The FIA ​​introduces new tests for the rear wing: the end of “Flexwings”?

( – The FIA ​​has focused on the topic of “Flexiwings” again since Barcelona and will introduce new rear-wing tests ahead of the French Grand Prix in order to prevent potential vulnerabilities. The issue was brought up in Spain when Lewis Hamilton accused Red Bull of having a bent wing.

This should be tilted backwards on straight lines to generate a higher top speed. On turns, it returns to the starting position in order to ensure the greatest possible downforce.

Red Bull Team Leader Christian Horner confirmed that the wing had successfully passed all necessary tests: “The cars were of course extensively tested. There are rollback tests and various other tests that they have to pass. The FIA ​​is absolute and the British said, ‘Satisfied with the car.

In the meantime, however, the FIA ​​has written a letter to all Formula 1 teams stating that there are designs that have passed the current static tests, “but which still exhibit widespread deformations when the car is in motion.”

Therefore, the International Automobile Federation (FIA) announced that it will activate a provision in technical regulations allowing the introduction of new tests: “The FIA ​​reserves the right to conduct further stress / deformation tests on any part of the bodywork that is suspected of being involved in the change while the vehicle is in motion,” “Article 3.9.9 of the Technical Regulations states.

The notice also lists a number of new tests that focus on deflecting the rear wing back when driving at high speed.

Currently, the wing may not curve more than one degree horizontally or three millimeters vertically when subjected to certain loads. The new tests include a one-degree limit for rotation on a vertical axis to the mainboard when two background and horizontal forces of 750 Newtons are applied at a specific location.

Another test allows 1,000 newtons of vertical and downforce with only one degree of rotation.

Since some teams may need to rework their rear wings in order to pass the new tests, the FIA ​​has decided the tolerance phase. Therefore, current designs are still used in racing in Monaco, Baku and Turkey (If the Grand Prix is ​​held) it is legal before the exams take place starting June 15th.

The first race after that will be the French Grand Prix at Le Castelet on June 27th.
