Low down force and high downforce setup

Here are our CFD links and discussions about aerodynamics, suspension, driver safety and tyres. Please stick to F1 on this forum.

Low down force and high downforce setup

Post

guys ..i am kalyan and this is my first post here...i am doing my bachelors in aeronautical engineering...and i am an avid follower of f1 and its technological changes....

coming to the topic...i am planning to do a presenatation on the aerodynamics involved in the formula one wings...most of the info is done but i am left out with information regarding the setup of a car and wings for low downforce and high downforce circuits...i hope some one provides me with some info regarding this or atleast some externals links...thanks in advance

any chance you can put your presentation on here after you presented it ? I love to see what you have
Simon: Nils? You can close in now. Nils?
John McClane: [on the guard's phone] Attention! Attention! Nils is dead! I repeat, Nils is dead, ----head. So's his pal, and those four guys from the East German All-Stars, your boys at the bank? They're gonna be a little late.
Simon: [on the phone] John... in the back of the truck you're driving, there's $13 billon dollars worth in gold bullion. I wonder would a deal be out of the question?
John McClane: [on the phone] Yeah, I got a deal for you. Come out from that rock you're hiding under, and I'll drive this truck up your ass.

Well, welcome Kalyan, you can start reading the "similar" threads that appears beneath your thread and are a new feature from the last F1T upgrade :wink:

When you say info for the setup of the car and wings what do you mean? Angles? Force? Spring rates? Differences between rear and front? Dampers?

You could do a Goggle for sim race F1 car setup guides. We have a couple of threads
on the Forum.

Stop laughing; this is not such a a bad idea :D

hey thanks for the thing bellati ...when i mean setup i was refering to the wings and their angles that is basically the most aerodynamic parts.......and carlos i did the search and i dont think i found anything of my interest...

I doubt you'd find much. F1 team airfoil profiles are fairly nonstandard and heavily proprietary, as are setups. So I doubt you'd find anything on what AoA they're set up at.

Suffice to say there are some tracks with a high AoA and some with low :) Or different airfoil profiles. All I know is on a track like Monza you'd want that drag-limited top speed somewhere over 200mph!

Check out this page, there is a Java applet where you can play with a 2D Airfoils:
http://www.desktopaero.com/appliedaero/ ... iveaf.html

NOTE:
This program uses a combination of thin airfoil theory and conformal mapping to very quickly compute pressures on an airfoil. A method like this was used in the 1950's to compute airfoil pressure distributions before Java was invented. The section shape is very simple as well: upper and lower surfaces consist of a quadratic in sqrt(x) and a quadratic in (1-x), patched together at the control points. This provides just 4 degrees of freedom, but does lead to curves that look like airfoils.
With all those simplifications, the speed of F1 cars and aprox. airfoils dimentions you can speculate some maximun angles F1 teams can use before stalling

Ovbiously F1 wing profiles are optimized and interact with other areas (and dont forget its 3D) so you wont get exact values but you will be maybe 10% close for front wing and %30 for rear.... but thats just taking 10.000 assumptions :wink:
