Supermodified Racecar Wing design
Просмотров 9 тыс.11 лет назад
Quick tutorial on designing a highly efficient race car wing for maximum downforce. In this case, we'll design a Supermodified wing using Java Foil
These wing designs probably don't take into account stall. A supermodified can stall out just like a plane. In my opinion, those angles of attack are too steep to be functional. You're just using the air hitting the wing to produce downforce, not Bernoulli's principle. Never understood race car wing designers.
Your camber is upside down. The straight part of the wing should be on top. You're not trying to fly the super, but pin it to the ground.
He's measuring lift, but when you flip it upside down you can expect the opposite. The pic of the car shows you he flipped it the right way. That part is pretty obvious.
@@mattbyrne4987 You would think he would mention it. Not everyone understands Bernoulli's Principle.
@@JohnnieWalkerDread Haha, I get it, but I'm sure the folks watching this vid have a good idea. I think most would just scroll on by. They would be like WTF is this? This isn't a cat video...
@@mattbyrne4987 True. True. I'm perplexed by his claim that the real downforce would only be 80% of that calculated by the simulation Why?
@@JohnnieWalkerDread I'm assuming because simulations are a "perfect world scenario". They are never 100% accurate because of the uncontrollable environmental factors of racing around other cars and weather. Just a guide to get you in the ballpark.
I see new wings on the supers this year. Are they better? Are the simply a new requirement? Did someone experiment with it and prove it to be a better idea, so now everyone has them?
Thnk you for your service kid
how did you know to multiply Cl by 0.8 and Cd by 1.2 for the 3D effect . do you have any source that can support it?

Jim I RUN A MODIFIED CAR SE USA AUTOCROSS . THE CAR AT THIS TIME DOES NOT HAVE A WING. I WOULD LIKE TO BUILD A WING FOR THE CAR.I WOULD LIKE TO GET SOME ADDITIONAL INFO FROM YOU ABOUT THE # 94 CAR WING. HERE IS MY E-MAIL ADDRESS FOXE@ COMCAST.NET--------------------ALSO CK. MY VIDEO BD5 AIRCRAFT IN MIAMI---THANKS , RON
Great Stuff! I will try it and compare it to the calculations that I did on Jimmy McCune's Supermodified last year. Can you please continue and show how the wings effect down force on each wheel. Looking forward to your next installment.
i like that car, just happens thats the car i used as my display picture on youtube, i took the picture at oswego last year, had to squish it together a bit to make it fit the requirements, nice video on the wing design,
Thanks for the video Jim!
