Hi. Avian here.
I am developing a mix between an airplane and a sailboat. (Yeah Kind of like in Peter Pan or The Mummy (Scorpion King episode). The difference is of course that this is a serious approach to an actual flying sailboat.
There are working examples out there of Ground Effect Vehicles, that power of a motorcycle gas engine. However None of them are powered by the wind. In order to make things a bit smoother I will work with micro-controllers, electronic sensors and alternative servo actuators to manipulate the partly home brewed control surfaces that hopefully will keep this thing floating through the air in an intended direction.
The one example in real life we have that a perpetually flying oceanic ship would possibly be able to maintain flight is a big and famous bird:
The Albatross consumes zero energy in flight. I hope I will not have to mimic the physics of this bird too much. I have and will be working in Blender 3D to mind-map all the details necessary for success. The Umbrella term I have chosen for my project is Ocean Homie. The 3D model above goes by the name Air-Ploat One.
