Plowboy Posted July 9, 2022 Share Posted July 9, 2022 I see no reason to test the aerodynamics of a model car. Quote Link to comment Share on other sites More sharing options...

It might be of some use to those of us who also race slot cars and need help getting body choice and mounting angle and position suitable for a specific track.

Or maybe, if somebody is interested in science and engineering, to get a visual idea of the difference in airflow over a barn-door design like a '32 Ford as opposed to a late model Lambo? Granted data developed in 1/24 - 1/25 scale doesn't translate to full size, but turbulence around chunky objects can be visualized and perhaps better understood. What I don't understand is the need to 3D print any of it. The side walls are flat, and cheap high-flow fans in their own housings are plentiful.

That is actually a valid idea. Eons ago at the dawn of time, I discovered that air can get under the bodywork of a slot car and lift it, making it leave the track...just exactly as years later I saw Mark Donohue fly the Can Am Porsche at Road Atlanta 1 Quote Link to comment Share on other sites More sharing options...

Brian Austin Posted July 10, 2022 Share Posted July 10, 2022 Wind tunnel testing has always involved the use of models, actually, only a bit larger. Quote Link to comment Share on other sites More sharing options...
