What is the HALO that saved Zhou Guanyu?
Because of the appearance of the Halo system , it is nicknamed "flip-flops" by car fans - HALO is a system designed to provide drivers with sufficient head protection in open-wheel events dominated by formula racing. It is mainly used to protect the driver from flying debris and retains the open cockpit unique to formula racing.
The Halo system adds a titanium alloy protective ring in front of the driver's cockpit.
The Halo system is nicknamed "flip-flops" by car fans because of its appearance.
Tests have shown that the HALO system can withstand 15 Static loads that are times the vehicle's own mass can significantly reduce potential injuries. In other words, this 7-kilogram component can withstand an impact of about 12 tons and is the strongest part of the entire vehicle. There is a more vivid metaphor in the official F1 description - bearing the weight of an double-decker bus .
In addition, during vehicle-to-environment testing, HALO can prevent the helmet from coming into contact with walls or obstacles. The HALO head protection system is made of titanium alloy material and was introduced to F1 starting from the 2018 season. However, there were all objections at the beginning. Because HALO adds 7 kilograms of weight, and affects the stability of the vehicle's center of gravity and chassis endurance due to appearance design reasons, it increases the costs of debugging and research and development for each team. From an aerodynamic point of view, HALO also changes the downstream airflow, especially the kinetic energy at the rear wing... Some people even suspect that adding HALO will increase the driver's escape time from the cockpit.
At that time, the manager of the Mercedes-Benz team complained, "If I have the opportunity, I would like to use a saw to saw off HALO." Drivers including Alonso also expressed their dissatisfaction with HALO. Habits, considered dispensable. However, many accidents on the track have proved that HALO is extremely important to motorsports.
