Interesting,
I am finally starting to get a handle on what the numbers you quote mean, can be a bit slow at times.
With the Tuna, it was near enough to template, 2.5:1, on side profile, but on plan view is at ideal wing cross section, 4:1.
I was thinking how can we take something from this, which one of these is the governing measure, or are they the outer limits that natural selection has shown to achieve the most efficient movement through water (or any fluid).
With the wing section I assume this means in wing form, that it theoretically can continue this to infinity at 4:1 as the minimum drag form, where as with the body of rotation is at 2.5:1.
So with motor vehicles in ground effect (mirror) we have some elements of both of these characteristics, it is like a body of rotation, but has flatened sides, top, bottom etc, which give it some wing character.
Do we need to consider our vehicles in this manner and take some elements from each profile to best address the aerodynamic drag?
Don't know what or how, just playing with ideas.
