TO Silverstone the worst was feared, but in the end Guanyu Zhou he came out unscathed from the terrible accident that saw him involved at the start of the race in one mega-carom which also involved other cars. A bang that is at the same time a praise of the heightened safety of the Formula 1 thanks to the latest legislation introduced by the FIA in 2018 (number 8856-2018). The Chinese driver has gone out without trauma from his destroyed Alfa Romeo and taken to the medical center where the absence of was confirmed fractures.
Two serious accidents at Silverstone, but the Halo saves everything
Safety cells, hardest single-seater bodies, flame resistant suits for over 20 seconds (we all remember the accident of Grosjean in Bahrain in 2020, who got out of the fire on his own in time Haas after contact with the barriers), but also helmet, belts and gloves, up to the Hans e Halo. Just the latter is what saved his life to Zhou, at risk beheading after the ‘rollover’ of his Alfa Romeo, following contact with the crazed Mercedes of Russell, who had met with Gasly to end up in a spin against Guanyu (George then immediately ran to check the health of the Chinese who ended up beyond the Abbey barriers, in turn 1). The Halo also saved the life of a Roy Nissany in the race of F2 a few hours earlier, in contact with the car of Dennis Hauger: ended up right above the head of the first, who would surely have been hit without the Halo.
This is how the Halo works
But how does the Halo work? First of all it is the curved bar placed to protect the head of pilots, introduced with the 2018 FIA regulations (already mentioned) on safety for drivers. An ad system halo connected by three arms in as many different points of the frame (on the left, right and in front the heads of the guides who race in the FIA World Championships on single-seaters). It is made in titanium and protects the rider’s head, not only preventing the headgear touch the asphalt, but also rejecting the dangerous objects that can come from the track. Here we remember the incident of Felipe Massa in Hungary in 2008, which reported a concussion for being shot in the head at over 200km / h a spring weighing about 800 grams, detached from the compatriot’s Brawn GP Rubens Barrichello. There would have been no problems with the Halo. For greater safety, theAbp in the pilots’ helmet (Advanced Ballistic Protection): a sort of protective beam made of carbon, which reinforces the shell and protects against impacts with objects larger than a bullet at high speed, that is, up to 220 grams for 250 km / h.
Pilot survival increased by 17% with Halo
In short, holy halo, as well as all the other tools that in recent years have significantly increased the safety of pilots. The latest death in F1 is that of Jules Bianchi at Suzuka in 2014. In a simulation carried out by the FIA, using data from 40 accidents realthe use of the head protection system led to a 17% increase about the probabilities of the rate of survival of the pilot. And here the confirmation is also given by the examples of Monza 2021 and the aforementioned Bahrain 2020. Last year Red Bull’s Verstappen on the Mercedes of Hamilton at the Autodromo Nazionale (Max’s wheel would have ended up on the Englishman’s head), in Sakhir two years ago the contact of the Haas of Grosjean with the barriers that caused the flames to flare up, but kept the Frenchman aware that he could thus escape from the fire, getting by right with some burns on hands and feet.
Rollbar Zhou destroyed, the FIA will investigate the causes
If one rejoices over Zhou’s saved life, however, one must ask why the rollbar Alfa Romeo’s main driver is gone destroyedwhen this is designed to withstand weight impacts seven times higher compared to that of an F1 2022 car, heavier than in the past (the minimum set is 795 kg, +43 kg compared to the 2021 single-seaters). The rollbar is the protective structure over at the pilot’s head, designed to protect the pilots just in case of overturning of your car. Just look at the pictures once the C42 of Zhou flips over, the central structure positioned just behind Guanyu’s head and at the top no longer exists. And the Chinese was only saved thanks to the Halo in front of the head. All this perhaps because of the too much weight of the single-seaters, as well at high speed of the car at the moment of impact on the asphalt, before finishing its run over the barrier. It is useless to speculate now, the Fia (the international federation) will investigate the causes of the break.
