Scuderia Ferrari SF71H

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

How come the startup smoke was only picked up on day 7 of testing?
Actually, I read about this throughout testing, and with regards to all Ferrari powered teams. I think it was only filmed because Ferrari prepped the cars for their race sims outside of the garage.

It was picked up from almost the first day, you can find posts about it if you go back and look for them. However, a lot of the content on this forum was concentrated on the low drag/ducted mirror debate.

Ah right. Yeah, everyone did seem to become obsessed with those accessories.

So are they flowing the oil exhaust over the diffuser?
And using the outlet on the rear crash structure to assist in rapidly heating the air behind the lower part of rear wing?

The secret behind Ferrari's floor tunnels by Giorgio Piola
Ferrari's Formula 1 car grabbed attention in pre-season testing thanks to the appearance of new bodywork tunnels exiting alongside the gearbox. Such was the intrigue that they even prompted some wild conspiracy theories about double diffusers, but this gossip was wide of the mark. The reality is that rather than being something to get around the rules, these channels are instead the latest step of a clever design path that Ferrari has been working on in recent seasons. Since 2016, Ferrari began working on the idea of an extra channel on top of the diffuser area to help direct airflow. This trench was previously left open, but for this year it has taken the step of covering it to increase its power. And the extra push in this area is directly linked to Ferrari's decision to increase the wheelbase of its car this year. Although last year's SF70H was in a class of its own on high-downforce tight and twisty tracks like Monaco and Hungary, it lacked in balance and aerodynamic efficiency for more flowing circuits. Increasing the wheelbase for 2018 – from 3550mm to 3678mm – allows the team to better manage airflow across the car's surfaces, and especially at the rear of the car, without it forcing the need for high-drag wings. As Giorgio Piola's drawing shows (above), Ferrari has achieved its longer car by moving its front wheels forward a little bit, but its rear wheels have been shifted backwards much more. As well as lengthening the sidepods, the team has also moved the radiators and power unit forward to free up some space at the rear. This has the benefit of allowing the team to run ultra-tight packaging at the rear of the car. But as well as very narrow sculpted bodywork at the rear, the design has opened up the chance to exploit more the airflow around the diffuser. This has manifested itself in the channels that run right alongside the wall of the new gearbox, which help accelerate airflow to help feed the diffuser. Rather than the trough being left exposed as it was in the past, Ferrari has now shrouded it with bodywork in order that the flow making its way around the coke bottle region has contours to follow. This bodywork should provide a protective barrier for the flow, helping it to navigate the region more effectively over a wider number of operating conditions. The team's hope will be that the SF71H delivers its peak performance more consistently at different tracks, and is especially better on the longer flowing circuits where Mercedes excelled in 2017.

Technical analysis: here is the Ferrari secret in the SF71H rear axle

Thanks to Giorgio Piola's drawings, we are able to show you what the work done by Ferrari technicians has done to make the most of the increase in wheelbase: the "channel" grazing the gearbox has been exaggerated to produce more aerodynamic load.

Why has Ferrari lengthened its pace like Mercedes, despite having a very agile and agile car last year?

The answer is simple: because the technicians of Mattia Binotto have tried to increase the aerodynamic load with the car body, in order to reduce the incidence of the wings and be faster at the speed trap and in the qualifying lap in the attempt to challenge the arrows silver.

The statement is quite clear, but it is interesting to try to find out how they tried this result in Maranello.

The SF71H has lengthened its pace with a small displacement of the front wheel forward (the radiators' mouth has also been anticipated because there is no longer the flow conveyor separated from the sides) and with a more marked growth in the rear axle.

Thanks to this design choice the radiant masses and the power unit are moved forward, so in the so-called Coca Cola area the Ferrari has become very narrow, having a bottom surface that creates one of the biggest sidewalk among those seen on the 2018 cars, so much so as to bring the lower part of the body into contact with the wall of the new gearbox, which is also less wide than that of 2017.

A very accurate aerodynamic study, carried out first at the CFD and then in the wind tunnel, has allowed to exaggerate the "channel" that the Cavallino technicians had created in this area of ​​the fund.

Since 2016, Ferrari has been developing a flow that touches the final part of the bottom: initially a sort of channel was created that began well before the elbow of the extractor profile and vented to the sides of the rear deformable structure, exploiting the keel shape of the tail, behind the transmission, to go to energize the micro flaps that the regulation allows to emboss the outlet edge of the speaker.

The aerodynamics of the Cavallino, Enrico Cardile and David Sanchez, in the last two years have worked hard in this area of ​​the Red to take the maximum advantage possible from a solution that does not cost in terms of resistance to progress, but can give a significant increase of the down force: above, we observe the version of the "channel" seen at Abu Dhabi 2017, while in the drawing below you can appreciate in yellow what was the increased surface compared to 2016.

This year the SF71H is able to exaggerate the passage of grazing air to the transmission wall: to obtain valid results, they worked elbow aerodynamic, canvasists and motorists. It was a not very visible intervention, but important and very demanding (and as such not easily copied during the season).

The new packaging of the 062 EVO power unit made it possible to clean up what was considered one of the strategic growth areas of the Red Army and, it seems, that the results were also seen on the track in the tests of Barcellone with the two Ferraris at the top of the table of the final times.

The increased air flow in the "channel" therefore required a change also at the end of the SF71H: in the drawing, below, in fact, we note how a megaphone-shaped bulkhead has been introduced that has the task of expanding the threads, improving its extraction.

Someone mistakenly spoke of the existence of a "double bottom", which is banned by the FIA ​​rules: the solution adopted by the Red is perfectly legal and testifies how we try to reproduce some effects with great imagination and originality.

The question that the fans of the Cavallino do is: just to beat the Mercedes?
Where can we see Giorgio Piola's drawings?

Can this be considered as a kind of a blown diffuser?
Wouldn't they need a significantly greater volume and velocity of flow for that, and for it to actually be blowing the diffuser?
you have to compare it with the standard solution
therefore with a wall that has probably separation due to the expansion of the sidepod closin toward the middle line

Tunnels or ducts like these have been made in various guises in the recent past.

RBR 2013ish ducts were similar I think... Maybe not as fully enclosed, but their over/under ramps look to serve a similar purpose.

It seems to me, that from Seb onboard record lap, he is able to take T9 flat out. Can we take this as something like car performance indication, or, do you think other cars from top 3 teams are able to do that too??? SF71H seems to heave mega grip from that video.

In one of the interviews during testing (with Costa I think) there was mention that Hamilton had been flat through there too. Likely that the top three (or more) are all able to do it this season.
