Ferrari’s F1 Racecar: The Technical’s

Ferrari’s return to form at the US Grand Prix after a period in irons may have come too late to save Sebastian Vettel’s title campaign, but the removal of recent updates at least showed the team where the problem areas have been lately.

“You can see it as good news but you can also see it as bad,” said Mr. Vettel following the United States Grand Prix. It is good that the car is fast again, he explained, but bad that it had taken a return to a specification used three months ago, suggesting that The Scuderia’s development program had somehow gone awry.

At COTA a new barge board and floor were brought and tried on 1 car during Friday’s FP1, but that update was removed for the rest of the weekend. This was a modified version of the new floor introduced in Sochi but removed in Suzuka in favor of the standard floor. The barge board and floor work together as 1 update.

The new barge board has 2 extra ‘mushroom’ vortex generators aft of a revised and more intricate set of guide vanes. These vanes carry more curvature than the older-spec barge board. The vortex generators further energize the airflow travelling along the outer edges of the floor. The revised floor that was tried and discarded in Austin, the standard floor that was qualified and raced on both team cars.

Comparison of the 2 floors shows how much more intricate the arrangement of slots and vanes are in the new version.

Management of the airflow between the upper and under surfaces of this part of the floor is highly sensitive. The slots help create vortices on the outer edges of the underfloor that seal the underfloor off to increase the negative pressure, which in turn increases the speed of the airflow coming through the central part of the underfloor and thereby increases down-force.

The vortex generators on the new barge board suggest that the Ferrari aerodynamicists are trying to increase the speed along the upper surface of the floor so that when it meets the slots and interacts with the underfloor flow, the power of those underfloor vortices is increased, thereby giving a stronger sealing effect.

This has been concurrent with a change in the shape of the slots forming those vortices, and a series of new outward-pointing vanes around them. This suggests that an attempt is being made to more efficiently turn around any rear-tire airflow not sucked through the slots.

The vanes ahead of the lateral slot at the rear just ahead of the tire have also been re-aligned. Air will be accelerated through this slot, further directing it away from the tyre, in this case inboard – and from there will be used to help energize the flow around the exit of the diffuser.

These changes will have been guided by Ferrari’s studies in the wind tunnel and CFD, but have not worked as simulated. This has followed other recent developments that have been subsequently discarded including a rear wing and rear suspension introduced at Singapore but removed, also since Suzuka. A new front wing introduced in Sochi has remained on the car since.

Although Ferrari’s competitive return to form is great news for F1, The Scuderia development team having identified the areas where its previously mysterious loss of form originated, will now be working hard to understand just why this particular area of development has not worked as simulated. It will be particularly Key in the development of next year’s car that this problem is understood.

I remember when things were not this complex, but that is true of almost all things these days.
