Vertical Turbine - Derived
by julienM, published
A derivative, maintaining the assembly procedure, but hopefully improving the aerodynamics.
Includes a drop-in replacement, in which the wing profile is swept to make a smoother surface.
The other part is much larger and based on a NACA 2818 profile, which should apparently improve power. The arms are a much narrower oval shape to reduce drag.
The NACA2818 profile includes holes for extra stability. Either a long wire can be passed the entire length of one blade, or short dowels can ensure a good fit. The rear edge should obviously be much sharper, but this was creating prints with a disconnected rear edge.
The pegs visible in the photo were meant to allow interlocking between layers. This would require two sets of parts, as there is a 30Â° "shift" after every 3 parts. The holes for the dowels should serve the purpose sufficiently.
I may design the top and bottom parts that would be required for a proper turbine, but I want to investigate the profile in OpenFoam first. That may take a while, or never happen. If someone needs these parts, just say so and I will just make them with the current design.
EDIT: Top and bottom parts added. The .zip includes 5 extra pieces that need to be printed to have the top and bottom blades in a plane. I would suggest making a round plate for the top and the bottom.<
