Brother, aren't you in the industry?
There is virtually no problem with the Danish horizontal axis wind turbine, but the vertical axis is a concept that the Americans are currently demonstrating.
Pitch and yaw are fundamentally mature. The starting wind speed is not as high as you think. The number of blades is 3 and there is nothing that can be changed.
The foundation generally uses a ground anchor cage + concrete + pressure grout or other piles. How to make the honeycomb you are talking about?
Isn't the elastic device on the blade you're talking about Pitch? It has been widely used for a long time.
If you're talking about a small off-grid fan for your own home, pretend I didn't mention it.
Fan blades are integrally formed from materials such as fiberglass, reinforced plastic, resin and fiberglassrbone. They must be tested before leaving the factory to withstand various stresses. special vehicles (6 For transportation to the machine location (vehicle above the axis, with rear wheel steering), mountainous projects pay attention to the slope and turning radius of the road. When the road conditions are extremely limited, other traction equipment can be used for transportation
Transportation and installation of large-scale wind turbines in mountainous areas and offshore wind farms are currently also possible. important topics for practice and research.
