The same drag as one very ineffecient wing, that is. So as L/D 0, it
starts to not matter as much whether you've got a monoplane or a
venetian blind.

And please, nobody ask how you make a venetian blind. I do remember
when 16Kb was the size of a gym locker. BTDT, still got some of the
core beads.

On a slightly different topic: Jay, when I was pointing you towards
joined-wing concepts in the earlier thread and also in private email,
I really wasn't trying to be snarky. I was trying to point out a
configuration that:

* Suggests a practical application for something like a biplane
configuration

* Has been studied enough to suggest that it offers, in theory at
least, some advantages over other configurations

* Is not well explored in physical hardware (NASA canceled their
proof-of-concept aircraft and put the AD-1 it was based on in the
Hiller museum)

* Would look relatively cool and unusual

Thanks, and best regards to all
