Monaco aero setups in F1.įor your purposes, I wouldn't bother getting too in-depth with the analysis.
In some cases, reducing the drag at the expense of downforce can decrease lap times. In other words, they are inter-related and should be treated as such. A robust analysis of the combination of vehicle dynamics and aerodynamics, with respect to race car performance, requires a systematic approach. The problem with answering the big picture question you're asking is that there isn't necessarily a correct answer. They were developed for a specific wing setup, and don't necessarily translate to a different configuration. Slimjim8201 posted these on twin element wing that was originally published in racecar engineering, in the 'Reducing the drag of a two element wing through stall' thread: I'm very mindful of balance, and am this all about fun. If the wing tightens the car up too much I'll either shorten the rear sway bar arm length or add a front air dam/splitter.
I'm already pretty loose, but don't want to pull the rear sway bar. Many guys in my class with similar set ups are already pulling their rear sway bars completely. However, if you just do this as a casual hobby and you want to build the wing for fun, then have at it. Not to say you're wrong to add a wing, but it should be considered if the goal is to decrease lap times. Mystery Steve wrote:You're limiting your chord length to 5.5 ft? Do you mean span?Īlso, I assume you are just adding a rear wing? If so, you want to be careful with the mindset of "adding as much downforce as possible." While downforce does help with traction and cornering ability, you need to be mindful of the balance between the front and the rear. I've seen so many great technical discussion on this forum, and I reall don't know where else to turn. The car is a bit overpowered, so drag is not really a concern, just as big of a -cL as I can get get within the above constraints. I'm really hoping that somebody will just give me a solid airfoil reccomendation that will fit 's requirements, so that I can build it. I'm a medical doctor, though and not an engineer. I've been searching for help in selecting a pair of profiles for my two element wing. We can cut any airfoil that has been designed or modified in Compufoil, Profili, or stored in Compufoil (.cor) file format." We also can generate NACA 4, 5, and 6 digit airfoils. We have several hundred airfoil profiles to choose from. I found a company in Texas that will cut custom foam cores for the wings for a very modest fee. total means that the combined width of the two air foils should be below 17.5". For other classes I should limit my span length to 5.5 ft.
And am interested in building my own rear ring for my SCCA Super Street Modified 300hp mazda miata autocross car. I have a long history of wing construction with r/c gliders, have read "Race Car Aerodynamics: Designing for Speed" by Joseph Katz cover to cover 3 times at least. I've recently started autocross racing where my car rarely encounters speeds over 80 mph.
