Ferrari F14T , new front wing since second Bahraini test


Ferrari F14T , new front wing since second Bahraini test  1

 

     Part of the upgrade package launched in second Bahraini test, was a front wing of new breed, much more sophisticated than the previous design. All crucial wing element-parts, like the upper flaps ( increased in number and reshaped both close to nose and endplates ),under flap vanes,  cascade elements , main flap close to the endplates and even the endplate itself ( less ducted with enlarged horizontal plate on top) are reshaped in an attempt to divert air more effectively  outwards the tyre profile and generate even greater amount of  downforce.

      However Alonso faced serious stability issues ( car bumping in vertical axis)  in Melbourne, probably caused by knowledge shortage in terms of adjusting/setting up properly the new wing on car.

Ferrari F14T – Alterations on rear wing before Melbourne

 

   Ferrari tested  new rear wing endplates with unified body (yellow arrow points the old slotted version)  at last pre session test at Sakhir circuit. Additionally a mini plane briefly tested , located above the rear crash structure and between the wing pillars.

    The unified endplate retained for Australia but instead the mini plane was excluded.

D spec – second Barcelona test on March

       At second Barcelona test one more new wing spec appeared which at a first glimpse looks alike with the previous version but any similarity collapses with a closer look in details . The upper part of the wing is completely new , it has new endplates with a less intense cut on top and shortened gills which allowed the construction of a longer second flap, all changes to improve downforce production . Finally the new spec gives more freedom for mechanics to adjust the attack angle of the flaps as it sports additional adjustment points on the outer section of the endplates for that cause .

      The D spec came by with a new higher downforce front wing to keep the aerodynamic balance of the car unaffected .

At Melbourne and Sepang Ferrari discarded the beam winglet favoring greater top speed  but kept the rest wing characteristics unchanged .

Ferrari F138 – rear wing, launch version

   F138 since launch was gifted with an innovative rear wing, which sports vaned endplates. They, accompanied by multiple blade shaped elements hanging from the endplate bottom, help to extract air from inside the endplate’s zone to the outside hence improve the efficiency of both the diffuser and the wing itself . The DRS activation mechanism is also much slimmer than last year .
