Photo comparion between the Renault R30 & R29

[bar555]

Major differences between the Renault R30 and R29
1.Nose cone
2.Front Wing
3.Front brake ducts
4.Front suspension
5.Mirrors
6.Airbox inlet
7.Airbox winglet is no longer present on R29
8.Radiators inlet
9.Sidepod panels , are similar to the ones presented by the R29 during 2009 midsession
10.Sidepods shape
11.Rear bodywork – exhaust outlets - hot air exit
12.Rear suspension
13.Rear Wing
14.Diffuser
15.Engine cover
16.Wheel rim shields are absent from all the 2010 cars

The R30 seems to be a highly developed version of the R29 , with totally new rear bodywork , totally new much larger diffuser , modified airbox zone and new nose cone . Apart from them , sidepods , mirrors , the undernose area and radiators inlets are resembling a lot to the R29 ones . Wings of course are also changed , with the rear one to adopt a new wavy philosophy with a large black colored Gurney tab and the front one to becoming tripled profiled with wavy additional second planes .Some details around the car body have also changed with the most striking of those to be the new enlarged front brake cooling ducts !

Bar555,

What do you think of the vertical ridges on the side of the R30 cockpit we discussed here?

[bar555]

R29 had this vertical ridges also . I believe that the ridge is there just to meet the minimum nose-cockpit section width dimensions by the regulations .





Renault case : chassis line in red , ridge is the red dot ( i exaggerated a bit to make the whole concept cleaner )

[Fil]

your idea is clever, 555, but doesn't quite lineup.

That the bulges on top (on either side of the R) line up with the ridges along the side tend to point to there being something internally that needs the space.

overlap of the cockpit with the FIA spec sheet.. black outlines are the FIA's drawings.

[Giblet]

Possible the bumps on top are to similarly meet minimum height requirements?

NOSE CONE


The nose cone tip is a bit taller and the nose pillars are redesigned , having now a U shape to let more air pass under the nose cone . The under nose side fences were also preserved to help manipulate air flow crossing the the under nose zone . The overall nose design is a little lower though , having a very smooth U raised section close to the cockpit and much larger front suspensions bellcrank covering bulges .



FRONT WING


The launch spec front wing version of the R30 was brought directly from the early 2009 races but during the first Winter tests the wing has changed dramatically into a triple profiled one .





MIRRORS


The mirrors mounting to the car body were altered from launch time , reverting to a semi-circular mounting element , instead of boxy , very similar to the one used on R29 .

blue arrows => the air flow
Red upper plane
Black colored under nose floor


This is a bi plane element , functioning as an air flow manager , guiding better the under nose air flow to the car bottom . Mc Laren and Williams have an under nose splitter , functioning in a similar way , which is placed much forward than that's of Renault .

that is called a 'Z0 t-tray' and it does nothing like what you guys seem to be thinking! the 'ramp' that you seem to think is a sort of diffuser has a flat floor beneath it...look at some side-on pictures of the R30. if you pay close attention to last years cars you will notice ferrari, brawn and other teams had a similar solution as well. it is simply a way to transition from the front of the splitter up to the bottom of the floor (a 50mm rise in vertical height) which also allows for ballast placement.

[Blackout]

not really similar solutions...
