Savonius & Gorlov VAWT

thingiverse

This vertical axial wind turbine is designed for domestic wind harvesting, but can be scaled to any application. It features a NACA 0015 profile and a self-starting Savonius component. The Savonius size ensures optimal speed when the Gorlov turbine reaches its peak efficiency, preventing unnecessary drag. To assemble, print a top, base, and at least two atomic sections. At present, there are no dovetail connections, so be cautious during assembly. The turbine is designed to fit onto an 8mm threaded rod. Assemble, glue from the bottom up, leaving the top section free for captive nut insertion. Use printing filament of your choice through blade holes, currently configured for 3mm but adjustable in the SCAD file. For easier assembly and balance, print three atomic sections with support wings. Almost every aspect of this turbine is parametric, allowing camber experimentation. A recent study suggests a camber of 2 may aid self-starting without a Savonius but reduce maximum torque harvested. Updates include improved structure for easier assembly and strength, plans for an integrated base and printable generator in the future. Check back for updates as this design continues to evolve!
