Savonius wind turbine

prusaprinters

<p>Based on different scientific papers I created this <a href="https://en.wikipedia.org/wiki/Savonius_wind_turbine">Savonius two blade shape wind turbine</a> design. It is specifically designed to work well with low wind speeds coming from one direction.</p> <p>The turbine needs a obstacle wall in front of the blade that comes back in order to increase momentum. I created a case for this turbine with obstacle and deflector walls as well as a wind tunnel. I will link to the files as soon as I have tested them.</p> <p>Notes:</p> <ul> <li>The blades are higher on the ends to compensate for the bending when fastening the brass nuts. Maybe some additional grind is required to get a perfect fit without unwanted blade bending.</li> </ul> <p>Additional materials for this design:</p> <ul> <li>1 x T8 lead screw</li> <li>2 x brass nuts</li> <li>8 x M3 screws</li> </ul> <p>Edit:</p> <ul> <li>The design is to heavy for a light breeze. You need to reduce the fly wheel weight (bottom &amp; top plate thickness) and also reduce the blade thickness - additionally you could print it with foam filament.</li> </ul>
