Drone drop testing the Hexagonal Annular Parachute


A while back I came across this "Peak of Flight" issue all about odd chutes or odd parachute designs (Direct PDF download here). In it featured a tutorial for making an interesting looking Hexagonal Annular parachute, Ages ago I made a quick prototype using string and tape and the canopy cut from a plastic bag and it made me interested enough in the design to sew a small one from rip-stop nylon.

I wanted to test the parachute but didn't want to move straight to chucking it into a rocket so I decided to build a drop test mechanism I could attach to my drone. Rather than reinvent the wheel the servo holding pin pushing part of the mechanism (see video) was 3D printed from some files found on thingiverse here.

 In the (badly edited!!)  video above I walk through the main components of the drop mechanism and then show some clips recorded from today's test flights and test drops. Massive thanks to my son H (9yrs) for his excellent help in operating the release mechanism.
