Aston Martin: CFD data shows F1 rear wing will not hurt rules intent

The Silverstone-based squad caused a stir at the Hungarian Grand Prix when its AMR22 appeared fitted with a distinctive solution on the trunk wing endplate.

Because of an inspired interpretation of the guidelines, Aston Martin had allowed the return of a far more traditional endplate design that helped deliver increased downforce.

As the concept had received approval by the FIA, and rival teams didn’t question its legality, there is some concern that the brand new design could trigger a rise in airflow disturbance off the trunk wing.

Which could serve to scupper the power of cars to check out the Aston Martin as closely because the rules had originally intended.

However, Aston Martin performance director Tom McCullough has revealed that and also the FIA being pleased with the regulatory facet of the design, it had been also satisfied that the idea didn’t scupper the intent of the guidelines to greatly help the racing.

“It had been section of us ensuring it had been okay, as the intent of the guidelines will there be,” he explained.

“But we could actually show with simulations, that it generally does not have a material influence on that at all.

“The complete philosophy of the automobile is indeed dominant, and the wing [idea] is this type of small feature of it.”

McCullough explained that Aston Martin experienced almost a year of checking with the FIA to be certain its wing idea was totally legal before it considered giving the green light because of its production.

“We spent months, from our initial interpretation and our understanding, tooing and froing with the FIA technical department,” he said.

“Then we got the idea that once we’d been through several loops, tooing and froing, they agreed that people had satisfied all of the technical regulations.

“We then made a decision to make it, which explains why is took some time to come quickly to the track. It took almost a year from the initial contact fully approval from the FIA.

“Then, once you have theoretically got the approval, we then design and manufacture it. You then submit all of the designs pre-race weekend. And again, the FIA must make certain they’re still pleased with it, that they do. And you obtain it on the automobile.”
