This week I have more or less finished the design of the third generation of the glider. I have printed all of the parts and assembled the glider. A couple of notable design changes include the larger buoyancy engine (390ml vs 150ml), quicker buoyancy engine displacement change (~6 seconds vs ~30 seconds) and various cable management improvements (e.g. pogo pins to connect the electronics of the front/back and cable chains).
Whilst assembling, some of the parts required post processing, so I will work through the Onshape document updating all the parts with the minor changes and bar/wing mounts (I used second generation mounts as this was quicker). I also photographed the majority of the build so will be able to produce detailed build instructions.
A quick video demonstrating the newer glider is below:
This video is a relatively poor representation of the gliding capabilities of the glider currently as it is still changing pitch when it touches the bottom of the pond (if descending) and vice versa, so it could well reach an angle of attack which would cause it to stall, if the water were deeper. A deeper section of water is required to test the newer hardware more thoroughly.
