Even i have made a glider like this. I dont know whether to call it airfoil, but its sufficient to resist wind, if in motion.

I read it in some book. The brown stick is a broom stick, and the rings are made pf paper, joined with cellotape.
the glider glides like in picture "c", the smaller ring in front, and stick downward.

Practice, and only Practice will make you perfect



There is some thing called Circulation Theory of lift and Ideal Body of Revolution, this contraption is normally used to illustrate that concept in an Aerodynamics class, yeah, flies well , theoretically has no Lift Induced Drag.

problem is too much of directional stability, and very reluctant to turn apart from other design issues

dear yashb,
                you can make a prototype by adding a thrust source to the leading ring(to the glider shown). and the battery and Rx on the trailing. This is how i wanted to build one.
A single ring, like seen in the live example would not be under control without gyros i think.
