Will be ballance of the car effected by fuel load?

Post

I have read today that Rosberg said that he was running with aroud 150 kg of fuel and it has not effected car ballance compared to low fuel ride.
Does it mean that fuel is located near horizontal position of CoG of the car?.
Thanks.

That will be the target for the designer. Small differences will be dialled out by brake bias and front wing angle but generally the car must be balanced to avoid bigger over/under steer during the race.

Could they use segmented tanks or even dual tanks and pump out fuel in a balanced manner like planes and boats do? What are the rules about this?

that is pretty much what they do and have been doing since the 70's

Patrick Head has said that they consulted an oil tanker builder, consulted them to design the baffles.

That's right, F1 uses aerospace, and freight shipping technology.

Quite smart really to look there.

I think that even when you place your tank exactly on the center of gravity you will still expire some changes in balance when your car gets lighter.
When you dont have it exactly on it then your center of gravity itself can slightly migrate.

Empty car now weights 620kg. With 240kg of fuel on board it is ~860kg (few kg less or more). I see it as very difficult task to add 240kg in single tank and still have same center of mass once it is gone.. I`m not sure if F1 cars can have multiple fuel tanks like airplanes do..

Welcome.

One tank per car, with baffles.

No car will be using 240kg of fuel... 180kg max

If the tank is at the COG it should not be a problem for the longitudinal COG, though i want to know more details about moving the fuel about in the tank.
How is it done exactly, any documentation?
For Sure!!

pumps and baffles and 1 way flaps

plus they have a "foam sponge" to further help reduce splashing... or is it sploshing?

If they replaced the petrol with water they could put ladders on top and a rear brake man at the back and race the fastest fire engines ever.

One to ponder: as most braking and desired weight transfer would be towards the front at this time, but rearwards the rest, is the main body of the tank located forward of CoG with the more effective forward weight transfer when the car is heavier with fuel, as the car gets lighter that this transfer is less effective as braking is not quite so stressed?
