Ruff a écrit:T'as l'air super calé en IFS ^^ je me renseigne sur les wing-tip et A-Pillars.
Quand à forcer le décollement, c'est effectivement chose courante (creux des balles de golf, picots sur ailes d'avion...) mais je crois pas que ça soit leur but ici non?

...In fact, they are not spoilers, which on cars force air currents down, aiding traction. The spoiler-like devices actually capture wind coming off the 40m wingsail.
There is a bend in the flow (of the wind) because of the wing," said ETNZ technical director Nick Holroyd. "All we have done is to set up a pair of vanes which capture that flow more efficiently from the sail area. That can allow a certain amount of lift out of it and we can use that to drive the boat more."
The modification to the area forward of the wingsail allows the boat's bows to be pushed down slightly when travelling upwind, minimising lift.
It also brings more performance out of the boat's jib.
The modifications are mostly directed at more upwind speed, adding to the suspicion that the battle upwind will be key in the coming finals match...

You and Pete were part of the team who wrote the Class Rule then went on to design ETNZ’s boat. What was the benefit to ETNZ?
GM: Obviously we had an insight as to why it was written the way it was. We were directed by Oracle and Mascalzone Latino to address any particular fundamental issues, like hull point speeds, weight, crew limits, that sort of thing. It was very much a big group working together for months. Like any group decision it’s never perfect. It’s a bunch of visions pushed together with certain compromises. We [Melvin & Morrelli] took a bit of a different path—we had about six of us in our office who were involved in the Rule writing, so we divided the office in half, with half the team writing the Rule and the other half troubleshooting the Rule. For example, Pete was writing the Rule, and I was on the other side challenging the Rule.
One of the jokes in-house was that we were very wary that we could write a rule and have a loophole in it that we would not be aware of, and once it got published we were particularly concerned that someone like Juan K. would read the Rule and interpret it to the point where he’d find a loophole and someone would somehow magically come out with a Rule-beating boat that somehow we had never envisioned. So we were always saying to ourselves, “How would Juan K. read this?” In the office we would force internal argument about the definition of every single line because we were trying to define something that didn’t exist, that was new.
