2.5 d does = L, remember d is the diameter, that is the top image max camber to the mirrored image max camber below.
and from the 0 point to tip of tail is 1.78d.
So if your vehicle is 48" high then d is 96"

Thank you. That sheds some light, but there are still questions.
How does 2.5d = L? They are markedly different lengths in the diagram. L is the overall length of the vehicle, and 2.5d is the overall length of the outermost airfoil shape.
What does the outermost airfoil shape represent? What does the other (smaller than the outermost airfoil, larger than the vehicle; not dimensioned) airfoil represent? Are they leading edge air buildup at higher and lower vehicle speeds, respectively? Which are therefore the vehicle's effective airfoils?
