Title: This is aerofoil, winger, or what? Post by: yashb on April 15, 2011, 01:14:12 AM Dear Friends,
I with help of one of my friend, and some research build this. This is aerofoil, winger, or what? Please Suggest. And of-course this can fly. Try to post video tomorrow. here are some pics for you.

Post by: abhay on April 15, 2011, 03:37:08 AM 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.

Post by: rcpilotacro on April 15, 2011, 05:41:09 AM 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.

He would not have started reading proper Algebra / Physics at School Yet!! Title: Re: This is aerofoil, winger, or what? Post by: Vector on April 15, 2011, 01:21:03 PM nice eg. here,
Title: Re: This is aerofoil, winger, or what? Post by: rcpilotacro on April 15, 2011, 02:32:32 PM problem is too much of directional stability, and very reluctant to turn apart from other design issues

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. Title: Re: This is aerofoil, winger, or what?
