Re: questions on multi-wing planforms



You might look up all the varieties of "Flying Fleas" and the Q-200 kits for
small, multiwing aircraft.

Firstly, I am new here although I've been reading for a few days. For
anyone with more knowledge than I, I keep considering building a small 4
wing aircraft. Not stacked, but two up front and two in the rear. I have
read frequently of problems supposedly resulting from interference of the
airflow between wings, but I can't seem to find anything very specific.
I'm fairly confident that interference between the front wings (or rear)
can be minimized by reasonable spacing and differing dihedral. I'm not
sure what the effect of the airflow coming off the front wings will have
on the rear set. I don't know whether I could remove most of the problem
by having one set considerably higher (how much?) than the other set or if
it is reasonable to have them on more or less the same height. The
reason for the concept is trying to get a wingspan small enough to fit
into a normal garage and conceivably take off and land from streets and
highways. I visualise something in a two place plane that would fall into
something of the appeal category of a motorcycle or small sports car. Any
thoughts would be appreciated.
