    FIA TAKES STEPS TO REDUCE PORPOISING IN THE INTERESTS OF SAFETY
    16.06.22

    Following the eighth round of this yearrCOs FIA Formula One World Championship, during which the phenomenon of aerodynamic oscillations (rCLporpoisingrCY) of the new generation of Formula 1 cars, and the effect
    of this during and after the race on the physical condition of the
    drivers was once again visible, the FIA, as the governing body of the
    sport, has decided that, in the interests of the safety, it is necessary
    to intervene to require that the teams make the necessary adjustments to reduce or to eliminate this phenomenon.


    A Technical Directive has been issued to give guidance to the teams
    about the measures the FIA intends to take to tackle the problem. These include:

    1. Closer scrutiny of the planks and skids, both in terms of their
    design and the observed wear

    2. The definition of a metric, based on the carrCOs vertical acceleration, that will give a quantitative limit for acceptable level of vertical oscillations. The exact mathematical formula for this metric is still
    being analysed by the FIA, and the Formula 1 teams have been invited to contribute to this process.

    In addition to these short-term measures, the FIA will convene a
    technical meeting with the Teams in order to define measures that will
    reduce the propensity of cars to exhibit such phenomena in the medium term.

    The FIA has decided to intervene following consultation with its doctors
    in the interests of safety of the drivers. In a sport where the
    competitors are routinely driving at speeds in excess of 300km/h, it is considered that all of a driverrCOs concentration needs to be focused on
    that task and that excessive fatigue or pain experienced by a driver
    could have significant consequences should it result in a loss of concentration. In addition, the FIA has concerns in relation to the
    immediate physical impact on the health of the drivers, a number of whom
    have reported back pain following recent events."

    In all seriousness though, if we assume that cars such as the Merc have been run
    in a mechanically bouncing manner as that is the fastest way to run the car, surely all this will do is hamper teams like Merc further compared to teams like
    RBR which appear to have less of the same issue.

    I don't have a problem with that, seems like they have listened to drivers saying this is going to cause injury & basically said they cant run a car
    in a way that is likely to injure the driver.

    porpoising they will just be slower. Of course this would write off the
    season for some teams and promote others."

    Indeed, but that is as it should be. Mercedes seem to have designed a car
    that is only competitive when it is bashing the living daylights out of its drivers. It is right that the regulator, i.e. the FIA, should introduce measures to protect the drivers when the teams, in the interests of competitiveness, might be reluctant to do so. As I understand it the
    problem is quite easy to alleviate (presumably by raising the ride height
    or similar measures) but it would be grossly unfair to teams that have got
    it right to introduce mandatory changes that would disadvantage them.

    Having said that, it is slightly irritating that, in the past, RBR have succeeded in getting various MB innovations banned (rCLparty moderCY, DAS etc) because they couldnrCOt match them or hadnrCOt thought of them.

    And therein lies the solution to the problem. Resurrect a previously
    banned tech which should never have been banned in the first place
    and repurpose it. Turn the bathtub and driver into an inertial mass
    damper!

    I thought of the idea whilst watching this race in the pub, so it might
    be a terrible idea, but steadycams work, and Taipai 101 hasn't fallen
    over yet despite a 7.1 and plenty of high 6s, so IMDs definitely have
    utility.

    One of the things I really hate about modern F1 are all the times the
    FIA bans things that were clearly legal at the time the teams devised
    them; especially when they stretch the definition of something
    ("affecting the aerodynamic performance of the car" is a very common
    refrain in this).

    This blunts their edge when they actually really do need to consider a
    change in regulations such as the one facing them right now.

    The driver's health and safety are both truly at risk if the car is
    hammering up and down too hard.

    Just how hard that is... ...I'm not qualified to say, but just like
    other sports that have woken up to the dangers of head impacts (North
    American football, hockey), there quite clearly IS a "too hard".

    And yes: every team out there knew that there was going to be a certain
    amount of porpoising that they weren't going to be able to accurately
    model in CFD or test in their wind tunnels...

    ...and if some teams can't get their porpoising under control to meet a
    change in the regulations... ...well that's just too bad for them.
