high lift airfoil data for race car downforce/ground effects
high lift airfoil data for race car downforce/ground effects
(OP)
I'm 'designing' a race car that will have what is essentially a large inverted wing section as the body,to get max downforce ( with the leading edge between the front wheels and the trailing edge between the rears.) The top and bottom surfaces will have clean air- flow. The chord will be approx 2700mm ( 9 feet ), the span will be approx 1100mm ( 43") & the thickness approx 500 to 600mm ( 20-24").The 'wing' may include front leading wing slat & rear will have a seperate adjustable flap, as well as full side fences. The "working" speed range - between 50 to 120mph, drag will not be a concern,
Questions; =suggestions for airfoil profile data,soft-ware etc for a wing with such a low AR. 'lift' figure calc.
=how to calc centre of lift for front to rear balance of car - will rear 2nd flap alter this much?
=As this wing/body is operating close to the ground it will operate more like venturi tunnel setup and so what other complications / modifications to consider.
I'm a novice in the aeronautical field so any help in simple terms is greatly appreciated.

RE: high lift airfoil data for race car downforce/ground effects
Most effective wings are mounted above the car - Outlaw sprint cars, indy/FI rear wings, etc. to eliminate trying to package the drivetrain within the confines of a proper wing shape and keep the lower surface in clean air. If you have no rules, concentrate on making the tires aerodynamic, since that's your major air dam in an open wheel car.
There are a number of sites that have aero programs, so do a search for WING PROFILE or Aerodynamic Calculators. Martindales Ref Desk has a couple good links.
Good luck.

Any hints / data from any-one on ground effects in relation to this concept? many thanks for any help.
