Question: What should I do if I find that the windmill on the mountain has broken wings?
Answer: If I find that the windmill on the mountain has broken wings , it needs to be repaired. Since the large windmill on the mountain is used for wind power generation, if it breaks down, it could affect wind power generation in the area.
Analysis: The big windmill on the mountain is also called a wind turbine. Its function is to convert the kinetic energy of the wind into mechanical energy. This mechanical energy causes the generator to produce electricity, thereby converting it. in electrical energy.
Since the wind turbine's fan blades are so narrow, will much of the wind's energy be missed? For what ?
The reason why wind turbines for wind power generation have three blades;
1. Three blades can improver the wind sweeping efficiency, and the three blades can also maintain the balance of wind energy. wind turbine.
2. The number of blades of the wind turbine is 3, which is the optimal result under the overall consideration and action of several factors, mainly optimization and balance between aerodynamic efficiency and structural complexity.
3. The three-part page turner determines low manufacturing and maintenance costs and ease of use.
I feel like I've said it all, but I can't seem to get the point. Is the so-called size comparable to the electric fan? There are two types of fan leaves. I forgot the specific theory, but the purpose of the fan is to generate more wind, and the purpose of wind power generation is to use more of the wind energy and generate a force that turns it. , which is the direction generated byr the curvature of the fan leaves. But there is a problem with wind power: the area it blows is very large. If the fan area is too large, firstly, the thrust force is too large and the wind turbine will fall. is too weak (fan surface area is too large). Most wind energy cannot be converted into lateral thrust). How to calculate it specifically can be read in a document. Last year I built a small wind turbine. This part is part of the theory, but I really don't remember it clearly. The fan blades used are only 12% efficient. Is it very big? Its lateral pressure is too low compared to the vertical pressure. Additionally, the purpose of the fan is to generate wind over a larger area. As the area is not enough, the head swing function is added, I put this thing on the wind turbine without discussing whetherit can be erected (it is possible). this can be done by digging a deeper foundation and changing the support material, reduce the fan area - the whole science is about sacrificing some part of performance in exchange for the most desired results), but efficiency is really too much. weak. As I said before, the little wind power I produced. The generator efficiency is only about 12%, which is far from the highest level of 50+! !
