Ferrari F2012 – rear wing evolution from Monaco to Silverstone (including Mugello Test)


G spec – Debut : Mugello test on May , raced : Not yet
Notices : It is actually the wing raced in Spain (F spec) without the mini plane .Ferrari tested at least three new types of rear wing ( F ,G and H spec) at Mugello before the Spanish race .

H spec – Debut : Mugello test on May , raced : Not yet
Notices : It is actually the Spanish wing ( F spec) with a small vane on top of the endplate ( in yellow circle ) aiming drag cut . The endplate vanes featured since the Australian spec ( C spec ) force the air flowing at the outside surface of the endplate to follow a similar pattern with the air flowing inside them . When the two air-flows meet and mix at the trailing edge of the endplate will eventually create weaker vortexes favoring top speed .

I spec – Debut : Monaco , raced : Monaco
Notices : New wing for Monaco.It is actually a hybrid between the Australian ( C spec) and Spanish (F spec) wing . The second flap recovered the V-less profile while the gills reshaped curvy once more . The mini plane is also new having now a double profile, a wavy main flap and supports having the front edges to curl outwards, all to create more downforce ( the old mini plane  in inset) .

      Beyond Monaco Ferrari brought back the Spanish spec .Of course some adjustments on wing attack angle were made from race to race to suit better with each track special characteristics .


New rear wing at almost every race from Scuderia Ferrari

         Teams revise the car’s front and rear wings during season to make them function better. Any front wing revision is though  regarded more crucial because an optimization of air flow towards the central part of the car is offered additionally  . However over  the last seasons  all teams choose to develop more and more sophisticated rear wings. There are three key areas that teams usually work hard to improve . The upper part of endplates aiming drag reduction, secondly the flaps themselves to generate more downforce with the minimum possible drag and thirdly the lower part of the endplates to  improve the way diffuser functions . Very important also is the efficiency of the DRS , a factor added in the already complicated equation that aero designers have to solve since 2011 .

       Speaking for Scuderia Ferrari , solid steps made on rear wing development rate with the fruits of hard labor to deliver from Australia to Spain  at least  6   specs ( named below with capitals letters from A to F)  .  None wing, apart from the last F spec, was radically different from its ancestor but rather a modification so as to cope better with the rest numerous developments that have taken place on the car  (front wing, vanes, bargeboards, exhausts, diffuser). The different specs listed and analyzed below

A spec – Debut : Launch and early testing , raced : no
Notices : There are three air vents on endplate top surface , a V cut in the middle of the trailing edge of the second flap to cut and three flap fasteners

B spec – Debut : Barcelona test on March , raced : no
Notices : The V cut in the middle of the second flap vanished , there also new endplate bottoms to improve diffuser efficiency

C spec – Debut : Australia , raced : Australia and Malaysia
Notices : spoilers added on endplate outer surface

D spec – Debut : China , raced : China
Notices : there are new air vents which are four in number  and also more curved ,a new main plane , double V cuts on the trailing edge of the second flap and two flap fasteners instead of three

E spec – Debut : Bahrain , raced : Bahrain
Notices : mini plane addition to add downforce

F spec – Debut : Mugello test on May , raced : Spain
Notices : A rear wing of new breed with a new main profile and an upper flap to merge with the endplates featuring a different gilled pattern. The new air vents on the endplate are more in number and straight instead of curved like they did before .The vanes at endplate bottoms are now doubled in number from two to four while the beam wing is  raised in the middle section and wavy .The small cut at the point where the beam wing meats the endplate helps to decrease drag and even the rear light was reshaped to help the middle raised section to generate even more downforce .
