Mclaren jerez test new aero

Post

Ok, mclaren was running new aerodynamics in jerez. Take a look at the hot air outlets. I'm not sure whether they're new or not, since the photographers managed not to take a single picture of the tops of the sidepods of the new mac during it's first test earlier this month. First of all there is a big gaping hole. It's gigantic. The pipe thingy is a ramp to the winglet. Very interesting, leading the air under the winglet, on to the flip-up. Then there are those holes around exhaust gas outlets. But most interesting of all is that small hole under the tiny west logo... what is it's purpose? best seen in the last picture
Man, they sure have put some holes in their car, that's for sure.

Well I must admit that the best looking car on the grid just got better looking, but as for performance I remain doubtful. The MP4/19A was supposed to be the car that leveled the playing field, and look where it's ended up. As has been proven recently, testing times mean little. I do have hope though that this evolution will make a big impact.

Look at the last picture. What is that you see in there? Don't think it's the radiator, otherwise it would be in rather weird position. Yup, judging from the first picture it is nearly vertical. Weird.
Or then again, could it just be the floor? :D

The current trend for radiators is to have 2 or 3 small rads joined together in configurations like this...

So the could be a top piece of radiator....or an oil cooler....

It's quiet a bit funny, the intake radiators are getting smaler but
the air outlets are placed everywere around the car. :?
But where do they get the air for all these outlets :?:

Something off topic
I'm trying to make some drawings of the MP4 19 but I need pictures
of the car and can't get them If right click is not possible in the forum. :evil: :twisted:
So if somebody is interested in detailed drawings of Mclaren cars make it please possible to get the needed pictures. :!:

don't forget air expandes quite a big when heated.....put a closed bottle under hot water....you'll see it expands slightly....if you put the same bottle in the freezer you'll see it contracts.....so the mass of air might be the same...but the volume o air is diferent.

Same thing with F1 cars...though the intake is very small it's designed to have a certain air flow /mass to go through the intake....when it's heated it expandes...that's why it seems that there are more outlets then intakes.

Ok, you are right.
But does it makes sense to instal so many smal outlets.
It hink it's easier to instal a few tall outlets on a good possition, because
all these outlets must have their own chanel under the bodywork.
Maybe in front of the rear wing or the smal wing on the sidepot.
Remember Kimis engine blowup at the Nürburgring, the smoke was only
under the rear wing.
The exaust gases produce a litle bit extra downforce at this possition.
