The air under the nose will be very limited next year, nothing compared to the last few years and also i dont think a smaller nose if you mean pointier will result in more airflow, a wider or normal as we have now but at that height is better.

IIRC, there is a minimum width dimension for the nose.

Which is what for 2014 compared to now ?

Yeah just like the Brawn car

Yes i do think too it will be like the Brawn but the Nose will be pointy like the MP4/22. That would look awesome.

I'm a big Fan of the low Noses.

No, they won't. Regulations require a certain area, so if it were pointy it would be like a bow.

15.4.3:

An impact absorbing structure must be fitted in front of the survival cell. This structure need
not be an integral part of the survival cell but must be solidly attached to it.
No part of this structure may lie more than 525mm above the reference plane.
It must have a single external cross section, in horizontal projection, of more than 9000mm² at
a point 50mm behind its forward-most point. Furthermore :
a) No part of this cross-section may lie more than 250mm or less than 135mm above the
reference plane.
b) The centre of area of this section must be no more than 185mm above the reference
plane and no less than 750mm forward of the front wheel centre line.

Edit: Already been posted.

This is what I have so far for the volumes allowed for bodywork for 2014 (not including anything else like the 75mm radius areas etc), for 3400mm wheelbase and where the front of the tub is in line with the FWCL (doesnt have to be, moving the front of the tub rearwards gives you a less severely sloped area for the nose cone).



There are some other interesting changes, like the fact that the curved edges of the floor have to have a constant curvature - That will surely have some effect on the area around the floor leading edge. Also by my interpretation the top of the tub can't be U-shaped (flat or convex only).

Still think that the nose cone will look like in 2009, before teams started following RB5 trend


I think section AA must be quiet high in the car below (more than 500 mm)
Not sure if cross sectional area at the 50 mm behind nose tip was defined

When you talk aout the Brawn, the 2001 Ferrari or the 2009 Williams, you mean just the nose cone, do you ? because I can't see how such noses/tubs can be legal under 2014 rules. unless the tub/cockpit is only 525mm high, not 625

When i say Brawn i just mean the noses will go down and be low like the Brawn, then how the actual nose to tub connection will look i cant say, perhaps it will be like ive mentioned before like the Toro Rosso and Red Bull of 09 that its like a steep hill down to the lowest point and low in the mid sections compared to the sides to meet minimum height, unless they removed or are removing that loophole aswell, which i think they did or will do.

Let's not forget that the RB5 nose was initially also an anteater design with a narrow tip. I'm interested to see how it plays out. I wonder if people will go for noses more similar to the BGP-001, or to the MP4-24

Nose tip centered at 185mm high
Front Bulkhead maximum height 525
Chassis height maximum 625mm

i think they will go for a really wide thin nose (a bit like the merc this year but centred around the 185 mark)

according to F1 engineers the 2014 Nose with look like this in profile and will look like an ugly thin banana protrudung from the chassis/bulkhead

Yeah maybe some teams will opt for a 2004 williams like nose + an inverted 'U' shaped section for the bulkhead (like the RB5 but upside down) so they get the nosecone as thin and the space under the nose as big as possible, if I understand the rules and the last posts well

With next years engines being bulkier and requiring extreme packaging I believe that through car aerodynamics will play a huge role next year. That even if you get your powertrain working well, the team who has the best through body aero will have the fastest car. The differences in wings and diffusers will be small, worth maybe a few tenths throughout the season's evolutions. The way you design your chassis, the shape of the crevices and tunnels, how air flows through them will be the most important aspect of chassis design.

Since about 2010 the powertrain guys have been working with the chassis guys because they were mixing the powertrain with the chassis(EBD, coanda ramps, tunnels). Now for 2014 the chassis guys and powertrain guys still work together but it's different in the sense that the power train isn't influencing chassis aero with exhausts but rather through packaging. Furthermore if a team was really clever I'm sure they could exploit the new systems to work as a sort of TC.

One last question: what do the regulations say regarding the turbine waste gate? Are external ones allowed? If so what is to stop a team from utilizing these exhaust gases in some way?

There is only one exhaust exit allowed. A turbine wastegate would I guess be converging into that one exit? I don't think they will be allowed to have a seperate exit for that.
