The experimental engineer in me got bored again and designed a single sail glider kite, with a swept forward wing. I just wanted to see if it could be done!
The design concept is roughly based on the outline of the XT-908 Drone in the pending 2014 version of Robocop, where I made some expected changes to allow it to be a glider kite.
Made the 24 in. wing span prototype out of PC-31, 0.04 in. carbon rods and 0.02 in. tip battens to test the design concept. Finished it last night and it actually fly’s and is very response.
The tips washout under load, which provides the desired tip stability. The following and the next two posts provide a few pictures of the prototype. Will spend time dialing in the design, and then make a second one using Cuben 0.33 and minimal reinforcements.
The material for the dual line version of my 48 in. wing span Rapere is cut out and I will build that kite over the holiday break. Also, I am making a lighter version of my 16 in. wing span Cuben Rapere. I just love how the Cuben Raperes (16 in. and 24 in. wing spans) fly.
