Mc Laren MP4/24 aero-mech development in 2009

[JiMbO]

DIFFUSER - MONACO


I also noticed they added some arches to the top of the central channel between Spain and Monaco

The devil of the details in all this lies in the ports for the DD.

This pic from the official F1 site shows the RB with scoops to supply the DD, whereas McLaren have openings in the side wall. The RB scoops reach further forward too

DIFFUSER - TURKEY







FRONT BRAKES - TURKEY





REAR SUSPENSION - TURKEY


Mc Laren literally changes the lower wishbone joints to the car in every race according to the track characteristics ! Bumpy and track surface anomaly force the team to let a hole where the wishbone meats the car to prevent a possible wishbone damage while at smoother track surfaces the team fills that gap .




REAR WHEEL RIM SHIELDS - TURKEY


Mc Laren also had new rear wheel fairings fitted in both cars

what would be the purpose of those 'serifs' on the diffuser?

[bar555]

It is fluorescent paint , used to make visual the airflow and how certain parts of the diffuser are working . It was also used during winter testing .


Mc Laren brought a new diffuser which was tested but not finally chosen to be raced . It seems that many teams bring new parts a race earlier to apply and test them during free Friday testing because of the test ban rule .

interresting how many diffuser updates mclaren is making, this is their 8th or so already, seems that here is the problem.

I meant the pointy bits at the top corners of the diffuser. Are they vortex generators? and how do they help the flow there?

[wesley123]

they probably do the same as those vertical fins in there

Im really enjoying this forum and threads like this, i have been reading it for ages but now ive decided to join in.. on topic i notice hamiltons car is using a new rear diffuser with a much wider cut out for the top plane, in addition to a revised front wing at the nurburgring this weekend whilst kovalainen makes do with the current parts as a comparison.

[BreezyRacer]

Lots of changes to Hamilton's car .. according to the pics I've seen ..
massively revised rear diffuser
engine cover (without those bulges now!)
floor (now more like RB with flip ups at sides)
nose looks different .. maybe wider not sure though
new front wing
revised sidepods, turning vanes, and barge boards at splitter areas

In short it looks like they've done a lot of repackaging on the mechanicals to conform with other successful designs as much as possible. Looks like it's working for them .. or at least for Hamilton. Hieki will just have to wait.
