questions on multi-wing planforms
"ELIPPSE" wrote in message ups.com... pTooner wrote: 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. Gerry Hi, Gerry! Just remember this: if you take someone's word that something won't work, you've only learned to pass that off as fact in the future, and thus contribute to possible anti-knowledge and myths. However, if you read as much as you can about a subject, then try it yourself, even if it doesn't work, you'll know why. Go to www.mbda.net and click on one of the little symbols in the lower left to get "search", then put in Diamond back". A very interesting joined-wing, extendable-wing concept! Very interesting, thanks. Gerry |
