This paper airplane is my interperation of the Kline/Fogleman Airfoil. ?What's that? you ask. It is an airfoil design that incorporates a "step" into the wing, that seems to make a plane fly smoother and with less chance of stalling. It can be stepped on the top or the bottom of the wing. My design is on the bottom, and is adjustable as well, so you can decide how you want your paper airplane to fly.
A more complete history of the Airfoil can be found on this website, http://www.rexresearch.com/klinfogl/klinfogl.htm#ultim
and if that is not working, I have backed the site up here. http://www.theonlinepaperairplanemuseum.com/klinefogleman/KFBackUpHistory.doc
Enough technical talk though, it's time to build great flying paper airplane!
