My question is about the maximum downforce of a typical formula one car. I know that the downforce varies between the different tracks it drives on, but there should be an average magnitude of the CL of the whole car.
I know that a rear wing produces ROUGHLY 30-35% of the overall downforce of a formula one racing car. Then i found in a german book about racing cars the following table, which shows the single lift/drag values for a formula one car:
where CW = CD and CA = CL.
So this book says that the overall created coefficient of drag CD is equal to approximately 0.934 and the overall created coefficient of lift CL is equal to approximately 2.802.
So far, so good. If i would now create a rear wing (an rough approximation), i could use the CL for the rear wing (Heckflügel) which gives me an value of CL = 0.899. That means my final rear wing should have this coefficient of lift, at best with the corresponding coefficient of drag of 0.297.
But now my big question which lets me doubt on the table above...
every text book which trades with wings (race car aerodynamics, competition car downforce, ali/wings...) have wing constructions which already produce (just the wing constructions) a CL of 2 or higher.
I designed now a own wing with 4 wing elements and end plates and it produces at the end a CL of 2.8.
If i compare this now with the table i have posted, this is much to high. Also the CD is, of course, much more higher. My CD is roughly 1.3.
Now my question: are my values realistic? or are the values in the table realistic?
why have the wings of all textbooks already lift coefficients higher than 2? ( multi wing elements) and the tables says something about 0.297?
I mean, my rear wing CL is higher than the CL of the whole car in the posted table. I'm now totally confused if my design is "realistic" or totally rubbish?!
I hope i can get some help with this issue ^^
thanks already
