Halo system is jokingly called "Flip-Flops" by car fans because of its appearance - Halo is a system designed to provide full head protection for drivers in Formula Racing-based open-round races.
It is mainly used to protect drivers from flying debris and retains the unique open cockpit of formula racing. The test shows that the halo system can withstand a static load of 15 times the mass of the vehicle itself in the case of vehicle-to-vehicle collision, which can significantly reduce the potential injury.
In other words, this 7kg component can withstand an impact force of about 12 tons, which is the strongest part of the whole vehicle. there is a more vivid metaphor in F1's official description - bearing the weight of a double-decker bus. in addition, Halo can prevent the helmet from contacting the wall or obstacles in the environmental test of the vehicle.
The halo head protection system is made of titanium alloy. F1 has been introduced since the 2018 season, but it was all opposed at the beginning. Halo has increased its weight by 7kg, and its appearance design has affected the stability of the vehicle's center of gravity and the bearing capacity of the chassis, which has increased the cost of debugging and research and development of each fleet. From the perspective of aerodynamics, the halo also changed the kinetic energy of the downstream airflow, especially at the tail... Some people doubt that the installation of the halo will increase the escape time of drivers from the cockpit.
