I've added 5 more pages of tables for Cd comparisons.
The data was presented by General Motors researchers in 1962 in the SAE Paper identified and I've put it in pictorial form based on their tabular descriptions.
The second image on page-1 reflects photograph from tuft-testing for the chamfered-nose trailer van which I imposed upon the line drawing of the semi-trailer.
The data reflect Cd values as they are impacted by tractor or trailer leading edge radii,or lack thereof,and the effect of tractor height and gaps.
Again,I'm putting them on page-25 at permalink#248.
