System 1 | How the Aston Martin F1 solved its development problems

The arrival of Formula 1 cars that meet the 2022 regulations, focusing more on ground effect, has led to a return to poaching.

Eric Blandin, associate technical director of Aston Martin F1, reveals that this problem will still exist in 2023 despite the regulatory changes.

“It’s not going away completely. It’s something that’s inherent in this set of principles.” he assures Blandin. “You have big tunnels that channel air under the car that runs very low to the ground and effectively has a skirt created by the floor edge that seals the air.”

“That combination is what makes the car susceptible to hunting. Every F1 car experiences some oscillation, but with the current regulations, due to the aerodynamic loading and the difference in that aerodynamic loading, this oscillation is more pronounced.”

Gone are the relationship issues

Although the infrastructure has not changed at Aston Martin, whose new factory is under construction, Blandin wants to be sure that the balance problems that arose last year will not repeat themselves.

“You use the same tools, wind tunnel, CFD, software, but it all depends on how you generate the data and how you use it. Modeling the problem is difficult. There aren’t many tools that can do that. You can’t predict that with standard software.”

“It’s not just about putting a car in a wind tunnel to see if it’s going to foam, it doesn’t work that way because it’s a dynamic problem. Aerodynamic loads are always changing.”

“Throughout the 2022 season, we have developed our understanding of the new generation F1 car in several areas, which has allowed us to identify the cause of the comeback.

How AMR22 reassured the team

Blandin explains that the problem will not occur again because Aston Martin used its average AMR22 as a laboratory, to ensure that the ratio was good again.

“AMR22 has been a laboratory. We tried hard on the track to increase our understanding and this growth in understanding was underlined by our improved performance towards the end of last season.”

“We were able to push the limits of performance with the way we were driving. It wouldn’t have been possible with the initial concept we had at the beginning of the season.”

“We are focused on making changes to this year’s car to avoid hijacking, but we can’t guarantee they will work until we test the car on the track. If we do experience this, we have a number of tools at Arsenal to combat it.”

Aston Martin F1 also predicted a possible failure

But Aston Martin has also planned measures to deal with the event that the AMR23 is not at the level expected at the start of the season.

“If we make a mistake and the car doesn’t do what we want, let’s be honest and work together to find a solution, first let’s understand why the car isn’t working and where the problems are. It’s..”

“And based on what we’ve learned, then we have to find and implement solutions to problems. There’s nothing we can’t overcome. As a team, we can overcome any challenge that we face.”

And to explain that you have to find the right balance in terms of taking risks: “There is always this risk. The F1 car is very complex, it is a mystery. But you have to trust the information you have, your experience and also your instinct, your intuition.”

“You always question things – you have to, nobody can know everything, but you have to believe in yourself. You have to believe that you’re on the right path.”
