here is a quick and dirty mock of my ducted wing design. The idea is to create the wing from rapid prototyped poly carbonate with a carbon fibre spar bonded to it. The duct is built into the design and feeds air over the wing from a ducted fan. The RP machine builds wall sections to 1-0.5mm and can create a structure with complicated ribs and internal structures in one go.
what do you think of the concept?
Any idea of where I can find a good aerofoil shape suitable for a low speed UAV?
