I've dropped this into two threads already, oh well:
1993 Dymaxion Concept Car Aerodynamic Analysis

Figure 2 is a ‘drag accumulation’ plot which shows hows the drag builds up along the length of the vehicle. It’s is interesting to note that the total drag of the car up to the front wheels is almost zero for the straight ahead flow and negative for the 15 deg yaw case. In other words, a significant amount of thrust is being generated around the front of the car which offsets the stagnation pressure acting on the nose.

This Yawing coefficient must be what causes the Dymaxion to yaw into the wind instead of being pushed sideways.

*You want to pull the body in as freebeard does with his redwood bender-board.I've been using 1" Schedule-40 PVC pipe as a 'french-curve' held over bulkhead station points which define major body vectors.The redwood or pipe will perform the calculus for you,plotting a smooth curve profile for fabrication.

I'm going to sort my redwood (up to 16' lengths) into clear and knotted.
