F1 | Aston Martin, Blandin: “Porpoising won't disappear completely”

The phenomenon of pouring featured much of 's 2022 season formula 1. With the new ground effect cars, the bouncing on the straight has been very hard for several teams and on certain circuits, just think of what happened at the Mercedes, especially in Baku, but also in the Ferrari, who, however, managed to live with it without losing performance at least in the first part of the last championship. Eric Blandin, deputy technical director ofAston Martin he said how these bounces cannot actually disappear completely with this generation of single-seaters, but there is certainly a greater understanding than twelve months ago, when everyone discovered this phenomenon.

“Porpoising will not disappear completely – Blandin said. It's something that lives in the set of these regulations: there are "tunnels" that channel the air under the car which runs very close to the ground, and there is a skirt created by the edge of the bottom and which seals the air , this combination is what makes the machine susceptible to the dolphin effect. Every car has a certain degree of oscillation, but with current regulations, due to the aerodynamic load and its variation, the bounces are more pronounced. The tools used are always the same, I'm talking about wind tunnels, simulators and software, but it all depends on how you analyze and use the data collected at your disposal."

“Simulating porpoising is complicated, there aren't many tools capable of doing it, and from a computational point of view you can't predict it with normal software, so it's not simply a matter of testing the car in a wind tunnel to see what happens, not This is how it works, it's a dynamic problem and aerodynamic loads change continuously with the car in motion. Over the course of 2022 we have deepened our understanding of this generation of Formula 1 cars, from different perspectives and in many areas, and this has allowed us to identify what is causing porpoising."
