"I'm fine, I'm lucky I can still stand here", after experiencing the thrilling moment of F1 Uk," Chinese driver Zhou Guanyu posted on social media to report that he was safe.
On the evening of July 3, Beijing time, Chinese driver Zhou Guanyu was involved in a serious collision accident during the starting stage of the F1 UK race, and his car flipped out of control and rushed out of the track at high speed, with serious damage to the body. Fortunately, Zhou Guanyu escaped from death, and there was no major problem.
After confirming the safety, Zhou Guanyu said that Halo saved him, and "the Halo system has made a contribution again" also instantly became the first hot search.
What exactly is the Halo system?
Nicknamed "flip-flops"
Can withstand the weight of a double-decker bus
The Halo system is a safety system that provides full head protection for racers driving racing cars at high speeds. In 2018, the International Automobile Union required all F1 fleets to install the system.
Halo is made of titanium alloy material and installed on the cockpit of a racing car, and its image has been ridiculed by netizens as a "flip-flop". Its constituent elements include the front of the center, called the "V transition", the metal tubes around the cockpit, and the mounting fixation of the rear.
Since halo affects the aerodynamics of a car and increases its weight, many teams have been carefully designed under safety standards.
The application of the Halo system has changed the once open racing cockpit into a more secure semi-enclosed type. Compared to the seemingly safest fully enclosed cabin, the Halo system both avoids visual distortion on the rider by the windshield and provides maximum head protection for the rider.
Tests have shown that the Halo system can withstand a static load of 15 times the mass of the vehicle itself in the event of a vehicle-to-vehicle collision, significantly reducing potential injuries.
In other words, this 7 kg weight component can withstand about 12 tons of impact force, which is the strongest part of the whole car. There is a more figurative analogy in the official F1 description: bearing the weight of a double-decker bus.
The introduction encountered a lot of resistance
But it has saved many drivers
In fact, when Halo first introduced F1, it was met with a lot of opposition.
Due to the increase in weight of 7 kg by Halo, the stability of the vehicle's center of gravity and chassis endurance due to the design, the commissioning and research and development costs of each fleet were increased.
From an aerodynamic point of view, the Halo also changes the kinetic energy of the downstream airflow, especially at the rear wing. It has also been suspected that the addition of Halo would increase riders' escape time from the cockpit.
At that time, the manager of the Mercedes-Benz team complained, "If I have the opportunity, I want to use a saw to see off Halo." Riders, including Alonso, also expressed their unaccustomedness to Halo, believing it was dispensable.
But since the 2018 season, Halo has saved multiple racers in several near-fatal incidents:
In the Belgium 2018 season, Leclerc's car was hit by another car, and he was protected from life-threatening protection by Halo.
In the 2020 bahrain season, the car driven by Romain Grosjean suddenly lost control and crashed into the barrier, the car disintegrated and burst into flames in an instant, and Grosjean, who had not supported the Halo system, finally escaped in a thrilling escape, only slightly injured.
At Monza in the 2021 season, Hamilton collided with Verstappen, and Verstappen's car was lifted into the air by Hamilton's car, and if it were not for the Halo system, Hamilton could have been life-threatening.
Despite the resistance, numerous on-field accidents have proven that the Halo system is incredibly important to motorsport.
