Thanks all
That tells me some info I needed.
I do have damage to the wings and cowling that need repair, but it
sounds like I can do the repairs and get her flying again using the
standard techniques. Afterwards, using my idea, I will try some tests on
small prototype Glass-Foam-CF sandwich sections and see what the difference
is. If it's to my satisfaction, I'll do that with a set of new airfoils. The
old ones are RAF-48.
I'm still going to add the lifting attachments though, as my trailer
will have a boom which should allow me to easily and quickly attach the
wings without putting any undue stress on the wings. The time spent
attaching the wings has been a common complaint and I think I can improve on
that, as I don't intend to hanger her, but keep her in an enclosed, vented
trailer. The weight of the wings isn't the problem, the bulkiness is.
BTW..To clarify: the crosshatch of Vee grooves are lines at an approx.
60 degree angle to each other, extending from spar to spar, cut INTO and
bonded to the foam used for the skin form. I am STILL using the sandwich
construction Mark L uses. Each parallel groove is spaced 10-12 inches apart
(Think of the pattern between the spars, top of each X to Fwd spar,
bottom of each X to Aft spar, 10-12 inches between the center of each X).
The inside of the CF angle would then be filled with foam again, pretty much
impregnating the CF angle into the original foam form except for some
material which would used to bond it to the skin (think little flaps of CF
to each side of the groove). I don't expect the weight penalty to be
substantial.
I need to make a drawing. A picture speaks a thousand words. I'm not
good with CAD, but it looks like I'll be learning.
