Fernando Alonso

[Adam]

So the changed the front wing first? I thought they would start with the rear one.

Thanks for the info.

I must prais Renault team for building up a car at night, and Alonso for taking to the top 3 a new car he did not even tried before, in practice session either.

[Mercedes-Benz]

Crap !!! He had some new diffuser fitted in his car today they made some changes to his car and it helped him. It is not miracle ok and also he may be less fuel

Your constant need to bash Alonso is childish, stop being such a stirrer yes, you don't like him, we get it, now move on

[icegirljenni]

but one thing they manage to do is, they manage weight problem unlike ferrari. the new diffuser somehow manage to find right setup. BUT fuel low for him, so not so win win situation but at least they sort out weight prob which ferrari unable to do so.

lets get to know about New R29 Diffuser:-

The rear of the R29 is not just some quick fix, its more detailed than previously thought of, this cant be a rushed work, I suspect renault were cunning and preparing well before they even planned to protest them. There is just too much detail and difference for this not to be a carefully thought of design.

First off the old one, well this one is from the winter testing. The recent ones in the last races features a slight change in the center line of the diffuser but nothing significant for comparison sakes just some veins for flow diversion.

From the last two races=> http://img524.imageshack.us/img524/9260/1417056.jpg

The older diffuser were wide and there was no way to increase height without breaking the rules (atleast thats what all the honest teams thought). this means a simple diffuser with less curvature upwards. This limits the amount of suction the rear gets towards the ground when air flows fast from under it to the outside.

The whole car becomes a half Venturi channel. from the front of the car to the rear of the car.

see here =>http://upload.wikimedia.org/wikipedia/commons/thumb/5/54/Venturifixed2.PNG/300px-Venturifixed2.PNG

Now here its just like basic Bernoulli's principle. When the velocity is higher at any point the pressure drops. Point 1 has more pressure than point 2 in the picture above.

So now imagine the same venturi channel as shown above and visualize the f1 car's under side and the front and rear edges forming a half Venturi channel as shown below.

The low pressure develops when the speed drops, the air under the car is moving at a faster rate which is why pressure is lower under the car. What happens because of this? The pressure form the top of the car around the bodywork exposed to the open air gets pressed down due to higher pressure above and the suction like effect from below.

Now you can see why its not only important to have a good diffuser you also need a good front end nose cone to aid the diffuser at the back. Simply bolting on something will do you no good.

The reason why the speed increases under the car is beyond the scope of this article, I shall give another article on that which will go over complete aerodynamic and fluid motion basics in detail.


Getting back to the old diffuser, we can see the edge of the diffuser on the outer most reaches are closer to the rear tyres. There is a lesser gap to the rear wheels. Also the the edge is obviously farther away from the outer reaches of the rear wing's side plates. This is shown as a reference to show how wide it is.

Now the the parallel plates that drop down is also different in its positions compared to the new one, this shows the channeling of air has to be changed, and they have done exactly that.

New Diffuser in detail=> http://img10.imageshack.us/img10/1699/122832.jpg

The new diffuser is slightly narrower and more compact to accommodate more air flow over the gaping aperture on top that forms the upper 2nd deck, This deck is designed in such a way that the air rushes into the diffuser from underneath and in the future from the sides around the sidepods into the holes that feed the 2nd deck, This forms a wing like aerodynamic structure at the same time enhances the Venturi effect. The idea to reduce the size of the diffuser's lower region is clearly to have more of that airflow to be forced into the 2nd deck.


The design is comprehensive and is not a small patch and bolt work like that of Mclaren. Renault are keeping their cards close to their chests on what going on at the factory.

Thank you, keep them coming

they are just paranoid with alonso current stage , the spanish press are giving themself something to relief by linking santander to ferrari. i seriously dont see any chance for this great man anymore to enter ferrari, after year of kimi one day, the way have to rule to vettel. i wish the spanish fans have some peace of mind

[AnnieM]

[Adam]

As an Alonso fan, I don't think that he will go to Ferrari, and honestly that's something very good for me since Ferrari is not much of my liking.

But what's probable is that Santander might sponsor Ferrari. I don't think Santander's president went to Ferrari's home just to talk about the weather.

[icegirljenni]

Santander leave mclaren because that team reputation has gone, they were just picking a right and better team. I still dont see link between santander and alonso.

[Adam]

[ScuderiaStar]

Santander will continue to sponsor Mclaren as Abbey National, the British bank they own, so they appear to have their fingers in all the pies! Common business sense, don't think Ferrari are the kind of team to be bullied by sponsors into having certain drivers!

[icegirljenni]

Spanish media will try their best to link almost all option where they see as hope for fernando. so it happen last year and happen again this year, is kind of kike use to it

[icegirljenni]

this is what happen during the autograph session last week , these photographer were so bad they climb on top wheel chair on the disable fans they could even fall on them and hurt them. alonso is real hero!

Thanks for the gif. Very good move by Alonso. Once again it proves how a good person Alonso is.
