Glider Launched by Towline Method |
Through basic aerodynamics we know that in the Lift Equation velocity is squared. This means the lift is going to increase by a large amount with a fast throw causing a loop. Many people have put electric motors and radio control in these gliders but I thought maybe it could be launched as a "towline" glider with no control. Towline gliders are launched much like a kite flies but the line detaches at the top of a launch. I really went the quick and dirty route on this making the towhook from a paperclip glued to a craft stick.
Rails for Launching |
There almost needs to be another person holding the glider as it is launched except I came up with launching rails made from two dowels pushed in the ground. This worked pretty good and I could launch the plane by myself using kite string and a kite reel to pull it with. It never got real high for me but the glide was slow. This is the article I created about what I had done. Big Foam Towline Glider
Kite Reel Pulls Glider Up |
There is a short video segment of the glider flying in my video Fun With Foam Gliders.
