Red Bull RB7 – Monza’s rear wing details

January 25, 2012 1 comment

  GP of  Italy

     A special low downforce rear wing was presented in Monza which had an even lower attack angle than that used in Spa and also lacking the endplate slits . Surprisingly Vettel , who was helped by Red Bull’s special aero package, managed to take pole against all odds favoring Mc laren  and even to dominate in race in most convincing way .

Red Bull RB7 – new rear wing at Canada



    In Canada most of teams are accustomed to introduce new rear wings im order to achieve greater top speed at long stretches , so did Red Bull . The new wing had a reduced chord and attack angle of the main flap , the V cut in the middle section of the second flap was also gone and there were new horizontal slits instead of curved on the endplates . The same wing spec was raced at Belgium




Red Bull RB7 – Rear end revisions for Spain


       In Spain Red Bull had a new upgrade package featuring several rear end modifications . In particular the diffuser inherited a winglet under the rear  deformable structure which blocks the hot air coming from the two outlets sitting on either gearbox bottom sides to enter the central diffuser section from above . So the only remaining access of those hot emissions to the diffuser is through the engine starter hole .


      Another change is that the rear wing’s endplates gained vented extensions similar to the ones seen on Mc laren and Sauber quite a long time now .Worth’s remembering that Toyota was first to exploit those extensions back in 2009 to help diffuser extract air from under the floor more efficiently, because they divert air flow outwards.

     Additionally the lower combo of the rear brake winglets were also new , being now angled upwards.

Red Bull RB7 – rear wing, launch spec details

      RB7 raced the same rear wing spec from launch to Monaco despite the fact that rival top teams moved to updates of their wing . Of course some flap angle adjustments took place but are irrelevant to structure changes  . This sounds bizarre especially for a team which won the championship last season and won it again this season too .

         Lack of development may well reveal lack of sources but not for Red Bull case .It can be well explained by looking closely on the clever design the wing features that needed not any refinements .

     The DRS mechanism is very  efficient due to three major factors , first the short chord of the movable second flap , secondly the way the mechanism is housed and  functions and lastly the horizontal axis which permits the flap to move upwards and downwards letting the team at the same time to perform adjustments on the wing itself (see circular inlets). To increase the amount of downforce produced by the smaller flap , there is tab across the trailing edge while the V-cut in the middle cut drag .

     The strongest argument of all is the fact that  Ferrari and Mc Laren at midseason reverted their DRS to look alike Red Bull’s .

PS = At Spain there were changes at endplates bottoms. Furthermore angle attack adjustments are not considered to be revisions, for example the lower attack angle at Turkey and the higher at Spain and Monaco the flaps featured respectively.
