Why don't vehicles have aerofoils to partially take the weight of the car?

But I think you meant www.tesla.com/sites/default/files/blog_attachments/the-slipperiest-car-on-the-road.pdf

That's it! Thanks.

No, thank you. It led me to the history of testing article.

Anyhow, I don't think anyone has actually attempted to make a vehicle that specifically has air foils designed to create partial lift for the purpose of reducing rolling resistance.

All three of my most recent posts show SAE papers that demonstrate the concept of air foils designed to create partial lift for the purpose of reducing rolling resistance.

Maybe try talking to the wall???

Thanks! I just got done reading your last reference. I must admit I had skimmed over a lot of thread.

Made me look.

Englar and Georgia Tech were discussed here times past. Here's a color version of picture that appears in the PDF, dated to 2013.



Eight years? Time flies whether your having fun or not.

I don't think that the idea you could drop rolling resistance by using aero lift was ever in question?

The issues were about control, the potential for increased aero drag through doing that, and the practicality of doing it on road cars (because, after all, that's what we modify here).

Interesting. You can't do that in the US or Australia - according to the official info.

Your above assumption on thoughts that you can't understand, that they where only considered for less than a few seconds before sharing, is a good example of both in my world, especially now that you have tried to go beyond even doubling down in your attempt to wiggle out of your original blanket narrow statement on "ideas".

The hole here is getting deeper.

You are the one I am tempted to laugh at.

Look, you wrote something that is pretty silly:

A moment of thought shows that anyone who does this is going to spend their life embracing an infinite amount of rubbish.

Most people let your sort of comment pass (just like they do with: "there are no stupid questions") but if people keep spouting garbage and no one challenges, then it just goes on and on.

I showed the silliness of that notion very easily with my moon/cheese example. If you can't see that, that's fine: keep voraciously chasing mirages. But for me, and most people I professionally deal with, that would be a waste of a seriously finite life.

Instead it is far better to say, "When confronted with a new idea, I ask for the evidence for that idea, and then weigh that evidence up carefully".

[Shrug] I can see lots of stuff here that has taken on a life of its own over the years (eg The Template), where there was a severe lack of evidence but it was adopted wholeheartedly* - so maybe what you say is of no surprise.

*Yes Freebeard, I know you occasionally demurred.

I just see so much rubbish circulated re car aerodynamics that one starts to wonder what intellectual rigor (propositions; evidence for those) people are actually applying. Usually, very little or none, I think.

This discussion isn't limited to cars though, and neither is this forum.

Control, turn off the aerofoil, solved.

Works on a car, read the referenced paper.
No or positive impact on stability, read the referenced paper.
