I wish their Paper had gone into greater detail to break out pressure drag and skin friction effects.
I'm not sure how to interpret the numbers.
The Dymaxion Car was previously estimated at Cd 0.25.And probably from top speed with the Ford V-8 flathead,compared to the Ford Model-A,with same engine and Cd 0.838 if I remember correctly.
The Model-A topped out around 80-mph.Something good has to be happening for Bucky's car to attain 120+.
If I were of means,I'd talk Harrah's Auto Museum in Reno,Nevada into parting with their Dymaxion Car long enough to trailer it east to Ogden,Utah for wind tunnel measurements in the new tunnel there.
It's a nice tribute to Fuller for them to go to the trouble to do the CFD.
Thanks for sharing!
