No concerns of legality either.
The thread you started under was titled ‘legality’
I already had my version of the answer before I started the thread
That would have been great to see
For me on the crash structure ruling. It is tricky.
The crash structure rules are relatively straight forward, they do not demand open sections like the bodywork rules and give quite a lot of freedom aside from the tip positions and max height/widths. Red Bull can and obviously do, have a hole in the nose structure. As do most other teams, its just theirs is covered by bodywork which comes under separate rules.
For the Lotus, it seem you guys are not talking about the nose but actually talking about the turning vanes underneath the nose... Yeah. No great interest there because it is not really a hole in the nose, it more served as turning vanes under it. I don't think the function is the same though. And again this was doing with article 3.75. That lotus grille is not part of the crash structure.
The rules do not define a ‘nose’ rather separately define a crash structure and bodywork.
So Yes, we are talking about the Lotus nose, as the snow plough and legality vanes come under the bodywork one open section rules and thus are considered part of the nose bodywork. The horizontal snow plough vane created a hole in the nose bodywork, hence the reason it required the legality vanes. That is the same as Red Bull are doing with the resulting hole create in their nose bodywork by open crash structure
So Force India nostrils and Lotus turning vanes. Not part of the crash structure. Just hanging off it. Clear as day.
Exactly as we have described, there are two rules defining the nose, the crash structure and bodywork.
RedBull hole in the nose? Is it a part of the crash structure? You say yes... And maybe I might believe you... But we do not know how the exit of the hole looks.
The hole or rather the carbon structure formed around it, is part of the structure, as it’s in exactly the defined in the X and Z axis and appears the correct 9,000mm2 cross section as defined in the crash structure rules. If it wasn’t the red bull nose wouldn’t be legal, with or with out the hole. There can be no arguing about.
The exit hole has yet to be seen, but is also defined by the structure rules, just as with the front hole. So its detail is irrelevant as its legally the same the front hoke.
I will break it down with these illustrations
The nose is formed of a crash structure with relatively free rules in terms of shape or holes, to this bodywork is added, but this is not subject to the structural rules. The legality fins are not part of the nose structure, but bodywork.
Once the crash structure is defined its shape is made up of the visible structure and added-on . This must meet the single section rule.
Red Bull use bodywork fins staggered inside the nose hole such that adjacent edges line up, this allows airflow and still provides a solid face to meet the rules
When sections of the nose bodywork are taken a fin will always been part of the cross section keeping the bottom of the nose hole joined to the main cross section.
