Constructing wind turbines on the field is a complex task. I thought about a design for a vertical wind turbine that is considerably easier to assemble on the field.
The tower of the wind turbine will be composed of threaded tubes. The tubes will be made of carbon fiber woven tubes filled with stainless steel instead of epoxy. Stainless steel is more resistant to wear and has lower expansion coefficient than epoxy. The tower made of intertwined tubes will be transported inside a full-sized container. The bottom section of the tube will be screwed with long stainless-steel screws to the ground. Cement can be used on the base as well. Then, the wind turbine blades will be attached to the inner most tube which has a higher height than the others. Then, the inner tube will be rotated using the attached blade sections. As the inner tube raises up to a certain height the locking pins will be engaged from the inner tube to the second inner tube. These pins will stop the rotation of the inner tubes and transfer the turning torque to the second inner tube. As the tubes ascent one after the other, more sections will be attached to the wind turbine blades. The second from the last tube will be actually the electric generator of the turbine. Therefore, it will be much thicker and heavier. The other end of the turbine blades will be attached to this tube. The last tube will be used to raise the generator from the ground to a safer height.
This design has a very low center of gravity compared to traditional wind turbines that are top heavy. Therefore, much taller towers can be constructed with this method. Most of the mechanical controls and electronics will be close to the ground level. Improving the tower’s serviceability. Additionally, the tower can be easily dismounted. This time, the tubes will be turned the opposite direction. As the tubes descent, they will disengage the locking pins and allow them to turn freely.
