Building Model Airplanes That Fly
Designing paper airplanes with wing camber?
I made one of these for the first time, and it flies much better than the design it originated from (a high wingsweep, no camber design). I don’t have a camera to take a picture of it though, so I apologize for that. Other design features include upturned winglets, anhedral, and vortex generators positioned perpendicular to the leading edge. So far, it’s capable of flying a large rubber eraser. I nearly ruined the prototype this way so I’m building a second model. Has anyone else designed paper airplanes with wing camber? I would be interested to hear any ideas.
I have experimented with camber by simply putting a thumbnail crease along the bottom of the wing, just aft and parallel to the leading edge. It seems to have a beneficial effect on some designs and not others.
The Paperang (http://www.paperang.com/indy.htm) employs a small amount of variable camber in its design. In general, more than a very small amount creates too much drag in small thin wings that operate at very low Reynolds Numbers. Read this: http://www.paperplane.org/paero.htm Scroll halfway down the page (or use Control F) to find a brief discussion of “camber” in paper airplane wings by the world record distance holder.
