2017 Front and Rear Maximum Wing Dimensions

[sparrowf1]

Hi,
I am currently writing a paper on whether a modern day f1 could feasibly drive upside-down.

I have taken a look at the most recent 2017 F1 Technical Regulations although I am yet to find the answer to the following:
Front and Rear wing maximum dimensions? (Including number of aerofoils per wing and their dimensions)

Any help would be much appreciated.

Go to the FIA website - https://www.fia.com/regulation/category/110 click "technical regulations" and download #1 on the list for the 2018 rules. Then look at section 3.3 (pages 11-13) for the front wing and 3.6 (pages 23-28) for the rear wing rules.

The size of a wing is not indicative of it's force though - and most of an F1 car's downforce is from the floor. I would say a modern F1 car produces more in downforce than it weighs above about 160km/hr. A figure from a 2008 paper by Toet, Zhang and Zerihan is 3x the static weight at 250km/hr - but that's an old paper and the cars are almost 100kg heavier now than they were back then.

Do you have any more information that you can give on this? Like, is your paper going to try and do some sort of first order hand calcs, or potential flow or CFD analysis ofa rough model to see whether this is possible or not? Or are you merely just wanting a "number"of downforce to equate to the "number" of the vehicle's weight? What is it that you are after?

There is an article coming explaining how regulations form a 2017/2018 front wing, so stay tuned.

Sorry, should of been more informative. I'm doing the paper as an extended project alongside my A-levels as aerodynamics is an area I wish to persue in the future. As for the paper, in the current section I am working on I wish to equate downforce to the vechicles weight, using the equation from this paper: https://journals.le.ac.uk/ojs1/index.ph ... /1903/1804

I want to (if I can) replace the values for the maximum wing dimensions in the paper above with the most recent regulations from 2017.

Link doesn't work for me.

Equating downforce to weight is fairly simple though - the equation for lift is and obviously the weight is given by . Downforce for an F1 car will exceed it's weight, so all you're working out at which speed it does. So , at that speed the car will be neutrally buoyant so anything faster than that the car will be producing more in downforce (if upside down that's lift) than the weight pulling it down.

-5 to -5.5 for a current grand prix car, and mass (dry) is 734kg this year. International standard atmosphere figure for at 15 at sea level is 1.225.

As the wing must fit within a box defined by the regulations the size of a wing isn't proportional to its force, the camber and incidence, are more important. e.g. monaco and monza wings have the same planform area, but the monaco wing will produce high downforce and high drag, while the monza wing is the opposite.
