Formulation 1, 2023: rule change after Zhou’s horrific accident?

“Halo saved my life,” Guanyu Zhou mentioned on Twitter after his horrific crash at Silverstone on July 3, 2022. Within the first stage, the Alfa Romeo driver collided with George Russell’s Mercedes, which turned the Chinese language. Nearly with out braking, Zhou’s automotive skidded down the asphalt till it left the gravel mattress and hit a guardrail. Miraculously, no drivers, spectators or marshals had been injured.

However the true depth of the scenario grew to become clear solely on the planet of Formulation 1 after the accident. Whereas the secondary crash construction, higher referred to as the halo, withstood the stress, the first crash construction (the roll bar) collapsed into mud. The photographs of the automotive later confirmed: There have been just a few centimeters between Zhou’s head and the asphalt.

Alfa Romeo: Technical director requires coverage change

“We now have been working with the FIA ​​for the reason that day of the accident to recreate the accident and check it as a lot as doable,” mentioned Jan Monchaux, Technical Director at Alfa-Sauber. “It isn’t a straightforward activity for the forces concerned.”

In contrast to different groups, Alfa Romeo didn’t share the G forces appearing on their rookie driver throughout the affect. “Within the meantime, the FIA ​​has requested all the opposite groups to report on numerous comparable conditions involving the power of the roll bar with a purpose to discover room for enchancment,” mentioned Franco-German.

Even earlier than the FIA’s evaluation was accomplished, one factor was sure about Monchaux: new security requirements had been wanted within the premier class. With out going into an excessive amount of element, the forces that need to be obeyed by the foundations – you may have a sure vectoring, it’s a must to use the power in entrance and behind the roll bar – should not sufficient in accidents like this the place the automotive skids. . The forces are horizontal there, probably not a vertical power. There might must be modifications sooner or later,” defined the person from Alfa Romeo.

FIA: The roll bar should move this check

The FIA ​​has already introduced that it intends to sharpen the roll bar as early as 2023. However what hundreds does the present era of bars have to resist with a purpose to obtain the FIA’s blessing? The reply to this query could be present in Article 13.3 of the technical laws of Formulation 1. The roll bar, known as the ‘Principal Roll Construction’ within the laws, should move a collection of static endurance checks.

Whereas the roll bar is connected to the survival cell, the construction should stand up to a power of 60 kilonewtons within the lateral course, 70 kilonewtons within the longitudinal course and 105 kilonewtons within the vertical course for ten seconds. 105 kilonewtons equals about 10.7 tons! The construction shouldn’t be deformed by greater than 25 mm. As well as, no structural harm ought to happen greater than 100 millimeters beneath the floor.

As well as, the groups should submit detailed calculations that present that the roll bar can stand up to the identical longitudinal hundreds throughout the ahead motion.

However as Zhou’s accident confirmed, this excessive stress check shouldn’t be sufficient. “We are going to get a brand new, further facet stress check or one thing like that, which we’ve to move in 2023,” McLaren man James Key suspects. Time is of the essence, the groups need to clear this week earlier than the summer season break.
