How Do Canards/Dive Planes Work? 

Kyle how widespread is the use of topology optimization methods in motrsport? I always see these incredibly organic shapes and can't help but ask myself who came up with them. And since open source software like SU2 has support for adjoint based topology optimization, I was wondering if there is any use to applying this to a race car. I know that in the solar car arena it is often used to decrease drag. Anyways, I just wanted to pick your brain a bit, thanks.

@@acruzp there are lots of parts that can be subjected to topology optimization.. The whole car itself with the rules as constraints. Regards!!

So you decided to remove all the CFD videos? WTF Kyle. Is it really that the paid content is then the exact same. Sadly these videos would have been helpful to tons of people for years to come, now they are all gone.

$100 just bought me a 4x8 sheet of Alumalite. A few dollars more for some generic mounting hardware and you could make a splitter & diffuser that's lighter and stronger than all but the most expensive dry carbon fiber pieces.

Get canards ;P xD

Take off your stone repeller on the front of your hood., And keep your windows up when driving over 100km/h

oh hello haha

Does this video do it for you, or do you want something more specific? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cDKBYfslzSw.html

That video explains vents on the top of fenders quite well. But I'm wondering more about fender vents located behind the front wheel. Like the kind you see a lot on FD RX7s.

Hello michael haha

Old comment, you probably have your answer by now but its almost in the name. A splitter divides the air, forcing most of it to the upper surface to both direct it to the radiator and to create a higher pressure zone above. Also by limiting the air going below the car, reducing the lift turbulent air underneath causes. Some splitters have a curved under surface on high end race cars but are often also just a flat plate that works well with a flat underbody to help the goal of getting the air out from under the car quickly. You can see on a wing however the whole body of the wing is in the airstream. Look at an F1 car. the job of the front wing is not to divide the air, but to interact with it as it flows over the wing, causing pressure differential in that manner.

He made videos on that subject....It basically comes down to "HOW EXTREME" your aero is. He said a WRX STI wing doesn't really do anything below 120 mph. By Comparison a One:One or ACR Viper will produce downforce that you can feel at 60mph or so. Downforce/Drag goes up 4 times as speed doubles. Most cars it's only effective at 150mph+.

The "two layers" would have to be very far away from each other.

@@yayayayya4731 Would it be okay if the top layer was about the same height as the roof line then?

@@nickamarit then it would be a wing then 😅, except mounted on the bonnet,

@@yayayayya4731 Ugly but probably functional though.

@@nickamarit the huge Chord of the wing would be pretty useless though🤔

It's How far Forward...that makes them effective. An ACR Viper drive said that he "Most definitely felt a change" when he lost one in a Race.

dam i belive

It's not really either, it's more of a modified bumper shape that's between a canard and an extended splitter. "Air dam" isn't a great term for describing bodywork as it's very vague.

maaz it's producing a high pressure region above the lip..sucking the nose down and extracting low pressure bullshit
