Dr Kamm studied this extensively and concluded that if it wasn't
possible to carry the streamlined body shape all the way to a point then
it was better to chop off the tail. I suppose he had some conclusions as
to where that tradeoff occurred but I don't have a copy of his paper so
I don't know any details; it was probably in German anyway.

Subject: RE: Sreamliner question.
Exactly, Mayf. If you use a curve with a radius that has a <7 degree
tangent to the LOCAL airstream, the airstream should stay "attached."
You're right too about trying to minimize "wetted area" to reduce
surface
drag.

Now folks, why do you assume you can have only a one time 7 degree
taper?
You can multiple ones. In fact you can have so many that it becomes a
smooth
curve. So all is well...
mayf, out in Pahrump, where it is finally warming up a bit...
