Filament wound airfoils. (again)

Howdy,

I was channel surfing the other day, and caught a glimpse of how they
make rotor blades for the Hind MI-8 helicopter on RT. (Russian News)
Very Interesting. They use small sections of metal (aluminum?)
honeycomb cut to the shape of the airfoil, align it them with the spar
on the leading and trailing edges, and then filament wind the whole
lot together, preesumably with carbon fiber.

I imagine a simmilar technique might be servicable for experimental
aircraft. paper fiber honeycomb is used as packing material and can
probably be had quite cheap. I was thinking, cut it to form, attach it
to the spar, drown the whole lot in epoxy. Then after it cures
filament wind it to make the skin.

Just a thought.
