TECH TUESDAY: How Ferrari’s Mexico City brake experiment gave us a glimpse of F1’s future

Mark Hughes appears to be like at the late-period updates released by Ferrari that had been obvious in the Mexico Metropolis Grand Prix, with technical illustrations from Giorgio Piola.

At this stage of the season aerodynamic improvement programmes on the cars and trucks have all been switched off. But that does not quit the groups from continuing to increase their knowledge.

Mexico last weekend observed Ferrari introduce a new entrance brake duct assembly, which is a prototype for the 2022 rules. The major intent of people polices is to tidy up the aerodynamic wake from the autos, developing much less disturbance in the air and producing it simpler for the vehicle powering to abide by closely and endeavor overtaking moves.

As element of this, the regulations have proficiently outlawed the blown wheels which presently direct the air from the brake ducts and as a result of the wheels in a way which improves the flow and helps generate additional downforce, but in so executing generates additional turbulence in the air passing in excess of the motor vehicle.

The 2022 brake duct with the substantially-restricted apertures as demanded by the rules.

Blown axles utilized to do this till their ban in 2019. So, aerodynamicists discovered a way of working with the wheel hub style and design to do the identical matter. For upcoming yr, the wheels must have a blanking protect which will make this practice not possible.

As section of closing off that avenue of enhancement, the restrictions also restrict the measurement of any openings there can be in the brake ducts. This provides with it a problem in making certain the brake ducts can continue to adequately do their most important job of cooling the brakes.

Mexico, with its large-altitude slender air, signifies the biggest brake cooling problem of the calendar year – and so past weekend represented a great ‘worst circumstance scenario’ experiment to see if the brakes could continue to be sufficiently cooled making use of the ’22 limitation on the dimensions of the openings. Associates from the brake provider Brembo were on hand to aid perform the experiment.

For the first practice session, Charles Leclerc ran the common 2021 brake ducts, with Carlos Sainz on the 2022 model, which had the limited openings for cooling but nonetheless the ’21 aero influence.

The workforce ended up delighted to uncover that the ’22-spec brakes behaved beautifully, with totally satisfactory cooling stages. They ended up utilised on both vehicles for the relaxation of the weekend.
