Mc Laren MP4/24 aero-mech development in 2009

FRONT WING - SPAIN





A double profiled front wing with new endplates was tested but finally it not used for race . The new endplates featured a large exit channel at the rear while the carbon-fin was vanished .

[Michiba]

would someone be able to describe if and how those endplates interact with the wheel fairings?

Actually they do interact . The wheel fairing receives air from the outer part of the endplates ,in case of the old style , or from the under wing inner part of the endplates in case of the new style . Where this air goes ...... to an inner hole...



...to improve the brakes cooling

[Michiba]

I meant the outer wheel fairings... how does the inner wheel fairing/brake duct get air from the wing endplates?

REAR WING - SPAIN






EXHAUSTS - SPAIN

[ISLAMATRON]

I wonder why they didnt keep the open diffuser, or maybe that is an air exhaust from the sidepods and not from under the car

ENGINE COVER - SPAIN




AIRBOX CAMERA WINGLETS - SPAIN


Airbox side camera winglet was fitted only to Hamilton’s car






REAR SUSPENSION - SPAIN


Lower wishbone joints to the car were changed again

[bar555]

DIFFUSER - SPAIN


1.Extra winglet
2.Different upper central section
3.An extra little fin was added , which improves control of the drag generated by the rear tyres.

GP MONACO


Undergone changes from Spain
1.Diamonds on drivers helmets
2.Symmetric exhaust outlets
3.Rear suspension
4.Rear wheel rim shields only for Kovalainen
5.New rear wing
6.Modified diffuser



FRONT WING - MONACO

REAR WING - MONACO

McLaren have introduced a completely new rear wing for Monaco, with a big slot in the middle of the front of the main plane. The central hole, which is much bigger and more sophisticated in shape compared to the previous solution, is a concept initially introduced by Toyota at Monaco 2005 and used this season by Ferrari in the main plane, and by Red Bull and Toro Rosso in the flap, as you can see in the Red Bull rear wing drawing from earlier this weekend.

Great pics guys, thanks!

It would be really informative to compare the the pics below (front and rear of the plank) with Brawn and Red Bull cars.

Small hitch - we'll have to wait for them to crash and get craned off the track so wecan see the underside... May be waiting some time!

Great stuff bar555, thanks again.

Awesome study and collection of the MP24. Though I must point out, that this isn't a ride height sensor, but infact an optical tire slip sensor. (witness the lens on the side) It measures the lateral movement of the ground and gives a measurement from which tire deflection can be calculated.



The slot in the nose, near the "seam" where the nose comes together, is for the ride height sensor laser beams to exit, the location of the ride height sensor is inside the front of the footbox bulkhead.

From what I've been able to see the front of the RB undertray is very similar to the McLaren. I have to say the build quality of the McLaren is very poor in contrast to the RB, at the rear anyways. It loks like the undertray has been overheated and patched numerous times around the rear wheels. Not very smooth .. and the very large cutouts in front of the rear wheels might be weakening the diffuser flow. I don't think they work too well but till you can see the CFD you don't know ..

The devil of the details in all this lies in the ports for the DD. It becomes a packaging exercise, as aero often is. The Brawn and Toy were designed with DD in mind from the beginning. The RB was not but at the same time they released their DD they also came out with a new CF tranny, which no doubt has helped them work out near optimal packaging.

BTW, the front of Brawn undertray is completely different in that it does not try to build a high pressure above the undertray entry, rather it's top surface tapers off to the sidepod fronts. However Brawn have spent a lot of time creating strong vortexes along the sides of the entry. If they can find a way to get that vortex all the way back to the diffuser, that would be a nice advantage. Who knows though, till you can see the CFD on it (like that would ever happen!). All I can say is that the proof is in the result. Despite Brawn having among the lowest trap speeds in Turkey, they were quite dominate there. They have probably traded efficiency (low drag) for increased downforce. If it proves to work at a track like Turkey like it did, then you can argue that they figured it out best. IMO, look for RB to be experimenting with a revised undertray inlet area to try to emulate what Brawn has done.

Great pics guys, thanks!
