McLaren F1 “There is no clear answer that could avoid the porpoising phenomenon”[F1-Gate .com]

McLaren F1 says it has no clear explanation as to why it was able to avoid the porpoising phenomenon that plagued other teams in last week’s F1 Barcelona test.

Last week, the F1 team began their first run on a new generation 2022 F1 car in pre-season testing, but many drivers were amazed at the bouncing phenomenon they experienced when the car reached straight and high speeds. ..

Solving this problem has been a major headache for some teams. Mercedes F1 will run with additional reinforcement stays on the floor, and Alfa Romeo says there is no suitable solution until the next test in Bahrain.

However, the McLaren F1 encountered few problems, except that it caused problems when the aerodynamic platform was fitted with some test parts.

James Key, McLaren F1’s technical director, says the team isn’t completely unaffected by the porpoising phenomenon, but it doesn’t cause any particular headache.

“There were some test parts that seemed to promote the porpoising a bit,” said James Key.

“But when I removed them, it decreased and I was able to fix it aerodynamically well.”

“So far, where we are wasn’t really a topic for us. Of course, we’re not saying that further development won’t bring it back. We’re suffering a bit, It’s neither a big concern nor a big distraction for the driver. “

James Key confesses that the McLaren F1 did not wisely create a car that specifically addresses the porpoising phenomenon, but it is also a complete Magre that proved to be very stable in the MCL36’s design. But I don’t think it was.

“We want to make people believe they are very smart, but in reality it’s very difficult to simulate,” explained James Key.

“It’s related to tire stiffness and the car’s heave mode. If it’s in harmony with the chassis, you’ll see it actually disappear when you get the natural frequency. There’s also a front mass.”

“So I don’t think it’s completely lucky. I think it’s a bit of a car stability, and how well the car can be loaded under different ride height conditions.”

“But if I say it’s by design, I’m lying. I think it’s a phenomenon that we all get used to with the trucks that drive these cars. It’s resolved over time. And hope you can learn how to get rid of it as a problem. “

However, James Key believes that the porpoising phenomenon may not be completely eliminated by the team, and drivers may need to deal with it well on certain tracks.

“Because it’s a ground effect car, I think that such a unique ground proximity reaction can always occur,” James Key added.

“I think it’s unique, and that’s why we’re looking at it now, but I think we’ll learn to manage it.”

“These cars still have a lot of discoveries and a lot to learn. I don’t think we can eradicate this phenomenon because it’s physical, but in terms of managing it, it’s a little bit. After the development work, I think the problem will be much less and it will be an issue. “
