Random Wind Tunnel and Smoke Pictures Thread

I have noticed those slots in the end plates and wondered what they do.



Oh, OK. The red arrow gets bigger for the same reason the VW Beetle and GM EV-1 have good airflow down the backlight—only upside down. And backward. Hmm.

Aerodynamic streamlining was the craze in the 1930s. Now it could become the paradigm by which we design future motor vehicles

Anyway, the way the shape was achieved was steel plate cutouts were made matching the windshield and radiator shape and areas.

A blower or wind machine of some kind placed in front, and clump fulls of sand were tosses into the airflow. The sand would hit the steel plates and deflect/move around the plates/objects. The pattern of this sand migration/movement was recorded somehow and replicated to form the aluminum body.

If or when I ever find my pictures, I'll post them. This same car was on Hemming's or some other site within the last 9 months as a feature.

Found the business card.



freebeard, now you can find all sorts of images and articles on this "aero-sand car".

It was here last year, and Phil (Aerohead) got to see it. A Cd of 0.14 is impressive! The floor (between the wheels) rises up.

I got all excited when I first saw it, then discovered my timing to see the car was, a "Little Off". Phooey (:-(((

Looks like back in 2009 they were thinking that a street adaptation of this concept would be a 3-seater.

The rear looks way too high in that rendering.

The 2009 version.

I'm pretty sure that the later version has a lower tail.

Apparently there is more than one. This one is a little more street-roddy.
