sevor of moveable front wing

[Scania]

how much power & torque the sevor motor need?

[mycadcae]

Using a servo, controlled by a dial on the steering wheel, the wing can be moved by up to 6 degrees and this affects the amount of downforce the front wing produces. It can be used twice per lap and will be used extensively during the race.

It is a difficult thing to get right, without movement you don’t want from the wing, but it counts for a lot and it’s something Ferrari were the first to master with the 2010 cars. By trimming it as the fuel weight burns off, the driver can keep the wear on all four tyres as even as possible.

Are you assuming that this information is new to the F1 public? Especially this forum?

The adjustable wing is now in its second season.

Maybe if the drive was done via a cable and said cable was a bit, well, springy, such that as the car went faster, the extra aero loading would make the wing flatten slightly to reduce drag, and would come back into play as the car slowed heavily for the bends - but not using the drivers usage limited control...

Isn't that just like a flexi-wing? Which is not allowed?

[alexbarwell]

Weeelll, as with all these things, it is a matter of interpretation - it wouldn't be flexure within the wing element as such. Bit like the legality of DDD, or Mclaren's rear wing with gap. Don't know what official opinion would be.

6 degres .. more like, if any? ....

[gambler]

Love the stretch cable idea... but it would lead to an all or
nothing adjustment at high speed im afraid.

[marcush.]

would something like that not tend to oscillate? it would have to be something overcenter ...so it keeps stuck in the flat position when a certain force is overcome ....and only springs back when the force is considerably lower.. but then
how would you make it step up in braking areas ..

[gambler]

I think maybe the reason for the electric is the ease of changing
the wing out if damaged in a race.
but a mechanical adjuster doesnt use up any horse power(battery---alternator)

[DaveKillens]

Hydraulics are about impossible, the length of hose alone would add needless weight. Same with a mechanical device, and it would be prone to being inaccurate. That leaves electrics, which are very light, precise, and reliable.

With the manner of location on the steering wheel, the control is readable, accurate, and simple to operate.

what i fail to understand is ,just why they use a motor/geardrive assembly ..
you need power supply for the motor and some means of signal and feedback to allow for the position ..so either you need a pwm signal in and out or a highside input to make adjustments ..I assume this is not part of the engine ecu ,so you need recources on the chassis Ecu...
why not a small hydraulic installation ? one small actuating piston one mastercylinder and some sort of lever and a position feedback to know where you are..
that HAS to be lighter than a motor +gearbox wich is quickly adding 300 or more grammes and for sure this is more compact and better to integrate into the wing as well ...

Boy, whatever they use as the front wing adjuster, I really appreciate the technology they put into that tiny 6 degrees of adjustment in that very compact front wing endplate to operate! quite an amazing feat of engineering.....

so readily available ...not really F1 superdooper development there .put it into a lightweight case add milspec connectors and get going for 600€ starting point..
to shave of 200 grammes ..just add 20K€ development..

What I don't understand is, what do they do with it? When following in the wake of another car, do they give it a more aggressive angle by 6 degrees to counter the understeer? Or do they decrease it and just make it lift neutral so it's not buffeted by the wake?
