This is the most delicate aspect as the metric that will be adopted could upset the balance of forces already defined in the first nine stages of the 2022 season. Having ascertained the existence of the necessary sensors on board the car, the next step is to define a range of vertical oscillations that can be considered acceptable to protect the health of the drivers. In particular, in the previous infographic relating to the Spanish Grand Prix we can see the absence of porpoising on the Mercedes W13 in relation to the particular road surface of the historic Catalan circuit, which does not display any roughness or dips.į1 2022: defining the “acceptable level” of vertical oscillations However, the data logs contain the value of the vertical acceleration of the cars at every single point of the track.

The representation above shows the peak of the vertical acceleration suffered by the car and the driver at each lap of the track. Amplitude of the fluctuations due to porpoising expressed in vertical g-force This is the mere graphic processing of the data detected by the accelerometer. More and more frequently, the techs illustrate different graphic talks relating to the amplitude of the aerodynamic pumping of each single-seater.

Such phenomenon, during the past few years, was perceived by the drivers only across the Eau Rouge at Spa-Francorchamps. Thanks to the accelerometer, the federal technicians and are able to monitor the amplitude of the vertical pumping from the inaugural Bahrain Grand Prix. Sensors on 2022 single-seaters and data volumes produced during a weekend by each single-seater. For several years now, a sensor called an accelerometer has been present on Formula 1 racing cars, capable of detecting lateral, frontal and vertical accelerations to which single-seaters and drivers are subject.
Much of this information is also stored on the Safety Data Recorder (SDR) control unit to which the International Federation has access.īy analyzing the data stored in the b, the FIA can check whether the components of the single-seaters have worked in compliance with the set parameters. It is a demanding task that requires the most advanced technology for data collection, their safe storage and external communication to the respective remote garages. The management of such evidence creates an enormous amount of work. Main sensors present on Formula 1 single-seaters The following infographic lists the main sensors present on the F1 cars and the relative measured quantity. In numerical terms, 300 to 400 GB are generated over a weekend in the form of data for each individual car. Basically, the concern of the such few teams lies in the fear that the good job they had done until now will be sacrificed by flawed projects.įormulaUnoAnalisiTecnica is staying true to its mission of “exploring” the technological aspects of the highest category of motorsport and will therefore describe the reference context and the possible scope of applicability of the recent provision issued by the FIA.į1: Reference technological context – AS-ISĬurrently, each single-seater houses between 150 and 300 sensors that generate millions of data every race weekend.

The (few) teams that have developed cars free (or almost) from vertical oscillations, see this provision as a “lifesaver” for teams unable to solve this side effect independently. The turmoil in the paddock is at the highest level as the FIA directive sets a dangerous precedent. Just think of the 1994 season, when all F1 cars were forced to open slits in the airscope to reduce the flow of air towards the aspirated engines, after the tragic events of the Imola GP. It is not the first time that the Federation has issued directives of a technical nature in the middle of the season. The noble intent to safeguard the health of the drivers made it necessary for the FIA to intervene, in light of the “inability” of many teams to remedy the dangerous vertical oscillations of their cars.
F1 2022: the FIA notice dated June 16, regarding the measures that will be adopted to mitigate the porpoising phenomenon, has raised a foreseeable fuss of controversy.
