my stupid power cord pulled out, while posting earlier, I hate typing so I'll just be brief...and I'll get back to the finer points later...

an you give a simple explanation of what wetted area is?
the amount of wing area immersed in effective [lift producing] flow at a given alpha
The pitching moment co-efficient, is that due to high pressure spots formed on parts of the fuselage monkeying around with the center of pressure?
almost changes in pressure distribution due to flow separation point shifting, at different values of mach
The skin friction drag I understand -- higher reynolds numbers would mean more turbulent flow (I'm guessing stronger shockwaves, more heat produced).
not necessarily, stronger shock waves just very complex shock wave interactions...most of temperature rise is due to compression of the air, although frictional heating term is important too
When you say the boundary layer slips? Do you mean that from the stagnation point the flow speeds back up at a slower rate than normal, and/or that the lower area of the flow accelerates up speed unusually slow compared to the upper layers?
it's more of a conceptual term, meaning the boundary layer fails to separate at points predicted assuming a constant 'flow rate'...by an amount 'eta' that eta is the coefficient of slip ---it really can't by theoretically computed---it's due to the long paths over which the air molecules must travel...
I drew this up. The sweep angles and stuff aren't absolute but the idea is that it has almost no sweep in the middle similar to a spatular section and progressively sweeps more and more as you go outboard. Ogival.
I can see how something like that would cut through and ride the waves---surfboard-like....and also a decent amount of area for the low speed regimes of takeoff and landing....I can't really say how it would do,...but you could probably get an airplane out of it---that's actually how it all really starts even the SR-71, Concorde, B757 etc...imagination
I'm sure that I'm being very simplistic overall, but as a rule of thumb I generally learn best by grasping the basic concept first and then proceeding from there.
me too...
