Mc Laren MP4/24 aero-mech development in 2009

NOSE CAMERA WINGLETS - CHINA


The new front wing for Hamilton forced the team to relocate the nose camera winglets higher and backwards on the nose cone .Probably the airflow behind the additional upper flap extension would be effected negatively by the former position of the winglets .





ASYMMETRIC EXHAUSTS - CHINA
RACE


The team used asymmetric exhausts for the race but for free practice sessions a symmetric configuration was tested .




FREE PRACTICE



There a small vertical fence to decrease the overall size of the right exhaust’s outlet and minimize the turbulence created by the hot air exit

STEERING WHEEL - CHINA




ENGINE COVER


Golden foils under the car’s skin ,around the engine’s area , offer a better heat protection



AIRBOX CAMERA WINGLETS - CHINA




DIFFUSER - CHINA


1.higher vertical fences
2.winglet beneath the crash structure and above the dipped centre of the diffuser

GP BAHRAIN








Undergone changes from China
1.Kovalainen had his nose camera winglets repositioned also
2.Rear suspension’s lower wishbone joint to the car had been changed for one more time



FRONT WING - BAHRAIN


Hamilton preferred to use for a second race the new style wing , already used in China , while Kovalainen chose again the old version

The lower wishbone’s joints to the car undergone several changes since Launch time . Moreover the lower wishbone in China was thicker close to its joint with the car .

Is it my eyesight and tricks of of perspective, or does the degree of curavture vary in those body work pics? Some seem tighter than others. The China pic seems flatter and much less sculptured

The China pic also seems to show a boot on the lower wishbones.

I have another good picture from Spain that i am planning to post which clearly show that Mc Laren had changed again the rear suspension's lower wishbone joints !! So it is not your eyesight or tricks of perspective

[connollyg]

How many sets of paddles are there on the back of that steering wheel?
And anybody know what they are all for? i think i can see 5, Obviously clutch and gears account for 2, what are the other 3 for?

[scarbs]

Mac use six paddles, two for the clutch and two for the gearshift, the differing pairs of gearshift paddles are to access different engine maps. So that one pair are on a softer map to improve traction and the other pair are on a more aggressive map for maximum acceleration when traction is not an issue.

Many teams use this multiple set up (Ferrari, Renault, Brawn, Force India)…

GP SPAIN



Undergone changes from Bahrain
1.A double profiled front wing with new endplates was tested but not used for race . Kovalainen decided to use the double profiled front wing like Hamilton did since China
2.Airbox side camera winglet was fitted only to Hamilton’s car
3.Different exhaust outlets
4.Rear suspension . The lower wishbone joints to the car were changed again
5.New diffuser

scarbs, it looks like there are 5 pairs, ie 10 paddles, you seem to be saying that there are only 3 pairs

[connollyg]

Looking at the picture again, i can definitely see three sets of paddles, i am not sure if the wide items at the top and bottom are paddles at all.
