Marussia Virgin MVR02 – front wing without upper decks for Glock at Italy

December 27, 2011 1 comment

   Timo Glock chose to race at Monza  a modified front wing which lacked the upper decks and provided less drag to boost top speed . On the contrary less experienced d’ Ambrosio raced the custom spec which gave him more confidence to challenge Parabolica . Glock also raced in Monza a rear wing without gurney tab for the same reason ( link ) but the top speed difference between the two Virgin racers was practically less than a half second favoring Glock . A larger gap would be expected though judging only by the different set ups , regarding downforce level ,  between Glock and d’Ambrosio cars . A possible explanation can be looked at engine usage (all drivers should use 8 engines in total for season ,otherwise a penalty is given) . Glock had No1 engine for a 4th race but d’Ambrosio No1 engine for a 3rd race .That would possibly justify a power loss due to fatigue for Glock’s engine treated with a lower downforce set up  , but that’s just no more than a speculation without solid facts .

 

 

 

 

Marussia Virgin MVR02-More front wing updates at Turkey and a higher nose since Spain


 

      Virgin struggles to surpass HRT  ,its main target for the season, thus follows an aggressive development for a small team . Another pressure on the team is to watch Team Lotus stepping fast and gradually away from the grid bottom . For sure the on going reconstruction of team’s technical staff  will need time to show clear progress on track but every new part is more than welcome now like the revised front wing first raced inTurkey  .

     The endplates of the revised wing are new, having now a bending outwards  bottom instead of having a bending inwards upper part . That is to increase a bit the quantity of air flowing inside the endplate surface close to the main plane increasing downforce . The slotted endplate philosophy remains though unchanged to bleed air through decreasing drag . Another change is the rejection of the small air stabilizer (left arrow) , a stabilizer analogous to Red Bull RB7. Finally the nose camera winglets are again relocated back inside the wing pillars , a step backwards and probably triggered by the arrival of the new higher nose at Spain.

      Speaking for the new nose ,  it stands much taller having a thinner tip and it does  provide a richer flow of air under the car and towards the diffuser aiming downforce increase  . It is good to underline that usually nose changes are followed by diffuser and floor related changes ( bargeboards , vanes etc ) .

 

Marussia Virgin MVR02 – Revised front wing in Melbourne


 VR02 had a revised front wing in Melbourne having the endplate’s outer winglet rejected (in yellow box) . That bending downwards winglet increased the ability of the endplate to divert air away from the tyre profile despite the fact that due to its negative attack angle created some lift . Probably real track  feedback differed significantly from theoretical CFD (computational fluid dynamics) data suggesting the rejection of the winglet .

Marussia Virgin MVR02 – Searching for camera winglets optimum position


In Melbourne Virgin shifted up the position of the camera winglets from inside the front wing’s pillar to nose box sides . The low placement inside the pillars trend started last season by Red Bull in Silverstone and offered a small increase in downforce production, but in Virgin case such profit was not the expected on track.
