There have been some pretty wacky ways described for the possible operation of DAS, but if we 'Ockham's razor' this, it wouldn't be that difficult to just manually move the rack fore and afterikejw wrote: ↑Mon Feb 24, 2020 9:52 pm
"10.4.5 Power steering is allowed but such system may not carry out any function other than reduce the physical effort required to steer the car and must allow the steering to continue to function when all hydraulic and/or electric power is shut down."
Since DAS is part of the steering Mercedes needs to show that their drivers can do the toe in and toe out as efficient without the help of power steering, otherwise it should be deemed a safety hazard and forbidden.
Imagine a car with power steering and a malfunction( Senna comes to mind), then uncapable to operate.
DAS might not even use use power steering, hydraulics. Then all of the above is forfeit.
Why Parc Ferme? They change tons of stuff all the time while in 'Parc Ferme'.
Surely that would be considered moveable aero? Not to say they're not doing it, but that car would have scrutineers all over it and I dare say every other team has lodged a protest by now.
Contrary to what have been said the steering wheel is not pushed or pulled by the driver, the steering wheel movement (up or down/towards or away from the driver) is actuated by the driver via a push button.Sieper wrote: ↑Mon Feb 24, 2020 1:33 pmWhat I don't understand is any moveable aero is forbidden.
With toe-in your wheels have a larger frontal aero surface then with toe neutral. So by moving the wheels to toe-neutral you are having less of an aero impact and as such it is moveable aero. They way how you achieve it does not really matter anymore. The fact that you have a way of controlling it to your suit is enough to call this moveable.
Then, to make matters worse, there is the way you control it, yes you use the steering wheel, but not to steer, just to actively control the aero frontal impact of the front wheels. When pulling the steer toward you and when pushing it away you are not steering at all, you are moving in a straight line. The only purpose is to change toe-in and with that frontal aero surface is reduced.
I highly doubt that.
Also, if the driver can activate the adjustment with a button, then why they have designed it that the steering wheel is moving at all? What is far more likely is that the driver has to press a button to simply unlock the mechanism.10.2.2 Any powered device which is capable of altering the configuration or affecting the performance of any part of any suspension system is forbidden.
Yeah but without DAS's gains the possible compromises they've made in structure or the additional weight of the system might even lose them some time, wouldn't it?
it's supposed to be against the rules, but they accidentally wrote it so it only applies if the steering wheel is fixed
