Actually you want to use high nose so the underside and splitter area divert airflow out the sides of the car to *minimize* the airflow under the car and make the diffuser create a lower pressure area under the floor.WhiteBlue wrote:I think the philosophy today is making the tub and nose as high as possible and clearing the airspace under it as much as possible. That gives you the best chance to pull as much air as possible under the car to feed to the diffusors.

That is possibly why the RedBull uses two fins on the underside of the nose.BreezyRacer wrote:Actually you want to use high nose so the underside and splitter area divert airflow out the sides of the car to *minimize* the airflow under the car and make the diffuser create a lower pressure area under the floor.WhiteBlue wrote:I think the philosophy today is making the tub and nose as high as possible and clearing the airspace under it as much as possible.

Red bull are actually one of the last to do these fins, first done in China this year. I think I saw them first on last year's Renault but not sure. In any case they just help manage/isolate under nose airflow from the rest of the car. But I would say this area of the car is where a lot of attention has been paid recently to improve diffuser/undertray performance.gilgen wrote:That is possibly why the RedBull uses two fins on the underside of the nose.
Yes, that makes more sense in terms of description. But the goal is still high air flow flow in the nose section even if you want to divert it away later. I wonder how that drooping nose was supposed to achieve that. The straighter high noses seem to be a simple solution for the task.BreezyRacer wrote:Actually you want to use high nose so the underside and splitter area divert airflow out the sides of the car to *minimize* the airflow under the car and make the diffuser create a lower pressure area under the floor.WhiteBlue wrote:I think the philosophy today is making the tub and nose as high as possible and clearing the airspace under it as much as possible.

The nose is the front crash structure. The only part they can touch is the wing and the wing struts.n smikle wrote:On the nose; I guess a team can try to design their front crash structure as a separate part form the the nose cone. I think that is how they do it for some of the LeMans cars.
I imagine that testing on the nose was related only to the nose area, thus they may have found a little more front downforce with that layout and since that's what they were looking for they settled on that design.WhiteBlue wrote:Yes, that makes more sense in terms of description.
