SEE?

[marcush.]

so lets see how much they deviate from what we have seen up to know in australia..
a new nosecone ? probaly not if they have not strted this a while ago and could align for a crashtest..is this a test with tub?
but then again the issue seems mechanical .(understeer on the whole range of speeds )
the wing cure should help the quick er corners but also kill their speed on straights...efficiency is not grown on trees as we have learned.

A wheelbase change, perhaps? I presume they'd have to make it longer in order to shift weight off the front. Would there be room on the tub to do that?

I think this would be the quickest way of soting the issue.

I remember at launch a number of sites mentioning how "short" the wheelbase was.
Seems an avenue they could be exploring.

[autogyro]

I still think the problem stems from ride height control and to hard a spring rate.

i mentioned this a few posts back as it seems unlikely they could find a lot of weight in the front end to remove...so the trick would be of course to move the front whhels froward....so new upper and lower wishbones aimed more forward ,maybe even moving the steering rack a bit to the front,but also a need to reposition the front wing accordingly.plus possible new pushrod modified rockers/or rocker positioning....quite a different car in the front then..
the low nose could be moving if not modified into a unfavourable position with this effectively causing a bit of converging flows between nose and tyre?so new crashtest.
so this maybe a solution but a very elaborate one with lots of new parts and molds to be made ...

Thanks for the link. So then, if you are struggling with weight distribution too forward biased, and with a nose that gargamel would be proud of. Would you not redesign the nose?

Front wing is a temp fix. Total rethink required

They said they couldn't find any weight to move back, not our nose has too much drag.The nosecone is not their problem or they would've said "our nosecone sucks",instead they said "our weight distribution sucks"

[Morteza]

I think the understeer problem comes from the less grip the front tires making, and they haven't found the solution to correct it. It has sth to do with the weight distribution or suspension I guess not the nose.

This idea comes from someone who's just a fan not a technician, so don't take it too hard on me

I agree, this solution is not an insignificant amount of work, and may have a serious impact on their nose cone design. I think it depends on how sensitive the "kink" on the underside of the nose is to the position of the front wing and the wheels. It would seem impossible to bring the kink forward as it looks like this is designed into the chassis rather than the nose.

hence the big timeframe they already communicated to rectify the root course.

Do you not see that the nose of the car is in fact the issue here?
Mercedes have too much weight ahead the driver, they cannot remedy this quickly. So probably not Aero but definatley weight distribution issues going on that Marcush has already point to with the RTL news story today.

So where do you propose they shed the weight my friend? REDESIGN THE NOSE!

A PERFECT example what race engineering is all about .
1)have good communication skills
2)understand the problem
3)come up with a sound technical solution and be prepared to present the solution
to the people who actually have to believe in your abiluity to solve the matter
4)get the solution put into reality as intended
5)check if all is done according to plan
6)reality check

we are stuck in communication issues here ,and talk paralell world s as we do not use a common terminology.
A nose is not a nosecone at least for JohnsonEvilTwin,and me two ..you could of course also call it front end ,front or whatever ,as long as we all agree what it is we are talking about.

to me we agree in reality but we still argue.. and the free practise session may be over already and we are loosing precious time to prepare for FP2...

brings up the difficulty the boys will face in Australia..actually knowing the car is not going to work ,is crap in their minds and still try to figure out a solution to get the best out of the weekend...It is very intriguing to talk the car down but very demoralising as well .Still I believe guys like Jock Clear are like a rock in the sea at those times...are they?

[JohnsonEvilTwin]

Does Jock Clear have engineering influence at Mercedes?

Also can you knowingly shut down a cylinder in a modern F1 car?

he is Nicos race engineer so he has final say on setup and strategy I´d think?
