On July 3, Beijing time, the Formula 1 British Grand Prix began to compete at Silverstone.
In the initial stages, China's Zhou Guanyu collided with Britain's Russell's car. After the impact, Zhou Guanyu's car flipped over 180 degrees, rubbing on the ground and sliding out of the track with a spark of lightning.
The hearts of everyone at the scene immediately tugged, and they were all uneasy about Zhou Guanyu's safety, fortunately, there was no danger, and Zhou Guanyu was not seriously injured.
Zhou Guanyu Weibo
Zhou Guanyu sent a Weibo message at the first time after the accident to say that he was fine and thanked everyone for their concern.
Zhou Guanyu also highlighted "Halo" in this Weibo, saying that thanks to "Halo" to survive, and then the related topic "Halo system has made a contribution" appeared on the hot search.
Halo system on the hot search
What exactly is the "Halo" system?
This is a type of protection device used in open-wheel racing and was first conceived in 2015.
French driver Bianche
During the 2014 F1 Japan War, 24-year-old French player Bianchi suffered a head injury in the accident and eventually died. The Halo system is a protective device that was proposed after the Bianchi accident to protect the driver.
In 2018, the International Federation of Motor Sports (FIA) decided to make it mandatory that in Races in Formula One and Formula II, participating vehicles must be fitted with a Halo system to protect the driver's head.
Halo system
From the current public data, halo weighs about 7kg, the main material is titanium, the manufacturing cost is about 84,000 yuan, and it is manufactured by the manufacturer designated by the International Automobile Sports Federation FIA.
The Halo is mounted on a frame in front of the rider, bypassing the rider's head from both sides, with the rear end fixed to both sides of the cockpit. Because of such a structure, fans jokingly refer to the Halo system as "flip-flops."
The Halo system resembles flip-flops
Don't underestimate this 7kg-heavy "flip-flops", it is the strongest part of the whole car. We take a closer look at the Halo system, the prism in the middle of it is made of reinforced aerospace-grade titanium, so it has a super high impact resistance, ensuring that it will not be flattened or broken in the event of an accident. The distance between the three prisms is also carefully calculated to prevent objects from passing through the void and damaging the rider. The top part acts as a support frame after the vehicle rolls over, which can greatly protect the driver's head.
F1 officially claims that it can withstand 12 tons of impact force, which means that the Halo system can withstand a double-decker bus.
The Halo system's extraordinary impact resistance can protect the drivers from high-speed objects in the event.
According to a data analysis of 40 real accidents released by the International Automobile Sports Federation, the Halo system can improve the survival rate of racing drivers in major accidents by 17%, while after the impact, the structure of the Halo system is almost undamaged, only some scratches on the surface.
The Halo system is extremely resistant to impact
And the Halo system is not the first time it has been successful.
In the 2018 F2 barcelona race, Japanese driver Reiyuki Makino collided with another driver's car, and both cars slid off the track. Fortunately, under Halo's protection, the rider's injuries were not serious.
Afterwards, Makino tweeted to thank the Halo system for protecting him.
Makino Renyou tweeted
At the 2020 F1 Bahrain Grand Prix, the car driven by driver Gross crashed into the protective fence, and then the body quickly ignited a fire, and it was the Halo system that not only protected Gross's head, but also supported him with an escape space, allowing him to quickly escape the fire.
The rider quickly escaped
For now, though, the Halo system does improve the safety of riders. But when the International Motor Sports Federation first proposed a mandatory installation, it was met with a lot of controversy.
Flip-flops have been criticized
The first is that the weird shape similar to the "flip-flops" is much ridiculed, and the prism in the middle affects the rider's line of sight. Even Gross was one of the "naysayers" before the accident, but after being rescued by the Halo system, his thinking changed, saying publicly: I did not support the Halo system before, but now I am grateful that it was introduced to F1 cars, without which I might not be able to stand here and talk to everyone today.
Hans device
Hans device
In addition to the Halo system, there is also a HANS device, which is also used to protect the driver's head, these are measures for the personal safety of the racer, and there are many designs for safety considerations in the racing car, such as the fuel tank is generally made of Kevlar material flexible fuel tank, the cockpit of the F1 car is generally carbon fiber material, strength, hardness, load-bearing and other aspects have high requirements.
Carbon fiber body
Therefore, the wonderful games we see on the spot or on TV in just a few minutes reflect the crystallization of countless black technologies.
Sincerely thanks to the progress of science and technology, not only changed all aspects of life, but also enriched our spiritual life.
Also thank you very much to the friends who saw this, thank you for your support.
