In the early 1990s high nose designs appeared to formula 1.
Soon, most formula cars came to adopt high nose.
In this study, sevral typical nose designs during the early years of the high nose appearance were simulated to know its characteristics.

I got a request for “Mono Post Nose” like Footwork Arrows FA12 (1991), so I simulated it additionally.

Hello. I am working on an assignment called F1 in schools. I need to design a car so I’m researching different features. I am trying to find whether I should use a high or low nose cone. Your article is a bit confusing so I was wondering if you could dumb it down and maybe answer my problem. If you have any further information about F1 cars it would be much appreciated. Thanks!
Hi @yhyams !
Thank you for the reply!
Simpliy put, the final point of the summary is my conclusion.
- It is inferred that the amount of air flow in the area from the nose to the center of the front wing influences the amount of air flow below the floor.
However, whether the high nose or the low nose is optimal depends on the conditions such as vehicle regulations and the engine power.
And there is a further information of my article about an old F1 car - “F92AT - Double Floor”.
Regards,
Yosuke
