FRONT WING - BAHRAIN
Image


FRONT WING - AUSTRALIA
Image

The revised front wing’s endplates had a new higher and curvy outer winglet [1] extending up to the cascade , which have now a smaller triangular endplate [2] instead of the previous rectangular one . Moreover under the cascade there is an additional small outer vertical fin [3] which increases air pressure . Finally the under wing certical fence [4] was repositioned closer to the centre of the wing . All the changes aim to redirect airflow managing around the frond tyres reducing drag .

At China an inner horizontal floor extension was made in order to channel air more efficiently under the wing and close to the endplates .

F DUCT , REAR WING - BELGIUM
Image

Renault initially declared that would not intend to waste time and effort on developing its own version of the F-duct system but rather on extensive R30 development . Several months have passed since then and now at Belgium Renault presented its own version of the rear wing stalling system . The team obviously changed mind and voted yes for developing its own version , even though the F-duct system would be out of rules next season , probably because firstly the R30 shows great potential and secondly the battle with Mercedes GP for the 4th constructor’s championship position is within realistic reach .

Renault’s decision to have its own version paid off at Spa as Kubica was high on top speed list . Furthermore the team evaluated the system to worth up to half a second in the long Spa track but according to Kubica Renault is not going to re-use the system at next race at ultra low downforce track of Monza .

Image

As all versions of the F-duct system so Renault’s one is operated by the driver’s left hand . Inside the cockpit and behind the driver’s left shoulder there is small rectangular hole connecting the system to the driver’s operating control area . If we take a closer look on the cockpit area behind the driver we can a see that the introduction of the system caused the left rear cockpit wall to rise up a little so as to fit the system’s tube .

Image

The system itself receives air from two little holes placed on either side of the airbox ( 1 ) . When the system is activated by the driver at straights the air entering the holes mentioned before , feeds the main plane of the rear wing ( 2 ) , which is connected to the system via a small inclined downwards tube hosed inside the engine cover . When the system is inactive the air then flows out and under the wing’s profile ( 3 ) via another tube (black colored) placed further below the first one . Nevertheless the exiting flow from the black lower tube is directed above the extra winglet mounted on the wing’s beam so as not to block the airflow onto it .
A clever evolvement of the system would be to sent the exiting air , by first speeding it up using a Venturi effect inside the tube , directly onto the winglet to maximize the downforce production

SIDEPODS - ENGINE COVER MODIFICATIONS AT SPA
Image

Alongside with the introduction of the F-duct system the R30 featured also elongated to the rear sidepods and a new engine cover .

Image

Image

The thermal protective cover and the vertical inner fence were moved to the rear and are now spotted under the rear’s suspension wishbones , a changed triggered by the elongation of the sidepods and the floor exhaust outlets to the rear .


Image

The new engine cover presented at Spa has a new upper part which can be separated from the rest cover body to offer more freedom to mechanics to enter inside the cover and reach the engine and F-duct system internals . Moreover the cover is elongated significantly to the rear and features a small cut ( blue arrow ) where it meets the upper suspension’s wishbone .
