The wind turbine project was part of a University module called Sustainable Energy Design. Each group of students was tasked with designing a turbine capable of providing enough power to charge a smartphone. The turbine was required to be compact in its unassembled form, had to have a certain mounting geometry, and had a limited maximum sweep area.
I was in charge of designing and manufacturing all of the components (except for the generator) mainly using CAD and 3D printing.
The most interesting detail in the design is the bayonet coupling used to connect the blades to the nosecone of the turbine. A bayonet coupling consists of a cylindrical male insert with radial pins and a female receptor with matching L-shaped slots. A compressible spring locks and secures the pins of the male insert into the L-shaped slots. This assisted in the quick assembly and disassembly of the turbine.
