This wind turbine has no blades Can it be rotated? According to the Magnus effect, a cylindrical rotor rotating in the wind will generate lift When the rotation direction of the rotor on the windward side is opposite to the rotation direction of the leeward side, a torque in the same direction can be generated to make the wind turbine rotate. The theory is so, but in practice ? How fast can it be ? Only through experimentation can we know. start testing, Incorrect rotation of the rotor so that it is not aligned with the wind direction, Modify the phase angle parameter and try again. The phase is correct this time, Windward and leeward sides rotate in opposite directions. It turns quite smoothly, This makes it clearer How fast can it rotate ? capture data to display The rotation speed of the rotor is increased, and the speed of the wind turbine is also increased. The wind speed is 3.5 meters per second, continue to increase the speed, Over 100 RPM seems easy, Then increase the wind speed, the rotation speed of the wind turbine is also increased. over 120 RPM, Wow, the strips are flying off ! The wind speed is 4 meters per second Reduce the rotation speed of the rotor, the speed of the wind turbine also slows down, The speed is controllable. Then test the acceleration. It can go from standstill to top speed very quickly. According to this experiment, the Magnus effect can also drive vertical axis wind turbines, This wind turbine starts quickly and its speed is controllable, To align the wind direction just adjust the phase of the rotor speed. Is it very potential?
