L/D

Supersonic L/D is very complex, as angle of attack affects drag
drastically. You would almost need a complete set of aerodynamic tables
which show normal force and axial force coefficients as a function of
both Mach no. and alpha. I am sorry, but there is really no simple
answer.

I realize there is no simple answer, I was trying to elude to that point when I
first asked the question. Of course alpha effects drag which effects L/D, and
on, and on, we go. I am not asking for a detailed engineering exercise. All I
am really asking "is there any L/D published data that may be found". This is
a very, very, very top level analysis, not a detailed engineering exercise.
You might say extremely parametric is nature. All configurations have an
optimum L/D (max) for given mach point (taking into account everything you
describe and more), and that is what one usually finds in the publications.
Everybody shows there best.

I do appreciate your response, but all I am looking for is something ( that is
somewhat reasonable) to turn into a point on a chart - LOL.

Thanks again
