Ferrari 150° Italia

I would think they'd take a FRESH engine for quali and the race.

[King Six]

That's a high usage cycle. They're not planning on using that for Monza Q+R are they?

Of course not, just look at its usage pattern. It hasn't been used in a race since Monaco, only P1 and P2. The way the regulations are, you can use whatever engine you want up until the end of P2. Then for P3-Onwards you have to use the same engine or face a penalty. So that's why they use old/raced engines for P1 and P2, and then bust the crate open and use a new (or less used) one for P3-Onwards, but for Monza, it'll be a brand spanker.

[raymondu999]

Yes, but looking at Jon Noble's wording, it can get confusing. Also; they're locked into it since FP3? Didn't know that.

What is that thing between end plates in Ferrari front wing?

Interesting. Looks like an actuator of some sort?

From the Monza race thread:

[Richard]

It'll be a sensor, probably ride height.

[Holm86]

It'll be a sensor, probably ride height.

I dont believe it being a ride height sensor. It would give false readings when the wing is flexing. It could probably measure the flex of the wing.

Maby thats why we always see thin wires in broken RedBull front wings?

[raymondu999]

Actually how about a load sensor? Or a probe of some kind? I don't think it'll be there in normal running; it can't be good for aero.

[Lorenzo_Bandini]

[Richard]

It would give false readings when the wing is flexing.

Why false? They might want to know how close the wing gets to the ground as it flexes & wobbles.

Of course it could also be a pressure sensor for air flow in that channel.

[raymondu999]

Why false? They might want to know how close the wing gets to the ground as it flexes & wobbles

Because in that case it wouldn't be a "ride height" sensor. It would be a wing flex sensor; as Holm writes.

I can think of four ways to measure flex:

1 - Strain gauge - this would need to be at centreline of the car, not at the tip.

2 - Height detector - measures height above the ground but not the deflection of the wing relative to the car.

3 - Deflection detector - measures deflection between the sensor and another point on the car. This would be optical so needs line of sight. That wouldn't work hidden in that part of the wing. Incidentally it would be hard to work out the actual height of the wing to the ground with this.

4 - Accelerometer - this would infer the movement of the wing , but in an abstract way that is not relative to the car or the ground.

I think 2 is the only option if it is monitoring a flexing wing. Aero could be another option, but you normally see several pitot tubes feeding to a box.

[Owen.C93]

Yeah they can measure height from the bib area then work out what it should be at the wing. Then than can infer the amount of flex from that.
