tab fence across the trailing edge of the second flap that made the wing exceed over the maximum allowed height by about 3 cm ( the maximum height is set to be no more than 95 cm from the bottom of the car ) . Ferrari claimed the tab to be part of the flaps separators ( flaps separators are rigid impervious supports , Ferrari’s wing had three supporters , one in the middle and  two more neighboring the endplates  ) . FIA   disagreed with Ferrari interpretation of rules and found the wing to break the article 3.10.3 of technical regulations forcing Ferrari to wrap the disputed wing and race a revised Turkish version.

Article 3.10.3

In order to ensure that the individual profiles and the relationship between these two sections can only change whilst the car is in motion in accordance with Article 3.18, they must be bridged by means of pairs of rigid impervious supports arranged such that no part of the trailing edge of the forward section may be more than 200mm laterally from a pair of supports. These pairs of supports must :

– be located no more than 355mm from the car centre line ;

– fully enclose each complete sections such that their inner profiles match that of each section. With the exception of minimal local changes where the two sections are adjacent to each other, their outer profiles must be offset from the inner profiles by between 8mm and 30mm and may not incorporate any radius smaller than 10mm (‘gurney’ type trim tabs may however be fitted between the supports) ;

– be aligned as a pair so as to provide a bearing across their full thickness and along a profile length of at least 10mm when the distance between the two sections is at its closest position ;

– not be recessed into the wing profiles (where a recess is defined as a reduction in section at a rate greater than 45° with respect to a lateral axis) ;

– be arranged so that any curvature occurs only in a horizontal plane ;

– be between 2mm and 5mm thick ;

– be rigidly fixed to their respective sections ;

– be constructed from a material with modulus greater than 50GPa.

These supports will be ignored when assessing whether the car is in compliance with Articles 3.6, 3.9.2, 3.10.1, 3.10.2, 3.10.4 and 3.10.6.

 

  race version

            The version used in Spanish race  had new endplates with slotted  extensions to the bottom similar to the ones featured by Mc Laren , Red Bull and Sauber . Their use is to improve diffuser efficiency  . Another change is spotted on the beam wing having now  a new non slotted main section .
